UNITED STATES DISTRICT COURT 

EASTERN DISTRICT OF MICHIGAN 

SOUTHERN DIVISION 

In this case, thousands of prisoners claim that the Michigan Department of 

Corrections provides them with constitutionally inadequate dental care. Over two 

years ago, the Court certified several classes of prisoners, with each class challenging 

a different aspect of the MDOC’s dental care. See generally Dearduff v. Washington, 

330 F.R.D. 452 (E.D. Mich. 2019). One certified class, Class IIA, challenges the tools 

the MDOC uses to diagnose periodontal disease. Another certified class, Class IIB, 

challenges the adequacy of MDOC’s treatment of periodontal disease. In seeking class 

certification, Plaintiffs wanted the Court to certify a class of all prisoners in the 

MDOC’s custody—over 37,000 prisoners—and claimed that this Court could 

productively adjudicate each of their Eighth Amendment claims at once. But, for

OPINION AND ORDER GRANTING IN PART AND DENYING IN PART 

PLAINTIFFS’ MOTION SEEKING PARTIAL RELIEF FROM THE 

COURT’S CLASS CERTIFICATION ORDER [302] 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8303 Filed 08/20/21 Page 1 of 27

reasons explained in detail, the Court declined Plaintiffs’ request and limited both 

Class IIA and Class IIB to a subset of MDOC prisoners. See Dearduff, 330 F.R.D. at 

468–73. 

After additional discovery, Plaintiffs now ask the Court to reconsider its prior 

ruling and expand Class IIA and Class IIB to include all prisoners in the MDOC’s 

custody. For the reasons that follow, the Court will deny Plaintiffs’ request to expand 

Class IIA but grant in part Plaintiffs’ request to expand Class IIB. 

To better appreciate Plaintiffs’ request to expand the two previously certified 

classes, it helps to know a bit about periodontal disease, how it is diagnosed, and how 

it is treated. 

“Periodontal disease is an inflammatory disease of the supporting tissues of 

the teeth,” including the gums and periodontal ligament. (ECF No. 302-8, 

PageID.7699.) The disease is progressive; the rate of progression depends on several 

factors, including age, diabetes, and tobacco use. (ECF No. 302-8, PageID.7706.) 

Under one classification system, a person can have healthy gums, gingivitis, early 

periodontitis, moderate periodontitis, or advanced periodontitis. (See ECF No. 302-8, 

PageID.7716 (equating Periodontal Screening and Recording scores with “gingivitis,” 

“early,” “moderate,” and “advanced”); cf. ECF No. 302-8, PageID.7705 (using “Stage” 

and “Grade” to classify disease).) On the less severe end of the spectrum are people 

with healthy gums and gingivitis. Gingivitis “is a reversible inflammation of the soft 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8304 Filed 08/20/21 Page 2 of 27
3 

tissue that does not result in the loss of periodontal structures.” (ECF No. 302-8, 

PageID.7701.) As periodontal disease progresses, the supporting tissues of the tooth 

begin to separate from the tooth forming pockets between the tooth and gums: 

(ECF No. 302-8, PageID.7699.) Calculus (hardened plaque) and bacteria can collect 

inside these pockets, and the bone surrounding the teeth can erode. (See ECF No. 

302-8, PageID.7706.) If allowed to progress, periodontitis can result in tooth loos or 

an abscess. (ECF No. 302-8, PageID.7718.) The severity of periodontal disease can 

vary throughout the mouth; the structures supporting one or two teeth might be 

suffering from say, advanced periodontitis, but the structures supporting other teeth 

are only affected by gingivitis. (See ECF No. 302-8, PageID.7702 (describing method 

of dividing the mouth into six parts and measuring periodontal health in each part); 

ECF No. 302-8, PageID.7719 (indicating that periodontal treatment can be provided 

for a single “quadrant” of the mouth); ECF No. 315-9, PageID.7970 (indicating that 

dentist should specify areas of mouth requiring periodontal treatment).) Periodontitis 

is common: approximately 45% of adults over age of 30 have some level of 

periodontitis. (ECF No. 302-8, PageID.7698.) But “the prevalence of moderate to 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8305 Filed 08/20/21 Page 3 of 27
4 

severe periodontal disease in correctional populations is higher than in the free 

population.” (ECF No. 302-8, PageID.7701.) 

Plaintiffs and one of their opinion witnesses, Jay Schulman, DMD, assert that 

intraoral x-rays and periodontal probing are necessary to accurately diagnose 

periodontal disease. Schulman says that extraoral images from a panoramic x-ray 

lack the detail necessary to “diagnose caries [i.e., tooth decay] or document 

periodontal bone loss”; in contrast, intraoral x-rays “provide a considerable amount 

of information about the periodontium that cannot be obtained by any other noninvasive means.” (ECF No. 302-8, PageID.7703.) The second diagnostic tool, 

periodontal probing, involves measuring pocket depth using a probe. (ECF No. 302-

8, PageID.7699–7700.) Probing not only helps determine the severity of periodontitis 

for a particular area of the mouth, but also helps determine varying severity 

throughout the mouth. (See ECF No. 302-8, PageID.7702.) Charting the pocket-depth 

measurements permits periodontal disease to be monitored over time. (ECF No. 302-

8, PageID.7700.) 

