Management of a Type III Dens Invaginatus using a Combination Surgical and Non-surgical Endodontic Therapy: A Case Report
Authors: Hegde Mithra N. , Shetty Aditya , Sagar Rekha 
Published: July 2019

Abstract

Aim
The aim of this report is to present a case of Type III dens invaginatus in a maxillary lateral incisor with a periapical lesion and its successful treatment using a combination of surgical and non-surgical therapy.

Background
The morphology of the root canal system is unique for individual teeth. A precise understanding of the morphology is very important for a successful root canal treatment. Dens invaginatus is a rare dental anomaly that can give rise to many complex anatomical forms. The complete removal of the diseased pulp tissue can be a challenge for clinicians due to the complexity of internal canal anatomy and may require either non-surgical endodontic therapy alone or that therapy may have to be combined with surgical endodontics to achieve an adequate sealing of the root canal system.

Case Report
A 22-year-old male presented for evaluation of a recurrent painless sinus tract in the attached gingiva adjacent to the maxillary right lateral incisor. The tooth responded negatively to vitality tests while the right central incisor responded normally. Clinically an anatomical malformation in the crown was detected in the form of an abnormal bulbous contour of the tooth in the palatal region above the cingulum. Radiograph evaluation confirmed the presence of dens invaginatus and a periapical radiolucent lesion. The patient received combined nonsurgical and surgical endodontic therapy to achieve a favorable outcome.

Summary
Complications presented by Type III dens invaginatus and acute periapical abscess necessitated the use of combined non-surgical and surgical endodontic therapy to attain a favorable seal of the root canal. The prognosis at a six-month post-treatment evaluation appeared to be good.

Clinical Significance
Dens invaginatus requires an early diagnosis and treatment. It may result in radicular and periapical pathosis requiring a combined non-surgical and surgical endodontic approach to treatment.

Serum Immunoglobulin Levels in Type 2 Diabetes Patients with Chronic Periodontitis
Authors: Awartani Fatin 
Published: July 2019

AbstractAimThe association between diabetes and periodontal disease has been well documented. Periodontitis is associated with alterations in immune responses in both diabetic and nondiabetic subjects. While diabetes is considered to be a risk factor for periodontal disease progression, few studies have demonstrated an association between the level of glycemic control and periodontal disease. Although poor glycemic control is significantly associated with poor periodontal health, few studies have been performed in Saudi Arabia to evaluate the immune responses in poor and better glycemic control and its effect on periodontal tissue. The aim of this study is to assess serum immunoglobulin levels (IgA, IgG, IgM) in type 2 diabetic (poor control and better control) and nondiabetic subjects with chronic periodontitis.Methods and MaterialsA total of 105 female patients were included in the study and they were divided into three groups, with 35 patients in each group. Group 1 was comprised of cases of diabetes exhibiting better control (HbA1c≤9%) and Group 2 was comprised of cases of diabetes exhibiting poorer control (HbA1c>9%). The third group was comprised of nondiabetic subjects with chronic periodontitis. In this study, clinical examination included plaque index, bleeding on probing, probing pocket depth, and attachment level (measured in all three groups). Serum immunoglobulin (IgA, IgG, IgM) levels were estimated and compared to the levels estimated for diabetic controls.ResultsMean plaque index, bleeding index, and probing pocket depth showed no significant differences among the three groups. However, mean clinical attachment loss was significantly higher for Group 2 as compared to Groups 1 and 3. IgA and IgG levels were found to be significantly higher in Group 2 (poorly controlled diabetes) as compared to Group 1 (better control) and Group 3 (control group).There is a positive correlation between CAL and IgA and IgG, whereas there is a negative correlation between CAL and IgM.ConclusionThe present study indicates that poor glycemic control may be associated with the increase in IgA and IgG serum antibodies. Elevated antibody levels may explain why poorly controlled diabetes exacerbates periodontal disease.Clinical SignificanceThese findings demonstrate the importance of the immune system as well as good glycemic control, especially in patients diagnosed with periodontitis. The changes observed in immune response may be the cause or the effect of periodontal disease in diabetic patients. The increased incidence of periodontitis in diabetic patients suggests that the alteration in immune response may contribute to the pathogenesis of periodontitis in patients with poorly controlled diabetes.CitationAwartani F.

