Clinical evaluation of biodentine: Its efficacy in the management of deep dental caries

ABSTRACT

Background: The advancement in the dentin regeneration aiming at the preservation of pulpal vitality has challenged the traditional concept of substituting diseased tooth with inert materials. Clinical studies, demonstrating preservation of pulpal vitality with the use of biomimetic materials in deep carious lesions, are lacking in the literature. Objective: This clinical study aims to assess the treatment outcome of vital pulp therapy using Biodentine in cases of deep carious lesion in a single visit treatment protocol. Methodology: Twelve posterior teeth with deep carious lesion with no signs of irreversible pulpitis were selected for the study. After rubber dam application, excavation of caries was performed until all infected dentin was removed leaving behind affected dentine. Biodentine was applied followed by immediate restoration with bonded composite resin. The patient was recalled at time intervals of 1 day, 1 month, 3 months, 6 months and up to 1 year for clinical and radiographic evaluation. Outcome was described in terms of success and failure. Success was defined as clinical absence of signs and symptoms, response to sensibility test on every recall visits, no tooth discoloration seen, and radiographical absence of periapical pathosis. Results: All the 12 patients were recalled at the end of 1 year for follow-up. The overall success rate was 83.4%. Two of the twelve cases required root canal treatment to relieve painful pulpitis. On clinical and radiographic examination, no signs of periapical pathosis were noted in the 10 successful cases. Conclusion: In deep carious lesions, vital pulp therapy with Biodentine has proven to maintain the pulpal vitality in permanent teeth with single visit treatment protocol.
