Clinical and Radiographic Evaluation of MTA, Biodentine, and A New Resin-Modified Calcium Silicate As Pulpotomy Agents in Primary Mandibular Second Molars- A Clinical Study

Abstract Background: Pulpotomy is the most commonly performed vital pulp therapy in pediatric dentistry to maintain primary tooth vitality. Among materials used for pulpotomy, Mineral trioxide aggregate (MTA) and Biodentine (BD) have shown strong regenerative potential. Recently, a dual-cured resin-modified calcium silicate material—TheraCal PT was introduced primarily for pulpotomies. Aim: To compare the clinical and radiographic success of pulpotomy in primary mandibular second molars using TheraCal PT, MTA and Biodentine at 3, 6 and 9 months. Materials & Methodology: Forty-Five patients of age 6-9 years having carious primary mandibular 2nd molar involving only coronal pulp were selected based on the inclusion and exclusion criteria. They were randomly allocated into 3 study groups based on pulpotomy medicament used: Group A- MTA (15), Group B- Biodentine (15) and Group C- TheraCal PT (15). Caries was excavated under local anaesthesia, hemostasias was achieved after removal of coronal pulp using spoon excavator and capped with MTA or Biodentine or TheraCal PT according to the groups. Clinical and radiographic success was evaluated by a blinded calibrated evaluator after 3,6 and 9 months. Results: The difference in the clinical and radiographical success rate of three pulpotomy agents, were statistically significant (P<0.05). Biodentine has showed high success rate both clinically as well as radiographically which is significant statistically (P<0.05). Conclusion: Based on the clinical and radiographic observations, it is concluded that Biodentine has high success rates as a pulpotomy agent as compared to other two materials.
