title: Carabelli's anomaly in a Karnataka town of south India.
abstract: A total of 3,656 subjects (M = 1,893., F = 1,763) comprising 1,560 children with deciduous teeth (M = 796., F = 764) and 2,096 individuals with permanent teeth (M = 1,097., F = 999) were studied for the Carabelli's anomaly. The trait occurred with higher proportions in females with deciduous teeth (38.4%) and males with permanent teeth (29.2% than in their counterparts. Significant differences were observed in the occurrence of the anomaly between upper and lower income group children with deciduous teeth (chi 21 = 4.7139), and between upper and middle income group persons with permanent teeth (chi 21 = 5.4987). There were no significant differences between other religious groups and Hindu communities. The incidence of the cusp is slightly more in younger children with deciduous teeth (below 5 years) than in others. No consistent trend was observed in persons with permanent teeth.
