Evaluation of Teeth Discoloration Induced by Endomethasone, AH+, Canason and Apexit Paste


Objective: The aim of this study was to investigate, in vitro, the color changes of the teeth, induced by endodontic sealers. Materials and Methods: Forty-five mature maxillary and mandibular anterior teeth, extracted for periodontal reasons, were collected. After the chemo-mechanical instrumentation of the root canal, teeth were filled with four endodontic sealers (Endomethason, AH+, Canason and Apexit). Depending on canal sealers and the CEJ (Cement Enamel Junction), teeth were divided into 8 experimental groups (n = 5) and one control group/CG (n = 5). Teeth color changes (L*a*b*/CIE Commission Internationaled’ Eclaraige) were determinated by a spectrophotometer Vita Easyshade in 4 stages (Baseline, Week 0, 4 and 12). Results: Between the EOCEJ and CG for the parameter L*, there was a statistical significance (p < 0.05). The L*a*b* results were: L* (82.5 ± 4.2 → 77.2 ± 1.2); a* (﹣2.38 ± 0.93 → 0.36 ± 1.41) and b* (15.5 ± 2.0 → 19.0 ± 3.2). For AOCEJ and CG there was not a statistical significance (p > 0.05). The L*a*b* results were: L* (83.6 ± 4.8 → 83.6 ± 4.9); a* (﹣2.68 ± 1.02 → ﹣1.12 ± 0.72) and b* (20.2 ± 4.5 → 24.4 ± 4.2). Conclusions: All endodontic sealers may cause teeth discoloration.
