Dental and composite resin discoloration induced by different hydraulic calcium silicate-based cements: two-year in vitro assessment

Abstract: Few long-term studies assess the discoloration induced by hydraulic calcium silicate-based cement on dental structures. In addition, as far as we know, no long-term study has assessed the discoloration induced by these cement on composite resin. Objective This in vitro study aimed to assess, during a period of two years, the discoloration potential of different hydraulic calcium silicate-based cements (hCSCs) on the enamel/dentin structure and composite resi… Show more

“…With the recording of initial L*a*b* data, tooth color reference values were also determined based on the VITA Classical shade guide and the VITA 3D Master scale guide. To ensure uniformity and prevent discrepancies both within and among the groups, the teeth were distributed evenly across the experimental groups: 4 teeth with an A2 shade, 2 teeth with a B2 shade, and 4 teeth with an A3 shade [ 7 , 17 ].…”

“…Nevertheless, in approximately 40% of RET cases, discoloration is observed due to the interaction between the blood clot—which is crucial for natural scaffold formation in the apical region—and the applied MTA [ 4 , 5 , 6 ]. The reasons for this tooth discoloration include not only blood–MTA contact but also the destabilization of bismuth oxide in contact with sodium hypochlorite [ 7 ]. These unacceptable color changes after dental treatments cause the treatment to be evaluated as esthetically unsuccessful.…”