The treatment for periodontal disease depends on its severity. For gingivitis, 

which is on the low end of the severity spectrum, instruction on proper oral hygiene 

and a prophylaxis is often adequate treatment. (See ECF No. 302-8, PageID.7711.) A 

prophylaxis or “prophy” is a dental cleaning and, according to Schulman, is distinct 

from a “scaling and root planing,” which is a more involved procedure usually 

requiring local anesthesia. (ECF No. 302-8, PageID.7719.) Schulman states that 

scaling and root planing “is an appropriate treatment when there is loss of 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8306 Filed 08/20/21 Page 4 of 27
5 

attachment [between periodontal tissues and the tooth] in early, moderate or 

advanced periodontitis.” (ECF No. 315-11, PageID.8020; see also ECF No. 302-8, 

PageID.7711.) Scaling includes scraping the tooth above and below the gum line 

(inside the pockets) to remove calculus and bacteria. (See ECF No. 302-8, 

PageID.7719–7720.) Root planing includes smoothing the root to give the soft tissues 

a better chance of reattaching to the tooth. (See id.) According to Plaintiffs, in addition 

to scaling and root planing, follow-up treatment may be necessary to effectively treat 

periodontitis. (See ECF No. 315-9, PageID.8012.) 

In 2019, this Court certified two classes relating to periodontal disease. See 

Dearduff v. Washington, 330 F.R.D. 452, 460, 468–473 (E.D. Mich. 2019). 

One class, Class IIA, claimed that the tools the Michigan Department of 

Corrections used to diagnose periodontal disease were inadequate. See id. at 460. 

When a prisoner enters into the MDOC system, an intake dental exam is performed. 

During this intake exam, dentists use a prisoner’s oral health history, a visual 

examination, and panoramic, i.e., extraoral, x-rays to determine the stage of a 

prisoner’s periodontal disease. (See ECF No. 302-8, PageID.7712; ECF No. 242-8, 

PageID.6527.) At later exams, the MDOC may take intraoral x-rays. (ECF No. 315-

9, PageID.7979.) Prisoners in Class IIA claimed (and still claim) that intraoral x-rays 

and periodontal probing are necessary to accurately diagnose periodontal disease. See 

Dearduff, 330 F.R.D. at 460; (ECF No. 315-9, PageID.7970). Class IIA claimed (and 

still claims) that without intraoral x-rays and periodontal probing, they are at risk of 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8307 Filed 08/20/21 Page 5 of 27
6 

having their periodontal disease underdiagnosed. See Dearduff, 330 F.R.D. at 460; 

(ECF No. 315-9, PageID.7970). For instance, say Plaintiffs, without intraoral x-rays 

and periodontal probing, an MDOC dentist might diagnose a prisoner with early 

periodontitis when, in fact, the prisoner has moderate periodontitis. This 

underdiagnosis leads to the lack of proper treatment which, in turn, leads to serious 

harm under the Eighth Amendment, those in Class IIA argued. See Dearduff, 330 

F.R.D. at 460. In this Court’s class-certification opinion, Class IIA was defined as 

“[a]ll prisoners incarcerated in an MDOC correctional facility who have caries that 

have reached the dentin or have early (or worse) periodontitis.” Id. (Dentin is bony 

tissue of the tooth beneath the enamel.) 

The Court also certified Class IIB, which claimed that the MDOC did not 

adequately treat periodontal disease. Dearduff, 330 F.R.D. at 461. Plaintiffs wanted 

this treatment class to include all prisoners in the MDOC’s custody. See id. at 459–

61. Although the MDOC had (and still has) a systemwide policy of not providing 

periodontal services to a prisoner in his or her first two years in prison, see Michigan 

Department of Corrections, Policy Directive 04.06.150 (May 2018), 

https://perma.cc/S3Z8-SN4E, the Court found that there was an exception to this 

policy for prisoners with more severe periodontitis, see Dearduff, 330 F.R.D. at 468. 

In making that finding, the Court relied on a memorandum from MDOC Dental 

Director Jong Choi and a proffer from Defendants indicating that prisoners with 

“unstable” moderate periodontitis and advanced periodontitis were receiving 

necessary periodontal treatment. Because Class IIB claimed that the MDOC was 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8308 Filed 08/20/21 Page 6 of 27
7 

providing constitutionally inadequate periodontal treatment, the Court excluded 

prisoners with unstable moderate periodontitis and advanced periodontitis from 

Class IIB. See Dearduff, 330 F.R.D. at 461. 

Plaintiffs have now filed a motion pursuant to Federal Rule of Civil Procedure 

54(b) asking this Court to reconsider how it defined Class IIA and Class IIB. 

