“…It is more likely that the heated NaOCl has a direct effect on the interface between mineral and collagen. This is consistent with the effect of saline at 80°C, where there may be a mild effect on the collagen-mineral bonding interface through increase in the mean length of vibrating chain segments (29). Collagen shrinks on heating at 70°C in saline solution but falls apart at temperatures higher than 80°C (16).…”

“…In the presence of NaOCl, the effect is likely enhanced by deeper penetration of NaOCl into dentin and thus probable damage to protein interface with the mineral structure (12). This may cause anelastic behaviour in the mineral matrix (29), coupled with greater damping effect. The potential clinical relevance of these two phenomenon is that the increased viscosity would cause greater strain, whilst the loss of elasticity or anelastic behaviour may delay recovery.…”

“…Os sistemas auto condicionantes não utilizam o condicionamento ácido da dentina, resultando assim, na desmineralização parcial do tecido e preservando maior quantidade de hidroxiapatita, responsável pela proteção das fibrilas colágenas (VAN MEERBEEK et al, 2003;DE MUNCK, VAN LANDUYT et al, 2005;VAN LANDUYT et al, 2006, BULUCU ET AL., 2009PEUMANS et al, 2010). Clinicamente, a degradação do colágeno interfere negativamente na formação da camada híbrida (TURCO et al, 2016), além do que, a matriz colágena degenerada tem sua elasticidade diminuída (AMADORI et al, 2013), aumentando a incidência de fraturas (HATIBOVIĆ-KOFMAN et al, 2008). Trabalhos prévios relataram que a desmineralização completa do substrato dentinário alterado pela radioterapia resulta em redução acentuada das propriedades mecânicas além de danos irreparáveis às fibras colágenas (DAVIS, 1975;PIOCH et al, 1992;KIELBASSA et al, 1997;GERNHARDT et al, 2001;FRANZEL et al, 2006;SOARES et al, 2011;GONÇALVES et al, 2014).…”

“…Clinicamente, a degradação do colágeno dentinário interfere negativamente na formação da camada híbrida durante a utilização de sistemas adesivos sobre a dentina (Turco et al, 2016). Além disso, o tecido dentinário constituído de fibras colágenas degeneradas, tem a sua elasticidade diminuída (Amadori et al, 2013), com consequente aumento da incidência de fraturas (Hatibović-Kofman et al, 2008).…”
