MMP-9 Expression in Permanent Mature Teeth With Symptomatic Pulpitis

Coronal pulpotomy was performed with a sterile high-speed round bur under water coolant. Pulp vitality was confirmed by the presence of bleeding pulp tissue from all of the canal orifices. Hemostasis was achieved through the application of a pellet moistened with 2.5% NaOCl for two minutes and was repeated as needed. Calcium-silicate based material was prepared ac-cording to the manufacturer's instructions and gently placed over the pulp to fill the entire cavity.
