Annals Punjab Med Coll Jan ;16(3):193-6.

Background: Tooth loss has multi-factorial etiology. Epidemiological evidence suggests association of tooth loss with age, gender, education, socioeconomic status, access to dental care, and health care system. A number of studies have been conducted worldwide to determine the pattern of tooth loss but recent data from Pakistan is not available. Objective: This study aims to find the association of age and gender with pattern of tooth loss. Study Design: A cross sectional study. Settings: Institute of Dentistry (IOD), CMH Lahore Medical College, Lahore Pakistan. Duration: Six months from January 2021 till July 2021. Methods: 335 participants for partially dentate arches were examined and information was recorded according to Kennedy’s classification system. Chi-square test was applied to determine significance and correlation of Kennedy’s class with gender and different age groups. Results: Most common pattern seen was Kennedy’s class III in both maxilla (65.7%) and mandible (62.7%) followed by Kennedy’s class II in maxilla (18.5%) and mandible (20.9%), then Kennedy’s class I in maxilla (14%) and mandible (14.9%) and lastly class IV in maxilla (1.8%) and mandible (1.5%). With increase in age, there was increase in Class II and Class I pattern respectively. Partially dentate arches were more common in females than males. All results were statistically significant, P-value ≤ 0.05. Conclusion: There is a significant association between pattern of tooth loss and gender. Class 1 is more frequent in older age group as compared to the younger in which class III is more commonly present. Caries is the most common cause of tooth loss followed by periodontal disease
