A histopathological comparison of pulpal response to formocresol and sodium hypochlorite used as pulpotomy medicaments: In primary teeth - A clinical trialA histopathological comparison of pulpal response to formocresol and sodium hypochlorite used as pulpotomy medicaments: In primary teeth - A clinical trial.

AIM: The aim of the study was to evaluate and compare formocresol (FC) and 5% Sodium hypochlorite (NaOCl) as pulpotomy medicaments and to assess the histological features of both pulpotomy medicaments in primary teeth. MATERIALS AND METHODS: In the present study, pulpotomies were performed on 60 primary molars in 55 children aged 5-8 years. The teeth were divided into two groups NaOCl and FC were placed on the canal orifices, respectively, and crowns were restored with intermediate restorative material and glass ionomer cement. The teeth were underwent a histopathological procedure and extracted after 6 months. The Histological samples were evaluated in relation to odontoblastic integrity, pulp calcification, dentin bridge formation, and presence of pulp stone. RESULTS: No statistically significant difference was found between the two groups with respect to inflammatory response, soft-tissue organization, and dentin bridge formation (P > 0.005). CONCLUSION: Based on the results of this study Sodium hypochlorite may be a suitable medicament for conducting pulpotomy in primary teeth.
