Bonding of Adhesive Luting Agents to Caries-affected Dentin Induced by a Microcosm Biofilm Model

Abstract

Impairment of the mechanical properties of dentin promoted by carious lesions reduced the bond strength of adhesive luting agents.

Long-term effect of Er:YAG laser on adhesion to caries-affected dentin

“…However, bonding to SD remained stable after storage for 1 year under the same experimental conditions. These findings corroborate with other studies that evaluated the BS of natural or artificially prepared CAD [28,29]. The higher water volume in CAD [30] reduced calcium, phosphate, and magnesium levels [31] due to successive demineralization cycles, hindering the development of chemical bonds [30] to this tissue.…”

Selective carious tissue removal and glass ionomer liner reduction of pulp stress in bulk fill resin composite restorations

“…10 Partial removal of carious tissue is a conservative approach that preserves the underlying remineralized dentin. 11,12 Nonselective removal of hard carious dentin may not be necessary to ensure the longevity of resin composite restorations. 13 Adhesive procedures mediated by hybridization of demineralized dentin can reinforce the remaining tooth substrates, recovering the biomechanics principal.…”

“…13 Adhesive procedures mediated by hybridization of demineralized dentin can reinforce the remaining tooth substrates, recovering the biomechanics principal. 12 The preservation of the demineralized dentin layer on the pulp floor followed by the application of a protective liner using a resin-modified glass ionomer cement layer can contribute to biological and mechanical rehabilitation. 14 The stabilization of the pulp floor dentin and the induction of the formation of tertiary dentin can be followed by a temporary cavity 15 or definitive adhesive cavity sealing.…”

Avaliação do tratamento de superfície com laser de Er:YAG de pulso super curto sobre a adesão em dentina hígida e afetada por cárie: estudo longitudinal

“…Assim, por ser considerado um substrato de estudo com alta relevância clínica, estudos de adesão, que utilizam adesivo dentinário e resina composta como material restaurador, em dentina afetada, já vêm sendo realizados e demonstraram menor resistência de união quando comparados à adesão em dentina hígida (Arrais et al, 2004;Pereira et al, 2006;Wang et al, 2006;Ergucu et al, 2009;Komori et al, 2009;Mobarak et al, 2010a;Mobarak et al, 2010b;Scholtanus et al, 2010; Mobarak e El-Badrawy 2011; Alves et al, 2013;Peixoto et al, 2015).…”

“…Nesta circunstância, o correto vedamento da restauração na cavidade é de fundamental importância, pois possibilitará a interrupção do desafio desmineralizante, com consequente remineralização da dentina afetada, prevenindo remoção excessiva de tecidos duros do dente quando da reabertura das cavidades e geração de calor com maior tempo clínico. Contudo, a literatura mostra que adesão à dentina afetada por cárie é reduzida (Arrais et al, 2004;Pereira et al, 2006;Wang et al, 2006;Ergucu et al, 2009;Komori et al, 2009;Mobarak et al, 2010a;Mobarak et al, 2010b;Scholtanus et al, 2010; Mobarak e El-Badrawy 2011; Alves et al, 2013;Lenzi et al, 2015;Peixoto et al, 2015). Assim, torna-se fundamental que novas estratégias sejam propostas para modificar este cenário.…”
