Comparative evaluation of the biological response of conventional and resin modified glass ionomer cement on human cells: a systematic review.

Unlabelled: This review aimed to evaluate and compare the biological response (biocompatibility and cytotoxicity) of resin modified glass ionomer cement (RMGIC) in contrast to conventional glass ionomer cement (GIC) on human cells. Articles reporting parallel and split-mouth clinical trials, randomized controlled trials, non-randomized controlled trials, prospective studies, and studies on human permanent teeth that assessed the biological response of GIC and RMGIC were included. The following electronic bibliographic databases were searched using the keywords: MEDLINE/PubMed, EBSCO, Cochrane Central Register of Controlled Trials, and Google Scholar.

An comparative evaluation of efficiency of three rotary nickel-titanium file systems in terms of remaining dentin thickness using cone-beam computed tomography.

Aim: The objective of the present research was to assess and compare the residual dentin thickness after biomechanical preparation of teeth using three distinct rotary nickel-titanium (Ni-Ti) file systems.

Materials And Methods: In the current experimental study, a total of 45 single-rooted teeth were selected for the analysis. The cementoenamel junction of each tooth was decoronated using a diamond disc.
