| Popis: | Aim To assess the antimicrobial efficacy of Silver diamine fluoride (SDF), Sodium hypochlorite (NaOCl), Chlorhexidine (CHX) and Photodynamic therapy (PDT) in radicular dentin and subsequent bond strength of Fiber reinforced composite post (FRCP) to radicular dentin. Material and methods Forty extracted premolars were disinfected and decoronated up-to cement-o-enamel junction (CEJ). Canals were instrumented using crown-down technique, dried and filled with gutta percha. Post space was prepared with the help of peso reamers and inoculated with E. faecalis. Samples were randomly allocated into four groups based on chemical irrigation (n = 10). Group 1, canal disinfected with (PDT, MB), group 2 (5.25 % NaOCl +17 % EDTA), group 3 (3.8 % SDF) and group 4 (CHX). Specimens were tested with confocal laser scanning microscopy analysis (CLSM) to confirm the presence of E. faecalis. Fibre post were luted in root canal and sectioned at three levels (apical, middle and coronal). Push-out test was performed and failure analysis of debonded surfaces was evaluated using stereomicroscope. Live and dead cells after exposure were calculated in percentage. One-way analysis of variance (ANOVA) assessed the means and standard deviations of extrusion bond strength (EBS). Tukey multiple comparison tests was used to compare means of bond strength (p = 0.05). Results The maximum antimicrobial efficacy against E. faecalis was observed in group 2 which included canal disinfected with 5.25 % NaOCl and 17 % EDTA (64.41 ± 1.22). Similarly, CHX showed lowest effectiveness as canal irrigant against E.faecalis (58.29 ± 2.41). Intragroup comparison revealed highest bond strength for group 2 at all three level. Similarly, the lowest EBS was found in CHX group. Inter-group comparison confirmed comparable EBS at all root levels (apical, middle and coronal) for group 2 and group 3 (p > 0.05). Conclusion Radicular dentin treated with 5.25 % NaOCl and 17 % EDTA displayed highest antimicrobial and bond strength scores. SDF and PDT can potentially be used in canal irrigation. |
