Assessment of defects at tooth/self-adhering flowable composite interface using swept-source optical coherence tomography (SS-OCT) was written by Park, Kyung-Jin;Schneider, Hartmut;Haak, Rainer. And the article was included in Dental Materials in 2015.Reference of 109-17-1 This article mentions the following:
Assessment of adhesive defects of a self-etch adhesive and a self-adhering flowable composite at the tooth/composite interface before and after water storage by optical coherence tomog. (OCT).16 extracted human molars (n = 8 each) with box-shaped, class-V cavities were restored either with an exptl. self-adhering flowable composite (EF, DMG) or with the filling system Adper Prompt L-Pop/Filtek Supreme XT Flowable composite (PLP, 3M ESPE). Restorations of both groups were non-invasively imaged using swept-source OCT before and after storage in water. The OCT signal for adhesive defects at the tooth/composite interface was quantified.At enamel, significantly fewer adhesive defects were detected at EF restorations than at PLP restorations, before water storage (4%/48%, p < 0.001) and thereafter (8%/49%, p < 0.001); in contrast, at dentin more interfacial defects were observed with EF (before water storage: 75%/11%; p < 0.001, after water storage: 77%/52%; pi = 0.001). In the case of slight initial adhesive defects, water storage caused a statistically verifiable increase in adhesive defects at the enamel interface with EF (before/after storage: 4%/8%; p = 0.023) and at dentin with PLP (before/after storage: 11%/52%; p = 0.008).Given the high proportion of adhesive defects with the exptl. self-adhering flowable composite, its use as the definitive restorative material in class-V cavities must be critically scrutinized and clin. indications must be investigated further with in vitro and in vivo trials. In the experiment, the researchers used many compounds, for example, ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1Reference of 109-17-1).
((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Reference of 109-17-1
