Abstract

Background: Epidemiology of malocclusion and assessment of orthodontic treatment needs are of great importance in many countries and are included in numerous national-level surveys. The aim of orthodontic treatment is to achieve the best possible occlusion within the framework of function, stability, and esthetics. Objective: The present study aims to assess the prevalence of malocclusion and Orthodontic treatment needs of 12–15-year-old school-going childrenusing the Index of Orthodontic Treatment Need (IOTN) of Khudel Village, Madhya Pradesh, Indore. Materials and Methods: 300 school children (180 girls and 120 boys) of government schools of age group 12-15-year-old were examined. Type 3 examination method was used to record the orthodontic treatment need was using the Index of Orthodontic Treatment Needs (IOTN). Result: Result showed that only 38.6% had no need of treatment, (23.3%) were assigned grade 2 of IOTN Dental Health Component (DHC) score, (14.3%) required borderline treatment, (12.3%) of the total population required severe orthodontic treatment that is score 4. Extreme treatment is required by (11.3%) of the study population. Conclusion : There seems to be an inconsistency in the proportion of children needing orthodontic treatment on esthetic and dental health basis. It indicates a general lack of awareness among the school children about the severity of their existing malocclusion. More awareness programs and camps need to be conducted regarding spread of awareness of orthodontic treatment needs.   Keywords: Index of Orthodontic Treatment Need (IOTN), Malocclusion

Abstract

Aim & Objective: To determine the soft tissue angular photogrammetric standards in Central Indian topics. Materials and Methods: 40 central Indian participants, 20 males and 20 females, ranging in age from 18 to 25, were examined in this study using lateral profile photographs Standardized profile pictures were obtained between the focal lengths of 55 and 200 mm with a camera Canon 1500D macro lens. Result: The data were analysed using SPSS 20.0, a statistical software for social sciences. Using the Kolmogorov-Smirnov test to determine the probability distribution of the data, it was determined that the data were not normally distributed (p value.05). Conclusion: The present study used photogrammetric analysis to develop soft tissue face measures that will help orthodontists undertake more quantitative analysis and reach informed conclusions. By using this photogrammetric approach, the collected mean values may be compared to records of persons who had the same characteristics. There were statistically significant variations in Central India for a few key parameters.   Keywords: Central India, Soft Tissue, Photographic Standards

Abstract

Aim: To assess and compare anteroposterior jaw dysplasia indicators i.e. (Wits-appraisal, ANB-angle, β(Beta)-angle, W-angle, YEN-angle and ?(Pi)-angle) in Angle's Class I molar relation subjects with normal overjet of central India. Materials and Methods: Sum of 40 lateral cephalograms were traced in line with the inclusion criteria of Angle’s Class I molar relation subjects. Subjects had to be between the ages of 18 and 30 and have a normal overjet and aligned arches. We measured and compared the Wits-appraisal, ANB-angle, (Beta)-angle, W-angle, YEN-angle and Pi-angle. The statistical package for social sciences (SPSS) 20.0 version was used to examine the data. We used descriptive statistics. The Spearman's correlation coefficient was used to evaluate the correlation between the variables. Statistics were judged as significant at a p-value of 0.05. 95% of the confidence interval was chosen. Results: The result showed descriptive statistical representation for the norms of Wits-appraisal, ANB-angle, Beta-angle, Yen-angle, W-angle, and Pi-angle for the Central India population. We found a high correlation of ANB-angle with YEN-angle, ANB-angle and Pi linear, ANB-angle and W-angle, Beta-angle and W-angle, YEN-angle and W-angle and Pi-angle and Pi linear. Conclusion: Among the angles used for the comparative evaluation for the prediction of anteroposterior jaw dysplasia, W-angle and YEN-angle had the utmost accuracy, whereas Beta-angle had the least. Therefore, YEN-angle and W-angle are reliable in our practice in the prediction of anteroposterior jaw dysplasia in the Central India population.   Keywords: Anteroposterior jaw dysplasia, Class I molar relation, ANB­angle, Wits appraisal, Beta­angle, Pi­ angle, W­angle, Yen­angle

Abstract

Extra oral appliances have been used since ages to bring about dental changes, skeletal changes and for anchorage reinforcement. Growth modifications can be done with help of these appliances. This can be done by inhibiting the growth or redirection of the growth. The biomechanics of the extraoral appliances needs to be understood well for using these appliances. The topic of headgear is vast and the following article tries to cover the details regarding the same in brief. The location of centre of resistance for application of force is important and plays a significant role in biomechanics and outcome of treatment results. Various types of headgears and their use depending on different criterias are discussed in detail.   Keywords: Headgear, Kloehn headgear, Facebow, Extraoral anchorage, Centre of resistance
