Abstract

Objective: This study aimed at determining variation of Tweed’s norms in male and female of West Bengal population. Materials and Methods: The study sample consisted of Standardized lateral cephalograms obtained from 50 subjects (25 males and 25 females) from West Bengal of 12-18 years age group with normal occlusion and pleasing facial profile. Tweed’s cephalometric analysis was performed and difference between male and female samples was recorded. Any association between the three parameters of tweeds analysis and gender of the subjects was also calculated. Results: Mean FMA value for females was found to be significantly higher than that of males (t48 = 2.97; p48 = 2.45; p Conclusion: The result of the study indicated difference in the norms of diagnostic facial triangle in males and females of West Bengal population.   Keywords: Tweeds analysis, Diagnostics facial triangle, Bengali ethnicity, Cephalometric study.

Abstract

Objective: The objective of this study was to evaluate and compare the amount of separation achieved by four different types of separators: elastic separator, kesling separator, Kansal separator and Dumbbell separator. Materials and Methods: 50 patients (25 males and 25 females) were randomly selected for the study that came to the department of orthodontics and dentofacial orthopaedics for fixed orthodontic treatment. All four types of seperators namely Elastomeric, Kesling, Kansal and Dumbbell separators were placed in each and every patient in all the four quadrants. Amount of separation was checked after 5 days of separator placement with the help of a feeler gauge. Data thus obtained was subjected to statistical analysis. Result: Result of the study showed that dumbbell separator was most efficient in separating the teeth followed by elastomeric separator. Dumbbell separator was found to be the fastest followed by elastomeric separator in separating the teeth. Kesling and kansal separator almost took same time to achieve adequate separation.   Keywords: Seperators, Kesling, Dumbbell separator, Kansal separator, Efficacy.
