Evaluation of Four Pulpotomy Agents in The Primary Teeth

Objectives: The aim of this study is to evaluate the formocresol (F), ferric sulphate (FS), calcium hydroxide (CH) and mineral trioxide aggregate (MTA) pulpotomies in primary teeth both clinically and radiographically. Methods: This study consisted of 88 patients with an age range of 5-9 years old. Totally 147 primary teeth with deep caries were treated with 4 different pulpotomy agents and restored with composite resin. The inclusion criteria were to have no clinical and radiographic evidence of pulp pathology. Clinical and radiographic success and failures and dentin bridge formations were recorded at 3, 6, 12, 18 and 24 months follow-up. The difference between materials were analyzed using the Chi-square test and Kaplan-Meier analysis. Results: In all maesurement times the clinical and radiographic results were acceptable. The clinical and radiographic results were demonstrated that there were no statistically significant differences among materials. Besides, dentin bridge formations were observed in the CH and MTA groups. Conclusion: All of these materials are successful as pulpotomy agent in the primary teeth, however CH and MTA have advantages as they promote dentin bridge formation and are biocompatible.
