Pulpotomy in Carious Permanent Mature Teeth: Pulp Survival and Risk Factors

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03490422
Recruitment Status : Completed
First Posted : April 6, 2018
Last Update Posted : April 6, 2018

Dr Victoria Yu, National University Health System, Singapore

Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Pulpitis Pulp Exposure, Dental Pulp and Periapical Tissue Disease Procedure: Pulpotomy Not Applicable

Detailed 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.
