OBJECTIVE The purpose of this study was to assess by means of scanning electron microscopy (SEM) the remaining adhesive interface after debonding orthodontic attachments bonded to bovine teeth with the use of hydrophilic and hydrophobic primers under different dental substrate moisture conditions. MATERIAL AND METHODS Twenty mandibular incisors were divided into four groups (n = 5). In Group ...

Reliable cementation of fixed prosthetic restorations represents one of the most sensitive and crucial tasks during the prosthetic dental treatment with desirable long term clinical success. Because of its particular structure, zirconia restorations require a special conditioning before cementation in order to achieve a strong bond to dental structure. The lack of information about adhesive cem...

12 INTERNATIONAL DENTISTRY SA VOL. 8, NO. 4 A dvances in the field of adhesive restorative biomaterials have resulted in adhesive restorations that provide increased retention, marginal adaptation and seal, and reduced microleakage. This evolution in adhesive dental technology has dramatically changed the way dentistry is practised in the modern dental office. Modern adhesive restorative materi...

INTRODUCTION Despite its origins in the mid-1950s with a bone adhesive called Ostamer [1], the development of bone adhesives is still in its early stages and is not a mature field. There lacks a consensus on aspects of adhesive performance and bond strength measurement. As a result, there are not standard tests for quantifying and evaluating the adhesive strength at the interface between the bo...

The incorporation of polymerizable cationic monomers has been attempted to generate dental resinous materials with antibacterial activity. This study tested the hypothesis that a dental adhesive containing a cationic monomer, methacryloxylethyl cetyl dimethyl ammonium chloride (DMAE-CB), would influence biofilm formation and gtf gene expression of Streptococcus mutans. The effect of the photo-p...

introduction: when aesthetics is compromised, dental ceramics are excellent materials for dental restorations; owing to their optical properties and biocompatibility, zirconia ceramics are particularly interesting. self-adhesive resin cements are the most suitable for bonding to zirconia ceramics, but traditional adhesive chemistry is ineffective and surface treatments are required to improve t...

This study reports a synthetic polymer functionalized with catechol groups as dental adhesives. We hypothesize that a catechol-functionalized polymer functions as a dental adhesive for wet dentin surfaces, potentially eliminating the complications associated with saliva contamination. We prepared a random copolymer containing catechol and methoxyethyl groups in the side chains. The mechanical a...

Adhesion is the procedure of forming an adhesive joint. The initial substrate is termed adherend and the material producing the interface is termed the adhesive [1]. The functions of dental adhesives is to promote conservation of tooth structure and enable minimally invasive dentistry, reinforcement of weakened dentin or enamel, reduce marginal staining, reduce microleakag and may also reduce p...
