Utility of beta angle in assessing the sagittal skeletal discrepancy - a cephalometric study

Of the three dimensions, sagittal discrepancies are more commonly encountered in day to day practice, The purpose of the study was to assess the Beta angle. Pretreatment lateral cephalograms of 100 young adults (50 men and 50 women) were divided into skeletal Class I, Class II and Class III. The Data was subjected to statistical analysis using the Statistical software namely SPSS 11.0 and Systaf 8.0. The results of the present study showed that the mean Beta angle of 32.54 ± 0.86. There was statistically insignificant difference in Beta angle of male and female. A more acute Beta angle indicates Class II skeletal pattern, and a more obtuse Beta angle indicates Class III skeletal pattern.
