The investigator performed a prospective longitudinal randomized controlled study of 60 vital permanent teeth with deep caries from 50 patients. Patients were divided randomly into Biodentine™ and MTA groups; patients with more than one offending tooth were treated with both Biodentine™ and MTA. Teeth were assessed clinically and radiographically prior to the procedure. Caries were excavated under local anesthesia, hemostasis was achieved after pulp exposure using NaOCl and capped with Biodentine™ or MTA. Clinical and radiographical follow-up were performed by a blinded calibrated evaluator after six months and one year
