Aim. To investigate the effect of C factor on marginal adaptation of low-shrinking composite (Silorane).The null hypothesis was that the marginal adaptation of "Silorane" is not affected by the cavity configuration. Materials and Methods. A Silorane based and a methacrylate based composites, with their corresponding self-etch adhesive systems "Filtek Silorane/Silorane Adhesive Bond System and F...

Whilst hydrogels and hollow particles both continue to attract much attention in the literature there are few examples of hydrogel composites containing hollow particles. Here, we study composite polyacrylamide (PAAm) hydrogels containing micrometer-sized pH-responsive shell-crosslinked hollow particles (abbreviated as HPXL) based on poly(methylmethacrylate-co-methacrylic acid) functionalised w...

OBJECTIVE The objective was to investigate the way that various surface treatments could influence the bond strength of the repair of methacrylate (MC) and silorane (SIL) composites. MATERIALS AND METHODS A total of 160 MC and SIL cylindrical specimens were polymerized and aged in artificial saliva solution for 7 days. Depending on the following surface treatment (diamond bur or air abrasion)...

Purpose: A radiopaque self-polymerizing adhesive resin was prepared by incorporating bismuth subcarbonate-poly(methyl methacrylate) prepolymerized composite (BS-PMMA) into an acrylic resin. The purpose of this study to evaluate the radiopacity resins.Methods: As a component, containing 50% subcarbonate used, and other metal compounds were adopted as controls. They added finely pulverized PMMA. ...

In this study, medical hydrogels (TGs) were fabricated based on thiolate-modified chitosan (TCS) and methacrylate gelatin (GelMA) using the Thiol-Michael addition reaction. The formed via Michael reaction between TCS GelMA determined to have an equilibrium swelling rate of more than 1100% while simultaneously providing a moist environment for wound, limiting crust formation. porosity prepared h...
