Secondary caries occur after dental restoration has been functional for some time; it is onsidered one of the main reasons due to which participants get their dental restoration enlaced. The problem of secondary caries is increasing day by day in a developing country like akistan, and with the economic constraints, it gets challenging for an individual to bear the onetary burden of getting restoration replaced or expensive treatment. Hence we aimed at ssessing the factors associated with secondary caries by which effective preventive strategies n be designed and implemented. bjective: ) To identify factors associated with secondary caries among adults aged 18-64-year-old isiting two dental teaching hospitals in Karachi, Pakistan ) To determine the frequency of secondary caries among adults aged 18-64-year-old isiting two dental teachings in Karachi, Pakistan ethod: cross-sectional study was conducted in two dental teaching hospitals in Karachi, Pakistan. A ample size of 203, participants aged 18-64 years were recruited from one private dental aching hospitals and one government teaching hospital via non-probability sampling. Data as collected through a structured questionnaire and oral examination by a licensed dentist. e questionnaire consisted of questions related to the individual's sociodemographic factors, ental restorations, diet. Oral assessment was done by the help of masks, gloves and mouth irror to look for the type of dental restoration, its location, amalgam cavity class, Caries was ssessed through DMFT index (decayed, missed, and filled), oral hygiene was assessed through ral hygiene index (good, fair and poor) and lastly bitewing/periapical X-ray of the restoration I was taken in order to diagnose secondary caries under the dental restoration (amalgam fi PFM crowns). Statistical analysis was performed using Stata version 14.2. Cox proportional hazard algorithm was used for data analysis and to report adjusted prevalence ra 95% confidence interval. tios and its RESULTS: From two hundred three participants, 84 (41.38%) were males, and 119 (58.62%) were females. were estoration, Cavity The frequency of secondary caries was 37.93%. We found four dental factors that associated with secondary caries in our study, which are the type of dental r class, DMFT score, and oral hygiene index. Total number of adults with (DMFT score > 0) were 127 (62.57%), in this score missed and decayed component contributed large) y,cavity class II cavi also had higher percentage of secondary caries 12 (40.00%), participants with poor oral hygiene had higher prevalence of secondary caries 33 (56.90%), lastly PFM crowns had higher percentage of secondary caries 67 (45.27%) as compared to amalgam fillings 10 (18.18%). Conclusion: Frequency of secondary caries found in this study is 37.93%. PFM crowns were more with secondary caries 67 (45.27%) as compared to amalgam filling 10 (18.18%). Factors affe cte like the type of dental restoration or restorative material used, cavity class, oral hygiene, people susceptibility to past caries experience, are essential factors for secondary caries to occur.
