“…28 TEGDMA is a low molecular weight monomer, which shows high mobility and decomposes more quickly than larger molecules, such as Bis-GMA. 29 In our study, all composites, with the exception of Tetric N-Ceram Bulk Fill, contain TEGDMA in the organic matrix structure. Filtek Z250 also has a small amount of TEGDMA in the structure.…”

“…This then resulted in weak biofilm attachment that eventually caused the biofilm to detach easily from ES-DP. Another possible factor influencing bacterial adherence to resin composite surfaces was the amount of unpolymerized monomers in cured composites [41][42][43][44] . However, results from ATR-FTIR analysis in this study indicated that slight amounts of residual monomers were detected on the surface of both ES and GR composites.…”

Effect of Surface Characteristics on Adherence of S. mutans Biofilms to Indirect Resin Composites

The purpose of this study was to evaluate the adherence of biofilms to the surfaces of two indirect resin composites, Estenia C&B and Gradia. Slabs were prepared from the materials, and then either ground with 800-grit silicon carbide paper or polished with diamond pastes up to 1 μm. Artificial biofilms of Streptococcus mutans were grown on the composite slabs in an artificial mouth system for 20 hours. Thereafter, the amounts of retained biofilm on the surfaces were measured after sonication. Surface characteristics of the resins -such as surface roughness, amount of residual monomers, and distribution of filler particles -were examined. Two-way ANOVA revealed that the amount of retained biofilm varied (p<0.05) according to the composition and surface roughness of the material. In particular, biofilm adherence was lowest on Estenia C&B slabs when polished with diamond pastes up to 1 μm. It was thus concluded that the surface roughness and composition of a resin composite influenced biofilm adherence.

“…One-step self-etch adhesives act as permeable membranes even after polymerization and permit water movement across their thickness, which could accelerate elution of uncured monomers [32][33][34][35] . The lowered DC from monomer to polymer cause the low chemical stability and high solubility of adhesives [36][37] . Therefore, the lowered DC near the adhesive-composite join might compromise long-term stability between onestep self-etch adhesive and composite.…”

Polymerization behavior within adhesive layer of one- and two-step self-etch adhesives: A micro-Raman spectroscopic study

et al. 2013

This study investigated the polymerization behavior within the adhesive layer of one-and two-step self-etch adhesives at the dentincomposite interface. Dentin surfaces were applied with Clearfil S 3 Bond (TS), Clearfil S 3 Bond Plus (TSP) and Clearfil SE Bond (SE), and then placed with a light-curing resin composite. After water storage for 24 h, the bonded teeth were sectioned and polished perpendicular to the adhesive interface, and the degree of conversion (DC) of the adhesive layer between the dentin and composite were determined using micro-Raman analysis. For all the adhesives, the DCs of the adhesive layers significantly decreased near the adhesive-composite join (p<0.05). For the maximum DC value (P max ) and the DC value at the adhesive-composite join (P itf ), TS was significantly lower than TSP and SE (p<0.05). The polymerization of oxygen-inhibited layer at the top of the adhesive could not reach maximum DC even after polymerization of the overlying resin composite.
