Comparative evaluation of the effect of nitrofurantoin and triple antibiotic paste on the push-out bond strength of epoxy resin sealer: An study.

CONTEXT

Following chemomechanical preparation, the application of intracanal medicaments is recommended to further decrease the microbial count. To combat endodontic infections, the application of antibiotics as intracanal medicaments has been an option for years in endodontics.

AIM

The aim of this study was to compare and evaluate the effect of antibiotic pastes on the push-out bond strength (POBS) of resin-based root canal sealer.

MATERIALS AND METHODS

Forty-eight extracted single-rooted teeth were used after decoronation to a standardized root length of 15 mm. Canals were enlarged up to size F3 using Protaper rotary instruments. Samples were randomly divided into three groups according to the intracanal medicament used. Group A: Nitrofurantoin (NIT) Paste, Group B: Triple antibiotic paste (TAP), and Group C: Control group (without intracanal dressing). After removal of the medicament (endoactivator), obturation was done with AH Plus sealer. Push-out bond strength was calculated using universal testing machine.

STATISTICAL ANALYSIS

Data were analyzed using one-way ANOVA followed by Tukey and Kruskal-Wallis test (with a significance level of < 0.05).

RESULTS

Compared to the control group, the POBS significantly increased after using intracanal medicaments with < 0.05 (The results showed that the mean bond strength of TAP was highest, closely followed by NIT and least with the control group).

CONCLUSION

Under the limitations of this study, it can be concluded that the use of TAP and NIT increases the POBS of the Epoxy Resin Sealer.
