Original Article



This study examined the effects of MTA and Biodentine on the clinical and radiographic success rates of pulpotomies performed on primary teeth with carious pulp exposures.

Materials and methods

This study was conducted with 44 mandibular primary molars requiring vital pulpotomy. Carious dentin surrounding the exposure site was used as the inclusion criteria for all teeth, which were randomly divided into two groups according to pulpotomy material [MTA group (n = 24), Biodentine group (n = 20)]. Treatment was followed up clinically and radiologically for 24 months. Pulp canal obliteration was not regarded as a failure.


Clinical and radiographic success rates at the end of 24 months were 100% for the MTA group and 89.4% for the Biodentine group. Success rates did not vary significantly between the groups (p = 0.646). Pulp canal obliteration was observed in two teeth (8.3%) in the MTA group at 6 months, but the teeth were found to be stabilized by 24 months.


The long-term clinical and radiographic success rates obtained in this study indicate that both MTA and Biodentine are appropriate options for pulpotomy treatment of primary teeth with carious exposure in patients whose teeth should be retained for long periods of time.

Clinical relevance

The etiology of exposure determines pulpal response, making it crucial to distinguish between mechanical and carious exposures. The carious exposure is presumed to be accompanied by severe inflammation, which makes the prognosis of treatment unpredictable. Biomaterials can be used especially in cases with carious pulp exposures.
