HIỆU QUẢ TẠO NGÀ SỬA CHỮA CỦA XI MĂNG CALCIUM SILICATE (BIODENTINETM) TRONG ỨNG DỤNG CHE TUỶ GIÁN TIẾP

Abstract

Objective: Evaluation of the effect of calcium silicate cement (Biodentine^TM) on reparative dentinogenesis following indirect pulp capping. Methods: A 20-year-old female patient presented the pain in tooth number 37 when eating or cold/hot drinking, occurring several times over the previous one month. Based on the clinical and radiographic examinations, tooth was diagnosed with reversible pulpitis. The tooth was anaesthetized before placement rubber dam for isolation. Decayed tissues were removed using a sterilized high-speed round bur under water coolant. The cavity was disinfected by a sterile cotton pellet soaked in 2,5% sodium hypochlorite before capping with Biodentine^TM. The tooth was finally restored with resin composite after one month. Clinical and radiographic evaluation was completed at 6 months and 1 year postoperatively. Results: The patient reported the mild pain occurred for the first post treatment day, but pain was soon alleviated. After 6 months and one year, the patient had no complaint about the tooth, positive responses to cold and electric pulp tests, and periapical radiographs showed the formation of reparative dentin underlying the cavity, no periapical lesion. Conclusions: Biodentine^TM can be an optimal option for indirect pulp capping and is able to induce the reparative dentinogenesis.
