The aim of this study was to correlate the morphological facial index and canine relationship in adults. Materials and method: The research was conducted on 1000 subjects (563 males and 437 females), aged 18-40 years, selected randomly. The parameters were morphological facial height and facial width. The standard spreading caliper with its scale was used for the measurement of facial parameters. Canine relationship was observed intra-orally with the subjects seated on the dental chair. Result: Euryprosopic facial type (53.2%) was most common in majority of the subjects followed by Mesoprosopic (21.6%), Hypereuryprosopic (19%), Leptoprosopic (5.6%) and the least common was Hyperleptoprosopic (0.6%). The canine relation was mostly Class I in both the genders, females showed a higher value of Class II and Class III canine relation. Conclusion: The overall majority had the euryprosopic facial type and there was no significant association between facial morphologic types and canine relationship in both the genders in different age groups at either side. The canine relationship association with facial morphologic type was significant only for left side.
AIM:The aim of this study was to evaluate sexual dimorphism in nasal proportions of Class I and Class II skeletal malocclusions in adults.MATERIAL AND METHODS:The sample comprised 120 patients (females 18 years and above and males 21 years and above), with no history of previous orthodontic treatment or functional jaw orthopedic treatment. They were divided into different groups based on point A-Nasion-point B (ANB) angle and gender. Groups I and II included 30 males and 30 females with skeletal class I malocclusion (ANB 0–4 degrees). Groups III and IV included 30 males and 30 females with skeletal class II malocclusion, respectively (ANB above 4 degrees).RESULTS:In regards to the comparison between males and females (Class I + Class II), nasal length (P < 0.001), nasal depth 1 (P < 0.001), nasal depth 2 (P < 0.001), nasobasal angle (P < 0.001), soft tissue convexity angle (P < 0.001), and nasal bone length (P < 0.008) were found to be statistically significant. Nasobasal angle was found to be significantly higher in females than in males (Class I) (P < 0.001). Nasolabial angle was prominent in class I males than in class I females (P < 0.001). Soft tissue convexity angle of Class I participants was significantly lower than that of Class II participants (P < 0.001), whereas nasobasal angle and nasomental angle of Class I participants were found to be significantly higher than that of Class II participants (P < 0.001).CONCLUSION:Sexual dimorphism was found in various nasal parameters. Significant amount of differences was found in the nasal proportions of Class I and Class II (male and female) participants.
Aim: The main aim of this study was to investigate the skeletal and dental relationships in individuals with various depth of curve of Spee in the vertical and horizontal plane. Material Methods: Pre-treatment lateral cephalograms and dental cast of 300 patients were taken. The subjects were divided into three groups according to the depth of curve of Spee. Group A (N=100) = Flat curve of Spee i.e. < 2mm, Group B (N=100) = Normal curve of Spee i.e. between 2-4 mm, Group C (N=100) = Deep curve of Spee i.e. >5mm. Four angular and four linear measurements were performed on lateral cephalogram. The measurements of the depth of curve of Spee, overbite, overjet and molar relation were made on dental casts. Results: In horizontal relationships Difference in overjet of the three groups was found to be statistically significant (p<0.001). Difference in molar relationship among Group A, Group B and Group C was found to be highly significant (p<0.001). SNA, SNB, ANB and Beta angle all were found not to be statistically different between the 3 groups. Difference in overbite of above three groups was found to be statistically significant (p<0.001). All the vertical skeletal parameters were found to be not statistically significant. Conclusion: Increase in overjet, overbite and Class II Molar relation were seen in cases with deep curve of Spee (Group C). All horizontal and vertical skeletal parameters were not influenced by change in different depth of curve of Spee.
Objective: To assess the prevalence of malocclusion and orthodontic treatment need among the rural school going 15‑years-old children Materials and Methods: A descriptive cross sectional study was carried out among 400 school going children in the central part of India. Occlusal features such as overjet, overbite, crossbite, crowding, and spacing were documented using a structured proforma and the need for orthodontic treatment was evaluated using the index of orthodontic treatment need dental health component. Results: It was found that the prevalence of malocclusion among the study participants was 70%, and the overall treatment need was 29.5%.Conclusion: This study offers baseline data on the need and demands for orthodontic treatment within the sample, which is critical for public orthodontic and dental service planning.
