Abstract

The aim of this study was to establish the influence of sagittal dentoskeletal pattern on the value of angular profile parameters of the chin region, as well as to examine the significance of the established variations for each angle individually. This study included the examination and the analysis of cephalometric radiography derived lateral cephalograms to evaluate profile angles for 120 adult Caucasian subjects (60 male and 60 female) from the central Balkan region, aged between 18-30 years. The mentolabial angle, mentocervical angle (MCA) and cervicomental angle (CMA) are examined in subjects with different dentoskeletal pattern: Class I, Class II division 1, Class II division 2, and Class III. In our sample of subjects with Class I, the average value of mentolabial angle is 131.13 ± 14.17º. For that angle, there is significant differences established between subjects with Class I and Classes II division 1(P<0 P=0.048) P=0.001).>