Regarding Class IIA, Plaintiffs argue that all prisoners, including those with 

healthy gums and gingivitis, need intraoral x-rays and periodontal probing for proper 

diagnoses of their periodontal health. (ECF No. 315, PageID.7917–7918.) So, argue 

Plaintiffs, Class IIA should be expanded to include those with healthy gums and 

gingivitis, i.e., Class IIA should include all MDOC prisoners. (See id.) 

Regarding Class IIB, Plaintiffs argue that dental science does not support a 

distinction between “stable” and “unstable” moderate periodontitis and so the Court 

was wrong to define Class IIB using the term “stable.” (ECF No. 302, PageID.7646–

7652; ECF No. 315, PageID.7909–7917.) Plaintiffs also claim that evidence collected 

after this Court issued its class-certification opinion shows that prisoners with 

periodontitis (including those with moderate or advanced periodontitis) are not being 

provided scaling and root planing, a necessary treatment. (ECF No. 315, 

PageID.7922.) So Plaintiff would like the Court to expand Class IIB to include all 

MDOC prisoners. (Id.) 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8309 Filed 08/20/21 Page 7 of 27
8 

Plaintiffs also ask this Court to find that Anthony Richardson, a named 

plaintiff who represents Class IIA, can also represent Class IIB. (ECF No. 315, 

PageID.7926.) 

Often, not a whole lot needs to be said about the legal standard governing a 

motion. But motions pursuant to Rule 54(b) asking a Court to reconsider a ruling 

under Rule 23 are not garden variety. So the Court will say a bit more about the 

standard governing Plaintiffs’ request for relief. 

In substance, Plaintiffs ask this Court to reconsider an order that did not end 

the case. Typically, that is the office of Eastern District of Michigan Local Rule 7.1(h). 

But that rule gives the parties at most 14 days to file a motion for reconsideration, 

and, here, Plaintiffs have sought reconsideration far beyond that timeframe (more on 

this in a moment). Presumably for this reason, Plaintiffs have invoked Federal Rule 

of Civil Procedure 54(b). 

Rule 54(b) also allows the Court to revise non-final orders. In states in relevant 

part, “any order or other decision, however designated, that adjudicates fewer than 

all the claims or the rights and liabilities of fewer than all the parties . . . may be 

revised at any time before the entry of a judgment[.]” Fed. R. Civ. P. 54(b). 

“Traditionally, courts will find justification for reconsidering interlocutory orders 

when there is (1) an intervening change of controlling law; (2) new evidence available; 

or (3) a need to correct a clear error or prevent manifest injustice.” Rodriguez v. 

Tennessee Laborers Health & Welfare Fund, 89 F. App’x 949, 959 (6th Cir. 2004). For 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8310 Filed 08/20/21 Page 8 of 27
9 

convenience, the Court will refer to these as the “traditional justifications for Rule 

54(b) relief.” 

According to Defendants, Plaintiffs “have not offered any new evidence that 

would support this Court reconsidering its opinion and order.” (ECF No. 324, 

PageID.8231.) But Plaintiffs say, “At the time of this Court’s ruling on the class 

certification motion, Plaintiffs were still engaged in discovery and, most importantly, 

it had not yet received 100 dental records of class members for review.” (ECF No. 307, 

PageID.7810.) 

At the outset, the Court does question the timing of Plaintiffs’ motion and the 

manner in which they collected evidence to support it. Even setting aside the fact that 

Plaintiffs filed this case seven years ago, this Court issued its class-certification 

opinion over two years ago, in February 2019. Yet Plaintiffs’ current Rule 54(b) 

motion was not filed until September 2020—18 months after that opinion issued. And 

even then, Plaintiffs’ motion was not supported in the way it is now. In June 2021—

two years after this Court’s certification opinion—Plaintiffs filed a supplement to 

their Rule 54(b) motion that included significant, additional evidence supporting 

expansion of Class IIA and Class IIB. (ECF No. 315.) 

In this vein, the Court is compelled to comment on the briefing associated with 

Plaintiffs’ motion to expand Class IIA and Class IIB. The initial motion was 19 pages 

(ECF No. 302) and then Plaintiffs filed an eight-page reply brief (ECF No. 307). 

Plaintiffs supplemental brief (filed over eight months after their motion) is another 

27 pages. Not only does 27 pages exceed the page limits in the Local Rules, the 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8311 Filed 08/20/21 Page 9 of 27
10 

supplemental brief contains many redundant statements. Moreover, Plaintiffs now 

seek leave to file a nine-page reply to Defendants’ response to their supplemental 

brief (which would bring Plaintiffs’ total briefing on three limited issues to 63 pages). 

(ECF No. 315.) Not only that, Plaintiffs’ request to file a reply has spawned briefing 

about briefing. (See ECF Nos. 328, 329.) The Court urges all parties to think carefully 

about their arguments and to distill them down to their essential points. Although 

the Court would be justified in denying Plaintiffs’ request to file a reply, because its 

content does not alter the Court’s decision, the motion is granted. 

Having addressed the briefing, the Court returns to the proper legal standard. 

