The clinical and radiographic evaluation of Allium sativum oil (garlicoil) in comparison with mineral trioxide aggregate in primary molarpulpotomy

Background: Mineral trioxide aggregate (MTA) is known as a common biomaterial for pulpotomyof primary molars, with limitation including high cost, difficult handling, and long setting time. Thisstudy was conducted to compare the clinical and radiographic success rate of Allium sativum oiland MTA in pulpotomy of primary molar teeth.Materials and Methods: This randomized, controlled, clinical trial was performed on a group ofchildren with at least two symptom‑free primary molars requiring pulpotomy. A total of 90 teethwere randomly assigned into two groups: After pulp amputation and hemostasis, Group I receivedMTA as medication in the pulp chamber and Group II received Allium sativum oil over the pulpstumps. Pulp chamber was then filled with reinforced ZOE paste (zinc oxide eugenol) and teethwere restored using stainless steel crowns.The follow‑up scheme of 6, 12, and 18 months was set,and teeth evaluation was conducted by a calibrated pediatric dentist based on the modified criteriaproposed by Zurn and Seale. The results were analyzed using the generalized estimating equationanalysis with the P = 0.05 as the level of significance.Results: The clinical success rate was 100% in both groups after all follow‑ups. The radiographicsuccess rate was, however, 91.1% after 6.75. 6% after 12 and 18 months in Group II while it was95.6% after 6, 91.1% after 12 and 18 months in Group I in those follow‑up points. The differencebetween the two groups was not statistically significant.Conclusion: According to the results,Allium sativum oil has a high clinical and radiographic successrate comparable to those of MTA.
