BACKGROUND There is limited evidence on possible associations between social determinants and dental pain. This study investigated the relationship of neighborhood and individual social capital with dental pain in adolescents, adults and the elderly. METHODS A population-based multilevel study was conducted involving 624 subjects from 3 age groups: 15-19, 35-44 and 65-74 years. They were rand...

the efficacy of correctly applied fissure sealants has been revealed in the prevention of caries. saliva and moisture contamination of the etched enamel surface before sealant placement can decrease the bonding strength of the sealant to the enamel. the aim of this study was to test the new bonding agents containing nano-fillers in order to reduce the negative effect of saliva contamination on ...

Problem statement: All-ceramic materials, especially silica-based lithium disilicate and nonsilicate-based Zirconia, have become a topic of interest in the field of dentistry. It is still difficult to achieve a strong and durable resin-ceramic adhesion, especially resin-Zirconia bonding. Approach: The article reviews the current literature published in the past 5 years, focusing on the latest r...

Objective: The bonding adhesive holds the composite filling to the residual tooth, creating a chain cross-–link during the photo polymerization process. In this article we will be discussing the polymerization process under a thermodynamic viewpoint between amorphous structures of the dental market adhesives, the hybrid layer of the residual tooth and the white polymers filling. The thermodynam...

OBJECTIVE The purpose of this in vitro study was to explore the radiopacity of composite resins and bonding materials using film and phosphor plates. METHODS Nine composite dental resin specimens and human tooth slices were exposed together with an aluminium stepwedge using dental film and phosphor plates. Eight dentin bonding specimens were prepared and exposed in a similar manner. Their rad...

OBJECTIVE To evaluate the influence of bonding and debonding of orthodontic brackets on dental in-home bleaching, taking into account three different adhesive systems. METHODS Forty-four bovine incisors were divided into four groups according to the primer system used for orthodontic bracket bonding. Following the debonding of orthodontic brackets, the teeth were stored in staining solution f...

Objectives Many advantages have been attributed to dental zirconia ceramics in terms of mechanical and physical properties; however, the bonding ability of this material to dental structure and/or veneering ceramics has always been a matter of concern. On the other hand, hydroxyapatite (HA) shows excellent biocompatibility and good bonding ability to tooth structure, with mechanically unstable ...

Dental adhesives used to bond composite resins to tooth structure have evolved over the last several decades. The earliest bonding systems required an acid-etch technique and were only compatible with enamel, and the challenge has always been to predictably bond to enamel and dentin simultaneously. There can be confusion as to what bonding agents are being described, because there are a number ...
