Introdouction: Esthetic demands of patients have led to the introduction of tooth-colored restorations wherecomposite resins are bonded to the enamel using acid etch techniques. Total etch adhesion systems are still considered as the gold standard among bonding systems. However, clinicians have a tendency to use adhesive systems with simpler application procedures. The aim of the present stu...

Background and purpose: Antibacterial properties of restorative materials are of great advantage as they control the progression of tooth decay. The use of self-adhesive composite materials has some benefits such as easier application and reduced treatment time. Because the antibacterial properties of restorative materials can play an important role in preventing secondary decay, especially in ...

The present study examined the mechanism for caries resistance and the pulp responses in vital teeth following the use of the augmented-pressure adhesive displacement technique. Dentin adhesives were applied to the surface of sound dentin disks in 4 experimental groups: non-antibacterial adhesive and gentle adhesive displacement (N-G), non-antibacterial adhesive and augmented-pressure adhesive ...

background and aims. this in vitro study evaluated the effect of delaying composite resin restorative procedures bonded with total-etch and self-etch adhesive systems on microleakage following root canal irrigation with sodium hypochlorite (naocl) solution. materials and methods. the roofs of pulp chambers and roots (1–2 mm below furcation) of 40 human first molar teeth were cut and pulp tissue...

introduction: this study investigated the sealing ability of three different adhesives in primary bovine teeth. methods: facial and lingual class v cavities were prepared half in enamel and half in cementum, in 48 bovine primary mandibular incisors and randomly divided into three groups and each group divided to two subgroups. the tested adhesives were xpbond (xp), clearfils3 bond (s3), and xen...

introduction: retention of fiber reinforced composite posts depends on the bond strength between post and cement, and cement and root dentin. the aim of this study is to evaluate the bond strength of one type of fiber post to radicular dentin with different adhesive cements. materials and methods: crowns of 44 caries-free, human premolar were removed 2 mm below the cej and the roots were endodo...

We have investigated the effectiveness and safety of a newly developed biological adhesive for repair of meniscal tear. The adhesive was composed of disuccinimidyl tartrate (DST) as a crosslinker and human serum albumin (HSA) as a hardener. To determine adequate concentration, bonding strength was measured using a tensiometer 5 min after applying the adhesive on the avascular zone tear of porci...

the effect of nanoparticle diamond incorporated in an experimental dental adhesive formulation is valuated by examining the mechanical properties and shear bond strength of the system. diamond nanoparticles were incorporated into the dentin adhesive system in different concentrations of 0, 0.05, 0.1, 0.2, 0.5, and 1.0 weight percentages. the suspensions were ultrasonicated to facilitate the nan...

background: at the end of fi xed orthodontic treatment, the remnant of adhesive should be eliminated from the tooth surface. the purpose of this study was to compare the effect of three methods of removing adhesive on enamel surface roughness, dental pulp t emperature, and also on the time spent. materials and methods: the brackets on 90 extracted teeth were debonded using bracket removal plier...
