| Abstract | ||||
| Objectives: The adding of nanosilver particles to endodontic sealers may be considered a method to improve the antibacterial properties. This study is directed to evaluate the antibacterial properties for modified zinc oxide eugenol and resin based endodontic sealers. Methods: a total number of 72 samples were used. They were divided into two main groups (n=36) according to the type of endodontic sealer (zinc oxide eugenol sealer {Endofil} and resin sealer {Adseal}), each group was subdivided into four subgroups (n=9) 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 antibacterial test was done by using CLSM (confocal scanning microscope). T-test was used to evaluate the antibacterial properties for the dental sealers. Results: It was found that the Endofil concentration C had the highest value in antibacterial activity (0.75 volumes of dead cells) and the lowest value for Adseal control group (0.16 volumes of dead cells). Conclusions: By increase the concentration of nanosilver particles into endodontic sealers, the antibacterial activity was significantly increased. | ||||
