Background: This study evaluated the correlates for tooth extraction among patients between the age group 15-50 years Method: A cross-sectional hospital based survey in Bangalore city, India was conducted among patients attending four major Government Hospitals during April 2005 and November 2005.A total of 2014 patients participated in a clinical examination and completed interviews. Results: A total of 2314 teeth were extracted among 2014 patients. Majority of them were females who constituted 56% (1134) and 880 (44%) were males. Among both the sexes in all age groups, dental caries and periodontal diseases contributed to 54.7% and 29.7% of tooth loss respectively. Impactions, orthodontic reasons, prosthetic reasons, trauma, pericoronitis, prior to radiation therapy and miscellaneous reasons contributed to 15.6% of tooth loss. On the whole, the tooth mortality rate per person in males was 1.25 and in females 1.27. This was statistically significant. (F-value 53.70, p = 0.000). The lower socioeconomic classes (upper lower and lower class) contributed to 55.57% of overall teeth lost where as the upper class had only 8% of the teeth lost. Females lost more number of teeth than males in orthodontic, pericoronitis, impaction and prosthetic groups. Due to traumatic reasons like falls and accidents, males lost more number of maxillary incisors and maxillary second molars. Conclusion: Caries was the principle cause of tooth loss and molar teeth were the teeth most commonly lost. The results are consistent with prevalence and extent of tooth loss due to caries and due to reasons other than caries being differently related to disease- and socio- behavioral risk indicators.
