BACKGROUND To evaluate the effect of EDTA, Maleic acid, Citric acid and MTAD Irrigating Solutions on the shear bond Strength of A-H plus sealer. MATERIALS & METHODS Forty mandibular single rooted premolar teeth with straight roots were taken, decoronated and instrumented using Protaper rotary instruments to size #F3, 0.09 taper, at the working length, with 3 mL of 2.6% sodium hypochlorite in ...

As frequently added to adhesives, the mono-functional monomer 2-hydroxyethyl methacrylate (HEMA) acts as co-solvent and improves surface wetting. Nevertheless, HEMA promotes watersorption hydrolysis at adhesive interfaces, affecting bond durability dentin. This study investigated if two acrylamide co-monomer alternatives could replace in experimental adhesive-resin formulations part of 3/2-step...

Optimal strategies for the application of an adhesive differ between enamel and dentin because differences in their composition. The development systems has mainly focused on bonding dentin, rather than enamel, by etching with phosphoric acid (PA). Dental technologies continue to rapidly advance, various have been developed since study Buonocore 1955. He introduced acid-etch technique. Then, et...

bioactive glass air abrasion is a conservative technique to remove initial decalcified tissue and caries. this study examined the shear bond strength of composite resin to sound and decalcified enamel air-abraded by bioactive glass (bag) or alumina using etch-and-rinse and self-etch adhesives.forty-eight permanent molars were root-amputated and sectioned mesiodistally. the obtained 96 specimens...

Objective: The current study aimed to evaluate the effect of diode laser irradiation (980 nm) and warm air drying(50°C) on shear bond strength between Lithium di-silicate (IPS e.max; Ivoclar) human dentin using both(Etch & Rinse) adhesive, Adper™ Single Bond 2 (3M ESPE) (Self-etch) UniversalTM(3M before adhesive polymerization. Material Methods: 54 sound lower molars were sectioned toobtain...

OBJECTIVES This study was carried out to examine the effect of application of four different disinfecting agents on the micro-shear bond strength (μ-SBS) of an etch-and-rinse and self-etch adhesive systems. MATERIALS AND METHODS One hundred flat dentin surfaces of human molars were produced by wet grinding the buccal surfaces. Specimens were randomly assigned to five groups according to the d...
