Abstract

Aim and Objectives: The aim of the study is to establish a correlations between MPP-DPP metrics, ANB angle and Witts appraisal, as well as to determine whether perpendicular drawn from the centroids of the premaxilla(M) and mandibular symphysis(D) to the palatal plane can be utilised for identifying sagittal dysplasia in lateral cephalometric radiographs.
Background: Orthodontic diagnoses has relied heavily on radiographic cephalometry. The limited validity of current assessment techniques, vertical jaw relationships, and growth-related jaw rotations have made evaluating sagittal jaw relationships difficult and also they are less vulnerable to factors that could compromise accuracy and have a reduced measurement error, linear measurements have clear advantages over angular measurements.
Materials and Methods : lateral cephalometric radiographs of 90 individuals were included in this study and were divided into 3 groups based on their sagittal relationship,(Class 1, class 2, class 3). A perpendicular was drawn from point M(centroid of premaxilla) and point D(centroid of mandibular symphysis) to the palatal plane and the linear distance measured was compared to ANB and Witts appraisal.
Results: The mean MPP -DPP values in Class I subjects was 3.222 ± 1.435, Class II subjects was 8.672 ± 2.443, and in Class III subjects was -6.410 ± 2.535 and this mean difference between 3 Skeletal classes was statistically significant at p<0> Conclusion: This study showcases the promise of MPP-DPP metrics as supplementary indicators in orthodontic diagnosis and treatment planning. The strong positive correlations identified between MPP-DPP, ANB, and Wits appraisal underscore their value in evaluating sagittal jaw relationships.
