Introduction The esoteric Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) infection or COVID-19 has been an unusual plummet in dental/orthodontic practice. Based on current recommendations for various amendments in an orthodontic practice, this scoping review aims to identify orthodontic appliances that are most appropriate to us during this on-going pandemic. Methods Electronic databases (PubMed, Scopus, Web of Science, Science Direct, and Google Scholar) were searched up until August 11, 2020. Full-text articles in English with keywords “COVID-19 and Orthodontics” and related search terms were included. Results Out of 17 retracted articles, only 4 articles were found to be brief the choice for orthodontic appliances in pandemic times speculating clear aligner therapy (CAT) to be a pragmatic solution. The remaining articles were also thoroughly studied and the new norms set by the pandemic were determined. Criteria for orthodontic appliance selection included careful patient screening and collection of records, minimal physical visits, efficient use of technology, virtual consultations but the use of PPE for physical appointments; and lesser AGPs with a lesser risk of airborne transmission. Conclusions Subject to regional demands, CAT can be considered as the relatively safer modality-predictable and effective apposite to fixed orthodontic appliances in these unprecedented times.

Aim The aim of periodontal surgery is complete regeneration. The present study was designed to evaluate and compare clinically soft tissue changes in form of probing pocket depth, gingival shrinkage, attachment level and hard tissue changes in form of horizontal and vertical bone level using resorbable membranes. Materials and methods Twelve subjects with bilateral class 2 furcation defects were selected. After initial phase one treatment, open debridement was performed in control site while freezedried dura mater allograft was used in experimental site. Soft and hard tissue parameters were registered intrasurgically. Nine months reentry ensured better understanding and evaluation of the final outcome of the study. Results Guided tissue regeneration is a predictable treatment modality for class 2 furcation defect. There was statistically significant reduction in pocket depth as compared to control (p < 0.01). There is statistically significant increase in periodontal attachment level within control and experimental sites showed better results (p < 0.01). For hard tissue parameter, significant defect fill resulted in experimental group, while in control group, less significant defect fill was found in horizontal direction and nonsignificant defect fill was found in vertical direction. Conclusion The results showed statistically significant improvement in soft and hard tissue parameters and less gingival shrinkage in experimental sites compared to control site. Clinical significance The use of FDDMA in furcation defects helps us to achieve predictable results. This cross-linked collagen membrane has better handling properties and ease of procurement as well as economic viability making it a logical material to be used in regenerative surgeries.

Introduction: This study aimed to test the reliability of the index of treatment need by newly trained orthodontic residents. Materials and Methods: A total of 100 patients were assessed by the panel of four consultant orthodontists using the index of orthodontic treatment need (IOTN) index, and the agreed category was set as the 'gold standard'. Four residents of the department in the initial stages of formal orthodontic training and lacking the knowledge of using the IOTN index were trained to score the treatment need according to the IOTN index. All four residents were then asked to score the 100 sets of models using both the indexes of IOTN. Results: Kappa scores for inter-rater agreement with the expert panel for the major categories (1–4) demonstrated moderate agreement (kappa: 0.59–0.5623) for all raters. The percentage agreement ranged from 84.03% to 88.10% in all cases. Intra-rater agreement for the major categories was fair to moderate (kappa: 0.53–0.80). Conclusions: The IOTN index is a reliable index to be used for determining the priority of treatment needs in orthodontic treatment. The clarity and simplicity make the index easy to learn and apply with minimal training. The simplicity of the IOTN index makes it easy to learn and apply by novices.
