Over the past century, synthetic adhesives have largely displaced their natural counterparts in medical applications. However, rising concerns over the environmental and toxicological effects of the solvents, monomers, and additives used in synthetic adhesives have recently led the scientific community to seek natural substitutes. Marine mussel adhesive protein is a formaldehyde-free natural ad...

Background: Cyanoacrylate tissue adhesives have been used as a substitute to silk for intraoral wound closure. Placement of sutures provides a corridor for accumulation of microorganisms into tissue which leads to infection. Cyanoacrylate-based adhesives exhibit many properties of an ideal wound closure agent, minimizing the problems generated by suturing thread. The antimicrobial properties of...

When placing an indirect restoration such as a porcelain veneer, inlay, or onlay, the intaglio surface is typically treated in some fashion to ensure optimal bonding to the resin-based adhesives and luting cements required to affix it to the tooth tissues. A variety of surface preparation techniques have been advocated, including the use of acids, particle abrasion, various adhesives, and chemi...

BACKGROUND Currently, several systems of dentin substrate-reacting adhesives are available for use in the restorative treatment against caries. However, the bond effectiveness and property of different adhesive systems to caries-affected dentin are not fully understood. The objective of this study was to evaluate the bond strength of different adhesives to both normal dentin (ND) and caries-aff...

OBJECTIVES This study evaluated the effect of three different air-drying times on microleakage of three self-etch adhesive systems. MATERIALS AND METHODS Class I cavities were prepared for 108 extracted sound human premolars. The teeth were divided into three main groups based on three different adhesives: Opti Bond All in One (OBAO), Clearfil S(3) Bond (CSB), Bond Force (BF). Each main group...

Precision assembly of hybrid micro systems requires not only a high precision handling and adjusting of the parts but also a highly accurate and fast bonding technique. In this field adhesive technology is one of the major joining techniques. At the Collaboration Research Center 516, a batch process based on a joining technique using hot melt adhesives was developed. This technique allows the c...

background and aims. the aim of this study was to evaluate the antibacterial activity of one-step self-etch adhesives on enterococcus faecalis on days 1, 7 and 14 with the use of modified direct contact test. materials and methods. the modified direct contact test was used to evaluate the antibacterial effect of adper easy one, bond force, clearfil s3 bond, futurabond m, g-bond, ibond and optib...

Background: Fibrin-based biological adhesives are used for tissue adhesion improving the outcome of gastrointestinal sutures. The objective was to assess the effectiveness of fibrin-based biological adhesives for prevention of anastomotic leakage in high-risk gastrointestinal anastomoses. Methods: A randomized clinical trial was designed to recruit patients underwent a rectal resection surgery....
