purpose: to present our experience with cyanoacrylate tissue adhesive in eyes with exposed hydroxyapatite orbital implants. methods: cyanoacrylate tissue adhesive was used in 3 patients with hydroxyapatite orbital implant exposure defects. results: cyanoacrylate glue was applied on the defective area of 3 patients presenting with small exposure (<4mm). the patients were followed for 33 months (...

Inspired by the remarkable adhesive capabilities to wet surfaces of the secretes of the brown alga Fucus serratus, novel glues have been designed and characterized. Formulations composed of phloroglucinol, alginate, and calcium ions are capable of adhering to a variety of surfaces. Rheological data show that the presence of phloroglucinol lowers the amount of Ca(2+) ions required for sol-gel tr...

We present a new manufacturing technology to produce multi-scale compliant feet for use with a novel climbing robot. Climbing robots for space exploration missions may allow scientists to explore environments too difficult for traditional wheeled designs. These climbing robot designs should be able to grasp or adhere to a variety of surface types at multiple angles in order to be effective. To ...

BACKGROUND There are different solvents presented in simplified adhesives. Bond-1 SF has been developed, which contains neither water nor organic solvents, in order to eliminate technical issues in terms of evaporation of solvents and concerns for the durability of resin-dentin bond. Thus this study was conducted to evaluate the microtensile bond strength (?TBS) of solvent-free and ethanol-base...

Abstract This paper addresses strengths, weaknesses, opportunities, and threats of the wood adhesives industry as discussed at International Conference on Wood Adhesives in May 2022. The authors have organized points made during discussion added further facts, assumptions, conclusions to provide context perspective, even surpassing outcome discussion. biggest themes were unprecedented opportuni...

OBJECTIVES The objectives of this study were to synthesize two new siloxane-methacrylate (SM) monomers for application in dentin adhesives and to investigate the influence of different functionality of the siloxane-containing monomers on the adhesive photopolymerization, water sorption, and mechanical properties. METHODS Two siloxane-methacrylate monomers (SM1 and SM2) with four and eight met...

OBJECTIVE This study evaluated marginal integrity of bonded posterior resin composite fillings to enamel and dentine with and without 4mm flowable base, before and after thermo-mechanical loading (TML). METHODS 80 MOD cavities with one proximal box beneath the CEJ were prepared in extracted human third molars. Direct resin composite restorations (SDR with CeramX mono, Tetric EvoCeram, Filtek ...

Purpose: The purpose of this study was to determine the initial viscosity and adhesive strength of commercial denture adhesives and oral moisturizers. Materials and Methods: Four cream-type denture adhesives, one gel-type denture adhesive and three gel-type oral moisturizers were used in the study. The initial viscosity was measured using a controlled-stress CarriMed CSL500 rheometer. The adhes...

Adhesion to wet and dynamic surfaces, including biological tissues, is important in many fields but has proven to be extremely challenging. Existing adhesives are cytotoxic, adhere weakly to tissues, or cannot be used in wet environments. We report a bioinspired design for adhesives consisting of two layers: an adhesive surface and a dissipative matrix. The former adheres to the substrate by el...

This study examined the immediate bond strength of etch-and-rinse adhesives to demineralized dentin saturated with either water or absolute ethanol. The research hypothesis was that there would be no difference in bond strength to dentin between water or ethanol wet-bonding techniques. The medium dentin of 20 third molars was exposed (n = 5). The dentin surface was then acid-etched, left moist ...
