Cephalometric comparison between male and female using Tweed's analysis in solan population

Aim: The purpose of this study aimed to verify the mean values of cephalometric values of Tweed's facial triangle: Frankfort-mandibular plane angle (FMA), Frankfort mandibular incisor angle (FMIA), and Incisal mandibular plane angle (IMPA) of Class II malocclusion patients in Solan population and conduct comparison between male and female. Materials and Methods: Cephalometric radiographs of eighty patients having Class II malocclusion, taken from the Department of Orthodontics and Dentofacial Orthopedics, Bhojia Dental College and Hospital, Baddi. Samples were divided on the basis of gender that is 40 males and 40 females. The following three angles formed in Tweed's triangle were measured for all the subjects: FMA, FMIA, and IMPA. Taking these angles, the mean of all the Tweed's parameters of male and female was depicted. Result: The mean value indicates that the people of Solan district show an average growth pattern. The FMA in males (23.625) was less than that of females (26.3), FMIA was slightly more in male (56.33) than female (55.8) and the IMPA was also more in males (100.1) than females (97.9). Conclusion: The study showed no significant difference in the values between male and female; therefore, it is not desirable to have separate norms for diagnosis and treatment planning for the treatment of Class II malocclusion in male and female.
