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...

In the tough, competitive environment of international ice hockey, it is vital that a player who sustains a minor facial laceration is returned to play as soon as possible. A method of wound closure that is fast to apply, water resistant, and effective was sought. Dermabond, a cyanoacrylate tissue adhesive, was selected for use during the 2002 International Ice Hockey Federation World Champions...

OBJECTIVES Polymerized dental resin materials release residual monomers that may interact with pulp tissues. We hypothesized that dental adhesives might cause cytotoxicity in pulp cells via the generation of reactive oxygen species (ROS), which may also contribute to genotoxic effects in vitro. METHODS For cytotoxicity testing, transformed human pulp-derived cells were exposed to extracts of ...

BACKGROUND After thoracic surgery, adhesions between the pleura can cause substantial complications. This study investigated the effectiveness of a novel membrane utilizing surface water induction technology to prevent adhesions. METHODS Eight beagles were divided into an experimental group (five males) and a control group (three females). The experimental group underwent thoracotomy on both ...

The use of denture adhesives is common among denture wearers, and it is also prescribed by many dentists. Prescribing denture adhesives has been viewed by many prosthodontists as a means of compensating for any defects in the fabrication procedures. Denture adhesives add to the retention and thereby improve chewing ability, reduce any instability, provide comfort and eliminate the accumulation ...

Tissue adhesives play an important role in surgery to close wounds, seal tissues, and stop bleeding, but existing adhesives are costly, cytotoxic, or bond weakly to tissue. Inspired by the water-resistant adhesion of plant-derived tannins, we herein report a new family of bioadhesives derived from a facile, one-step Michael addition of tannic acid and gelatin under oxidizing conditions and cros...

There are many advantages that polymeric adhesives can offer compared to the more traditional methods of joining such as bolting, brazing, welding, mechanical fasteners, etc. and epoxy adhesives represent the most common type of structural adhesive. When polymerised, epoxy adhesives are amorphous and highly-crosslinked materials and this microstructure results in many useful properties for stru...

Sticking plasters revolutionized the protection of minor wounds, but they’re not ideal for fragile skin. A material that mimics the adhesive properties of certain beetles’ feet might provide a solution. Adhesives that stick to skin for long periods of time, or over multiple cycles of use, are vital for medical applications. Such materials have to conform to stringent standards — for example, th...
