“…These figures are higher than the school children of eastern Nepal as reported by Singh et al They found increased overjet in 17.51% and deep overbite in 13.23%. 3 However, Shrestha and Shrestha reported increased overjet in 43.8% subjects and increased overbite in 20.7%. 5 The significant association found between Angle's classification of malocclusion and underlying skeletal base is in accordance with the findings of Patrick et al The authors reported no significant association between gender and underlying skeletal base; which is also in accordance with the present study.…”

“…Although many studies have been conducted regarding the type and distribution of malocclusion in different regions of Nepal; [2][3][4][5][6][7] very few researches of such kind have been conducted in south-eastern Nepal. The objective of the study was to assess the pattern of distribution of malocclusion among orthodontic patients in south-eastern region of Nepal, to determine the association between dental and skeletal malocclusion, and to estimate the age of presentation of Class II malocclusion among the patients.…”

Introduction: Occlusal traits in orthodontic patients have been studied in different parts of Nepal. However, very few data are available on malocclusion in south-eastern region of Nepal.Objective: To assess the pattern of malocclusion occurring in orthodontic patients in south-eastern region of Nepal, and to estimate the age of presentation of Class II malocclusion among the patients. Materials & Method:Data were collected from 150 pre-treatment study models and lateral cephalograms from two orthodontic specialty clinics in Biratnagar. Angle's classification system was used to determine dental malocclusion and ANB angle was used to determine skeletal malocclusion. Chi square test was used to test the association between dental and skeleton malocclusions.

“…[15][16][17][18][19] The prevalence of malocclusion in Nepal varies from 73% to 90.4%. 1,20,21 Planning orthodontic treatment in the population requires data regarding malocclusion and its severity at the community level. Several studies were done to assess the severity of malocclusion in the population.…”

Introduction: Measurement of the severity of malocclusion is assessed with various indices among which Index of Orthodontic Treatment Need (IOTN) is widely used for clinical and epidemiological purpose. Objective: To find out the treatment need of patients who are undergoing orthodontic treatment.Materials & Method: 207 patients (71 male, 136 female) fulfilling the inclusion criteria were assessed for the dental health component (DHC) and aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN) by a single investigator. DHC was assessed with study models, whereas AC with intraoral frontal photograph.Result: Examination of DHC showed that 1 patient (0.5%) had no need; 20 patients (9.7%) had mild/little need; 50 patients (24.2%) had moderate/borderline need; 97 (46.9%) had severe need; 39 patients (18.8%) had extreme treatment need. Similarly, 7 patients (3.4%) had AC 1; 18 patients (8.7%) had AC 2; 13 patients (6.3%) had AC 3; 32 patients (15.5%) had AC 4; 34 patients (16.4%) had AC 5; 25 patients (12.1%) had AC 6; 18 patients (8.7%) had AC 7; 35 patients (16.9%) had AC 8; 15 patients (7.2%) had AC 9; 10 patients (4.8%) had AC 10.Conclusion: Among the patients who were undergoing orthodontic treatment, majority were in severe/extreme treatment need, however few with no treatment need were also found.Orthodontic Journal of Nepal, Vol. 6 No. 1, June 2016, pp.23-26

“…The epidemiological studies exploring malocclusion in Nepalese also found increased prevalence of Class I Figure 2. Scatterplot demonstrating the relationship between lower anterior facial height and ratio of maxillary lateral to central incisor malocclusion followed by Class II and III; [12][13][14][15] and hence it was quite common for such distribution in this study sample. No significant difference in R1 and R2 was found when compared between the two sides and the gender.…”

Background & Objectives: Maxillar y anter ior tooth to tooth proportion has a special value in dental esthetics. This study aimed to assess the apparent proportion of maxillary anteriors and possible association with lower anterior facial height and malocclusion type. Materials & Methods: One-hundred and sixty samples with well aligned maxillary dentition were selected and the lower anterior facial height was measured with digital caliper. Molar relationship was examined and intraoral frontal photograph was taken for digital measurement of tooth proportion. The ratio of maxillary canine to lateral and lateral to central incisors were measured and compared between gender and the sides. These ratios were further compared among various malocclusion type using ANOVA and its association with lower anterior facial height was evaluated with Pearson's correlation. Results: Most of the samples had Class I molar relationship (70%) followed by Class II (23%) and Class III (7%). The mean lower anterior facial height was 62.82mm and ratio of maxillary lateral to central incisor and canine to lateral incisor was 0.68 and 0.76 respectively. No statistically significant difference was found when the ratio was compared between the gender and the sides. These ratios were statistically different from the golden ratio and has no significant correlation with lower anterior facial height. These mean ratios were also found similar across the malocclusion type. Conclusion: Ratio of appar ent dimension of maxillar y canine to lateral incisor and lateral to central incisor was different from the golden ratio and showed no association with lower anterior facial height and malocclusion type.Key words: Golden pr opor tion; malocclusion; lower anter ior facial height; tooth proportion Citation: Gyawali R, Singh VP.
