About

This Trial evaluated the extent of pulp survival following pulpotomy in the permanent tooth pulp exposed by caries and identify potential risk factors for pulpal complications.

Full description

Healthy patients ≥ 21 years old were recruited with informed consent. Inclusion criteria were symptomatic and asymptomatic periodontally sound teeth, positive response to pulp sensibility tests, pulp exposure by caries with bleeding, haemostasis achieved within 10 minutes and normal apical tissues. Under local anaesthesia and rubber dam isolation, caries was removed before pulpotomy. Pain complaint, clinical and radiographic data were collected during recalls for up to 3 years.
