Cold plasma: a novel approach to treat infected dentin-a combined ex vivo and in vitro study.

Objectives: The aim of this study was to evaluate the antimicrobial effect of cold plasma (CP) on infected dentin surfaces in vitro and ex vivo.

Materials And Methods: To examine the effect of cold plasma on root surfaces, 24 root surfaces were infected with Streptococcus mitis. Specimens were randomly divided into three groups: Within the control group (C), root surfaces were rinsed with NaCl; root surfaces in the second group were additionally scaled and root planed (SRP), and in the third group, root surfaces were rinsed, scaled, root planed, and in addition, CP was applied (SRP + CP).

Bactericidal efficacy of tissue tolerable plasma on microrough titanium dental implants: An in-vitro-study.

Surface decontamination remains challenging in peri-implant infection therapy. To investigate the bactericidal efficacy of tissue tolerable plasma, S. mitis biofilms were created in vitro on 32 microrough titanium dental implants.

Bactericidal Efficacy of Cold Plasma at Different Depths of Infected Root Canals In Vitro.

Objectives: Cold plasma (CP) has been shown to be effective even against multiresistant microorganisms. As previous investigations on the effect of CP in root canals showed promising results, the aim of the present study was to analyze the bactericidal efficacy of CP in different depths of infected dentin.

Methods: 32 standardized root canals of human mandibular premolars were infected with Enterococcus faecalis and incubated for one week.
