Abstract

Introduction: The aim of this study is to ascertain the height, thickness, and height-to-thickness ratios of the mandibular symphysis with different sagittal and vertical patterns.
Methodology: This cross-sectional study examined 101 lateral cephalograms of untreated orthodontic patients. Adults (18 to 45 years) of either gender who had lateral cephalograms were included. All cephalograms were traced and examined by a single researcher. Anteroposterior (AP) & vertical skeletal measurements were taken in all participants in relation to symphyseal height, thickness, & ratio between height & thickness. SPSS-26 was used for data analysis.
Results: A non-significant difference was found in anteroposterior and vertical skeletal measurements among males and females. There were no major variations in symphyseal dimensions when analyzed with respect to the anteroposterior skeletal classification (ANB°). Significant associations between the three symphyseal measures and Gonial angle were found in males.
Conclusions: Males had higher mean symphyseal vertex, thickness, & height-thickness ratio than females. AP skeletal categorization was not substantially correlated with symphyseal height, thickness, or ratio (ANBo).Significant relationships existed between Gonial angle & symphyseal height, thickness, & ratio.
