Abstract

Objectives: The adding of nanosilver particles to endodontic sealers may be affecting the push out bond strength and marginal adaptation. This study is directed to evaluate the bond strength and marginal adaptation for modified zinc oxide eugenol and resin based endodontic sealers. Methods: a total number of 120 samples were used for bond strength test and 40 samples for marginal adaptation test. Two types of endodontic sealer were used according to the type of sealer (zinc oxide eugenol sealer {Endofil} and resin sealer {Adseal}),for bond strength (n=60) and (n=20) for marginal adaptation test each group was subdivided into four subgroups (n=15) for bond strength and (n=5) for marginal adaptation test according to concentration of adding nanosilver [control, concentration A, B&C]. Each subgroup were also divided for three periods of treatment (one day, one week and one month). The push out test was done by using Instron while marginal adaptation test was done by using SEM (scanning electron microscope). T-test was used to evaluate the push out bond strength and marginal adaptation properties for the dental sealers. Results: It was found that the Adseal control subgroup had the highest value in bond strength (12.88 Mpa) and the lowest value for Endofil concentration C subgroup (0.62 Mpa). Conclusions: By increase the concentration of nanosilver particles into endodontic sealers, marginal adaptation and bond strength were significantly decreased.
