Background: Maintaining the pulpally involved deciduous teeth in a healthy state until the time of normal exfoliation remains to be one of the challenges for pedodontics. Several materials have become popular as pulpotomy medicaments. Success rate of FC pulpotomy has been 70-97% in the last decades. Concerns have been raised about the toxicity, potential carcinogenicity, cytotoxicity, allergenicity, systemic disturbances, and the possibility of affecting the permanent successors. It seems that the efficacy of MTA is superior to FC which is the gold standard in pulpotomy of deciduous teeth. Aim of the study: To compare Formocresol vs MTA in deciduous teeth treatment. Materials and methods: The study was performed on 50 deciduous molars of 40 child patients with age ranging between 5-9 years. The caries were removed from the surface of tooth after administering local anesthesia. An access cavity to pulp was made using high speed round but with water spray. Coronal pulp was amputated using a low-speed sterile round bur (No = #6 or No = #8) with water spray, and hemorrhaging was controlled using sterile saline blotted sterile pellets. The patients were recalled for clinical and radiographic examination after 6, 12, 18, 24, and 30 months, and examinations and success rate were determined. Results: It was observed that MTA had better success rate as compared to Formocresol for all follow up time lines. Similarly, radiographic success rate was better observed with MTA in comparison to formocresol. Conclusion: Within the limitations of the present study, it can be concluded that Formocresol and MTA have fair success rate for treatment in deciduous teeth, however, the success rate of MTA is better than Formocresol. Further studies are required.
