UNLABELLED The occlusal surface is the most affected area by dental caries and the sealing of the pits and of the fissures has been found, in time, the preventive method most effective trying to counteract the onset. Currently, the WHO considers it as a primary preventive measure, in other words one of the most effective and least invasive available to ensure the complete protection and the tot...

One of the main endeavors in today’s Life Science remains the efficient sequencing of long DNA molecules. Today, most de-novo sequencing of DNA is still performed using electrophoresis-based Sanger Sequencing, based on the Sanger concept of 1977. Methods using mass spectrometry to acquire the Sanger Sequencing data are limited by short sequencing lengths of 15–25 nt. Recently, we proposed a new...

Purpose: The aim of this study was to evaluate the effects finishing and polishing (F/P) techniques on resin restorative materials’ surface roughness microhardness. Materials methods: A total 168 specimens were prepared using compomer, composite, giomer, subjected F/P. F/P performed Sof-Lex Discs, Spiral Wheels, Enamel Plus Shiny. No in control group. Surface microhardness measured. Data analyz...

ÖZET Aim: The purpose of this laboratory investigation was to evaluate the bond strength of temporary cement [(Provicem, Procem (eugenol-free), Tempbond (eugenol)] to commonly used core build-up materials. [Composite resin (President), Compomer (Dyract AP), glass-ionomer cement (Ionofil), resin modified glassionomer cement (Vitremer) (RMGIC)]. Materials and Methods: Sixty specimens were fabrica...

OBJECTIVES The aim of the study was to evaluate two ceramic materials as possible substitutes for enamel using two wear simulation methods, and to compare both methods with regard to the wear results for different materials. METHODS Flat specimens (OHSU n=6, Ivoclar n=8) of one compomer and three composite materials (Dyract AP, Tetric Ceram, Z250, experimental composite) were fabricated and s...

AIM Despite the improvements to compomer materials, the bond strength of these materials remains inferior to "composite/resin bonding" systems and limits their clinical use. The purpose of this study was to evaluate the effect of acidic conditioning with phosphoric acid and Prompt L-Pop (PLP) on the shear bond strength of two compomers Dyract AP (DAP) and Composan Glass (CG) to dentin. METHOD...

introduction: in different investigations, the destructive effect of ultrasonic scalers on the margins of composites has been studied, but there are very few studies on the effects of ultrasonic scalers on the microleakage of poly-acid modified composite resin and resin modified glass ionomers. the main purpose of this study was to evaluate the marginal microleakage of class v preparations rest...
