Postoperative Pain After Root Canal Obturation With Sealer Containing Prednisolone.

Postoperative Pain Evaluation After Definitive Root Canal Obturation With Zinc Oxide/Eugenol-type Sealer Containing or Not 1% Prednisolone Acetate - Steroid Anti-inflammatory Agent: a Comparative, Randomized Clinical Trial.

The study design is a multicentric randomized controlled clinical trial. 238 subjects (teeth) requiring a primary or a secondary root canal treatment will be enrolled in 2 groups (119 in each group).

The aim is to assess the effectiveness and utility of the ancillary drug substance, prednisolone acetate (1%) contained in CORTISOMOL SP (Zinc Oxide/Eugenol-type sealer) to help to decrease the possible postoperative painful reactions after root canal treatment. SEALITE REGULAR, which has a similar formulation except it is prednisolone acetate-free, is used as the comparator sealer.

Procedures of root canal treatment will be conventional and standardized for all investigational centers. The canals will be cleaned, shaped and then obturated using a Zinc oxide/Eugenol-type sealer (CORTISOMOL SP or SEALITE REGULAR) and gutta-percha.

Patients assess their pain for 7 days after permanent root canal obturation.
