“…A pobre atuação deste sistema adesivo em dentina seca foi atribuída a uma proporção inadequada de água e etanol neste produto, podendo não ser suficiente para permitir a reexpansão das fibras colágenas desidratadas 20 . Embora desfavoráveis para o Single Bond, os resultados do presente estudo corroboram outros que afirmam que primers à base de água apresentam igual eficácia de adesão em dentina seca ou úmida, devido a sua capacidade de reumidificar e reexpandir as fibrilas colágenas, permitindo a adequada infiltração do adesivo no interior da dentina desmineralizada 21 .…”

Objetivo: Avaliar a infiltração marginal na interface formada com três sistemas adesivos convencionais (XP Bond ® , Single Bond 2 ® e Scotchbond Multi-Uso ® ), segundo o grau de umidade da dentina decídua. Métodos: Trinta preparos classe V foram alocados em seis grupos, segundo o tipo de adesivo e modo de secagem da dentina (seca ou úmida). Após restauração e envelhecimento artificial por 30 dias, os corpos de prova foram imersos em nitrato de prata a 50% por 24h. O grau de infiltração marginal foi medido através de escores relacionados à penetração do traçador pelas margens da restauração. Testes não-paramétricos de Kruskal-Wallis e Mann-Whitney (α=5%) foram utilizados. Resultados: Menores escores para infiltração marginal foram encontrados para o XP Bond ® comparado aos outros adesivos. Segundo o tipo de dentina, não observou-se diferença entre dentina úmida e seca nos grupos XP Bond ® e Single Bond 2 ® , porém neste, 55% dos espécimes apresentaram algum grau de infiltração. Para o Scotchbond Multi-Uso ® , melhores resultados foram encontrados para dentina seca. Segundo grupos com o mesmo grau de umidade na dentina, não houve diferença entre XP Bond ® e Single Bond 2 ® em dentina úmida. Em dentina seca, escores mais baixos de infiltração foram encontrados para o XP Bond ® . Não foram detectadas diferenças entre XP Bond ® e Scotchbond Multi-Uso ® tanto em dentina úmida quanto em dentina seca. Para a comparação Single Bond 2 ® vs. Scotchbond Multi-Uso ® não foram encontradas diferenças em dentina úmida, porém, em dentina seca, menor grau de infiltração foi obtida para o Scotchbond MultiUso ® . Conclusão: Quanto à infiltração marginal, o XP Bond® apresentou eficiência na adesão em dentina decídua úmida ou seca. O Scotchbond Multi-Uso ® pode apresentar indicação em dentina decídua seca, enquanto que o Single Bond 2 ® não foi eficiente para ambos os tipos de dentina decídua.Dente Decíduo; Infiltração Dentária; Adesivos Dentinários. , according to the moisture of primary tooth dentin. Method: Thirty class V cavities were assigned to 6 groups according to the adhesive system and dentin condition (dry or moist). After restoration and artificial ageing for 30 days, the specimens were immersed in 50% silver nitrate for 24 h. The intensity of marginal infiltration was determined by scores related to the tracer penetration through the dentin/restoration margins. Non-parametric Kruskal-Wallis and Mann-Whitney tests were used for statistical analysis (α=5%). Results: Lower marginal infiltration scores were found for XP Bond ® compared with the other adhesive systems. Regarding dentin condition, there was no difference between dry and moist dentin for XP Bond ® and Single Bond 2 ® , but 55% of the specimens treated with latter exhibited some degree of infiltration. For Scotchbond Multi-Purpose ® , the best results were obtained with dry dentin. Comparing the groups with the same dentin condition (dry or most), there was no difference between XP Bond ® and Single Bond 2 ® for moist dentin. Lower infiltration scores were obtai...

“…[4][5][6] In order to enhance the optimal formation of a hybrid layer, demineralized dentin has to be kept moist and collagen network maintained in a fully expanded state after acid etching or if dried, need to be re-wetting. 7) The presence of water play a crucial role in preventing the demineralized surface collagen from collapsing following dehydration. 8) When airdried demineralized dentin is re-wet with water, the collagen matrix re-expands and completely recovers the original dimensions to the levels of the original hydrated state 7) because spaces between fibrils is refilled with water and hydrogen bond between collagen fiber that restrain the adhesive resin infiltration is broken by water.…”

Proteoglycan is highly hydrophilic and negatively charged which enable them attract the water. The objective of study was to investigate the effects of Proteoglycan on microtensile bond strength of dentin adhesives and on architecture of dentin collagen matrix of acid etched dentin by removing the chondroitin sulphate attached on Proteoglycan. A flat dentin surface in mid-coronal portion of tooth was prepared. After acid etching, half of the specimens were immersed in 0.1 U/mL chondroitinase ABC (C-ABC) for 48 h at 37℃, while the other half were stored in distilled water. Specimens were bonded with the dentin adhesive using three different bonding techniques (wet, dry and re-wet) followed by microtensile bond strength test. SEM examination was done with debonded specimen, resin-dentin interface and acid-etched dentin surface with/without C-ABC treatment.For the subgroups using wet-bonding or dry-bonding technique, microtensile bond strength showed no significant difference after C-ABC treatment (p > 0.05). Nevertheless, the subgroup using rewetting technique after air dry in the Single Bond 2 group demonstrated a significant decrease of microtensile bond strength after C-ABC treatment. Collagen architecture is loosely packed and some fibrils are aggregated together and relatively collapsed compared with normal acid-etched wet dentin after C-ABC treatment. Further studies are necessary for the contribution to the collagen architecture of noncollagenous protein under the various clinical situations and several dentin conditioners and are also needed about long-term effect on bond strength of dentin adhesive.

This study investigated that the effect of rewetting agent on dentinal microtensile bond strength (μ TBS). Human molars were sectioned to expose the superficial dentin surfaces.Samples were divided into two groups according to type of adhesives-Single Bond (S) and One-Step (O)〕 , and again subdivided into five groups by different dentin surface treatment-dry for 15s (D), blot dry (BD) or dry for 15s, and rewet with different rewetting agents 〔distilled water (DW), Gluma Desensitizer (GD) and AquaPrep (AP)〕 for 30s. After application of adhesive, composite resin was built up on the bonding surface. Each tooth was sectioned to obtain stick with 1 mm 2 cross sectional area and the μ TBS was determined by EZ test.In the S group, the mean μ TBS of GD, AP and BD group was significantly higher than that of DW and D group (p < 0.05). In the O group, the mean μ TBS of AP, GD, BD and DW group was significantly higher than that of D group (p < 0.05).The data suggested that Gluma Desensitizer and Aqua-Prep could be successfully used as rewetting agents, and Distilled water could be acceptable in aceton based adhesive system only.
