Background: Indirect Pulp Cap (IPC) is a treatment that preserves pulp vitality. This study aimed to investigate the success rate of indirect pulp cap therapy as a conservative treatment for deep carious lesions in permanent teeth.
Materials and Methods: In this cross-sectional study, among the patients for whom IPC treatment was performed in 2015, 100 patients were randomly selected. Vital pulp tests (thermal, cold and electrical test) and pre-apical tests (percussion, tactility and chewing) were performed for the target tooth and control teeth. The tooth was examined radiographically and the signs of success or failure of treatment were examined, also.
Results: Of the 100 patients who received IPC, 91 had signs of a successful treatment after 4 years, and only 9 had failed. In other words, the success rate of the treatment was 91% and the failure rate of treatment was 9%.
Conclusion: According to the results of this study, IPC is an appropriate treatment for teeth with deep caries in both sexes and all ages, the type of the material used to seal the pulp and the restorative material used for dental restoration does not affect the success rate. But the most important factors are to apply the indirect pulp treatment carefully, avoiding bacterial contamination, and to seal the teeth with a hermetic restoration.
