To determine the clinical and radiographic success rates of MTA, ferric sulfate, one-fifth dilution of Buckley's formocresol, and no pulpotomy medicament except ZOE in primary molars during a 2-year follow-up period.
A randomized, single-blind, split-mouth study design of 32 healthy patients, 5-7 years old with at least 4 primary molars each in a different quadrant and similarly carious involvement so as to require a pulpotomy- 128 primary molars total. Inclusion criteria were deep caries, no more than 2/3 root resorption, restorable, and no history of systemic disease, no spontaneous tooth pain or tenderness to percussion, no pathological mobility presence of internal resorption or apical or furcal radiolucency, no widened PDL or sinus tract, or hemostasis requiring more than 5 minutes. Teeth were randomly assigned MTA, FS, FC, or ZOE and teeth were restored with amalgam; clinical and radiographic examinations were conducted after 6 months, 1 year, and 2 years.
At 6 mo and 1yr: all MTA, FS, and FC had 100% success rates
At 2yr: success rates were as follows: MTA – 96%, FS – 88%, FC – 88%, ZOE – 68%
Longer follow-up times and larger sample sizes could have revealed differences in success
