AbstractIntroduction: To describe the cephalometric vertical characteristic of skeletal Class II malocclusion in South Rajasthan population at Daswani Dental College and Research Center. Methods: A total of 100 lateral cephalograms of pre-orthodontic patients with skeletal Class II malocclusion were obtained from Daswani Dental College and Research Center. The lateral cephalograms were taken using digital cephalometric machine and were analyzed by manual tracing with experienced post graduates to determine the ANB, mandibular length, facial axis, Y‑axis, sella to nasion‑mandibular plane (SN‑MP), lower anterior facial height (LAFH), FMA, gonial angle, saddle angle and articulare angle Correlation between mandibular length and other variables was analyzed using Pearson correlation test with P < 0.05. Results: Increased ANB, short mandibular length, negative value of facial axis, large value of MP angle, Y-axis, and LAFH. There was also a significant correlation between mandibular length and various variables, namely, facial axis, ANB angle, and LAFH. Conclusions: Skeletal Class II malocclusion in South Rajasthan population at Daswani Dental College and Research Center was characterized by short mandibular length and large ANB mostly not by the increased of SNA but by the lack of SNB.