Plaintiffs ask this Court to expand two previously certified classes and to make 

Richardson a class representative of one class. Because modifying class definitions is 

almost the entirety of the relief Plaintiffs seek, the Court does not believe that 

Plaintiffs must satisfy the traditional justifications for Rule 54(b) relief. As the Sixth 

Circuit has explained, “district courts have broad discretion to modify class 

definitions, so the district court’s multiple amendments merely showed that the court 

took seriously its obligation to make appropriate adjustments to the class definition 

as the litigation progressed.” Powers v. Hamilton Cty. Pub. Def. Comm’n, 501 F.3d 

592, 619 (6th Cir. 2007). In fact, Rule 23(c)(1)(C), rather than Rule 54(b), is the 

preferred vehicle for Plaintiffs’ motion: “An order that grants or denies class 

certification may be altered or amended before final judgment.” Fed. R. Civ. P. 

23(c)(1)(C); see also Richardson v. Byrd, 709 F.2d 1016, 1019 (5th Cir. 1983) (“Under 

Rule 23 the district court is charged with the duty of monitoring its class decisions in 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8312 Filed 08/20/21 Page 10 of 27
11 

light of the evidentiary development of the case. The district judge must define, 

redefine, subclass, and decertify as appropriate in response to the progression of the 

case from assertion to facts.”). 

Accordingly, the Court will assess Plaintiffs’ request for expansion of Class IIA 

and Class IIB under Rule 23(c)(1)(C). But given that this case is now seven years old, 

and that Plaintiffs had plenty of opportunity to collect evidence for their proposed 

classes, the Court will not consider any further motions by Plaintiffs to alter the scope 

of the classes or alter the legal claims that each class pursues. 

The Court starts with Plaintiffs’ request to expand Class IIA, then addresses 

Plaintiffs’ like request for Class IIB. 

Before examining the specifics of Plaintiffs’ request to expand Class IIA, the 

Court clarifies the scope of Class IIA as currently defined. In stating that Class IIA 

consisted of all prisoners “who have caries that have reached the dentin or have early 

(or worse) periodontitis,” the Court perhaps left the scope of Class IIA susceptible to 

two interpretations. One is that Class IIA only includes prisoners that MDOC 

dentists—without intraoral x-rays or periodontal probing—have diagnosed as having 

early, moderate, or advanced periodontitis (or caries that have reached the dentin). 

The other interpretation is that the class includes all prisoners who—accurately 

diagnosed—have early, moderate, or advanced periodontitis (or caries that have 

reached the dentin). The Court now makes clear that this second interpretation of 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8313 Filed 08/20/21 Page 11 of 27
12 

Class IIA is the proper one. And to the extent that the Court’s clarification raises a 

question about which prisoners are in Class IIA (after all, the claim is that the MDOC 

often underdiagnoses periodontal disease), the Court notes that all the certified 

classes in this case are of the Rule 23(b)(2) variety, and there is no ascertainably 

requirement associated with Rule 23(b)(2) classes. See Cole v. City of Memphis, 839 

F.3d 530, 540, 542 (6th Cir. 2016) (“Because the focus in a (b)(2) class is more heavily 

placed on the nature of the remedy sought, and because a remedy obtained by one 

member will naturally affect the others, the identities of individual class members 

are less critical in a (b)(2) action than in a (b)(3) action.” (internal quotation marks 

omitted)). 

With that clarification, the Court turns to Plaintiffs’ request to expand 

Class IIA. The members of Class IIA claim that to accurately diagnose periodontal 

disease, the MDOC needs to use intraoral x-rays and periodontal probing. But, 

according to Plaintiffs, it is not just prisoners with early, moderate, or advanced 

periodontitis that require intraoral x-rays and periodontal probing—it is all 

prisoners. Plaintiffs assert, “Dentists use periodontal probing and charting to screen 

all patients, whether healthy or periodontally involved to establish a baseline 

measurement for future recordings and to confirm health status.” (ECF No. 315, 

PageID.7918.) “Thus,” say Plaintiffs “all patients should be probed and charted, not 

just early or worse periodontal patients, to prevent progression of further disease and 

keep an accurate reliable record of any possible disease progression over time and to 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8314 Filed 08/20/21 Page 12 of 27
13 

determine presence or absence of disease common to all.” (Id.) So Plaintiffs propose 

that this Court expand Class IIA to include all prisoners. 

Plaintiffs’ argument focuses heavily on what they believe is necessary 

healthcare (intraoral x-rays and probing). But Plaintiffs do not focus enough on what 

is necessary for class certification. Rather than asking what people need for good 

dental health, the more pertinent question right now is whether the legal claims of a 

class consisting of every MDOC prisoner—over 37,000 people with varying 

periodontal health—can be productively litigated at once. 

Rule 23 helps answer that question. Although commonality and typicality 

under Rule 23 do not require that all class members have identical legal claims, they 

do require that the overwhelming majority of class members’ legal claims be similar 

in material ways. In particular, class members’ “claims must depend upon a common 

contention . . . [that is] capable of classwide resolution.” Wal-Mart Stores, Inc. v. 

