Factors affecting the outcomes of direct pulp capping using Biodentine

Introduction This study aimed to evaluate the prognostic value of factors with regard to the treatment outcome of direct pulp capping using Biodentine (Septodont, Saint-Maur-des-Fosses, France), in permanent teeth in which the pulps were exposed during caries removal. Methods Between 2010 and 2014, 112 teeth with deep carious lesions underwent direct pulp capping. The patients were followed up at 2-3 months and 1-1.5 years with a routine examination on both recall visits. Periapical radiographs were taken at 1-1.5 years. Lack of patient complaints, positive reactions to cold and electric testing, no sensitivity to percussion, and no widening of the periapical ligament indicated success. The Fisher exact test was used for statistical analysis. The significance level was P = .05. Results Eighty-six teeth were available for 1-1.5 years follow-up. The overall success rate was 82.6%. Only age had a significant effect on the pulpal survival rate: the success rate was 90.9% in patients younger than 40 years and 73.8% in patients 40 years or older (P = .0480). Sex, initial or secondary caries treatment, occlusal or cervical/proximal caries, delayed placement of permanent filling, tooth position, and arch type did not influence the outcome. Conclusions A patient's age influenced the outcome of direct pulp capping using this new calcium silicate cement.
