Efficacy of titanium dioxide nanoparticle spray to disinfect mobile phones used by endodontist: A bacteriological study.

Aim: The objectives of this study were to determine the bacterial contamination of the mobile phones that were used by the endodontist in comparison with the general dentist and also to determine the usefulness of titanium dioxide nanospray (TiO NS) in mobile phone decontamination.

Materials And Methods: Samples from the 60 mobile phones were taken using moist sterile swabs before, 10 min, and 1 week after the use of TiO NS. Before collection of the swabs, the participants' informed consent was obtained.

Effectiveness of N-acetyl cysteine, 2% chlorhexidine, and their combination as intracanal medicaments on Enterococcus faecalis biofilm.

Aim: The purpose of this study was to evaluate the antibacterial efficacies of 2% chlorhexidine (CHX), N-acetyl cysteine (NAC) and assess their synergistic or antagonist action as intracanal medicament.

Materials And Methods: Agar diffusion test was performed with 2% CHX, NAC, and their combination against E. faecalis planktonic cells.
