Efficacy of Removal of Residual Dental Cement by Laser, Ultrasonic Scalers, and Titanium Curette: An In Vitro Study.

The purpose of this study was to conduct an in vitro evaluation of the efficacy of six dental lasers, two ultrasonic scalers, and a titanium curette in the removal of dental cement from the surface of an implant. The study used a total of 39 dental implants, representing three different surface textures. The implants were divided into 13 groups with one of each of the three surface textures in a group.

The fatty acid signaling molecule cis-2-decenoic acid increases metabolic activity and reverts persister cells to an antimicrobial-susceptible state.

Persister cells, which are tolerant to antimicrobials, contribute to biofilm recalcitrance to therapeutic agents. In turn, the ability to kill persister cells is believed to significantly improve efforts in eradicating biofilm-related, chronic infections. While much research has focused on elucidating the mechanism(s) by which persister cells form, little is known about the mechanism or factors that enable persister cells to revert to an active and susceptible state.
