Association Of Molar Angulation With Anterior Crowding And Dental Inclinations

Abstract

Objective: To determine the association between molars angulation, anterior crowding and dental inclinations Methods: This descriptive cross sectional study was conducted from June 2020 to August 2020. Pre treatment records (lateral cephalograms and dental casts) of 82 individuals were selected from the database of the Orthodontics Department. Angulation of molars and incisors inclination was evaluated from the lateral cephalograms. Anterior dental crowding in upper and lower arches was measured with the help of digital calipers using Little,s irregularity index. Correlation among molars angulation, anterior dental crowding and incisor inclination was measured with the help of Pearson,s product moment correlation. Results: Out of 82 patients 39 were males and 42 were females. Mean age of the patients was 17 + 3 years. Results showed that a positive but insignificant correlation was found between angulation of upper and lower molar and anterior dental crowding. A positive and significant correlation was found between angulation upper 1 st molar and upper incisors inclination. Similar relationship was also determined between lower 1 st molars and lower incisor inclinations. Conclusions: It was concluded that there was no association between the angulation of posterior teeth and anterior crowding in both arches. Also the angulation of incisors changed according to the angulation of molars in both arches.
