Materials and Methods: 300 subjects of age ranged from 12 - 55 years were selected from the camps organized by Department of Public Health Dentistry, Kothiwal Dental College, Moradabad in the month of March 2009. The sample was restricted to population, who were permanent residents of Garhwal region. Results: The prevalence of the carabelli structure was 60% with a bilateralism of 83.6% in the first maxillary molars and 74.6% in the second molars. The Carabelli structure was found to be 27.3% as a groove expression and 32.7% as a cusp expression. The prevalence of caries in the Carabelli structure was 18.1% for the first molars and 16.2% for the second molars. For the groove expression, caries prevalence was 4.3% in the first molar and 5.9% in the second molar. And for the cusp expression, it was 13.8% in the first molar and 10.3% in the second molars.
