Background: This study was aimed to evaluate the risk of developing secondary caries among subjects with FDPs in relation to oral hygiene status. Material and methods: To gather information on the patients' FDP complications as well as oral hygiene status, clinical as well as radiographic examinations were carried out. Secondary caries was examined as the primary clinical parameter. The effects of complications like fractures, debonding, and the requirement for endodontic care were also examined. From the time of therapy through the period of follow-up, the interval survival rate as well as cumulative survival rate of FDPs had been examined. Results: A total of 100 participants had been assessed for this investigation. Patients made up 51% of women and 49% of men. A total of 200 FDPs, including 40 veneer restorations, 110 crowns, and 50 bridges, were assessed. Regarding the materials utilized, 130 prosthesis (65%) were manufactured of porcelain fused to metal (PFM), while 130 prostheses (35%) were created entirely of porcelain. There were 63 FDPs (31.5%) with secondary caries, 79 (39.5%) with fracture (or chipping), 19 (9.5%) with debonding, and 39 (19.5%) with the requirement for endodontic therapy.In total, 200 FDPs had these four problems. In this study, 36 of the 115 female patients who received FDPs (31.3%) had secondary caries.For the male patients, secondary caries was linked to 27 out of 85 prosthesis (31.7%). Conclusion: In patients with FDPs, good dental hygiene can significantly lower the likelihood of secondary caries. Among subjects having poor dental hygiene, secondary caries is a prevalent consequence.
