Purpose:
To evaluate the long-term clinical and radiographical results of using gray mineral trioxide aggregate (MTA) in pulpotomy treatments in primary molars.
Methods:
A total of 69 primary molars were treated with pulpotomy procedures using MTA and follow-up every 6 months up to 42 months.
Results:
Clinical success was 100% as none of the molars showed clinical pathologic signs; radiographical success was 98.5% as one case of internal resorption was recorded. Reparative dentin deposition was found as stenosis of the pulp canals in 84% of the cases 42 months after treatment and as dentin bridge formation in 83% of the cases 42 months after treatment. Moreover, 11 permanent successors erupted at their normal exfoliation time without pathology after pulpotomy treatment with gray MTA of the primary molars.
