BACKGROUND The aim of the present study was to evaluate the influence of water storage on micro tensile strength (µTS) and mass changes (MC) of two universal adhesives. MATERIAL AND METHODS 10 disk-shaped specimens were prepared for each adhesive; Scotchbond Universal (SCU) All-Bond Universal (ABU) and Adper Single Bond 2 (SB2). At the baseline and after 1 day and 28 days of water storage, th...

This study was conducted to examine the shear bond strengths of orthodontic brackets to ground enamel with two self-etching adhesives (Beauty Ortho Bond and Transbond XT) and two phosphoric acid-etching adhesives (Kurasper F and Orthomite Superbond). After the bonded specimens were stored in water at 37 degreees C for 24 hours, they were subjected to thermal cycling (TC) at 0 and 5000 cycles. T...

An adhesive that functions well under moist conditions could facilitate many surgical procedures. In recent studies we designed novel biomimetic glues which mimic the adhesion mechanism of algae, renowned for their remarkable adherence to wet surfaces. Here we extend our previous studies and propose biomimetic formulations, composed of alginate gel and native phloroglucinol, that do not induce ...

North American porcupines are well known for their specialized hairs, or quills that feature microscopic backward-facing deployable barbs that are used in self-defense. Herein we show that the natural quill's geometry enables easy penetration and high tissue adhesion where the barbs specifically contribute to adhesion and unexpectedly, dramatically reduce the force required to penetrate tissue....

Cyanoacrylates have been recognized since before the 1960s as excellent tissue adhesives. They are easy to use, cost-effective, and cosmetically favorable. There are no studies from India reporting the use of tissue adhesives in laparoscopic surgery. We carried out a prospective, interventional, randomized trial of non-absorbable simple interrupted sutures versus 2-octyl cyanoacrylate in the cl...

Secreted anterior adhesives, used for temporary attachment to epithelial surfaces of fishes (skin and gills) by some monogenean (platyhelminth) parasites have been partially characterised. Adhesive is composed of protein. Amino acid composition has been determined for seven monopisthocotylean monogeneans. Six of these belong to the Monocotylidae and one species, Entobdella soleae (van Beneden e...

Isocyanate-terminated adhesive amphiphilic block copolymers are attractive materials to treat meniscus tears due to their tuneable mechanical properties and good adhesive characteristics. However, a drawback of this class of materials is their relatively long curing time. In this study, we evaluate the use of an amine cross-linker and addition of catalysts as two strategies to accelerate the cu...

BACKGROUND Wound closure devices include sutures, tissue adhesives, adhesive strips, and staples. Recent studies suggest no differences between various tissue adhesives and sutures for dehiscence, infection, and satisfaction when assessed by patients or surgeons. To date, no studies have investigated ClozeX, a novel adhesive strip, for closure of surgical incisions. OBJECTIVE To compare surgi...

Purpose: To compare the biocompatibility of ethyl-cyanoacrylate (ECA) and octylcyanoacrylate (OCA) wound closures to sutures in rat skin. Methods: Twenty-four male Wistar rats were subjected to three incisions which were closed using ECA, OCA or sutures . Rats were divided into four groups which received biopsies on the 3rd, 7th, 14th or 21st postoperative days. Necrosis, inflammation, dermatit...
