ABSTRACT
PURPOSE:
To determine whether there were differences between formocresol (FC) and white mineral trioxide aggregate (MTA) pulpotomy in terms of clinical and radiographic signs or effects upon the permanent successor over a long term.METHODS:
A total of 212 molars (74 treated with FC and 138 with white MTA) corresponding to 129 subjects [66 females (51.1%) and 63 males (48.8%)] were evaluated. The coronal pulp was carefully amputated up to the entrance of the root canals using a sharp spoon excavator. Post-amputation bleeding was confirmed to be bright red and was seen to subside after applying 2-3 minutes of gentle pressure with a sterile cotton pellet. One group was treated with a 15 dilution of formocresol (20% Buckley's formocresol solution), while a second group was treated using white MTA powder (ProRoot).RESULTS:
There were no significant differences in clinical success rate between the two groups (89.9% in the white MTA group versus 82.5% if the FC group). However, the radiographic success rate was significantly greater for white MTA versus FC. The radiographic failure rate in the molars treated with MTA was 7.9% versus 18.9% with FC. Regarding alterations in the timing of eruption, early and delayed eruption were respectively recorded in 7.24% and 8.69% of the cases in the MTA group, versus 9.45% and 4.05% of the cases in the FC group. Thus, neither group showed relevant alterations in the timing of eruption. CLINICALSIGNIFICANCE:
Mineral trioxide aggregate showed a significantly greater radiographic success rate than formocresol in pulpotomy in primary teeth over 6 to 48 months of follow-up. MTA may be indicated as a substitute of formocresol in pulpotomy treatments of temporary molars, with no pathological consequences of any kind to the permanent successor premolar.
