Comparison of Effectiveness of Two Designs of Interdental Toothbrushes in removing Dental Plaque
Authors: Jayasinghe Vajira P , Tilakaratne A , Perera Kathya L 
Published: June 2017

ABSTRACT

Aim
To compare the plaque removal ability of two designs of interdental toothbrushes (IDTBs) [“tube-like” IDTB = TT and “conical” IDTB = CT] in the posterior part of the mouth in adult patients.

Materials and methods
The study sample consisted of 107 adult patients who were in the periodontal maintenance phase having completed treatment for “chronic mild–moderate gingivitis.” Each selected patient was subjected to plaque scoring in the posterior sextants. Four sites per tooth were scored after plaque disclosing. The percentage of plaque was calculated. One of the two designs of IDTBs (TT or CT) was randomly assigned for each patient. They were instructed to carry out eight strokes back-and-forth in the relevant interdental spaces, following demonstration of the technique on a model. The interdental surfaces were reexamined for remaining plaque, and the plaque score was taken. The percentage of reduction of plaque after using the IDTB was calculated.

Results
The mean interdental plaque score for the “TT design” group (n = 56) was 82% initially, whereas the same for “CT design” group (n = 51) was 78%, and this difference was not significant statistically. Following use of TT design, the plaque score in this group was reduced to 24%, which is a 71% reduction from the initial plaque score. This reduction was significant statistically (p < 0.004; t-test). The CT design also showed a dramatic reduction (79%) in plaque score following use of this design (p < 0.007; t-test).

Conclusion
Although both designs (CT and TT) were highly effective in posterior interdental spaces, the CT design appeared to be better than TT design in controlling interdental plaque.

Effects of Silane on the Push-out Bond Strength of Fiber-reinforced Resin Posts luted with different Self-adhesive Resin Cements
Authors: Radnai Marta , Rajnics Zsolt , Marada Gyula , Moetaz El-Hag 
Published: June 2017

ABSTRACT

Aim
The present study was completed to evaluate the effect of silane on the push-out bond strength on fiber-reinforced posts. The intention of the study was also to determine if there was a regional relation between the adhesive system and the push-out bond strength of the fiber post.

Materials and methods
Fifteen single rooted human teeth were endodontically treated and 2 mm diameter glass fiber-reinforced composite posts were cemented in the root canal. In the first group Futurabond DC without silane, in the second group the same luting material after silane treatment of the posts, and in the third group Clearfil DC Core System without silane were used to lute the posts.
After complete setting of the luting agents three 2-mm-thick slices were obtained from the cervical, middle, and apical regions of the roots. The specimens were subjected to push-out test in special equipment. Bond strength data were analyzed with analysis of variance tests.

Results
The Rebilda posts cemented with Futurabond DC without silane had the highest push-out bond strength at the coronal region (164.71 N ± 72.12), while the posts cemented with Clearfil without silane had the lowest value at the apical region (94.86 N ± 34.14). Silane had no significance on the push-out bond strength (p = 0.909); however, the root canal dentin regions had a significant effect (p < 0.010).

Conclusion
This study did not show any significant differences among different luting protocols. The bond strength was significantly higher in the coronal region due to the greater cemented surface area and the difference in dentin structure.

Clinical significance
Based on the results of the push-out tests, the retention of the posts did not depend on the luting methods; however, the region of the root canal played a significant role.

A Modified Three-piece Base Arch for en masse Retraction and Intrusion in a Class II Division 1 Subdivision Case
Authors: Lekhadia Dhaval Ranjitbhai , Hegde Gautham 
Published: June 2017

ABSTRACT
This case report describes the orthodontic and orthopedic treatment of an 18-year-old male patient who presented with prognathic maxilla, deep bite, low mandibular plane angle, and proclined incisors. Modified three-piece base arch was used for the intrusion and retraction of maxillary incisor. En masse retraction was achieved in 6 months. Reduced time for retraction was attributed to a single stage of retraction unlike Burstone three-piece intrusion base arch where canines are individually retracted followed by retraction of incisors. A modified utility arch was used in lower arch followed by a continuous archwire technique. The case was finished using bite settling elastics on a continuous archwire. The step between canine and premolar was corrected in the finishing phase of treatment. The final treatment outcomes were satisfactory and true intrusion was achieved with proper selection of biomechanics.

