| Abstract | Aims: The aim of this study was to evaluate the specific chromatic alterations in tooth crowns induced by two different endodontic restorative materials. Settings and Design: This in vitro study was conducted at the Department of Conservative Dentistry, KMCT Dental College, Kozhikode, Kerala. Subjects and Methods: Forty-five freshly extracted, fully developed, single-rooted teeth were prepared and randomly assigned to two experimental groups (n = 15 each) and one negative control group (n = 15). Group 1 consists of white mineral trioxide aggregate (WMTA), Biodentine formed Group 2, and controls formed Group 3. Double-beam ultraviolet spectrophotometer equipment was used to assess the coronal discoloration as determined by CIE L*, a*, and b* and their corresponding total values. Results: At baseline, no significant difference was detected for CIE values between the groups. Group 1 showed a significant decrease in L*, a*, and b* values over time. The color change with WMTA led to clinically perceptible crown discoloration after 6 weeks which exceeded the perceptible threshold for the human eye, i.e., ΔE > 3.3. No changes were observed with Biodentine. Conclusions: Materials used in endodontics may stain teeth. WMTA induced clinically perceptible crown discoloration, whereas Biodentine demonstrated color stability. |
