Determining the Correlation Between Maxillary Anterior Teeth Size with Bitragion Width, Wrist Width, Interpupillary Width, Nasal Height in Indian Population and Using These Anthropometric Measurement as A Guide For Selecting Maxillary Anterior Dimensions

Abstract

Background: The vast number of combinations such as face form and size, Sex, Personality, and Age factor are utilized for determining the anterior tooth dimension. Whenever possible, it is advisable to record the form and shape of the natural teeth before extracting them. However, several anatomic entities and anthropometric measurements are used as a guide to select anterior teeth dimensions, but which is the most reliable indicator to determine the maxillary anterior teeth dimensions remains unclear. The study aimed to determine the correlation between maxillary anterior teeth size (Right Maxillary central incisor Length, Right Maxillary central incisor Width, Intercanine distance) with Bitragion width (BW), wrist width (WW), interpupillary width (IPW), Nasal height (NH) in Indian population. Material & Methods: Measurements of intraoral and extraoral landmarks made using Digital vernier caliper & Measuring tape in 173 subjects with an age range from 19 to 87 years were randomly selected fulfilling the inclusion and exclusion criteria. Results: The present study found that statistically significant difference (0.001) and strong correlation between Right maxillary central incisor length & width, and Intercanine distance with wrist width, nasal height & interpupillary distance, whereas, it is not significant between Right central incisor length & width, and Intercanine distance with Bitragion width. Conclusion: The results suggested that a high degree of correlation was seen between Wrist width, interpupillary width, nasal height, and maxillary anterior teeth dimensions. Hence, these anthropometric measurements can also be used for determining the maxillary anterior dimension in edentulous patients.
