Abstract:
To evaluate the staining susceptibility of new calcium aluminate cement ( E ndo B inder, EB ) in teeth, with or without radiopacifying agent, in comparison with mineral trioxide aggregate ( MTA ). Materials and methods Forty bovine incisors were used. After biomechanical preparation and filling, 2 mm of their fillings were removed for cervical plug fabrication ( n = 10): EB without radiopacifier; E ndo B inder + B ismuth O xide ( EBBO ); Gray mineral trioxide aggregate ( GMTA ) and White mineral trioxide aggregate ( WMTA ). After teeth restoration, initial color readout was taken (Easyshade – CIE L ab) on the vestibular face. The teeth were stored in artificial saliva at 37°C for 1 year, and after time intervals of 30, 180, and 360 days, new color readouts were taken to determine color alteration (Δ E ) in comparison with the initial readout (baseline). Results The results (2‐way anova repeated measures, B onferroni – P 〈 0.05) demonstrated that after 360 days, all groups presented Δ E above the clinically accepted limit (Δ E ≥ 3.3), however, without significant difference among them ( P 〉 0.05). All groups presented decrease in Δ L values over the course of time, and the greatest variation occurred for WMTA , with significant difference in comparison with EB and EBBO ( P 〈 0.05). Conclusions Some negative features of MTA , such as the high incidence of dental structures staining justify the development of new materials. GMTA , WMTA , and EB with and without radiopacifying agent displayed color alteration (Δ E ) after 360 days; however, the luminosity change (Δ L ) was lower in EB in comparison with GMTA and WMTA .