Published: July 2019

Abstract
The purpose of this pilot study was to evaluate the effects of an effervescent sodium bicarbonate based oral composition on plaque and gingivitis. Subjects selected for this study presented at screening with moderate plaque and American Academy of Periodontology (AAP) Type I/II periodontal status. At baseline, subjects were allocated to one of two groups by simple randomization; placebo (n=16) and active (n=16). During the study two subjects withdrew due to non-compliance and one because of a death in the family. Data were collected at baseline, day 14, and day 28. The Plaque Index (PI) of Silness and Loe was used to quantify the amount of supragingival plaque surrounding six selected teeth (3, 14, 8, 19, 24, 30), and the Gingival Index (GI) of Loe and Silness was used to assess bleeding tendencies and visual appearance on the same six teeth. A soft tissue oral assessment was completed at each visit. Subjects were asked to perform study treatment three times a day, after meals, and continue with normal oral hygiene procedures. Subjects were requested to complete a 28-day diary to assess compliance. Data were analyzed using repeated measures analysis of variance. There were no statistically significant differences between the placebo and the active product groups and no statistical significant interaction between product and location within the mouth or visit for either the plaque or gingival scores. Results reveal the product was safe to oral tissues and was well accepted by subjects.
Pathologic Status and Changes in Mandibular Third Molar Position During Orthodontic Treatment
Authors: Güngörmüş Metin 
Published: July 2019

Abstract

Purpose
The purpose of this study was to evaluate the changes in mandibular third molar (M3) position and pathologic status associated with M3 in the cases orthodontically treated.

Materials and Methods
This study was carried out on a total of 76 subjects, 42 males and 34 females ranging in age from 18 to 23 years. Thirty of them were treated without extractions (non-extraction group), 26 were treated with the extraction of four first premolars (extraction group), and 20 did not receive orthodontic treatment (control group). Positional changes of third molars and pathologic status associated with M3s in the cases treated orthodontically were evaluated radiographically and clinically. Data were analyzed with parametric and non-parametric tests.

Results
It was clinically observed that 18% of third molars in the non-extraction group and 15% of those in the extraction group erupted in normal position; 83% of third molars in both groups erupted partially in a mesioangular position. However, it was determined that 43% of the teeth that partially erupted developed pericoronitis and 4% had dental caries. It was determined radiographically that there was insufficient space for most of the M3s to erupt in the orthodontically treated cases and the angulations of these teeth were not sufficiently improved.

Conclusions
In this study, it was determined that 83% of the M3s in orthodontically treated cases partially erupted in a mesioangular position and 43% of these teeth were associated with pericoronitis.

Mentoring: A Professional Responsibility
Authors: Haisch Mary Ann , Cromley Nora L. 
Published: July 2019

Abstract
Dental and dental hygiene students were surveyed to determine how many students had participated in high school or college career exploration courses sponsored/supported by Oregon Health & Science University (OHSU) School of Dentistry. The participants were asked to identify which aspects of the programs were the most influential in shaping their exploration of a dental or dental hygiene career and why they decided to apply to the dental or dental hygiene program. These aspects included the availability and the cost of the courses, lecture content, hands-on activities in the laboratory, observations in dental offices, mentoring activities of dentists, dental hygienists, dental/dental hygiene students, and perceived value for applicant competitiveness. The faculty evaluated their level of participation in relation to teaching responsibilities and time commitment. An analysis of the direct and indirect costs to the school was examined. Results of the surveys indicated that between 20-42% of the entering classes had participated in one or more career exploration activities or programs. Participants identified mentoring relationships with their current dentist and dental hygienist as the most important factor in determining their decision to choose dentistry or dental hygiene as a career. Observations in dental offices, encouragement from a dental and/or dental hygiene student, hands-on activities, and repetitive positive career experiences were also significant factors.

