Dental caries is one of the most prevalent chronic diseases of people worldwide. Secondary caries is a disease that occurs on the tooth surface after the restoration has been used for a period of time. It is also known as recurrent caries and is predominantly seen cervically or gingivally on restorations.The aim of the study was to evaluate the association of gender and tooth position with secondary caries in class V restoration. Data was collected from June 2019 to March 2020 from the patient records of an institution, Chennai. The inclusion criteria included individuals with an existing restoration, adults above the age of 18 years. d=Data was entered and excel tabulation was done in a methodical manner: [ serial number-age-name-gender-tooth number-presence of secondary caries-site] and statistical analysis using SPSS was done to obtain results.Out of the 28 cases in the study, 23 (82.15%) were males and 5 (17.85%) were females. 11 patients (39.28%) had secondary caries in relation to class V restoration in anterior region and 17 patients (47.22%) in posterior region.Within the limitations of this study, it was concluded that male population had more often secondary caries in association with class V composite restoration than the females. Posterior teeth had more association with secondary caries in class V composite restoration than the anterior teeth. However gender did not affect the presence of secondary caries on teeth sites.
