Examination of 6 and 12 month follow-up of calcium hydroxide and calcium silicate materials used in direct and indirect pulp capping

Abstract

BACKGROUND: Pulpal vitality is important for the tooth to maintain its physiological function and preserve its structure. OBJECTIVES: The aim of this study was to evaluate the clinical and radiographic 6- and 12-month treatment success of calcium hydroxide (CH) and calcium silicate materials in indirect pulp treatment (IPT) and direct pulp capping (DPC) in teeth with deep dentin decay. MATERIAL AND METHODS: The study included 143 teeth of patients aged 17-69 years with no systemic disease. The study is grouped under 3 main groups (Dycal, Biodentine, TheraCal PT). Direct pulp capping was applied to 65 teeth and IPT to 66 teeth. All teeth were restored with Universal adhesive system and Universal composite (G-Premio Bond; GC Corp., Tokyo, Japan). RESULTS: In the statistical evaluations of the data obtained, 0.05 was accepted as the level of statistical significance. The general success rate in the IPT group was found to be 95.2% for Biodentine (Septodont, SaintMaur-des-Fossés, France), 91.7% for Dycal (Dentsply/Caulk, International Inc. Milford, USA) and 90.1% for TheraCal PT (Bisco Inc., Schaumburg, USA) at both 6 and 12 months. When the clinical and radiographic success was compared at 6 months and 12 months, no statistically significant difference was determined between the materials (p > 0.05). In the clinical and radiographic evaluations at the end of 6-month follow-up in the DPC group, the success rates were determined to be 96.0% for Biodentine, 81.8% for Dycal and 63.2% for TheraCal PT. At 12 months, these rates were 96.0% for Biodentine, 68.2% for Dycal and 63.2% for TheraCal PT. DPC Biodentine was found to be the most successful material (96.0%). CONCLUSIONS: At the end of the 12-month follow-up period, it was considered that the 3 materials (Biodentine, Dycal, TheraCal) can be selected for IPT. In DPC, Biodentine was found to be more successful than both calcium silicate containing resin and CH.