Effects of a Betaine-containing Toothpaste on Subjective Symptoms of Dry Mouth: A Randomized Clinical Trial
Authors: Rantanen Irma , Tenovuo Jorma , Pienihäkkinen Kaisu , Söderling Eva 
Published: July 2019

AbstractOur aim was to study the effects of mildly flavoured sodium lauryl sulphate (SLS)-containing and detergent-free toothpastes with and without betaine (BET) on subjective symptoms of dry mouth in a randomised clinical trial. BET is an osmoprotectant that reacts with molecules to supply the surface with a water coating that protects cells from surfactants. Twenty-seven xerostomic patients and 18 healthy controls took part in the randomised, double-blind clinical trial with a crossover design. Three mildly flavoured toothpastes: (1) 4% BET, (2) 1% SLS and 4% BET, and (3) 1% SLS were used for six weeks each. The reference or washout paste contained neither SLS nor BET. The subjects’ dental appointments were at the beginning of the trial and before and after the use of each toothpaste. At each appointment, the subjects were interviewed about subjective sensations of dry mouth (Visual Assessment Scoring (VAS) Index). The subjects did not report any adverse effects in connection with the use of the toothpastes. The VAS scores for lip dryness and eating difficulties were significantly lower for the BET paste (lip dryness: BET<BET+SLS; p < 0.005 and eating difficulties: BET<BET+SLS; p = 0.02; BET<reference; p = 0.003). The BET paste relieved dry mouth symptoms in 44% of the xerostomic patients, the corresponding figures for the other pastes being BET+SLS 22% (p = 0.002 as compared with BET), SLS 18% (p = 0.022), and reference 7% (p = 0.000). In conclusion, all the mildly flavoured toothpastes used in this study were well accepted by the xerostomic subjects. Thus, other toothpaste components may be more mucosa-irritating than just SLS, or else they enhance the effect of SLS. The detergent-free, BET-containing toothpaste appeared to be associated with relief of some symptoms of dry mouth.CitationRantanen I, Tenovuo J, Pienihäkkinen K, et. al.

Benign Fibrous Histiocytoma: Report of Case
Authors: Ertaş Ümit , Büyükkurt M. Cemil , Çiçek Yasin 
Published: July 2019

Abstract
Benign fibrous histiocytoma is a rare and usually painless oral neoplasm found in adults that may affect either soft tissue or bone typically noted in their fifth decade. This case was found in a 32 year-old Caucasian male who presented with a fairly well circumscribed unilocular radiolucent lesion extending from the mandibular right first incisor to the left first premolar and reaching the inferior mandible on a panoramic radiograph. A bony window was created and the intrabony lesion was curetted. Multiple sections revealed a cellular tumor composed of uniform spindle-shaped cells arranged in a prominent whorled or storiform pattern. Scattered xanthoma cells, multinucleated giant cells, lymphocytes, and deposits of hemosiderin were noted throughout the lesional stroma. Although malignant fibrous histiocytoma of the bone is relatively well known, benign fibrous histiocytoma of the bone is very rare.

Remineralization Potential of a New Toothpaste Formulation: An In-Vitro Study
Authors: Muñoz Carlos A. , Torrado Anna , Valiente Manuel , Zhang Wu , Li Yiming 
Published: July 2019

Abstract
The aim of the present study was to determine the ability of a dentifrice containing a mixture of ion-exchange resins (named NMTD), which supplies calcium, fluoride, phosphate, and zinc ions, to promote remineralization and/or inhibit demineralization of dental human enamel in a pH cycling model in vitro. A fluoride toothpaste was used as the control. The enamel specimens were tested for microhardness before and after 10 days and 16 days of the demineralizing and remineralizing treatments. The results of this study showed both dentifrices were effective in limiting in vitro enamel demineralization although the effects were not significantly different from each other. Inclusion of calcium and phosphate ion-exchange resins in the dentifrice containing a fluoride ion-exchange resin maintained a similar net outcome of the conventional dentifrice in the demineralization/ remineralization process under the experimental conditions employed.