Efficiency of Mandibular Advancement Device and Bilevel Positive Airway Pressure Treatment for Severe Obstructive Sleep Apnea
Authors: Keyf Filiz , Firat Selma , Ciftci Bulent 
Published: June 2017

ABSTRACT
Recently, attention to oral appliance therapy, as mandibular advancement device (MAD), has increased. Mandibular advancement device is a popular alternative treatment, particularly for mild to moderate obstructive sleep apnea (OSA). Oral appliances for treating severe OSA are recommended for patients who failed to comply with continuous positive airway pressure treatment. This clinical report presents the treatment outcome of oral appliance therapy and bilevel device in a 70-year-old man with severe OSA and also having respiratory disturbance index (RDI) of 62.7. Polysomnographic (PSG) evaluation was performed before and about 1 week after continuous use of the MAD and then with bilevel device. The results were compared, and RDI decreased 27.5 per hour with the custom MAD, whereas RDI decreased 3.1 per hour with bilevel device. Improved PSG parameters showed that bilevel device was efficient in treatment.

Published: June 2017

ABSTRACTObjectivesIn this article, we report two cases of type I dentin dysplasia (DD): the first case is subtype “d” DD and second case is severe form of DD type I, which presents all of four subtypes and describes characteristics and the management of this type of teeth anomalies.Materials and methodsDentin dysplasia is a rare abnormality of dentin that involves both primary and permanent dentition. The normal shape of crown, short roots or its total absence, pulp chamber obliteration, crescent-shaped pulp, pulp stone, and periapical radiolucencies are the characteristics of DD type I.ConclusionThere are many problems in the management of a patient with DD. Depending on root development and pulp canal situation, endodontic treatment and tooth extraction are applied in teeth with pulp necrosis and periapical abscess. The prognosis of DD largely depends upon the age at which the diagnosis is made, and the quality of the treatment provided.How to cite this articleElmi R Z, Azimi S, Jafari S, Farzanegan A.

Published: June 2017

ABSTRACT

Aim
This article aimed to report the case of a complex odontoma interfering with tooth eruption.

Background
A common local factor causing tooth impaction or interfering with eruption of teeth is odontoma.

Case report
This case report represented a case of complex odontoma in a girl child overlying the crown of first permanent molar, which involved dental follicle and seemed to be interfering with tooth eruption. Surgical removal was done and follow-up was scheduled to control tooth eruption.

Conclusion
Odontoma as a local factor potentially interfering with tooth eruption can be resolved if it is detected early.

Clinical significance
A routine radiographic survey with panoramic images in mixed dentition period and clinical oral examination would be useful to early detection of tooth eruption problems.

Published: June 2017

Background This study presents the long-term results of the Cementless Spotorno (CLS) total hip arthroplasty system and an analysis of factors associated with clinical and radiographic outcome. Methods We studied a series of 120 consecutive CLS arthroplasties in a young patient group (mean age at surgery: 55.9 ± 5.9 years). The Merle d'Aubigné-Postel score, polyethylene (PE) wear, and radiographic status were recorded during follow-up. Survival analyses, repeated-measures analysis of variance, and a nested case-control study were used for statistical evaluation. Results After a mean follow-up of 14.6 years (range 0.1-24.2 years, including revisions and lost to follow-up), 24 revisions had been performed, 16 of which for aseptic cup loosening. Kaplan-Meier survival analysis showed a 24-year survival of 72.8% (95% CI, 63.0%-82.6%) with revision for any reason as endpoint, and 80.1% (95% CI, 70.9%-89.3%) for revision for aseptic cup loosening. Mean final Merle d'Aubigné-Postel score was 16.1 points (range 7-18). Mean PE wear at final follow-up was 2.3 mm (range 0.6-6.8 mm). A higher rate of PE wear was associated with better clinical scores but also with revision for cup loosening. Factors associated with more PE wear were: younger age at surgery; 32 - mm head; longer follow-up; and steeper inclination angle. Conclusions Beyond 10 years, the CLS stem is reliable, but the high revision rate for aseptic cup loosening is concerning, specifically with better performing (cementless) alternatives available.

