Abstract
Design
This was a randomised controlled trial.
Intervention
The trial assessed application of formocresol (FC) or mineral trioxide aggregate (MTA) during pulpotomy in primary molar teeth.
Outcome measure
Treatment was evaluated by recording clinical signs (spontaneous pain, swelling, pain on palpation or percussion and sinus tract formation) or radiological signs of failure (root resorption, periodontal ligament widening, and apical, lateral or furcal radiolucency).
Results
No signs of clinical failure were observed at 3 and 6 months but, at the 6-month follow-up, significantly more cases (P 0.036) with root resorption were seen in the FC group. No cases of resorption occurred in the MTA group. The surrounding tissue showed radiographical signs of post-treatment disease in four FC-group members; none was seen with MTA use.
Conclusions
After 6 months, pulpotomy with MTA was associated with fewer cases of root resorption and post-treatment disease. MTA appears to be a reliable alternative material for pulpotomy in primary molar teeth.
