简要总结

The optimal treatment of deep caries lesions extended to the inner third of dentin is still under discussion. Cariologists prefer selective caries removal, meanwhile endodontists recommend partial pulpotomy. So far, no clinical trial compared both interventions against each other. Additionally, current literature indicates alternative treatment options for irreversible pulpitis besides conventional orthograde root canal treatments like the partial or full pulpotomy. Existing clinical studies on this topic were using different clinical protocols, especially with regards to the accepted time to achieve hemostasis. It is still unclear, if the pulpal bleeding time prior to the capping procedure affects the outcome of partial or full pulpotomy.

详细描述

Goals of the study

In consequence, the investigators aim to proof the effectiveness of different therapies and protocols in two study arms, depending on the initial diagnosis:

Arm A: Randomized-controlled clinical non-inferiority trial:

Teeth with reversible pulpitis will be included accordingly to the inclusion criteria (see below). After randomization, teeth will be treated either with selective caries removal (indirect pulp capping) or partial pulpotomy pursuant to the below described clinical protocol. The intention of this study arm is to evaluate both therapies.

Arm B: Prospective non-controlled clinical intervention trial

盲法说明

Every patient has to give informed consent for participating in one of both study arms. To avoid clustering, only one tooth per patient can be included. Arm A is designed as a randomized-controlled and arm B as a non-controlled intervention trial.

The intervention in study arm B will be conducted adapted to the clinical findings after entering slightly the pulp chamber. Depending on the pulpal bleeding time, either a partial pulpotomy or a full pulpotomy will be conducted, according to the predefined protocol mentioned in "treatment protocol for arm A". Due to the experimental design, only single blinding of the patient is feasible.
