Ethanol-wet bonding and chlorhexidine improve resin-dentin bond durability: quantitative analysis using raman spectroscopy.

Purpose: To directly test the effectiveness of ethanol-wet bonding (EW) in improving monomer infiltration into demineralized dentin through quantitative measurement of bis-GMA and TEG-DMA molar concentrations within hybrid layers, and to comprehensively evaluate the effect of EW and chlorhexidine on durability of resin-dentin bonds compared to conventional water-wet bonding (WW).

Materials And Methods: A three-step etch-and-rinse adhesive (70% bis-GMA/28.75%TEG-DMA) was applied to coronal dentin using a clinically relevant ethanol-wet bonding protocol (EW) or the conventional water-wet bonding (WW) technique.

Ceramic materials for porcelain veneers: part II. Effect of material, shade, and thickness on translucency.

Statement Of Problem: Information regarding the differences in translucency among new ceramic systems is lacking.

Purpose: The purpose of this study was to compare the relative translucency of the different types of ceramic systems indicated for porcelain veneers and to evaluate the effect of shade and thickness on translucency.

Material And Methods: Disk specimens 13 mm in diameter and 0.

Ceramic materials for porcelain veneers. Part I: Correlation between translucency parameters and contrast ratio.

Statement Of Problem: Different parameters are used in the literature to describe translucency, making it difficult for clinicians to find clear information on ceramic translucency and compare studies.

Purpose: The purpose of this study was to assess the correlation between the contrast ratio (CR) and translucency parameter (TP) when the translucency of different types of ceramic systems is compared.

Material And Methods: Disks 13 mm in diameter and 0.

Effect of polishing direction on the marginal adaptation of composite resin restorations.

Problem: Polishing composite resin restorations may lead to marginal defects and gap formation.

Purpose: To assess the effect of polishing direction on the marginal adaptation of composite resin restorations using two composite resins and two polishing systems.

Materials And Methods: Forty extracted human molars were sectioned along their mesio-distal axis.

Consumers' choice of dentists: how and why people choose dental school faculty members as their oral health care providers.

This study aimed to better understand how and why people choose dental school faculty members as their oral health care providers. Increasing financial constraints in U.S.

Development and evaluation of an interactive dental video game to teach dentin bonding.

Written and clinical tests compared the change in clinical knowledge and practical clinical skill of first-year dental students watching a clinical video recording of the three-step etch-and-rinse resin bonding system to those using an interactive dental video game teaching the same procedure. The research design was a randomized controlled trial with eighty first-year dental students enrolled in the preclinical operative dentistry course. Students' change in knowledge was measured through written examination using a pre-test and a post-test, as well as clinical tests in the form of a benchtop shear bond strength test.
