The Relationship Between Tooth Size Harmony and Skeletal Deformities

Abstract

 Aim: The aim of this study is to detect the relationship between tooth Size Harmony and Skeletal Deformities and the gender on the other side.

Materials and Methods: The study sample consisted of 200 patients (100 m,100 fem), ages ranged between 18 and 25 years, they were divided according to the skeletal relationship into 5 groups (40 patients in every group); skeletal class I, skeletal class II, skeletal class III, deep Bite and open Bite. The skeletal relationship of patients was defined upon the cephalometric analysis then the casts were studied to determine the tooth size harmony by using the partial -and total Bolton analysis and Tons' relationship. it was calculated the tooth size harmony in every group and compared with the other groups by using the one-sided analysis of variance (ANOVA) to study the significant differences between the average dental analyzes in the studied groups. A t-test analysis of independent samples was also conducted to study the differences in dental analyzes between females and males in the studied groups.

Results: the results reviled that the differences between the averages of tooth size harmony in the five studied groups or according to the skeletal relationship and it was found that there were no significant differences between males and females within each group by (p>0.05).

Conclusions: There was no obvious correlation between the tooth size harmony and the skeletal relationship and no gender correlation within every group.
