The newly developed regression equations are more accurate for prediction of width of unerupted permanent teeth in a Nepalese population. Further studies are required based on larger sample size, to confirm the applicability of the new regression equations proposed.

Background: The cephalometric norms derived from Caucasian population shows a great degree of variation when applied to different population. Objectives: The present research was performed with the objective of determining cephalometric norms of Brahmins of Nepal based on Jarabak’s analysis, to evaluate the variability between male and female and to compare the cephalometric norms with Caucasians. Methodology: Lateral cephalogram of 108 non-growing patients which consisted of 63 females and 45 males ofNepalese Brahmins who met our inclusion criteria were traced manually. Thirteen craniofacial parameters of Jarabak’s analysis were measured. Results: The comparison between Brahmin populations of Nepal with the Caucasian population showed statistically significant difference in ten out of thirteen parameters. The comparison between Nepalese male Brahmins and female Brahmins showed that there were statistically significant differences in eleven out of thirteen parameters. Conclusion: It can be concluded that there exists sexual and ethnic dimorphism in craniofacial features. The findings of the study highlight the fact that Brahmin population is significantly different from Caucasian population. Females presented with smaller craniofacial variable than male when gender comparison was performed among Nepalese Brahmins male and female. This research has helped to generate knowledge and understanding of craniofacial features of Nepalese Brahmins and derived norms for orthodontic diagnosis and treatment planning.

Introduction: Appropriate comparison of an individual’s craniofacial structure can be made when evaluated relative to his/her comparable peer group. However, McNamara’s Caucasian norms are being used for adult Brahmins cephalometric analysis.Objective: To determine cephalometric norms using McNamara’s analysis in adult Brahmins of Kathmandu and to compare the values within the group and with Caucasians. Materials & Method: Screening of 850 individuals aged 18-27 years was performed. Inclusion criteria were Angle’s Class I molar and canine relation with normal overjet and overbite, symmetric face with acceptable profile, without craniofacial abnormalities, orthodontic/surgical treatment in the past and without proximal caries or prosthesis. Lateral digital cephalometric radiographs of 41 selected adult Brahmins of Kathmandu (23 males and 18 females) were manually traced. Comparative test was conducted within adult Brahmins of Kathmandu and with Caucasian group at significance level p≤0.05.Result: Adult male Brahmins of Kathmandu were found to have larger craniofacial measurements: Effective Mandibular Length (p≤0.001), Maxillo-mandibular Differential  (p≤0.05) and Lower Anterior Facial Height (p≤0.01) than adult female Brahmins of Kathmandu. Adult Brahmins were found to have smaller craniofacial measurements compared to Caucasians.Conclusion: Gender and ethnic diversity must be considered during orthodontic diagnosis and treatment planning for an individual.

The article presents a case report of a teen age girl with Class II Division 2 malocclusion with deep over bite. The case was treated on non-extraction basis using 0.018 pre-adjusted edgewise appliance with anterior bite plate (monobloc) to correct deep bite and forward placement of the mandible. Use of Class II elastics helped to achieve Class I canine and molar retention. Treatment was completed in 22 months with good occlusion and facial esthetics.
