This study evaluates the clinical and radiographic outcomes of direct pulp capping using Biodentine (Septodont, Saint-Maur-des-Fossés, France), a calcium silicate-based cement, in mature permanent teeth diagnosed with reversible pulpitis following carious or mechanical pulp exposure. Biodentine was placed as a full-thickness (bulk) capping and interim restoration, with a definitive composite restoration completed at a later visit. Pulp vitality, postoperative pain, and radiographic healing are assessed over a 6-month follow-up period.
Mature permanent teeth clinically diagnosed with reversible pulpitis and presenting vital pulp exposure (carious or mechanical) were treated with direct pulp capping. After caries removal under rubber dam isolation, haemostasis of the exposed pulp was achieved with 2.5% sodium hypochlorite. Biodentine (Septodont, Saint-Maur-des-Fossés, France), a calcium silicate-based cement, was then placed as a full-thickness (bulk) direct pulp capping material, filling the cavity and serving as an interim restoration. At a subsequent visit (approximately 2 to 6 weeks later), the superficial layer of Biodentine was reduced and a definitive composite restoration was placed. Participants were followed clinically and radiographically at 1 week, 1 month, 3 months, and 6 months to assess pulp vitality, symptoms, and periapical status, including dentin bridge formation.

After caries removal under rubber dam isolation, haemostasis of the exposed vital pulp was achieved with 2.5% sodium hypochlorite. Biodentine (Septodont, Saint-Maur-des-Fossés, France), a calcium silicate-based cement, was mixed and placed directly over the pulp exposure as a full-thickness (bulk) capping and interim restoration. At a subsequent visit (approximately 2 to 6 weeks later), the superficial Biodentine layer was reduced and a definitive composite restoration was placed.

Overall treatment success
Number of teeth with overall treatment success, defined as meeting both clinical and radiographic success criteria simultaneously. Clinical success: no spontaneous or lingering pain, negative percussion test, normal peri-radicular soft tissue (no swelling or sinus tract), positive response to pulp sensibility testing (transient cold response and electric pulp test within normal limits), and no abnormal tooth discoloration. Radiographic success: normal peri-radicular structures with continuous lamina dura and non-widened periodontal ligament space, no new periapical radiolucency, no internal or external root resorption, and stable pulp chamber and canal morphology. Reported as the number of teeth meeting the success criteria.
Time frame: 3 months, and 6 months
Postoperative pain intensity
Postoperative pain intensity measured using the Visual Analogue Scale (VAS), a 0 to 10 scale where 0 indicates no pain and 10 indicates the worst imaginable pain (higher scores indicate a worse outcome).
Time frame: 24 hours, day 2-7, week 2-4, 3 months, and 6 months
Pulp vitality (sensibility response)
Number of teeth retaining pulp vitality, defined as a positive response to pulp sensibility testing (cold test and/or electric pulp test). Reported as the number of teeth with a positive sensibility response.
Time frame: Baseline, 1 month, 3 months, and 6 months
