“…This is particularly applicable to adhesives that contain an increasing amount of hydrophilic resin monomers that absorb water such as all-in-one adhesives. Other studies showed that both hydrophilic resins (Ichim et al 2007a , b ) and collagen fi brils within the hybrid layer (Hashimoto et al 2000(Hashimoto et al , 2001(Hashimoto et al , 2003Armstrong et al 2004 ;Ichim et al 2007a ) degrade upon long-term water storage.…”

Many reports have indicated that resin bond strengths to noncarious sclerotic cervical dentin are lower than bonds made to normal dentin. This is thought to be due to tubule occlusion by acid-resistant mineral salts, preventing resin tag formation following acid etching. The purpose of this review was to critically examine what is known about the structure of this type of dentin. Recent transmission electron microscopy revealed that in addition to occlusion of the tubules by mineral crystals, many parts of wedge-shaped cervical lesions contain a hypermineralized surface that resists the etching action of both self-etching primers and phosphoric acid. This layer prevents hybridization of the underlying sclerotic dentin. In addition, bacteria are often detected on top of the hypermineralized layer. Sometimes the bacteria were embedded in a partially mineralized matrix. Acidic conditioners and resins penetrate variable distances into these multilayered structures. Examination of both sides of the failed bonds revealed a wide variation in fracture patterns that involved all of these structures. Microtensile bond strengths to the occlusal, gingival, and deepest portions of these wedge-shaped lesions are signifi cantly lower than similar areas artifi cially prepared in normal teeth. When resin bonds to sclerotic dentin are extended to include peripheral sound dentin, their bond strengths are probably high enough to permit retention of class V restorations by adhesion, without additional retention.

“…Thus, the adhesive restoration favors a biomechanical behavior similar to the tooth without WS lesion [43,44], Paiva, 2003. On the other hand, the oblique loading generated stress concentration in the cervical restoration, resulting in possible failure of the restoration due to the gaps in the adhesive interface [13,45,46] Paiva (2203). This fact suggests that only the WS lesion restoration is not enough to significantly reduce the stress concentration and strain values in the cervical region.…”

“…The geometric complexity and material heterogeneities demand the numerical approximation of the stress and load analysis (Amarante et al, 2008;Chan et al, 2007;Freitas et al, 2010aFreitas et al, , 2010bIchim et al, 2007;Li et al, 2006;Papadopoulos et al, 2010). A two dimensional finite element model was adopted in order to investigate the stress fields generated in the tooth-adhesive-veneer system when subjected to thermal and mechanical loadings that develop during the natural occlusal, mastication or deglutition procedures.…”
