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.
