Abstract :

Aim: We evaluated the degree of crown discoloration induced by two different antibiotic pastes. Methodology: Ninety–five extracted human incisors were prepared to size #30. After pulp tissue removal, shaping and irrigation procedures, the specimens were randomly divided into two groups (n=45), which received either triple antibiotic paste or minocycline paste as intracanal medicament. In five teeth calcium hydroxide was used as a control group. Spectrophotometric readings were obtained on the buccal surfaces of the crowns on day 0 to week 4 after dressing, and the differences in color were recorded. Data were analysed with the Mann–Whitney U and Wilcoxon sign tests (P < 0.05). Results: Both groups showed statistically significant coronal discoloration from day 0 to weeks 1, 2, 3 and 4 (P < 0.01), but their final shades did not significantly differ between the groups (P > 0.05). Conclusions: Both antibiotic pastes induced crown discoloration, and neither was superior.
