statement of problem: the bond strength between restorative material and tooth structure is so important for conduction of durable restoration. considering the recent attention to low shrinkage composite resins, evaluation of micro tensile bond strength of these materials would be valuable. objectives: to compare the microtensile bond strength of silorane composite resin (filtek p90) with the c...

OBJECTIVES The purpose of this study was to evaluate dentin and enamel bond strength to resin composite following high-speed rotary or Er:YAG laser preparation using a total etch adhesive system. The microstructure of resin-tooth interfaces was also investigated. METHODS Human dentin and enamel specimens were prepared with a high-speed handpiece (KaVo) or Er:YAG laser (DELight) at manufacture...

background: antioxidizing agents have recently been suggested to compensate decreased bond strength of resin materials to bleached tooth tissues. this study compared the shear bond strength (sbs) of three different adhesives on bleached dentin immediately after bleaching, bleached/delayed for 1 week, and bleached/applied antioxidizing agent. materials and methods: the dentinal surfaces of 132 i...

The purpose of this in vitro study was to evaluate the efficacy of three hydrophilic dentin adhesive systems to reduce class II restoration microleakage. A total of 60 human molar teeth were used in which two box cavities were made on the distal and mesial surfaces, with a cervical margin in dentin. These cavities were randomly divided into 3 groups (n = 40 each), according to adhesive system t...

background: the aim of this study was to determine the microtensile bond strength (μtbs) of ceramic and composite computer aided design‑computer aided manufacturing (cad‑cam) blocks bonded to dentin using different adhesive strategies. materials and methods: in this in vitro study, 30 crowns of sound freshly extracted human molars were sectioned horizontally 3 mm above the cementoenamel junctio...

OBJECTIVE The purpose of this study was to evaluate the influence of Er:YAG laser irradiation on the bond strength to dentine of three single-step adhesives (AQ Bond Plus, G-Bond, and Clearfil Tri-S Bond), and one two-step self-etch adhesive (Clearfil Megabond) as a control. BACKGROUND DATA The vast majority of the numerous reports on resin bonding to Er:YAG-lased dentine have concluded that ...

The purpose of this study was to evaluate the dentin shear bond strength of four adhesive systems (Adper Single Bond 2, Adper Prompt L-Pop, Magic Bond DE and Self Etch Bond) in regards to buccal and lingual surfaces and dentin depth. Forty extracted third molars had roots removed and crowns bisected in the mesiodistal direction. The buccal and lingual surfaces were fixed in a PVC/acrylic resin ...

BACKGROUND To investigate pulp response to the application of two types adhesive systems (total-etch and self-etch) in human premolar teeth. MATERIALS AND METHODS Cavities limited to enamel walls in all margins with 2.5 mm depth were prepared on buccal surfaces of thirty three human premolars. The cavities were treated with the following adhesive. Single Bond (SB) and Prompt L-Pop (PLP). The ...

Methods: The labial surfaces of 28 bovine mandibular incisors were wet ground to achieve a flat enamel or dentin surface. A 1-step self-etch adhesive and a 3-step etch-and-rinse adhesive were bonded to enamel or dentin according to the manufacturer’s instructions (Adper Easy One and Adper Scotchbond, respectively). A composite resin cylinder (Filtek Z350 XT) was built upon the adhesive layer us...
