The aim of this randomised clinical trial was to compare the clinical and radiographic success rate of 5
sodium hypochlorite (NaOCl) and 20 Formocresol (FC) as a pulpotomy medicament in carious primary molars. MATERIALS
Twenty-four children aged 4-8 years with at least 2 primary molars indicated for pulpotomy were included in
this study. Eighty-two teeth received either 5 NaOCl or 20 FC using split mouth design, followed by restoration with IRM
base/stainless steel crown (SSC). Clinical and radiographic evaluations were performed at 3, 6 and 12 months.
NaOCl and FC groups demonstrated 100 clinical success at 3 months. At 6 months, NaOCl showed 95 and 87.5 clinical
and radiographic success rate respectively, while FC showed 95 clinical and radiographic success rate. After 12 months,
the clinical and radiographic success rates were 94.6 and 86.5 respectively for NaOCl, and 92.1 and 86.8 for FC.
The results of this study showed the success rate for NaOCl pulpotomy to be comparable to those for FC
