Dental cements were used in conventional crown restorations for many decades before being utilized in cement-retained restorations in order to make a connection between the implant body and the crown. Cementation is the preferred restoration method because it eliminates unaesthetic components, aids in the obtainment of correct loading characteristics, and is usually less expensive than screw-retained counterparts. However, the use of dental cements has been a constant source of apprehension due to multiple reports indicating in vitro and in vivo cytotoxicity, and their ability to be contaminated by the oral microbiota. Because of this, residual dental cement is listed as a risk factor for peri-implant disease by the American Academy of Periodontology. Furthermore, since there is not a standard guiding dental cement selection, many clinicians approach it in a subjective manner. It has been established that cement selection is done base on preference, ease of use, and current trends on conventional restorations. Cement selection is further complicated by the lack of cements manufactured specifically for implant restorations. Current approaches for dental cement selection could, therefore, neglect the use of cement compositions that could aid in the success of the restoration. The goal of this study was to evaluate the biocompatibility and antimicrobial effects of various commercial dental cements in order to emphasize the impact dental cement composition can have in the oral environment.
