Abstract

PURPOSE

The purpose of this study was to evaluate the total success rates of mineral trioxide aggregate (MTA), ferric sulfate (FS), and formocresol (FC) as pulpotomy agents in primary molars.

METHODS

A randomized, split-mouth study design was used in 32 healthy 5- to 7-year-old children with 128 carious primary molars without clinical or radiographic evidence of pulp degeneration. The pulpotomy agents were assigned as follows: Group 1=MTA; Group 2=FS; Group 3=1:5 diluted Buckley's FC; and Group 4=zinc oxide eugenol (ZOE) base. Clinical and radiographic follow-up at 6, 12, and 24 months used the following criteria: pain; swelling; sinus tract; mobility; internal root resorption; and furcation and/or periapical bone destruction. The data were analyzed using chi-square.

RESULTS

No significant differences in success rates were found among the groups at 6 and 12 months. Success rates in groups 1 to 4 at 24 months were 96%, 88%, 88%, and 68% respectively. There was a significant difference (P<.001) between the MTA and ZOE groups at 24 months.

CONCLUSIONS

ZOE, as the only pulpotomy medicament, had a significantly lower success rate than MTA. No significant differences were observed, among the 3 experimental materials (MTA, FC, and FS) at 2 years follow-up.
