Measurement of mesiodistal axial angulation of the teeth in class I malocclusion in adults

Abstract

ABSTRACT
Background: The study of the axial inclination of the individual teeth to each other is the most important step in the
process of case study and this study aimed to provide a description of the mesiodistal axial angulation of the
maxillary and mandibular teeth in cases of class I malocclusion.
Materials and methods: The values of the mesiodistal axial angulation of the teeth were measured for 20 subjects (10
males and 10 females) from orthopantomograph using computer program and comparisons were made between
the right and left sides and between males and females.
Results: showed that the mean values of the mesiodistal axial angulation of the teeth were higher in males than in
females, and higher on the right side in upper and lower arches than on the left side for males, females and total
sample, however; there was no statistically significant difference between the groups.
Conclusion: This study provided a good description of the mesiodistal axial angulation of the maxillary and
mandibular teeth in cases of class I malocclusion.
