SUMMARY:

Sodium Hypochlorite is the most common auxiliary chemical substance used in root canal treatment that also affect the resin bond strength to dentin. Reverting this process is possible by antioxidizing agents such as Ascorbic Acid and Sodium Thiosulfate. The present study evaluated UNIVERSIDADE DE BRASÍLIA Secretaria de Pós-Graduação da Faculdade de Ciências da Saúde Programa de Pós-Graduação em Odontologia (*) Observação 1: preenchimento obrigatório para todos os examinadores internos/externos com e sem vínculo com a FUB. after 90 days the bond strength of self-adhesive resin cement in fiber post luting after irrigation of root dentin by Sodium Thiosulphate and Ascorbic Acid. A total of 92 bovine incisor roots were divided into 4 groups with different irrigation protocol. G1: irrigation with saline solution; G2: irrigation with 5% NaOCL; G3: irrigation with 5% NaOCL and 10% Ascorbic Acid; G4: irrigation with 5% NaOCL and 5% Sodium Thiosulfate. After cementing the fiberglass posts, a pull-out test was performed. The data obtained were submitted to statistical analysis using ANOVA and Post Hoc tests with a significance level of 0.05. Statistical analysis of data revealed no significant differences between Ascorbic Acid group and Sodium Thiosulfate (p > .05). After 90 days, the use of ascorbic acid or sodium thiosulfate and sodium hypochlorite solutions prior to cementing the fiberglass post has shown not to affect the adhesive strength.
