AB - Mineral trioxide aggregate have been used for many years as a pulp therapy material. The most widely used product, Proroot white MTA has a major drawback that it causes tooth discoloration.
This study assessed discoloration of crown when various MTA-based materials were placed in the coronal aspect of the root canal.
Seventy-five single-rooted, unrestored premolar teeth were selected. The teeth were randomly assigned to four experimental groups, each of Biodentine, Proroot wMTA, Endocem, RetroMTA and one negative control groups. Color measurements were utilized by the Commission International de I’Eclairage’s L*a*b* system with spectrophotometer. The color was assessed eight times : initial, 1 day, 1 week, 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 16 weeks after the placement. Statistical analysis was performed using the 2-way repeated analysis of variance and Bonferroni’s method with p < 0.05.
Proroot wMTA induced significant decreases in L* values during experiment period. Tooth samples from the Endocem group presented indistinct grayish color changes. The Biodentine and RetroMTA showed color stability.
Consequently, while Proroot wMTA and Endocem that contain bismuth oxide as a radiopacifier showed tooth discoloration, displayed no sign of discoloration Biodentine and RetroMTA that contain zirconium oxide as a radiopacifier.
