Comparative evaluation of a modified endodontic approach using Curcuma longa L. and conventional pulpectomy in primary molars: A randomized clinical trial.

Background: Turmeric (Curcuma longa) is known for its anti-inflammatory and anti-septic properties.

Aim: The aim is to compare a modified endodontic approach using turmeric and conventional Metapex^® pulpectomy in primary molars.

Materials and methods: Thirty children, in the age range of 4-9 years, with at least one primary mandibular molar indicated for pulpectomy, were included. Teeth were randomly assigned to turmeric and Metapex^® groups. For those that were assigned to turmeric, after coronal and radicular pulp extirpation, a freshly prepared paste of turmeric powder and methyl cellulose (2:1) with saline was packed in the coronal pulp chamber. In the Metapex^® group, a conventional pulpectomy was performed. Clinical and radiographic success was recorded at 3-, 6-, and 12-month follow-up visits. The data was statistically analyzed using the Chi-square test.

Results: There were no clinical and radiographic failures at 3- and 6-month visits in both groups. The 12-month evaluation revealed clinical success rates of 92% (12 out of 13) and 100% (14 out of 14) for turmeric and Metapex^®, respectively, whereas, the radiographic success rates were 85% (12 out of 13) for turmeric and 93% (13 out of 14) for Metapex^®. No statistically significant differences were found between the groups at different follow-ups (P > 0.05).

Conclusions: A modified endodontic approach using turmeric and conventional Metapex^® pulpectomy did not differ significantly in total success after 12 months.