Introduction Gait analysis is one of the poorly understood dimensions of the functional results obtained after periacetabular osteotomy (PAO) due to dysplasia of the hip. Materials and methods Spatiotemporal parameters as well as coronal and sagittal plane kinematics and moments were compared among three demographically similar groups of subjects: (i) 23 patients with excellent results according to the Harris Hip Score (HHS) (mean 6.6 years of follow-up); (ii) 12 patients with good and fair results according to the HHS (mean 9.3 years of follow-up); and (iii) 35 asymptomatic controls. Results 50% of the analysed sagittal plane kinematic parameters were significantly better (p<0.05) in the control group not only for the hip joint but also for the ipsilateral knee and ipsilateral ankle. A vast majority of the other evaluated gait parameters resulted similar among the groups (p>0.05). Conclusions In our experience, most of the gait parameters after PAO are close to those observed in control subjects; however, the obtained pattern cannot be classified as a completely normal gait. The excellence in terms of functional results seems not to be determined by the achievement of this theoretical goal.

Published: June 2017

Background Newer generation cable-plate designs are commonly used for periprosthetic proximal femur fractures; however, comparisons relative to cable-grips remain limited. The aim of this study was to compare radiographic healing rates of cable-plate versus cable-grip fixation for periprosthetic proximal femur fractures. Patients and methods Consecutive patients with an acute or chronic Vancouver A, B1, or B2 periprosthetic proximal femur fracture undergoing trochanteric fixation with a cable-plate (n = 46 cases) or cable-grip (n = 24 cases) system were identified retrospectively from a single-centre hospital database (mean follow-up 28 months [range 6-89 months]). Demographics, radiographic fracture healing, and complications were compared between the 2 groups. Radiographic union rates were not different between the cable-grip versus cable-plate group (67% vs. 76% respectively; p = 0.4). Healing rates of greater trochanteric fractures alone were not different between the cable-plate versus cable-grip groups (75% vs. 71% respectively; p = 0.38). The cable-plates were used for a more diverse range of fracture patterns relative to the cable-grips. Results An increased number of cables was associated with radiographic healing (odds ratio 14 [95% confidence interval 2-64]; p = 0.01), and body mass index had a negative correlation with radiographic healing (odds ratio −0.4 [95% confidence interval 0.5-0.9]. Conclusions Similar rates of periprosthetic fracture healing were seen using a cable-grip versus cable-plate system; however, the cable-plate system could be used for a more diverse range of fracture patterns.

Published: June 2017

Background Post-traumatic arthritis of the hip is a degenerative condition that commonly affects young patients. In this study, we evaluate long-term implant survival and patient-reported outcomes after primary total hip arthroplasty (THA) in patients aged 35 or younger with post-traumatic arthritis of the hip. Methods We conducted a retrospective study with follow-up. A chart review was performed to identify young patients with post-traumatic arthritis of the hip treated with primary THA. Follow-up surveys were conducted to determine implant survival and patient-reported outcomes. Implant survival was assessed using Kaplan-Meier survival analysis, and patient outcomes were determined using the hip disability and osteoarthritis outcome score (HOOS). Results We studied 42 patient s (44 THAs) with a mean time to follow-up of 14 years. The 10-year implant survival rate was 87% and 20-year implant survival rate was 41%. Implant survival did not differ based on patient age, gender, implant type, bearing surface, or use of cement for implant fixation (p>0.05). The mean HOOS scores at follow-up were 87 for pain, 85 for symptoms, 89 for ADLs, and 76 for sports. HOOS scores were significantly worse in patients that had undergone revision THA (p<0.05). Conclusions Young patients with post-traumatic arthritis of the hip have good long-term outcomes after THA. However, revision THA is predictive of worse long-term outcomes.

Published: June 2017

Objective To evaluate the viability and integrity of fresh frozen bulk femoral head allografts obtained from the institutional bone bank that were used to reconstruct severe acetabular defects and to validate the SPECT/CT method which gives both anatomical and functional data for this purpose. Methods We retrospectively reviewed 9 patients (6 female, 3 male; mean age 63.6 years). Preoperative and postoperative leg lengths, existence of the Trendelenburg sign, range of motion of the hip, visual analogue score (VAS), Harris Hip Score (HHS) and any complication were assesed at each follow-up. Radiographically, position of the cup, signs of loosening or migration, and union of the graft were all determined. At the latest follow-up, patients were evaluated with hybrid SPECT/CT. Results The average duration of follow-up was 38.1 months (24-50 months). The overall mean HHS and VAS scores were significantly improved (p<0.05). When hybrid SPECT/CT results were evaluated, the vascular phase of scintigraphy showed hyperaemia of the graft and the bone phase of scintigraphy showed normal or increased radiotracer uptake in the graft site in 7 patients. SPECT/CT images were used to determine the exact localisation of osteoblastic activity. 1 patient with minor resorption of the graft without clinical symptoms revealed mild osteoblastic activity. The patient who had no activity in the graft site was rerevised because of infection. Conclusions Institutional bank allografts are still excellent options for treating large acetabular defects in revision total hip arthroplasty where trabecular metals are not available or in common use. The Hybrid SPECT/CT method is a reliable, noninvasive method for evaluating both the integrity and viability of a bulk graft in 3-D.