Dukes, 564 U.S. 338, 350 (2011). In other words, the Court must be able to “resolve 

an issue that is central to the validity of each one of the [class members’] claims in 

one stroke.” Id.; see also Sprague v. Gen. Motors Corp., 133 F.3d 388, 397 (6th Cir. 

1998) (“What we are looking for is a common issue the resolution of which will 

advance the litigation.”). 

Here, if Class IIA were expanded to include prisoners with healthy gums, the 

Court would not be able to resolve an issue that substantially advances the claims of 

all (or, at least, an overwhelming majority of) class members “in one stroke.” To 

succeed on an Eighth Amendment claim, a prisoner must show that a prison 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8315 Filed 08/20/21 Page 13 of 27
14 

healthcare provider was “deliberately indifferent” to his or her “serious medical 

need[.]” Richmond v. Huq, 885 F.3d 928, 937 (6th Cir. 2018). And deliberate 

indifference means that the MDOC policymaker “subjectively perceived facts from 

which to infer substantial risk to the prisoner, that he did in fact draw the inference, 

and that he then disregarded that risk by failing to take reasonable measures to abate 

it.” Rhinehart v. Scutt, 894 F.3d 721, 738 (6th Cir. 2018) (internal quotation marks 

omitted). For prisoners with healthy gums, whom Plaintiffs wish to include in Class 

IIA, the lack of intraoral x-rays and probing does not deprive them of immediately 

needed treatment. But prisoners with early periodontitis, who are also members of 

Class IIA, have an immediate need for treatment (e.g., scaling and root planing). So 

the failure to use intraoral x-rays and probing affects these two groups of prisoners 

quite differently: those with healthy gums want the two diagnostic tools to establish 

an accurate baseline of periodontal health; but those with early periodontitis would 

like the two diagnostic tools so they can be accurately diagnosed for immediate 

treatment. So the “medical need” is materially different. Moreover, it is likely that 

the MDOC policymaker’s subjective appreciation of the risk of harm to the two groups 

of prisoners is different. Thus, the Court is not persuaded that analyzing the Eighth 

Amendment claim of a prisoner with healthy gums will materially advance the 

resolution of an Eighth Amendment claim brought by a prisoner with early 

periodontitis, or vice versa. 

Next consider Plaintiffs’ proposal to expand Class IIA to include prisoners with 

gingivitis. True, if Plaintiffs’ are correct that intraoral x-rays and probing are 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8316 Filed 08/20/21 Page 14 of 27
15 

necessary to accurately diagnose periodontal disease, then prisoners with gingivitis 

and prisoners with periodontitis are both at risk of underdiagnosis. But gingivitis 

may not be a “serious medical need” in the Eighth Amendment sense whereas 

periodontitis may be. And even if both conditions satisfy the objective element of an 

Eighth Amendment claim, consider the subjective element. MDOC Dental Director 

Choi and MDOC Director Washington may appreciate that a prisoner with 

periodontitis has a serious need for treatment while they may not appreciate that a 

prisoner with gingivitis has a serious need for treatment. Or more succinctly: it may 

well be that MDOC policymakers perceive the harm from underdiagnosed gingivitis 

as much less severe than the harm from underdiagnosed periodontitis. 

The Court repeatedly used “may” in the prior paragraph. And it is true that 

the Court has only identified potential differences in the Eighth Amendment claims 

brought by those with gingivitis and those with periodontitis. But it is “the party 

seeking class certification”—not the Court—“that bears the burden of affirmatively 

demonstrating compliance with Rule 23.” Sandusky Wellness Ctr., LLC v. ASD 

Specialty Healthcare, Inc., 863 F.3d 460, 466–67 (6th Cir. 2017) (internal quotation 

marks and alterations omitted). Yet, in their three principal briefs (spanning 54 

pages), Plaintiffs make no attempt to address Rule 23’s requirements or Wal-Mart. 

(See generally ECF No. 302, 307, 315.) True, the phrase “one stroke” makes an 

appearance in Plaintiffs’ fourth brief (which they needed leave to file). But even then 

the discussion is both cursory and not on point. (See ECF No. 325-1, PageID.8279.) 

Plaintiffs simply assert that the Court can craft a remedy that cures the harm in “one 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8317 Filed 08/20/21 Page 15 of 27
16 

stroke.” (Id.) But that is not what Rule 23 commonality demands: it must be that an 

issue shared among the claims of the thousands of prisoners in Class IIA can be 

resolved at once. See Wal-Mart, 564 U.S. at 350. 

In short, Plaintiffs have not persuaded the Court that if Class IIA were to 

include all prisoners, the Court would be able to “resolve an issue that is central to 

the validity of each one of the [members’] claims in one stroke.” See Wal-Mart, 564 

U.S. at 350. Accordingly, Plaintiffs’ motion, insofar as it asks the Court to expand 

Class IIA, will be denied. 

Plaintiffs also ask the Court to expand Class IIB to include all MDOC 

prisoners. 

1. 

To fully appreciate Plaintiffs’ request, some additional background is 

necessary. 

