Clinical and radiographic comparison of biodentine, mineral trioxide aggregate and formocresol as pulpotomy agents in primary molars.

Abstract

To compare the clinical and radiographic success rates of three different pulpotomy agents in primary molars after 18months. The study was carried out with 51 primary molars of children aged 5-9years old. The teeth were randomly assigned to the experimental or control groups. After coronal pulp removal and haemostasis, the remaining pulp tissue was covered with Biodentine® or mineral trioxide aggregate in the experimental groups. In the control group, formocresol was placed with a cotton pellet over the pulp tissue for 5min and after removal the pulp tissue was covered with zinc oxide-eugenol (ZOE) paste. All teeth were immediately restored with reinforced ZOE base and resin modified glass-ionomer cement, and later with pre-formed metal crowns. Follow-up assessments were carried out after 3, 6, 12 and 18months. Forty-five teeth were available for follow up at the end of 18months. All of the available teeth for mineral trioxide aggregate and Biodentine® were clinically successful, as were 73.3% of the FC group. Radiographic success rate for the formocresol group at 18months follow up was 73.3, 100% for mineral trioxide aggregate and 86.6% for Biodentine® group. Mineral Trioxide aggregate and Biodentine® showed more favourable results than formocresol.
