Objective: To compare the skeletal and soft tissue measurements of the dento-facial region in a cephalometric study done in the Pakistani population. Study Design: Comparative cross-sectional study. Place and Duration of Study: Armed Forces Institute of Dentistry, Rawalpindi Pakistan, from Feb to Aug 2019. Methodology: Total 160 subjects were enrolled in the study. Lateral cephalograms were recorded for all the study participants in natural head position. Patients were divided into Class I, II, and III according to the skeletal pattern. The distances of skeletal and soft tissue landmarks relative to the respective norm values and the angles between the Nasion Sella line and Frankfurt horizontal to the natural head position were measured and compared in the three classes using chi-square. Results: Out of 160 patients, 96 (60%) patients were males, and 64 (40%) were females. In our study, 92 (57.5%) patients were classed in class I, 46 (28.75%) in class II and 22 (13.75%) in class III. The mean score of A point, Nasion, and B point angle was 7.5 ± 1.112, while the beta angle was 30.5 ± 2.214. The mean score of facial convexity angle was 14.1 ± 2.124, while the mean vertical height ratio was 1.05 ± 0.11. Both skeletal and soft tissue measurements significantly predict the skeletal pattern and discrepancy (p-value <0.001). Conclusion: Lateral cephalograms and radiography measures emerged as reliable techniques to classify the patients in various skeletal patterns. Factors like age and gender do not influence skeletal discrepancies.

Objective: To compare the role of beta and A point-nasion-B (ANB) angles in evaluating the sagittal skeletal discrepancy in a cephalometric study done in the Pakistani population. Study Design: Comparative cross-sectional study. Place and Duration of Study: Orthodontics Department, Armed Forces Institute of Dentistry, Rawalpindi Pakistan, from Jul to Dec 2019. Methodology: A total of 150 subjects between the age of 18 to 25 years were enrolled in the study A point-nasion-B angle was measured using the lateral cephalogram in all the subjects and was divided into classes I, II and III. Beta angle was also measured in all the patients. Results: Out of 150 subjects, 92 (61.3%) patients were males, and 58 (38.7%) were females. The mean age of the subjects was 19.2 ± 2.138 years. 89 (59.3%) patients were classed in Class-I, 40 (26.7%) in class-II and 21 (14%) in class-III. The mean score of A point-nasion-B angles among the patients was 7.5 ± 1.112. The mean score for beta angles in the study participants was 30.5 ± 2.214. A point-nasion-B and beta angles both had a significant relationship with classes of skeletal discrepancies. Conclusion: Sagittal skeletal discrepancies can be evaluated with accuracy by using both A point-nasion-B and beta angles. Lateral cephalograms and radiography measures emerged as reliable techniques to classify the patients in various skeletal patterns. Factors like age and gender do not influence skeletal discrepancies.
