Clinical and Radiographic Evaluation of Pulpotomy using MTA, Biodentine and Er,Cr:YSGG Laser in primary teeth- A Clinical Study

Abstract

Background: The aim of the study was to compare the clinical and radiographic evaluation of pulpotomy using mineral trioxide aggregate (MTA), calcium silicate-based cement (Biodentine), and Er,Cr:YSGG laser in primary molars.

Materials and methods: Fifty-four primary teeth were selected for this study as per the inclusion and exclusion criteria in the age group of 4-9 years and then randomly allocated to three groups A, B & C. In group A, after removal of coronal pulp, MTA was placed at the floor of pulp chamber. In group B, calcium silicate-based cement (Biodentine) was placed at the floor of pulp chamber. In group C, decontamination of the cavity was done with Er,Cr:YSGG laser. This was followed by placement of permanent restorative material in all the groups. Clinical and radiographic success was evaluated at 3, 6 and 9 months. Data analysis was performed using Statistical Package for the Social Science-21 (SPSS-21).

Results: At the end of 9 months, overall success rate of pulpotomy was 85.5%. There was no significant difference among the three groups (p > 0.05).

Conclusion: The study showed that the success of pulpotomy procedure is independent of the type of medicament used for pulpotomy. Moreover, the study also shows that Er,Cr:YSGG laser can be effectively used for pulpotomy procedures.
