statement of problem: chemo-mechanical caries removal is an effective alternative to the traditional rotary drilling method. one of the factors that can influence micro-leakage is the method of caries removal. objectives: to compare the micro-leakage of resin composite in primary dentition using self-etch and all-in one adhesives following conventional and chemo-mechanical caries removal. mater...

The aim of this investigation was to compare the microleakage of composite resin (Z-100) and shear bond strength to bovine dentin using different types of adhesive systems (Scotch Bond Multi-Purpose, All-Bond 2, One-Step, and Perma Quick) to compare and correlate microleakage to shear bond strength. For the microleakage aspect of the study, 20 class V were prepared (bovine incisors) with 90-deg...

statement of problem: recently, it has been proposed that different adhesive materials can be used for direct pulp capping. previous studies have demonstrated that multi steps dentin adhesives could form reparative dentin similar to calcium hydroxide (ch). purpose: the aim of this study was to evaluate the histological pulp response of ninety mechanically exposed cat pulps to two adhesive resin...

Scotch Whisky is an important product, both culturally and economically. Chemically, Scotch Whisky is a complex mixture, which comprises thousands of compounds, the nature of which are largely unknown. Here, we present a thorough overview of the chemistry of Scotch Whisky as observed by Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). Eighty-five whiskies, representing t...

The aim of this study was to evaluate the shear bond strength of resin composite repairs with and without aging of the surface to be repaired, using different adhesive systems and resin composites. Ninety specimens were prepared: 10 for the Control Group (GC - without repair); 40 for Group I (GI - repairs after 7 days) and 40 for Group II (GII - repairs after 180 days). Groups I and II were div...

OBJECTIVES Dentin Bonding Agents (DBAs) have been proposed as root-end filling materials. This study examined the effect of polymerized DBAs on human monocyte viability. STUDY DESIGN Monocytes were directly isolated from peripheral blood and being exposed to cured Scotch bond I (Single Bond) and Prime & Bond in different time intervals (36 and 72 hours). The viability of monocytes was determi...
