Derin Çürüğün Yumuşak Dentine Kadar Selektif Olarak Uzaklaştırıldığı Dişlerin Pulpasının Korunmasında Kullanılan Kalsiyum Silikat Simanın Etkinliğinin Araştırılması

Abstract

The aim of this randomized controlled clinical study had been to evaluate the 18-month clinical performance of a resin-modified calcium silicate-based liner material (TheraCal LC, Bisco, Schaumburg, IL, USA) used as a pulp capping agent in teeth with deep carious lesions in which caries had been selectively removed to soft dentin. A total of 94 teeth in 80 patients with deep dentin caries classified as D3 according to the American Dental Association Caries Classification System (ADA CCS) had been included in the study. All clinical procedures had been performed by a single operator under rubber dam isolation. During caries excavation, soft carious tissue had been intentionally left over the pulp to prevent pulp exposure, while the peripheral caries had been removed until hard dentin was reached in order to obtain an appropriate surface for adhesive restoration. The teeth had been randomly assigned to two groups: a test group treated with TheraCal LC (n = 47), and a control group treated with Dycal (Dentsply Caulk, Milford, DE, USA) (n = 47). Over the pulp capping materials, a resin-modified glass ionomer cement (RIVA LC, SDI, Bayswater, Australia) had been applied, and all teeth had been restored with Gradia Direct Posterior (GC Corp., Tokyo, Japan). Clinical evaluations had been conducted at 6, 12, and 18 months by two independent examiners according to the FDI criteria. By the end of the 18-month follow-up period, all teeth in both groups had maintained vitality, and the overall clinical success rate had been determined to be 100%. No difference had been found in clinical performance between TheraCal LC and Dycal. In conclusion, in deep dentin lesions treated with selective caries removal, both TheraCal LC and Dycal had yielded similarly successful clinical outcomes over the 18-month follow-up period.