As noted, the Court previously defined Class IIB as follows: “All prisoners 

incarcerated in an MDOC correctional facility with healthy gums, gingivitis, early 

periodontitis, and stable moderate periodontitis.” Dearduff v. Washington, 330 F.R.D. 

452, 472 (E.D. Mich. 2019). The Court did not include prisoners with more severe 

periodontitis—i.e., “unstable” moderate periodontitis or advanced periodontitis—in 

Class IIB. The Court excluded these prisoners from the class because Defendants 

indicated that MDOC was providing them with periodontal treatment, and the 

members of Class IIB claimed that the MDOC was not providing prisoners

periodontal treatment (or, at least, not providing adequate periodontal treatment). 

Id. at 469. 

The Court’s determination that the MDOC provided those with unstable 

moderate periodontitis and advanced periodontitis with treatment was based on a 

memorandum drafted by MDOC Dental Director Jong Choi and a proffer Defendants 

made in their brief opposing class certification. Choi’s memo stated that because 

periodontitis progressed slowly, “there is no harm done by not specifically treating, 

beyond self-care, early stage periodontal conditions during the first two years of 

incarceration.” (ECF No. 246-6, PageID.7050.) “Similarly,” Choi continued, “moderate 

periodontitis, if stable with self-care, will not require intervening dental care in the 

first two years of incarceration to prevent the condition from becoming advanced.” 

(Id. (emphasis added).) But, said Choi, “unstable moderate periodontal condition 

should be identified for stabilization care sufficient to attempt to change the condition 

from unstable to stable.” (Id. (emphasis added).) As for advanced periodontitis, Choi’s 

memo stated that these prisoners had “experienced too much bone loss to save the 

affected tooth or teeth,” and so extraction was recommended to prevent infection. (Id.) 

In addition to Choi’s memo, in opposing class certification, Defendants made the 

following proffer in their brief: “Within the range of identifiable stages of 

periodontitis, as determined by degree of bone loss, those with moderate stage 

periodontitis whose condition is unstable will receive stabilization referral for 

periodontal treatment, as appropriate, including debridement and/or root planing 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8319 Filed 08/20/21 Page 17 of 27
18 

and scaling, with follow up sufficient to stabilize the condition.” (ECF No. 246, 

PageID.6977 (emphasis added).) 

Given Choi’s memo and the proffer by Defendants’ counsel, the Court was “not 

persuaded that the MDOC has a policy or systemwide practice of not providing 

appropriate treatment for those with moderate or advanced periodontal disease.” 

Dearduff, 330 F.R.D. at 469. So the Court excluded prisoners with unstable moderate 

periodontitis or advanced periodontitis from Class IIB. But the Court added, 

“[s]hould Plaintiffs prove that Defendants’ claim about the provision of root planing 

and scaling (with follow-up care) is not accurate, the Court will revisit this issue.” Id.

2. 

Plaintiffs now ask the Court to revisit this issue. 

But one of Plaintiffs’ arguments places too much weight on the Court’s word 

choice and does not address the Court’s more fundamental point. Plaintiffs spend a 

lot of pages attempting to prove that the distinction between “unstable” and “stable” 

moderate periodontitis is untenable. (ECF No. 302, PageID.7646–7652; ECF No. 315, 

PageID.7909–7917.) But even if Choi was wrong about the stability of moderate 

periodontitis (and thus the Court was wrong to use the word “stable” to define Class 

IIB), the more fundamental question is whether MDOC adequately treats prisoners 

with more severe cases of periodontitis. If so, then these prisoners should not be part 

of Class IIB. After all, Class IIB claims that MDOC inadequately treats periodontal 

disease. (And so much so, that it is an Eighth Amendment violation.) 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8320 Filed 08/20/21 Page 18 of 27
19 

Apart from attacking the “stable” and “unstable” distinction, Plaintiffs ask the 

Court to expand Class IIB based on evidence discovered after class certification. They 

argue that this evidence shows that, contrary to Choi’s memo and Defendants’ proffer, 

MDOC prisoners with periodontitis do not receive scaling or root planing and 

therefore they still need that relief. (See ECF No. 315, PageID.7919–7922.) After the 

Court’s certification opinion, it appears that Schulman (one of Plaintiffs’ opinion 

witnesses) randomly selected and reviewed the dental charts of 100 prisoners who 

were on a wait list for a filling. (See ECF No. 315-9, PageID.7989.) (The Court says 

“it appears” that Shulman randomly selected 100 dental charts because his 

description of his selection methodology is not clear to the Court. (ECF No. 302-8, 

PageID.7721.)) Schulman’s review of the 100 dental charts revealed that 61 of the 

prisoners had been diagnosed with early, moderate, or advanced periodontal disease. 

(ECF No. 315-11, PageID.8020.) And, based on notations in the charts, Schulman 

concluded that MDOC dentists only ever prescribed these 61 prisoners a prophy, i.e., 

a cleaning. (Id.) So based on the dental charts, it would seem that the MDOC does 

not provide prisoners with early, moderate, or advanced periodontitis with a scaling 

and root planing. And this would be contrary to Choi’s memo and Defendants’ proffer 

at class certification. 

