The aim of this study was to evaluate the shear bond strength of bracket composites as a function of the application of flow adhesive prior to the composite and light curing time. Material and methods: Freshly extracted bovine permanent central incisors (50) were acid etched and divided into four groups varying the attachment protocol: (1) no adhesive, composite light-cured for 20s; (2) no adhe...

statement of problem: following the increasing use of composites in restoring anterior and posterior teeth, problems due to its technique sensitivity have become a major concern. one of these problems is the possibility of contamination of dentin with saliva, blood and/or gingival fluid in different stages of bonding procedure, even with application of different methods of isolation. however, b...

The purpose of this study was to evaluate the influence of environmental temperature, humidity and methods to dry the etched enamel surface on the adhesive strength of dental adhesive resin Panavia EX '. The findings were as follows 1. Though temperature and humidity in oral cavity were higher than 30•Ž and 81% respectively, they were significantly different from site to site. 2. By rubber dam ...

in production of tissue paper, the adhesion of a liquid adhesive creping aid, compound polymer, as creping aids on the yankee dryer surface was investigated. a compound polymer was prepared based on mixing ratio of poly (amideamine)-epichlorohydrin resin (pae) as an adhesive agent, polyvinyl alcohol (pva) as a modifier agent, and cationic fatty acid (cfa) and ethylene glycol (eg) as release age...

Despite the biodegradability, non-toxicity, and renewability, commercially available soy protein-based adhesives still have not been widely adopted by industry, partially due to their disappointing performances, i.e., low glue strength in the dry state and no glue strength in the wet state. In this study, biomimetic soy protein/CaCO(3) hybrid wood glue was devised and an attempt made to improve...

In this study, a novel 5-Fluorouracil (5-FU) enema with good bio adhesion and temperature sensitivity was developed using in situ gelling technology. The preparation was formulated as a free-flowing liquid before use, while a layer of gel film was quickly formed when administered in the rectum, with a large contact surface area. It also demonstrated good biocompatibility, appropriate gel streng...

Objectives Bonding of fiber posts to intracanal dentin is challenging in the clinical setting. This study aimed to compare the effect of self-adhesive and separate etch adhesive dual cure resin cements on the bond strength of fiber post to dentin at different parts of the root. Materials and Methods This in-vitro experimental study was conducted on 20 single-rooted premolars. The teeth were d...