Published: June 2017

Background Current studies demonstrate controversy regarding the relationship between cigarette smoking and osteonecrosis of the femoral head (ONFH). Methods We conducted a meta-analysis to evaluate the association between smoking and ONFH. Relevant articles published before September 2016 were identified by a systematic search of EMBASE and MEDLINE via Ovid. Summary odds ratios (OR) were calculated using random effects models, and study quality was assessed using a modified Newcastle-Ottawa scale. Results 102 citations were screened and 7 case-control studies were identified and included in the review. When compared with nonsmokers, current smokers had a higher risk of developing ONFH (OR 2.53; 95% confidence interval [CI] 1.68-3.79), as did former smokers (OR 1.82; 95% CI, 1.10-3.00). Within the group of current smokers, those classified as heavy smokers (with a daily number >20 cigarettes/day) demonstrated higher risks of ONFH (OR 2.03; 95% CI, 1.29-3.19), and light smokers classified as smoking <20 cigarettes/day, also demonstrated a higher risk of ONFH when compared with nonsmokers (OR 1.73; 95% CI, 1.06-2.83). When smoking was classified by pack-years, heavy smokers (>20 pack-years) were at a higher risk of ONFH (OR 2.26; 95% CI, 1.24-4.13), but no significant difference in risk was identified in light smokers (<20 pack-years) (OR 1.81; 95% CI, 0.88-3.71) when compared with nonsmokers. Conclusions Our meta-analysis showed that current smokers were at a higher risk of ONFH, this high risk can also be found in former smokers. And heavy cigarette smoking showed a higher risk of ONFH than light smoking.

For whom is restorative justice? A study on victims and (non)participation
The phenomenon of victim participation in restorative justice (RJ) has been studied from two main angles: describing victims’ motivations to take part in RJ and studying the benefits that different groups of victims may obtain when participating in RJ. However, methodological limitations of former studies have impeded to offer conclusive answers to the question ‘for whom is RJ’. This article offers insights into these issues, focusing on the descriptive findings of a mixed-method study carried out in the context of victim-offender mediation (in Spain and Belgium) and assessed before the encounter (if any) took place. Findings suggest that, before mediation, victims’ personal characteristics tend to differ. The factor ‘victim-offender relationship’ also appeared as an important variable. Implications of these findings are discussed.

Freedom of choice in restorative justice An explorative study of non-participating victims
In the field of restorative justice (RJ), relatively much is known about victims’ reasons for wanting to participate in either mediation (as part of the criminal process) or victim-offender contact (parallel to the criminal process). Much less is known, however, about why victims refuse to take part in RJ services. The current article sheds light on this issue and is based on a joint exploratory research initiative by Victim in Focus and Victim Support the Netherlands. The results indicate that participation in mediation and victim-offender contact is significantly associated with the type of offense. Victims of traffic accidents participate significantly less often in mediation than victims of other offenses. In case of victim-offender contact, victims of violent crimes participate significantly less often while victims of traffic accidents participate more often than victims of other crimes. In addition, the referrer of the case and the victim’s age are also significantly associated with participation in victim-offender contact. When a case was referred through the judicial stakeholders, victims more often did not participate, whereas when victims registered themselves, it more often led to a form of victim-offender contact. With regard to age, victims younger than 25 were significantly less often willing to participate than older victims. The specific reasons victims mention for not wanting to participate in RJ are twofold: both emotional and pragmatic reasons are mentioned. The latter were most common with regard to both mediation and victim-offender contact: victims primarily wonder ‘what’s in it for me?’ and seem to base their decision on whether to partake in RJ on its answer. Mentioning emotional reasons not to participate was in case of victim-offender contact significantly associated with judicial referrers of the case, while such reasons were less mentioned when a case was referred through victim support in The Netherlands. To further explore these associations, more research is needed.
