Objectives: To evaluate and compare clinical and radiographic success of the selective removal to soft dentine technique in one step using calcium silicate cement (Biodentine) vs. no indirect pulp capping material in patients with deep caries lesions in mature permanent posterior teeth with normal or reversible pulpitis after a 2 year follow-up. Evaluate the integrity of the resin composite restorations using FDI criteria.

Material and methods: selective removal to soft dentine in one visit will be performed in 104 blinded patients that will be randomly allocated into 2 study arms, 52 patients will constitute the Biodentine group and 52 the No material group. Clinical examination will be performed to obtain pre-, intra- and postoperative data, including vitality test results, periapical status and risk of caries of the patients. Periapical and bitewing radiographs will be taken before treatment (T-0), at 1 month (T-1), 6 months (T-2), 12 months (T-3) and 24 months (T-4). Restorations will be assessed using the FDI criteria at the same follow up periods.
