“…However, a high concentration of HEMA in self-etch adhesives may compromise the mechanical properties of the cured adhesive. HEMA also lowers the vapor pressure of solvents; therefore, large amounts may hinder good solvent evaporation from adhesive solutions (82). There is an optimum concentration of HEMA that improves the bonding efficacy of self-etch adhesives.…”

Improvements in dentin bonding systems have influenced modern restorative dentistry. The desire for minimal invasiveness has resulted in moreconservative cavity design, which basically relies on the effectiveness of current dentin bonding systems. Interaction of adhesives with enamel and dentin is based on two systems, commonly described as etchand-rinse and self-etch. Priming and bonding agents can be separate or combined, resulting in two-or three-step systems for etch-and-rinse adhesives and one-or two-step systems for self-etch adhesives. Selfetch systems use acidic functional monomers that simultaneously demineralize and impregnate tooth structures. Etch-and-rinse and self-etch systems have advantages and disadvantages, which are primarily related to the simplified bonding procedures required under clinical conditions. Knowledge of the composition, characteristics, and mechanisms of adhesion for each adhesive system is critical in selecting the ideal adhesive materials for clinical use. (J Oral Sci 56, 1-9, 2014)

“…Plakları kaplamada kullandı-ğımız HEMA monomerinin test ettiğimiz gram negatif bakterilerin biyofilm oluşumunu %88.8 oranında inhibe ettiği saptanmıştır. HEMA biyokimyasal ve mekanik karakteristiğinden ötürü özellikle diş hekimliğinde, dental restoratif materyaller içerisinde kullanılan ana komponentlerden biridir (29) . HEMA monomerinin streptokok türlerinde biyofilm oluşumu üzerine etkisini inceleyen bir çalışmada, biyofilm oluşumu-na direk etkisi bulunamamış, fakat artan kon-santrasyonların planktonik hücre miktarının düşürerek biyofilm formasyonunu indirek olarak azalttığı gözlemlenmiştir (30) .…”

“…The solvent evaporation before the photoactivation of an adhesive system is regarded as being of paramount importance to increase the effectiveness of the bonding procedure 6,9 . The adhesive system is placed and exposed while it is in a liquid state and is relatively low in viscosity.…”

“…For a durable, long-term sealing of dentin, monomers must be converted to stable high-molecular-weight polymers 20 . The residual water or organic solvents is claimed to be responsible for producing localized areas of incomplete monomer polymerization 6,7,9 . Thus, the monomer conversion and the extent of polymerization might vary throughout the hybrid layer, which could cause significant differences in the quality of the interpenetrating network at different locations 13 .…”

ObjectiveTo evaluate the influence of solvent evaporation in the kinetics of water diffusion (water sorption-WS, solubility-SL, and net water uptake) and nanoleakage of adhesive systems. Material and MethodsDisk-shaped specimens (5.0 mm in diameter x 0.8 mm in thickness) were produced (N=48) using the adhesives: Clearfil S3 Bond (CS3)/Kuraray, Clearfil SE Bond - control group (CSE)/Kuraray, Optibond Solo Plus (OS)/Kerr and Scotchbond Universal Adhesive (SBU)/3M ESPE. The solvents were either evaporated for 30 s or not evaporated (N=24/per group), and then photoactivated for 80 s (550 mW/cm2). After desiccation, the specimens were weighed and stored in distilled water (N=12) or mineral oil (N=12) to evaluate the water diffusion over a 7-day period. Net water uptake (%) was also calculated as the sum of WS and SL. Data were submitted to 3-way ANOVA/Tukey's test (α=5%). The nanoleakage expression in three additional specimens per group was also evaluated after ammoniacal silver impregnation after 7 days of water storage under SEM. ResultsStatistical analysis revealed that only the factor "adhesive" was significant (p<0.05). Solvent evaporation had no influence in the WS and SL of the adhesives. CSE (control) presented significantly lower net uptake (5.4%). The nanoleakage was enhanced by the presence of solvent in the adhesives. ConclusionsAlthough the evaporation has no effect in the kinetics of water diffusion, the nanoleakage expression of the adhesives tested increases when the solvents are not evaporated.

Influences of surface and solvent on retention of HEMA/mixture components after evaporation

Abstract: The rate of solvent evaporation and its retention into HEMA/solvent primers was influenced by the type of the solvent and condition allowed for their evaporation.
