This in vitro study evaluated the effect of air-drying time on degree of solvent evaporation (DE), dentin microtensile bond strength (µTBS), and degree of conversion (DC) of 5 adhesive systems: Adper Single Bond 2, XP Bond, Prime & Bond 2.1, OptiBond Solo, and Adper Easy One. For DE testing, 20 µL of each material was submitted to measurements in a digital balance after an air stream of 3, 5, 1...
مقدمه:.هدف از مطالعه کنونی، بررسی استحکام باند ریز برشی دو نوع یونیورسال باند به عاج سطحی و الگوهای شکست به دو طریق سلف اچ و توتال اچ بود. مواد و روشها: عاج سطحی 35 دندان پرمولر سالم کشیده شده بوسیله دیسک اکسپوز شد و سپس از هر دندان دوقطعه بدست آمد. سپس نمونه ها بطور تصادفی به 5 گروه مساوی تقسیم شدند <st...
To evaluate the effect of erosive challenges on the tooth- restoration interface of deciduous teeth treated with different adhesive protocols. Deciduous molars were cut mesiodistally, then embedded, abraded and polished (n=80). Samples were randomly divided according to the adhesive system used into: G1 (Adper Single Bond2®, etch-and-rinse), G2 (Universal Single Bond®, self-etching), G3 (Optibo...
Background and Objective: Microleakage is the most important reason for secondary caries and treatment failure. The aim of this study was to evaluate the effect of liner (flowable composite) and bonding agents on microleakage of resin composite (z250) in class II cavities. Materials and Methods: Standardized Class II cavities were prepared on mesial and distal of 80 human premolars. The teet...
the purpose of this study was to investigate the relationship between teachers’ class management practices with students’ self- regulated learning and academic self-efficacy. in this study relating to the management class, three dimensions, (training management, people management and behavior management) and three style (interventionist, interactionist and non-interventionist) was considered. r...
BACKGROUND The objective of this study was to investigate the influence of Er,Cr:YSGG laser irradiated at different powers on the micromorphology and the bonding property of non-carious sclerotic dentin to resin composites. METHODS Two hundred bovine incisors characterized by non-carious sclerotic dentin were selected, and the seventy-two teeth of which for surface morphological analysis were...
Objective The purpose of this study was to investigate the effect of silver nanoparticles on composite shear bond strength using one etch and rinse and one self-etch adhesive systems. Material and Methods Silver nanoparticles were prepared. Transmission electron microscope and X-ray diffraction were used to characterize the structure of the particles. Nanoparticles were applied on exposed den...
This study evaluated the shear bond strengths of orthodontic brackets bonded to human premolars using five different combinations of flowable composites and one-step self-etching adhesives (n=12): (1) Adper Easy Bond+Filtek Supreme XT Flow; (2) Futurabond NR+Grandio Flow; (3) Clearfil S3 Bond+Clearfil Majesty Flow; (4) AdheSE One+Tetric EvoFlow; and (5) Transbond Plus Self Etching Primer+Transb...
