Aim: This review investigated the effect of applying an adhesive after surface treatment glass-ceramics on bonding, mechanical or clinical behavior. Methods: Studies comparing adhesive, behavior glass-ceramics, with without application treatment, were included. Searches performed in PubMed, Scopus, and Web Sciences databases (January 2022), resulting 15 included studies. Results: Regarding eval...

This work reports the high-velocity impact response of multiscale anisogrid composite (AGC) panels. The aim of the present study is to evaluate the influence of surface-modified multi-walled carbon nanotubes (S-MWCNTs) at different S-MWCNTs contents (0-0.5 wt.% at an interval of 0.1 wt.%) on the high-velocity impact responses of E-glass/epoxy AGC. Surface modification of MWCNTs is confirmed by ...

A novel welding technique of diffusion bonding for Zr-Cu metallic glass with pre-oxidized surfaces is proposed in this study, which systematically investigated by molecular dynamics (MD) simulation. Compared the conventional technique, process can be well implemented below crystallization temperature glass. The obtained structure possesses glass–glass interfaces (GGIs) similar those nano-glasse...

OBJECTIVE The objective of this study is to test the antimicrobial effect of zinc oxide when incorporated into an orthodontic bonding material and to check the effect of addition of zinc oxide on the shear bond strength of the bonding material. MATERIALS AND METHODS Zinc oxide was added to a resin modified light cure glass ionomer cement (GIC) (Fuji Ortho LC GC America, Alsip, Ill) to make mo...

The key research and development steps for bioactive glass (45S5 Bioglass) are documented from the date of discovery in 1969 through FDA approvals of the first dental, ENT, maxillo-facial and orthopedic clinical products. Understanding the mechanisms and quantifying the rapid surface reactions to form a bone-bonding hydroxyl-carbonate apatite (HCA) layer on the bioactive glass in contact with l...

Objectives. To examine the effect of immediate dentin sealing (IDS), with dentin bonding agents (DBAs) applied to freshly cut dentin, on the shear bond strength of etched pressed ceramic luted to dentin with RelyX Unicem (RXU) cement. Method. Eighty extracted noncarious third molars were ground flat to expose the occlusal dentin surfaces. The teeth were randomly allocated to five groups (A to E...

Abstract This paper deals with the study and development of polymer-based adhesive high filling ratio secondary raw materials waste materials. The goal this is to develop mortar highest rate as possible while preserving very physical-mechanical properties, including flexural compressive strength, pull-off bond strength abrasion resistance. High-temperature fly ash, slag packaging glass are used...

General structure and properties Glass-ionomer cements were developed by Wilson and McLean at the Laboratory of the Government Chemist in England in 196527. They were a logical addition to the family of water-based dental cements, comprising silicate cement, zinc phosphate cement and zinc polycarboxylate cement. Since their commercial introduction, they are now available in essentially two type...

Glass fibres: absence of pulmonary hazard in production workers. Seventy fibreglass workers with a mean of 19-85 years in the industry are compared with a control group having no exposure to glass fibre but otherwise matched for age, sex, height, and weight, and residing in the same geographical area. Comparison was made by radiography, the administration of the modified Medical Research Counci...
