Translucent fiber post cementation using a light-curing adhesive/composite system: SEM analysis and pull-out test.

摘要: Summary Objectives. The performance of both light-curing and dual-cured adhesive/luting systems (as control), when used in combination with translucent fibre posts, was evaluated by means pull-out test scanning electron microscopy (SEM ) observation. Methods. Forty root canal treated teeth were randomly divided into two groups 20 specimens each. Group 1 system: Excite Tetric Flow; 2 dual cured All Bond 2+RelyX ARC. Translucent, double taper posts (2.1/1.4 mm diameter). stored NaCl 0.9% solution at 37 °C. A week later, the carried out on all specimens. Ten tested for each group their corresponding processed SEM Statistical analysis performed applying one-way variance (ANOVA) followed T-test as post-hoc comparison a significance level set p Results. There is no statistically significant difference (p>0.05) between system (275.2±58.9 N) one (301.4±40.1 N). observations confirm good bond dentine post whatever curing method employed. Conclusions. Dual ARC seems to be most appropriate since it allows cure even those areas which would not otherwise reached light. On other hand, apical areas, incomplete Excite+Tetric Flow could improve adaptation allow achievement an improved seal more distribution stress along walls.
