Mineral trioxide aggregate pulpotomy of a primary second molar in a patient with agenesis of the permanent successor.

AIM: To describe a pulpotomy with mineral trioxide aggregate in a primary second molar with no permanent successor.

SUMMARY: Coronal pulpotomy was performed on a carious primary molar with no permanent successor in a 7-year-old child. Follow-up examinations 24 months later revealed that the treatment was successful in preserving the tooth and the vitality of its pulp.

KEY LEARNING POINT: Mineral trioxide aggregate might be considered as an alternative wound dressing for pulpotomy in primary molars, preserving pulp vitality and prolonging the useful life of the tooth.
