Popis: Background and Objectives: Evaluating the sagittal apical base relationship during orthodontic diagnosis and treatment planning is an important step. This study was aimed at comparison of Beta angle, ANB angle and Wit’s appraisal for assessment of sagittal skeletal discrepancy. Materials and Methods: Eighty six young adults (43 female and 43 male) were selected from the patient’s reporting to Department of Orthodontics, College of Dental Sciences, Davangere, India. Family lineage was studied to know the nativity of Davangere. The standardized pre-treatment lateral cephalogram of the chosen sample was traced. The sample was divided into three skeletal pattern groups: Class I, Class II and Class III, based on the ANB angle and profile, Beta angle was assessed in each group. Statistical Analysis: The data was subjected to statistical analysis student’s t-test, ANOVA test and correlation and regression analysis, using the software namely SPSS Software version 13. Microsoft word and Excel were used to generate graphs and tables. Results: In the local Davangere population, Class I skeletal pattern group exhibited Beta angle between 26º–34º, Beta angle less than 27º was found in Class II skeletal pattern, and Beta angle greater than 32º was seen Class III skeletal pattern. The coefficient of variation of Beta angle in all the three groups was significantly homogenous compared to ANB angle and Wits appraisal. The correlation and regression analysis of the total sample indicated a highly significant correlation between Beta angle and ANB angle (p
