Anterior open bite- a cephalometric evaluation of skeletal pattern in bengali population

Background: There are racial variation in the characteristic features of anterior openbite among different population groups in the world. The purpose of this comparative study was to find out significant skeletal differences between Bengali anterior openbite and normal subjects to identify any peculiarity in skeletal factors that may help to categorize the skeletal pattern of anterior openbite in this particular population. Methods: Lateral cephalometric film of 30 Bengali subjects having anterior openbite were compared with lateral cephalometric film of 30 normal Bengali subjects by skeletal parameters. Results: Statistically significant difference were foundin skeletal pattern between the groups. Conclusion: Bengali open bite subjects are mainly characterized by long lower anterior face, vertical growth pattern with downward & backward rotation of mandible.
