Abstract

Malocclusion assessment methods are based on registrations and measurements made on study casts, which requires that impressions be taken. In addition to being costly and time-consuming, this process can be unpleasant for very young children. Therefore, the aim of this study was to evaluate the reliability of intra-oral measurements that compute a malocclusion index score to determine malocclusion severity in the mixed dentition. The research was part of a longitudinal study in Slovenia on a sample of 530 3-year-old children. At 8 years of age (mean 8.5 years, standard deviation 0.2), a cohort of 101 children (44 boys, 57 girls) was randomly selected in a cross-sectional study. Quantitative registrations of space and occlusal anomalies were performed intra-orally as well as on study casts. Kappa (kappa) statistics were used to evaluate the agreement between clinical and study cast malocclusion assessments. Systematic bias of measurements was tested using Wilcoxon's signed rank test. The results showed complete agreement between the two measurements for anterior crossbite, anterior open bite and overjet scores (kappa = 1); excellent reliability for the buccal segment relationship (kappa = 0.93), transverse occlusion of posterior...Continue Reading
