Abstract

Aim:The aim of this study is to evaluate the coronal tooth discoloration caused by the materials used in such applications, by using spectrofotometre. Material and Methods:Fifty extracted human maxillary central incisor teeth were used in this study. Teeth were randomly assigned into 5 groups (n = 10) and stored in saline solution at 37 °C in 100% humidity. Apical part of the root, was removed 2 mm below the semento-enamel junction. Then apical access cavity was made in 5 groups and prepared by using Gates Glidden files (Dentsply, Maillefer, USA) at number 1 to 6. The groups were as follows: Negative control group, Biodentin, Bioaggregate, ProRoot MTA and Positive control group (bovine animal blood). A 2mm-thick increment of reparative material was placed on the pulpal floor, covered by glass ionomer cement. Color change was evaluated with Easyshade Advance Spectrophotometer at 5 time points: day 0 (T0), day7 (T1), day 14 (T2), 1 month (T3) and 2 months (T4). Changes in Commission Internationale de l'eclairage L*a*b* were measured for each experimental group and compared with each other. Results: There were no significant differences between negative control group, biodentin and bioaggregate group. These groups produced significantly less discoloration than ProRoot MTA and positive control group. There were significant drops in the values of L* from T0 to T4 in the Positive control group and ProRoot MTA group. The values decreased over time as the samples became darker.. Conclusions: Tricalcium Silicate based materials such as Biodentine or Bioaggregate can be prefer instead of MTA in the anterior teeth, where the esthetic outcome is very important.
