Introduction: The American Board of Orthodontics objectively quantifies the complexity of malocclusion before orthodontic treatment. This study aims to assess the complexity of cases as measured by ABO discrepancy index (DI) in the patients under treatment by the orthodontics residents of Kantipur Dental College (KDC). Additional objectives were to 1) Ascertain DI relative to sex, age and race/ethnicity, and 2) Differential analysis of the components of the DI. Materials & Method: DI was determined for 220 consecutive cases started by orthodontic residents of KDC in a three-year graduate orthodontics program from 2014-2018. The DI was scored and compared with the patient’s sex and age. Result: The DI is not statistically significant to age, sex and race/ ethnicity. The mean DI score (± SD) was 18.65 (±10.521). Differential analysis of the components of the DI showed that the highest scores were for cephalometric measures, followed by overjet, crowding, occlusion, and the lowest scores were for lingual posterior crossbite. Conclusion: The DI was a relatively reliable index for measuring malocclusion severity. It is independent of patient’s age and race/ethnicity but is dependent on sex. Area of possible future improvements includes malocclusion sub-categories (Class II div. 1 and 2), and scores for bony and soft tissue impactions.

Background Orthodontic treatment is a common health care intervention; treatment duration can be lengthy (2-3 years on average), and adherence to treatment advice is therefore essential for successful outcomes. It has been reported that up to 43% of patients fail to complete treatment, and there are currently no useful predictors of noncompletion. Given that the National Health Service England annual expenditure on primary-care orthodontic treatment is in excess of £200 million (US $267 million), noncompletion of treatment represents a significant inefficient use of public resources. Improving adherence to treatment is therefore essential. This necessitates behavior change, and interventions that improve adherence and are designed to elicit behavioral change must address an individual’s capability, opportunity, and motivation. Mobile phones are potentially an invaluable tool in this regard, as they are readily available and can be used in a number of ways to address an individual’s capability, opportunity, and motivation. Objective This study will assess the effectiveness and acceptability of a personalized mobile phone app in improving adherence to orthodontic treatment advice by way of a randomized controlled trial. Methods This study will be conducted in 2 phases at the Eastman Dental Hospital, University College London Hospitals Foundation Trust. Phase 1 is feasibility testing of the My Braces app. Participants will be asked to complete the user version of the Mobile Application Rating Scale. The app will be amended following analysis of the responses, if appropriate. Phase 2 is a randomized controlled trial to test the effectiveness and acceptability of the My Braces app. Results This study was approved by the London – Bloomsbury Research Ethics Committee on November 5, 2019 (reference 19/LO/1555). No patients have been recruited to date. The anticipated start date for recruitment to phase 1 is October 2020. Conclusions Given the availability, affordability, and versatility of mobile phones, it is proposed that they will aid in improving adherence to treatment advice and hence improve treatment completion rates. If effective, the applicability of this methodology to developing behavior change/modification interventions and improving adherence to treatment across health care provides an exciting opportunity.

A quantitative assessment of the true dental practitioner contribution to orthodontic care in Scottish Health Board areas during the period 1966–1975, shows that the amount of orthodontic treatment given by general dental practitioners in Scotland has diminished in the 10 year period studied. A wide variation was observed in respect of the mean number of orthodontic treatments per year per practitioner, and there was also a lack of uniformity in the proportion of practitioners providing an orthodontic service relative to the different area health boards. The findings have also shown that between 1966–1975, a considerable reduction has occurred in the mean number of practitioner orthodontic treatments commenced each year in the Greater Glasgow and Lothian Health Board areas. The evidence of this study also suggests that orthodontics should become recognized as a postgraduate dental specialty and that it would be appropriate to introduce specialist registration as a means of improving the quality and quantity of orthodontic care within the National Health Service. This should also be accompanied by certain administrative changes, as the present anomalous situation whereby specialist practitioners are permitted to practise within the general dental service should be discontinued.

Abstract Objective: To test the hypothesis that there is no difference in the accuracy of bracket placement produced by OrthoCAD iQ indirect bonding (IDB) and that of an in-house fabricated IDB system by measuring the quality of intra-arch dental alignment at the end of simulated orthodontic treatment. Materials and Methods: Twenty-eight artificial teeth were arranged to resemble a typical preorthodontic malocclusion. Forty-six sets of models were duplicated from the original malocclusion and randomly divided into two sample groups. Half of the models had their bracket positions selected by OrthoCAD, while the others were completed by a combination of faculty and residents in a university orthodontic department. Indirect bonding trays were fabricated for each sample and the brackets were transferred back to the original malocclusion following typical bonding protocol. The individual teeth were ligated on a .021 × .025-inch stainless steel archwire to simulate their posttreatment positions. The two sample groups were compared using the objective grading system (OGS) originally designed by the American Board of Orthodontics. Results: The mean total OGS score for the OrthoCAD sample group was 39.25 points, while the traditional IDB technique scored 41.00 points. No statistical difference was found between total scores or any of the four components evaluated. Similar ranges of scores were observed, with the OrthoCAD group scoring from 30 to 52 points and the traditional IDB group scoring from 33 to 53 points. Conclusions: The hypothesis is not accepted. OrthoCAD iQ does not currently offer a system that can position orthodontic brackets better or more reliably than traditional indirect bonding techniques.

Objective: To establish the association between malocclusion severity and orthodontic case complexity as assessed by the Dental Aesthetic Index (DAI) and the American Board of Orthodontics Discrepancy Index (ABO-DI), respectively. Design: Cross-sectional study. Setting: Pre-treatment dental casts and radiographs from 500 individuals (294 women and 206 men; mean age = 26.06 ± 11.58 years) were randomly selected from the orthodontics department of a private university. Methods: Malocclusion severity was assessed using DAI and case complexity was evaluated with ABO-DI. Three previously calibrated operators performed the measurements. Spearman’s correlation analysis, Mann–Whitney U test, Kruskal–Wallis test and a linear generalised model were used for statistical evaluation ( P < 0.05 was considered significant). Results: Although the correlation (r = 0.45; P < 0.0001) between malocclusion severity and case complexity was moderate, strong evidence of an association ( P < 0.001) between dichotomised DAI and ABO-DI total scores was observed. The linear generalised model showed that for each point of increase in DAI score, the ABO-DI score increased an average of 0.3624 points ( P < 0.0001). Conclusion: An association between malocclusion severity and case complexity is suggested. A linear generalised model could be used to predict the complexity of the case from the malocclusion severity (DAI score).

AbstractObjective:To perform a blind comparative evaluation of the quality of orthodontic treatment provided by orthodontists and general dentists.Materials and Methods:Sixty cases of orthodontic treatment were evaluated—30 treated by specialists in orthodontics and 30 treated by general dentists with no specialization course. Orthodontists were selected randomly by lots, in a population of 1596 professionals, and recordings were performed based on the guideline established by the Objective Grading System proposed by the American Board of Orthodontics. Each participant was asked to present a case considered representative of the best outcome among the cases treated, regardless of the type or initial severity of the malocclusion. Statistical analysis involved the chi-square, Wilcoxon, and Mann-Whitney tests. The level of significance was set at P  =  .05 for the statistical tests.Results:The results showed that 29 orthodontists (96.7%) presented cases considered satisfactory and would be approved on the qualification exam, whereas only 15 dentists (50%) had cases considered satisfactory. Moreover, treatment time was significantly shorter among the orthodontists (P  =  .022), and the posttreatment comparison revealed that orthodontists achieved better outcomes considering all the variables studied.Conclusions:Orthodontists spend less time on treatment and achieve better quality outcomes than cases treated by general dentists who have not undergone a specialization course in orthodontics.
