Abstract

Background: Estimation of the mesio-distal width of permanent maxillary canines (PMCs) is a critical part of mixed dentition space analysis. The aim of this pilot study is to find a specific prediction equation for the estimation of the mesio-distal width of PMCs depending on the width of permanent maxillary and mandibular central incisors (PMMCIs) in a Kurdish population. Methods: A hundred study casts were collected. The mesio-distal widths of the PMMCIs and PMCs were measured by digital caliper. Linear regression tests were applied to find the prediction equation using the sum width of PMMCIs as predictors. Results: The mean age of the subjects was 17.2 ± 2.39 years old. Statistically significant differences in the mesio-distal widths of PMMCIs and PMCs were found between males and females (p = 0.0001). Furthermore, statistically significant correlations were identified between the widths of PMMCIs and PMCs in both males (r = 0.633, p = 0.0001) and females (r = 0.717, p = 0.0001). Likewise, the mesio-distal width of PMMCIs was found to be a significant predictor of the width of PMCs in both males (R2 = 0.403, p = 0.0001) and females (R2 = 5.14, p = 0.0001). Conclusion: For the first time, regression equations were developed for a Kurdish population and can be useful as a part of a mixed dentition space analysis in Kurdish children.

Summary

Introduction

Predicting the development of occlusion in children and adolescents is of paramount importance for dentists providing dental care for them [1]. Mixed dentition space analysis (MDSA) is critical in early diagnosis of malocclusion as many malocclusions may emerge in the age range of 6 to 12 years; a proper intervention at this time would be helpful to prevent or minimize the severity of the malocclusion [2]. Estimation of the mesio-distal width of permanent maxillary canines (PMCs) is a critical part of mixed dentition space analysis. The aim of this pilot study is to find a specific prediction equation for the estimation of the mesio-distal width of PMCs depending on the width of permanent maxillary and mandibular central incisors (PMMCIs) in a Kurdish population.