But the dental charts do not tell the whole story; other evidence suggests that 

some prisoners receive a scaling and root planing even if their dental charts only state 

“prophy.” For one, Dental Director Choi indicated that the terms “prophy” and “root 

planing and scaling” were, at least at one point during his tenure at MDOC, 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8321 Filed 08/20/21 Page 19 of 27
20 

“interchangeably used.” (ECF No. 315-5, PageID.7951.) And Dalton Sanders, an 

MDOC dentist, testified that “root planing and scaling is part of adult prophylaxis if 

needed.” (ECF No. 315-9, PageID.7986.) Similarly, Gloria Smith, another MDOC 

dentist, indicated that if she ordered a cleaning known as a “debridement,” her 

hygienist would know that includes root planing and scaling. (ECF No. 307-4, 

PageID.7828.) Indeed, one MDOC hygienist testified that “a prophylaxis is a 

debridement, a scaling and root planing, and a rubber cup polish,” and another 

MDOC hygienist testified that she provides “scaling and root planing, if it’s 

necessary.” (ECF No. 315-9, PageID.7986.) Thus, the absence of a notation for scaling 

and root planing on the dental charts Shulman reviewed does not conclusively 

establish that the MDOC does not provide prisoners with periodontitis with scaling 

and root planing. Indeed, Schulman opines that “the [MDOC] dentist prescribes 

‘prophy’ and the dental hygienist decides whether to perform a periodontal scaling or 

scaling and root planing sua sponte.” (ECF No. 315-9, PageID.7970.) 

Granting that some prisoners who are prescribed a “prophy” nonetheless 

receive the necessary scaling and root planing, the Court is persuaded, for purposes 

of class certification, that there are a substantial number of prisoners who have early, 

moderate, or advanced periodontitis and who are not receiving scaling and root 

planing. To start, the MDOC undoubtedly employs more hygienists than the few who 

have testified that they provide scaling and root planing when a dentist orders a 

prophy. So the hygienists’ testimony does not establish that the MDOC consistently

provides scaling and root planing to prisoners with periodontitis. Second, Schulman 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8322 Filed 08/20/21 Page 20 of 27
21 

says that anesthesia is generally used to perform scaling and root planing, yet, “none 

of the randomly selected records [he] reviewed had documented codes [for anesthesia] 

in conjunction with a prophylaxis.” (ECF No. 315-9, PageID.7985; but see ECF No. 

315-9, PageID.8011 (noting that anesthesia was “rarely” documented).) As such, 

Schulman says it “strains credulity” that the notation of a “prophy” on the dental 

charts could be referring to a scaling and root planing. (ECF No. 315-9, PageID.7985.) 

Third, there is evidence that under Michigan law, dentists must prescribe scaling and 

root planing before a hygienist can provide that treatment. Dental Director Choi 

acknowledged that it would violate Michigan law for a hygienist to perform root 

planing and scaling when a dentist only orders a prophy. (ECF No. 315-5, 

PageID.7952.) And another of Plaintiffs’ opinion witnesses, Stephen Harrel, DDS, 

testified that a “dentist needs to make the diagnosis and then treatment plan for root 

planing and scaling” and that “hygienists should not do that on their own.” (ECF No. 

315-10, PageID.8017.) If a hygienist cannot lawfully provide scaling and root planing 

until a dentist orders that procedure, that would suggest that MDOC hygienists do 

not consistently perform a scaling and root planing when a dentist orders a prophy. 

To sum up so far, Plaintiffs have shown that the MDOC has a systemwide 

practice of only prescribing a “prophy” for prisoners with early, moderate, or advanced 

periodontitis. And while some MDOC hygienists perform a scaling and root planing 

when only a prophy is ordered, the Court is not now persuaded that is consistently 

the case. Accordingly—for purposes of class certification—the Court finds that a 

significant number of MDOC prisoners with early, moderate, or advanced 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8323 Filed 08/20/21 Page 21 of 27
22 

periodontitis are not receiving necessary scaling and root planing and necessary 

follow-up care. 

3. 

The Court will accommodate this new finding by redefining Class IIB and 

creating a new class for prisoners not receiving scaling and root planing. Class IIB 

will be redefined as follows: “All prisoners incarcerated in an MDOC correctional 

facility with healthy gums or gingivitis.” And the new class, Class IIC, will be defined 

as follows: “All prisoners incarcerated in an MDOC correctional facility with early, 

moderate, or advanced periodontitis who have not received all necessary scaling and 

root planing and follow-up treatment.” 

Both these classes satisfy Rule 23’s requirements for certification. Start with 

reconstituted Class IIB. This class has shrunk, and so the diversity in dental health 

among members of Class IIB is now less than before. It follows that the Eighth 

Amendment claims of those in Class IIB are now more similar than before: there is 

less diversity in both the type of harm and risk of harm from inadequate periodontal 

treatment. So, with one exception, the analysis this Court provided in its classcertification opinion suffices to show that reconstituted Class IIB meets Rule 23’s 

demands. See Dearduff, 330 F.R.D. at 469–70. 

