Pulpotomy In Primary Teeth Using Two Different Application Times Of Ferric Sulfate.
Pak J Orthodont Ped and Comm Dentistry Jan ;1(2):96-9.

This study was undertaken to evaluate the success rate of ferric sulfate pulpotomy using two different application periods and to compare the findings with those of previous studies of ferric sulfate pulpotomies and those using formocresol. Eighty-two carious exposed primary molars of thirty-one children aged 3.5-9.5 years (mean = 6 years, 8 months) were conventionally pulpotomized. Teeth were divided randomly into two groups. In group I (n=39 molars), ferric sulfate was applied for 15seconds. In group II (n=43 molars), ferric sulfate was applied for 30 seconds. All pulp stumps were covered with ZOE, sealed with IRM, and restored using stainless-steel crowns. Clinical and radiographic evaluations were performed at 3, 6, and 9month intervals. The overall clinical success rate was 100% in both groups. The overall radiographic success rate was 75.8% in group I and 96% in group 11. Statistical analysis revealed a significant difference (P=0.039) between the two application times. It was concluded that the effect of ferric sulfate could be time-related and that more favorable results can be obtained with a 30-second application as compared with 15-second application.
