Biofilm formation of C. albicans on occlusal device materials and antibiofilm effects of chitosan and eugenol.

Statement Of Problem: Microbial adhesion on occlusal devices may lead to oral diseases such as candidiasis. Whether chitosan and eugenol provide antibiofilm effects is unclear.

Purpose: The purpose of this in vitro study was to evaluate the biofilm formation of C.

3D-2D microleakage assessment of preheated bulk-fill composite resin applied with different parameters: a micro-CT analysis.

This study evaluated microleakage from class II cavities filled with bulk-fill composite preheated to different temperatures, applied at different thicknesses, and with different polymerization modes. A total of 60 mesio-occlusal cavity were drilled into the extracted human third molars at 2 mm and 4 mm thickness. Preheated bulk-fill composite resin (Viscalor; VOCO, Germany) was applied to the cavities at 68 °C and 37 °C after the adhesive resin was applied, and cured using standard and high-power light-curing modes of a VALO light-curing unit.

Effect of different polishing techniques on surface properties and bacterial adhesion on resin-ceramic CAD/CAM materials.

Objectives: The aim of this study is to evaluate the adhesion of Streptococcus mutans on the surface of CAD/CAM materials with various surface treatments.

Methods: Vita Enamic, Lava Ultimate, and Cerasmart materials were used in this study. A total of 90 samples were prepared (n = 10).

Evaluation of color stability and microhardness of contemporary bulk-fill composite resins with different polymerization properties.

Objectives: To determine the color stability and microhardness of three bulk-fill composites with different polymerization characteristics, after immersion in four different solutions.

Materials And Methods: Color measurements of three bulk fill (Viscalor (VIS), Tetric PowerFill (TPF), Fill Up! (FUP)) and a microhyrid composite resin (G-aenial posterior [GCP]) were performed after polymerization. The specimens were immersed in coffee, cola, red wine and distilled water.

Evaluation of surface characteristic and bacterial adhesion of low-shrinkage resin composites.

This study aimed to examine the surface characteristics of low shrinkage composites and adhesion of Streptococcus mutans and Streptococcus mitis to these materials. Control material (glass) and three low shrinkage composites (Charisma Diamond, Kalore GC, Beatiful II LS) were used. After polishing procedure was applied to composite specimens, surface roughness (SR), surface free energy (SFE), and contact angle measurements were performed.
