ĐÁNH GIÁ ĐAU SAU ĐIỀU TRỊ CHE TỦY TRỰC TIẾP BẰNG BIODENTINETM TRÊN RĂNG CỐI LỚN

Abstract

Background: Direct pulp capping (DPC) is a conservative treatment designed to preserve pulp vitality, yet its success depends greatly on the material employed. Biodentine™, a calcium silicate-based cement with superior biocompatibility and dentin-bridge inducing properties, has been increasingly recommended as an alternative to calcium hydroxide and mineral trioxide aggregate (MTA). However, clinical data on its postoperative pain outcomes remain scarce in Vietnam, particularly in molars where treatment prognosis is often more complex. Objective: To assess the characteristics of postoperative pain in permanent molars treated with direct pulp capping using Biodentine™. Methods: This clinical study included 26 permanent molars from 24 patients, monitored over a 3-month period. Pain intensity was assessed at baseline, 1 day, 7 days, 1 month, and 3 months after treatment using the Visual Analog Scale (VAS) in combination with clinical examinations, including percussion and pulp vitality tests. Results: At baseline, most patients presented with mild thermal sensitivity. One day after DPC, 80.8% of cases still reported mild to moderate pain, though transient and not requiring analgesics. By 7 days, 80.8% of teeth were pain-free, and after 3 months, all treated molars showed complete absence of pain. No case progressed to irreversible pulpitis or periapical pathology during the follow-up period. Conclusion: Biodentine™ provided effective and early pain control following direct pulp capping in molars, with symptoms decreasing rapidly and resolving entirely by 3 months. These findings highlight its favorable biological compatibility and support Biodentine™ as a reliable material for clinical pulp preservation, especially in permanent molars.
