Evaluation of average Frankfort mandibular plane angle in West Rajasthan population

Introduction: The relationship between the malocclusion and the facial form has been a focus for Orthodontists since the early 20th century. Cephalometrics can be utilized to describe, compare and classify the nature of orthodontic problems. Since well-established Indian ethnic norms are lacking, norms derived for Caucasian population are routinely used for investigations. Rajasthan is one of the largest state in India and Mewar is one of the major areas of it. With the increasing number of children of Rajasthan seeking professional treatment for malocclusion, it has become apparent that there is need to determine what constitutes a pleasing or normal face for the children of Rajasthan. A comprehensive and accurate diagnostic assessment of any orthodontic patient involves the comparison of the patient’s cephalometric findings with the norms of his or her ethnic groups or racial groups or subgroups. Materials and Methods: This study was conducted on 100 lateral cephalographs which were selected from the records in the Department of Orthodontics and Dentofacial Orthopedics. Results: According to results there was a higher FMPA in males than females in Western Rajasthan population. While observing the overall result no significant difference was observed in FMPA between male and female population of Western Rajasthan. Conclusion: The present study was undertaken to develop cephalometric norms of Tweed’s diagnostic facial triangle for West Rajasthan population and to find out any variation from Caucasian standard. The result of the study indicated that separate norms should be considered forWest Rajasthan males and females during diagnosis and treatment planning.
