“…Moreover, an excessive solvent concentration in an adhesive can inhibit selfpolymerization 30) . One of the methods currently used to evaporate solvents from adhesives has been air-drying prior to light irradiation 6,31,32) . However, it is diffi cult to completely evaporate the solvents.…”

The purpose was to evaluate the effect of air-drying dentin surfaces on the microtensile bond strength (μTBS) of a solvent-free onestep adhesive (Bond 1 SF). Twelve human molars were ground with 600-grit SiC paper. Before applying bonding agent, the dentin surface was rinsed with distilled water and blot-dried with tissue paper, followed by air-drying for 0, 3, 30, and 60 s using with a dental air syringe. After applying and curing Bond 1 SF, resin composite was incrementally built up. Specimens were then stored in distilled water for 24 h and then μTBSs were measured at a cross-head speed of 1 mm/min. Higher μTBS were observed when the dentin surface was air-dried for 3 s (33.2±6.8MPa)>0 s (26.7±4.5MPa)>30 s (22.6±5.5MPa)=60 s (20.4±5.0MPa). The results suggested that prolonged air-drying of the dentin surface removed water and decreased the bond strengths of Bond 1 SF.

“…Although the manufacturer's guide only recommends evaporating the volatile ingredients for 20 s with a mild oil-free air stream after conditioning the tooth surface, a definite drying time has not been specified. The duration of air-drying has been reported as one of the factors affecting the bond strength [39][40][41]. This study clarified the necessity of extended airdrying for solvent evaporation.…”

“…Relative humidity at molar sites is close to 100 % [9][10][11]. Resin bonding in a high humidity environment has been reported to reduce bond strength [11,12,39]. Therefore, it is recommended to restore posterior teeth under humidity-controlled conditions.…”

“…During the bonding procedure, these effects immediately promote less residual solvent and improve the wettability of the tooth surface 11,14,15 , positively affecting the hybrid layer formation. Therefore, at least theoretically, the enhanced bonding effectiveness of an adhesive system could be the result of a temperature increase altering the physicochemical properties of the solutions involved 16 .…”

“…Increased adhesive temperature promotes superior solvent evaporation and reduces the adhesive viscosity, hypothetically ensuring a stable and lasting bond [6][7][8][9][10][11][12] . Enhanced solvent evaporation limits the residual solvent 13 , enhances wettability 11,14,15 -which influence the hybrid layer formation positively 16 -and yields a highly reticulated polymer, with reduced water sorption and lower hybrid layer solubility 17 .…”

ResumoIntrodução: O aumento da temperatura do adesivo tem sido pesquisado como forma de melhorar a evaporação do solvente, reduzir a viscosidade e melhorar a permeação dos monômeros na dentina. Objetivo: Investigar a influência de diferentes métodos de aquecimento na resistência de união à dentina sob um ensaio de microtração de um adesivo de condicionamento ácido total. Material e método: Vinte e quatro terceiros molares hígidos foram seccionados transversalmente a fim de expor a superfície plana da dentina. As amostras foram condicionadas ácido fosfórico a 37% e dividido em três grupos (n=8). São eles: 1) Controle -onde o adesivo (Adper Single Bond 2, 3M ESPE) foi aplicado em temperatura normal (25°C); 2) Dispositivo de aquecimento -O adesivo foi aquecido em um dispositivo específico até alcançar a temperatura de 37°C e só então aplicado à dentina; 3) Ar quente -Usou-se jato de ar aquecido a 50°C por 10 segundos a uma distância de 10cm para facilitar a evaporação do solvente. Os espécimes foram restaurados com resina composta (Filtek Z250 A2, 3M ESPE) e preparados para o ensaio de microtração, após 24h de armazenamento em água destilada. Os dados obtidos foram submetidos para análise de variância (ANOVA) e teste de Tukey (p<0,05). Resultado: Não houve diferença significativa entre os grupos (p>0,05). As médias da resistência de união para o grupo controle, dispositivo de aquecimento e ar quente foram, respectivamente, 48,5 (± 5,2), 40,35 (± 4,9), e 47,2 (± 5,3). Conclusão: Os diferentes métodos de aquecimento não influenciaram significativamente na resistência de união imediata à dentina de um Sistema adesivo de condicionamento ácido total.Descritores: Adesivos dentinários; dentina; temperarutra; adesão. AbstractIntroduction: Increased adhesive temperature has been reported to promote solvent evaporation, reduce viscosity, and improve monomeric permeation into dentin. Objective: The aim of this study was to determine the influence of different heating methods on the microtensile bond strength of an etch-and-rinse adhesive to dentin. Material and method: Twenty-four caries-free extracted human third molars were transversally sectioned to expose a flat dentinal surface. The samples were etched with 37% phosphoric acid gel and divided into three groups (n = 8): 1) Control -the adhesive system (Adper Single Bond 2; 3M ESPE) was applied at room temperature; 2) Warming device -the adhesive was warmed to 37°C in a custom device before application; and 3) Warm air -the adhesive was warmed to 50°C with an air jet after application on dentin. The specimens were restored with a composite resin (Filtek Z250 A2, 3M ESPE) and prepared for microtensile bond strength testing, after 24 h in water storage. The data were subjected to one-way ANOVA and Tukey's test (p < 0.05). Result: There was no significant difference among the groups (p > 0.05). The mean bond strength values in the control, the warming device, and the warm air groups were 48.5 (± 5.2), 40.35 (± 4.9), and 47.2 (± 5.3) MPa, respectively (p = 0.05). Conclusion: T...
