Correlation between Bolton Ratios and Different Facial Types

Abstract

Aim: To correlate the Bolton ratios with vertical facial types. Methods: This cross-sectional study was conducted at Department of Orthodontics, Faisalabad medical university and de’Montmorency College of dentistry; in which 90 lateral cephalograms and plaster casts of untreated patients were included. The patients were divided into three groups as per facial type; mesofacial, dolichofacial and brachy facial. Bolton ratios were calculated on model while SNMP, MMA, and Jaraback ratio were calculated on lateral cephalograms. The data was correlated and analyzed using SPSS version 20.0. Linear regression analysis was used to calculate Pearson’s correlation coefficient for determination of correlation between the two variables. Duration of this study was January 2017 to October 2017. Results: Statistically insignificant correlation exists between bolton ratio & facial types. Conclusion: It was concluded that Bolton ratios and vertical facial types are not correlated.
