Neutralizing effect by resin-based materials containing silane-coated glass fillers

Abstract

The aim of this study was to evaluate the fluoride release, neutralizing ability and inhibitory effect on secondary caries of resin-based materials containing a silane-coated glass filler. Resin-based materials containing fluoro-boro-alumino-silicate glass coated by 3-methacryloxypropyltrimethoxysilane or 3-aminopropyltrimethoxysilane were used and resin material containing glass filler without coating was used as a control. The fluoride release and pH value after immersion were measured for 10 weeks. The inhibitory effect was also evaluated. During the initial period, the material with 3-aminopropyltrimethoxysilane gave the greater amount of fluoride release and produced a higher pH value compared with the other materials. However, the neutralizing ability of the material with 3-aminopropyltrimethoxysilane filler became weaker with ageing of the specimens. The mean depth of outer lesions was similar among the three materials. Within the limitations of this study, secondary caries around restorations could not be inhibited even for products showing high fluoride releasing and neutralizing ability.

Acid neutralizing, mechanical and physical properties of pit and fissure sealants containing melt-derived 45S5 bioactive glass

“…Efforts were made to develop a resin-based material that contained 3-aminopropyltrimethoxysilane-coated glass filler, which was shown to have an acid neutralizing effect. However, this effect was insufficient to produce a cariostatic function due to weak alkalinity [28]. Other studies have developed novel composites that contained nano-sized amorphous calcium phosphate (NACP) filler.…”

The Influence of Mixing Methods on the Compressive Strength and Fluoride Release of Conventional and Resin-Modified Glass Ionomer Cements

“…The silane-coupling agent, a bonding agent between filler particles and resin matrix polymer, has been widely used to improve the mechanical properties of the resin composite. Bisphenol-A-glycidyl methacrylate/triethylene-glycol-dimethacrylate (Bis-GMA/TEGDMA) resin containing silanized NaF particles released a small amount of fluoride for a long duration while the resin containing nonsilanized NaF particles released a large amount of fluoride [36, 37]. Some silanes are highly hydrophobic, and this would prevent the water from wetting the surface of the particles and preventing the release of fluoride ions [38, 39].…”

This so-called dry method is exemplarily described by Itota et al 18 and is commonly used for applying coupling agents to filler or adherends. 19 Within the scope of optimization measures, scanning parameters -based on a suitable initial parameter setup -were systematically changed by successive approach as well as the thickness of the cooper prefilter.…”
