Bactericidal and Biocompatible Properties of Plasma Chemical Oxidized Titanium (TiOB) with Antimicrobial Surface Functionalization.

Coating of plasma chemical oxidized titanium (TiOB) with gentamicin-tannic acid (TiOB gta) has proven to be efficient in preventing bacterial colonization of implants. However, in times of increasing antibiotic resistance, the development of alternative antimicrobial functionalization strategies is of major interest. Therefore, the aim of the present study is to evaluate the antibacterial and biocompatible properties of TiOB functionalized with silver nanoparticles (TiOB SiOx Ag) and ionic zinc (TiOB Zn).

Study of energy transfer by different light curing units into a class III restoration as a function of tilt angle and distance, using a MARC Patient Simulator (PS).

Objective: The MARC Patient Simulator (MARC PS) enables researchers to observe the influence of handling errors on the radiant exposure that is delivered by light curing units (LCUs). Changes in the tilt angle and distance of the light guide exit face in relation to the surface of the composite increment have a distinct effect on the total amount of light delivered during polymerization and may cause insufficient conversion of the material. Therefore, the aim of the present study was to determine the influence of the tilt angle and distance of irradiance on the efficiency of light application by recording the total amount of energy using the anterior tooth sensor of the MARC PS.

Antibacterial photodynamic treatment of periodontopathogenic bacteria with indocyanine green and near-infrared laser light enhanced by Trolox(TM).

Background And Objectives: It has been shown that certain vitamins can significantly enhance the effect of photodynamic anti-tumor therapy. Unfortunately, there is no sufficient information available about the impact of those antioxidants on antimicrobial Photodynamic Therapy (aPDT). The present study is aimed at investigating the antimicrobial effect of the dye indocyanine green (ICG) in the presence of Trolox(TM) , a vitamin E analogue, upon irradiation with near-infrared (NIR) laser light (808 nm) on the gramnegative periodontopathogenic bacteria Aggregatibacter actinomycetemcomitans (A.

Photodynamic antimicrobial effect of safranine O on an ex vivo periodontal biofilm.

Background And Objective: The increasing resistance of oral pathogens against antibiotic measures urgently requires new therapeutic strategies. In this context, antimicrobial photodynamic therapy (aPDT) may play a crucial part in the future. The aim of the present study was to compare the antibacterial efficiency of aPDT using the photosensitizer safranine O with that of chlorhexidine (0.