The one exception: Rule 23(a)(4)’s requirement that “the representative parties 

will fairly and adequately protect the interests of the class.” The Court previously 

found that Melvin Bownes could represent Class IIB. See Dearduff, 330 F.R.D. at 470. 

Although the Court does not have updated dental records for Bownes, Bownes’ 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8324 Filed 08/20/21 Page 22 of 27
23 

periodontal disease appears to be more severe than gingivitis. (See ECF No. 315-9, 

PageID.8007.) But, as redefined, Class IIB consists of those prisoners with healthy 

gums and gingivitis. So Bownes might not be a proper representative of redefined 

Class IIB. Zehentbauer Fam. Land, LP v. Chesapeake Expl., L.L.C., 935 F.3d 496, 503 

(6th Cir. 2019) (“[A] class representative must be part of the class and possess the 

same interest and suffer the same injury as the class members.” (internal quotation 

marks omitted)). 

Fortunately for Plaintiffs, another named plaintiff in this case, Anthony 

Richardson, can also represent redefined Class IIB. Although the Court also does not 

have recent dental records for Richardson, as of April 2019, Richardson was 

diagnosed with “generalized gingivitis.” (ECF No. 315-9, PageID.8006.) True, on 

earlier occasions, Richardson, like Bownes, was diagnosed with more severe 

periodontal disease. But as this Court currently understands periodontal disease, it 

may be possible to have gingivitis in one area of the mouth and periodontitis in 

another. (See ECF No. 315-2, PageID.7931 (MDOC dentist indicating that 

periodontal disease can be “localized” to a particular area of the mouth); ECF No. 315-

9, PageID.7972 (“Periodontal lesions may be generalized or localized in a quadrant or 

tooth.”); ECF No. 315-9, PageID.7970 (indicating that a treatment plan should specify 

the areas of the mouth requiring scaling and root planing).) Indeed, it may be that 

gingivitis, broadly defined as “inflammation of the soft tissue” (ECF No. 302-8, 

PageID.7701), is present around an area of the mouth with periodontitis. Accordingly, 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8325 Filed 08/20/21 Page 23 of 27
24 

on the record now before the Court, Richardson is an adequate representative for 

Class IIB. 

Class IIC also meets Rule 23’s requirements. Each prisoner in Class IIC 

asserts the same medical need—scaling and root planing and follow-up care—and 

each faces a similar risk of similar harm if they are not provided that treatment. True, 

the summary-judgment or trial record might show that those with say, advanced 

periodontitis have a “serious medical need” under the Eighth Amendment while those 

with say, early periodontitis do not. Or the proofs might ultimately show that Dental 

Director Choi and Director Washington appreciate that prisoners with advanced 

periodontitis are at substantial risk of harm without scaling and root planing but do 

not have that same appreciation for prisoners with early periodontitis. So it is 

possible that the Eighth Amendment claims of those in Class IIC will not all rise and 

fall together. But Schulman has opined that even those with early periodontitis 

should receive a scaling and root planing (ECF No. 315-9, PageID.7972) and it 

appears that by early periodontitis, there is already some bone loss (ECF No. 315-9, 

PageID.7983). So, for now, the Court believes that those in Class IIC face similar 

enough risk of similar enough harm that at least one central issue underlying all of 

their Eighth Amendment claims can be resolved in “one stroke.” 

As for class representatives, Richardson will also adequately represent Class 

IIC. It is true that in 2012 and 2014, Richardson received scaling (and possibly root 

planing) for his periodontal disease. (ECF No. 315-9, PageID.8006.) But in October 

2018, Richardson still had moderate periodontitis and it is not at all clear that he 

Case 2:14-cv-11691-LJM-MKM ECF No. 331, PageID.8326 Filed 08/20/21 Page 24 of 27
25 

continued to receive scaling and root planing. (See id.) (As noted above, it is not 

necessarily inconsistent that Richardson has both periodontitis and gingivitis.) Thus, 

absent further information, the Court believes Richardson can represent Class IIC. 

* * * 

In sum, Plaintiffs have persuaded the Court at this stage of the litigation that 

a substantial number of prisoners with early, moderate, or advanced periodontitis do 

not receive scaling and root planing and the associated follow-up care. So the Court 

has created Class IIC to allow these prisoners to pursue class-wide relief. 

Plaintiffs also ask the Court to make Richardson a representative of formerly 

defined Class IIB. This request is moot in light of the Court deeming Richardson a 

representative of redefined Class IIB and new Class IIC. 

For the foregoing reasons, Plaintiffs’ motion for partial relief from the Court’s 

certification order (ECF No. 302) is GRANTED IN PART and DENIED IN PART. 

Below is an updated chart summarizing the certified classes. The parties should note 

the Court’s articulation of the legal claims of Class IIA, Class IIB, and Class IIC. 

SO ORDERED.
