European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 10, Pages 198-209

Objective: To evaluate the anatomical variations in bicortical thickness of the mid palatine region in order to calibrate the maximum depth of micro osteoperforation permissible at various sites along the midpalate.
Design: This was a retrospective cone-beam computed tomography study
Setting: The study was conducted in Department of Orthodontics and Dentofacial Orthopedics
Methods: CBCT images of 60 subjects between the age of 14-28 years were taken up for evaluation from the records of the dental hospital. The sixty scans were from 37 males and 23 females. The CBCT images of subjects were evaluated by two investigators to assess the bicortical thickness of bone in the midpalatal region using fixed reference points and planes. Mean and standard deviation of bicortical thickness at various fixed landmarks were calculated. One-way ANOVA was done to check for variation of bicortical thickness among various sites in males and females. Intra operator reliability was checked by the paired T- test and Kappa statistics were used to evaluate inter-operator reliability between the observations by two observers (A.M, H.B).
Results: A mean value of 8.93+/-1.67mm, 6.37+/-1.56mm, 4.42+/-1.40mm, 3.11+/-1.21mm, 2.47+/-0.95mm, 2.07+/-0.93mm was obtained for reference points A, B, C, D, E and F respectively in males. It was observed that a mean value of 7.93+/-1.56mm, 5.48+/-1.39mm, 3.66+/-1.01mm, 2.81+/-1.06mm, 2.35+/-1.08mm, 2.09+/-1.18 mm was obtained for points A, B, C, D, Eand Frespectively in females. Statistically significant difference was observed between the six points (ANOVA test; p value- 0.00). The Intra operator reliability was assessed using a paired T-test and was estimated to be 0.93 and the inter-operator reliability by Kappa statistics was 0.321.
Conclusion: The bicortical thickness of the mid palate varies showing more thickness anteriorly and progressively getting thinner posteriorly. The anterior segment showed more variations in the thickness compared to the posteriors. Micro osteoperforation of palate can be done upto a depth of 8.93 mm in males and 7.93mm in females and a minimum depth of 3.11 mm in males and 3.66mm in females is possible in the anterior half of the palate.

Prediction planning for orthognathic surgery allows the orthodontist to anticipate changes in hard and soft tissue that may arise as a result of the surgery. This can be useful to accordingly plan the orthognathic surgery and also as a means for informed patient’s consent and to communicate with the concerned maxillofacial surgeon. Cephalometric prediction in orthognathic surgery enables direct evaluation of both dental and skeletal movements, and can be performed manually or by computers, using several software programmes currently available. They can also be incorporated with video images. The aim of this article is to present and discuss the different methods of cephalometric prediction of the orthognathic surgical outcome.

Anterior open bite is one of the most difficult malocclusions to treat with its varied characterizations. Appropriate etiology should be identified for effective management of open bite. Anterior Open Bite can irrespectively occur in all kinds of malocclusion. Aesthetics, speech, mastication and tooth wear are some of the common concerns for the patients. Thorough apprehension of the anomaly is important in determining the appropriate corrective measures. This review will throw more light on the etiology of open bite, diagnosis and treatment enabling the clinicians for better understanding of the malocclusion.

Temporomandibular disorders are considered as the main source of pain in the head and neck region which is of non- dental in origin. Its etiology is multifactorial and its pathogenesis has not been completely understood. The interest in the relationship between occlusal factors, orthodontic treatment and TMD has increased over the years. Hence the aim of this article is to review ten association of TMD and orthodontics from the available literature.

Most of the signs of ageing can be related to volume loss. Dermal fillers are substances which can be injected beneath the skin, that helps restore the lost volume. They are gel like in consistency.1 Patients seeking orthodontic therapy often also present with adjuvant soft tissue deformities. The soft tissue deformity caused by an underlying skeletal or dental deformity will be self-corrected by orthognathic and/or orthodontic treatment. The inherent soft tissue deformities like decreased lip length, increased or decreased lip thickness, inadequate vermillion show, can be addressed by injecting dermal fillers, Botulinum Toxin A and cosmetic surgical soft tissue procedures.

A wide range of scientific research is being carried out in the world to predict and detect early manifestations of caries in children during orthodontic treatment, as well as to optimize the effectiveness of diagnostic and treatment-and-prophylactic measures, existing diagnostic methods are already insufficient, there is an urgent need for additional research methods. From these positions, it seems promising to study diagnostic and therapeutic measures aimed at improving the quality indicators of orthodontic care for children. The development of the closest possible approach to the diagnosis and treatment of caries during orthodontic treatment in the early stages will help to obtain a stable aesthetic outcome in the treatment of orthodontic patients, and to avoid relapses. In modem orthodontic dentistry acute problem of prevention of dental caries and periodontal diseases, especially in children and adolescents who have not yet completed the process of mineralization of hard tissues: soon after teething create a situation of increased risk of tooth decay. The purpose of this paper is to analyze complex information about methods of prevention of dental caries in patients with removable and non-removable orthodontic appliances

Nanotechnology over past decades, has emerged as a mainstay in various fields and has
been employed in various biomedical applications. It is currently being extensively used in
the manufacture of drugs, as a diagnostic aid, in implants, as a prosthetic material and in
tissue engineering. With the recent introduction of advanced Nano robotic models in local
anesthetic procedures, the applications and importance of nanotechnology in the field of
healthcare have gained renewed impetus. This review primarily throws light on the
current applications of silver nanoparticles in the field of Dentistry, emphasizing on
orthodontics in particular, with regard to their antimicrobial properties, anti-cariogenic
effects, Nano silver coating applications of orthodontic brackets, micro implants,
biocompatibility analysis and fixed orthodontic appliances.

This study was designed to understand and evaluate the choice between friction and frictionless mechanics in extraction space closure. The orthodontics case sheets were evaluated to identify extraction cases. After examining 428 case sample tabulation of choice between friction and frictionless mechanics were examined. More female patients underwent orthodontic treatment. More cases were treated by friction mechanics rather than by frictionless mechanics. Only 55 cases of the whole were treated by loops for retraction and space closure. More orthodontists preferred retraction using friction mechanics which can be attributed to factors like being treated by faster mechanics, less cost and lesser demanding skill of clinician. The chair side time required is reduced
