Abstract :
Background: Mandibular symphyseal morphology is a significant aspect in orthodontic treatment planning. The current research aimed at comparing the linear dimensional variations of the mandibular symphysis seen in various age groups with different growth patterns using CBCT.
Materials and Methods: Ninety CBCTs were segregated into three groups based on their growth patterns as horizontal (HGP), average (AGP), and vertical (VGP). Each group was additionally categorised into age-based subgroups such as Pre-adolescent (20 years). The symphyseal height and widths were measured along the midline and the lateral aspects. One-way analysis of variance (ANOVA) and the Bonferroni post hoc test were employed. The right and left sides were differentiated by applying the Independent-t test. Kendall Tau’s b correlation tests were performed to determine the relation between the measured parameters and age as well as the parameters with the growth patterns.
Results: In the pre-adolescent age group, a significant increase in symphyseal height and upper width was seen along the midline (P < 0>
Conclusion: The quantitative dimensions of the symphysis varied with increasing age in different growth patterns which is essential for preoperative surgical planning.
