Anterior openbite – a cephalometric evaluation of dental pattern in bengali population

Background: There are large racial variations in the characteristic features of anterior open bite among different population groups throughout the world. The purpose of this comparative study was to find out significant dento-alveolar differences between Bengali anterior openbite and normal subjects to identify any peculiarity in dental factors that may help to categorize the dental pattern of anterior open bite in this particular population group. Methods: Lateral cephalometric films of 30 Bengali subjects having anterior open bite were compared with lateral cephalometric films of 30 normal Bengali subjects by dental parameters. Results: Statistically significant differences were found in two dental parameters. Conclusion: More acute interincisal angle and increased proclination of maxillary anterior teeth were found in anterior open bite subjects.
