et al., 2001). In deep cavities, the concentration of HEMA reaching the pulp would be in the range of 1.5-8 mmol/L, and about 4 mmol/L for TEGDMA (Noda et al., 2002). Inflammatory reactions (toxic reactions) are reported after the insertion of resin-based composites and adhesives in cavities very close to the pulp or when a (micro) perforation of the pulp had occurred. Consistently, the lack of...

Current dental adhesive technology involves either an etch-and-rinse or self-etching approach.8 Evidence of clinical durability exists for both approaches, albeit depending on the specific brand.4,5 Today, enamel still requires phosphoric-acid etching and thus an etch-andrinse approach to obtain a durable bond. The adhesiveenamel bond seals the cavity and even protects the more vulnerable bond ...

OBJECTIVES This study evaluated the water sorption, solubility and kinetics of water diffusion in commercial and experimental resins that are formulated to be used as dentin and enamel bonding agents. METHODS Four commercial adhesives were selected along with their solvent-monomer combination: the bonding resins were of Adper Scotchbond Multi-Purpose (MP) and Clearfil SE Bond (SE) systems, an...

OBJECTIVES The adhesion tests utilized in dentistry are unable to separate the effects of adhesive composition, substrate properties, joint geometry and type of loading on the measured bond strength. This makes it difficult for the clinician to identify the most suitable adhesive for a given procedure and for the adhesive manufacturer to optimize its composition. Thus, an adhesion test protocol...

OBJECTIVES The aim of this study was to evaluate the bond strength of one-step adhesive systems to dry or moist dental substrate. METHODS Thirty human third molars were sectioned into two halves, in the mesio-distal direction, parallel to the long axis of the tooth. Each half was embedded in a polystyrene resin cylinder so that the buccal/lingual surface remained exposed. This exposed surface...

OBJECTIVES To evaluate the effect of double-application of all-in-one adhesives using the micro-shear bond test. METHODS The occlusal surfaces of extracted human third molars were ground perpendicular to the long axis of each tooth to expose a flat dentin surface. Three commercially available and one experimental bonding system were used in this study: Adper Prompt L-Pop (APL, 3M ESPE), REACT...

Surgical tissue adhesives continue to evolve as an important technology for the facial plastic and reconstructive surgeon. Twelve years ago there was little routine use of these substances; however, in the past 5 years there have been significant advances. It is becoming increasingly important for the facial plastic and reconstructive surgeon to be familiar with the indications and shortcomings...

AIM To evaluate the efficacy of different solvent evaporation strategies on bonding of one-step self-etch adhesives to root canal dentine. METHODOLOGY Two dual-cure resin core systems (Clearfil DC Bond/Clearfil DC Core Automix and Clearfil Tri-S Bond Plus/Clearfil DC Core Plus; Kuraray Noritake Dental, Tokyo, Japan) were equally applied in 24 post spaces from extracted human mandibular premol...