Abstract
In this study, the effects of guided bone regeneration (GBR) on the healing of bone defects were evaluated. Resorbable membranes were placed in experimentally formed cavities in the right posterior tibia of 30 rabbits. Decalcified histological sections were evaluated using optical microscopy at 10, 20, and 30 days after GBR. Osteocondrial bone union, active bone formation and spongiosal bone formation values of the GBR group are higher than the control group. It was found that GBR technique had a positive and accelerating influence in all phases of bone healing.

Examiner Agreement in the Replacement Decision of Class I Amalgam Restorations
Authors: Ermiş R. Banu , Aydin Ulkem 
Published: July 2019

Abstract
The aim of this study was to investigate interexaminer and intraexaminer agreement in the replacement decision for Class I amalgam restorations. Three examiners evaluated the restorations clinically and with bitewing radiographs. One hundred and twelve restorations were evaluated for secondary caries, body fracture, deficient anatomic form (contour), ditched margins, and marginal overhangs. After one month, the assessments were repeated by the same examiners under the same conditions. Cohen's Kappa analysis was used to analyze the data. The number of replacement decisions varied from 12 to 27 and from 6 to 14 at the first and second evaluations, respectively. The Kappa statistics indicated “moderate” to “substantial” consistency for interexaminer and intraexaminer agreement in the replacement decisions based on clinical and radiographical examinations. Restorations with deficient anatomic form and marginal overhangs presented the most frequent diagnostic difficulties and lead to disagreement among examiners. The most frequently mentioned reasons for replacement were the restorations had ditched margins at both clinical evaluation periods and secondary caries was detected during radiographical evaluations. In the absence of agreement among examiners, clinical and radiographic guidelines are necessary for replacing Class I amalgam restorations.

The Effects of Different Application Techniques and Orifices on the Amount of Dentifrice Dispensed
Authors: Ölmez Ayşegül , Tüfekcioğlu Dilek , Erdemli Elgin 
Published: July 2019

Abstract

Purpose
The purpose of this study was to evaluate three different methods (ST: Standard technique; PS: Pea-size; TT: Transverse technique) for dentifrice use in children between 5-7 years of age, as well as to compare the amount of dentifrice dispensed by using tubes with different orifices (cresent or round shaped).

Methods and Materials
One hundred children who dispensed the dentifrice themselves were asked to apply the quantity of dentifrice they usually used (ST or TT) (Phase-I). In Phase-II they were instructed to apply a PS amount, and in Phase III the TT was demonstrated. Statistical analysis was obtained by using Anova and t-test.

Results
Most of the children (82 patients) preferred to use the ST rather than the TT (18 patients). A decrease in the dentifrice amount was obtained with both of the shaped orifices after the instruction of PS or demonstration of the TT (p< 0.05). It was observed the amount of dentifrice dispended decreased when a cresent-shaped orifice was used.

Conclusion
Children usually preferred to use the ST rather than the TT before the instruction or demonstration by the operator. The amount of dentifrice dispensed generally decreased when a dentifrice tube with a crescentshaped orifice was used.

Modified Approach to the Bio-Col Ridge Preservation Technique: A Case Report
Authors: Fowler Edward B. , Whicker Robert 
Published: July 2019

Abstract
With today's esthetic conscious population, the day of simply extracting a tooth and replacing it at a later date is unacceptable to many patients. It is vital to preserve and maintain the edentulous ridge and normal gingival architecture, which often collapses after tooth extraction. As clinicians, we must have multiple techniques available to preserve or restore the function and esthetics when teeth are unrestorable. This case report describes a modified approach to the “Bio-Col Technique.” This modification simplifies the procedure without compromising the esthetic result.
