Evaluation of the Success Rate of Indirect Pulp Capping Treatment using Different Materials: A Clinical Study

Abstract

Abstract The aim of this clinical study was to evaluate the success rate of indirect pulp capping (IPC) treatment with three pulp capping materials; Dycal, Biner LC, and TheraCal LC in permanent premolars and molars teeth. A total of 200 permanent posterior teeth with deep carious lesions indicated for IPC treatment were included in the study. The number of patients was 130 of both genders, age 18-55 years old. Teeth were divided into three groups according to the material used for pulp capping. IPC treatment was performed using Dycal, Biner LC, and TheraCal LC in 67, 68, and 65 teeth respectively. Teeth were then restored with nanohybrid resin composite. Patients were clinically evaluated at 8 weeks, 6 months, and one year follow up period for the success of IPC treatment. Data were statistically analyzed using SPSS software. A high success rate of IPC treatment was observed with the three pulp capping materials and that there was no statistically significant difference between the three investigated groups (P˃0.05). At one year evaluation period, the success rate of Dycal, Biner LC, and TheraCal LC was 97%, 97.1, and 98.5% respectively. The three materials were exhibited a high success rate and found to be very successful as IPC agents; however, TheraCal LC showed the best results up to one year follow- up period. I PC treatment maintained the pulp vitality and function of the restored permanent teeth, and that the success of IPC treatment is independent of the pulp capping material.
