Objective To evaluate coronal tooth discoloration of ProRoot MTA, white ProRoot MTA, EndoSequence Root Repair Material, MTA-Angelus, and Biodentine when used in an ex-vivopulpotomy model. Methods Freshly extracted mandibular third molars were collected and stored in 1Chloramine-T solution. Teeth were randomly assigned into 6 groups N15 and stored individually in phosphate-buffered saline at 37C in 100 humidity. A standardized endodontic access was made in 5groups. A 3mm-thick increment of reparative material was placed on the pulpal floor, covered by glass ionomer, and restored with composite. Color CIE Lab was recorded with the Vita Easy Shade spectrophotometer on the mid-buccal surface at baseline, and after access preparation, material placement, 1, 7, 30, and 60 days.
