To identify anatomic relationship between central incisor roots and alveolar bone thickness in individuals with variable sagittal malocclusions

Abstract

The predisposition of central-incisors and its association with alveolar bone in surrounding area required assessment before any decision for treatment which involves anteroposterior (AP) movement of incisor inside the jaws. To identify anatomic relationship between central incisor roots and alveolar bone thickness in individuals with variable sagittal malocclusions and to also correlate if any sexual dimorphism among samples. The present study was conducted on 100 pre-treatment lateral cephalograms of young adult patients aged 15 to 30 years. They were divided into 2 groups on the basis of Angle’s system of classification as Class I and Class II with 50 subjects each group. patients were selected from the pool of patients who reported to All the lateral cephalograms were hand traced by same operator and tracings included mandibular symphysis, 1 molar central incisors, the OP, incisal edges, root apices, incisor long axes, upper incisor CEJ and upper incisor root midpoint. Various parameters were then measured for both the groups. All data were analysed using the Statistical Package for the Social Sciences software (SPSS version 24.0 Inc, Chicago, IL, USA. Independent sample t-test was used to determine possible statistically significant differences between the Class I and Class II for various parameters. U1-lab was statistically significant increased value in Class I sample, Where as L1-ling was statistically significant increased value in Class II sample. A very small but significant difference was found for the  mandibular alveolar bone thickness in males and females in both Class I and Class II samples. A significant variance between alveolar (AV) process of class II and Class I occlusion. There was also a significant variation in males and females of the sample group.
