This in vitro spectrophotometric study aimed to investigate the tooth discolouration potential of Well Root ST, MTA Fill apex and Dia-Proseal root canal sealers. The crowns of sixty human maxillary central and lateral incisor teeth were sectioned and coronal pulps were removed. Pulp chambers were filled with selected root canal sealer except the control group (n = 15). The colour changes were determined using spectrophotometer at prior to filling, 1 week after filling, after 1 month and after 3 months. One-way ANOVA and Bonferroni post hoc tests were used for data analysis. All sealers caused clinically perceptible discolouration after 1 month showing significant differences from the control group (P < 0.05). There was no statistically significant difference among Well Root ST, Dia-Proseal and MTA Fill apex root canal sealers (P > 0.05). Within the limitations of this study our data indicate Well Root ST, Dia-Proseal and MTA Fill apex induce a similar amount of perceptible tooth discolouration.
