“…Em 2012, Assad-Loss et al 4 verificaram a influência da saliva na ação da resistência adesiva dos adesivos em esmalte dental. Foram avaliados 3 adesivos diferentes, sendo eles o Transbond XT, Transbond MIP e o Single Bond e utilizaram dentes bovinos com e sem contaminação de saliva para o teste de resistência adesiva, chegando a conclusão que a queda da resistência adesiva é significativa.…”

ResumoOs novos materiais restauradores têm sido desenvolvidos para atender as exigências dos clínicos e obter um nível de excelência tanto em termos funcionais quanto em estética. Com isso, uma grande variedade de produtos odontológicos é lançada no mercado a cada ano, dentre esses produtos temos os sistemas adesivos odontológicos e junto a eles surgem diferentes técnicas de utilização. Portanto é estritamente importante o conhecimento do profissional durante a seleção e aplicação desses sistemas adesivos. A elaboração dessa revisão foi impulsionada devido a grande quantidade de sistemas disponíveis hoje e buscou compreender a fundo a aplicação desses sistemas de acordo com as pesquisas dos últimos 5 anos. Essas pesquisas nos trouxeram dados altamente significativos, tais como: que o aumento do tempo de aplicação dos sistemas autocondicionantes leva a uma melhora na resistência adesiva; os novos conceitos de hibridização a partir da desproteinização da dentina e fixação da clorexidina como inibidor efetivo de metaloproteinases.

AbstractThe new restorative materials have been developed to meet the requirements of clinicians and achieve a level of excellence in both functional and aesthetic terms. With this, a great variety of dental products is launched on the market every year, among these products we have the dental adhesive systems and with them come different techniques of use. Therefore, the professional's knowledge during the selection and application of these adhesive systems is strictly important. The elaboration of this review was boosted due to the large number of systems available today and sought to thoroughly understand the application of these systems according to the surveys of the last 5 years. These researches have brought us highly significant data, such as: that the increase of the time of application of the self-conditioning systems leads to an improvement in the adhesive resistance; the new concepts of hybridization from dentin deproteinization and fixation of chlorhexidine as an effective inhibitor of metalloproteinases.

Objective: It is claimed that a hydrophilic primer, called the moisture insensitive primer (MIP), can be used with both dry and wet enamel surfaces. This study sought to assess the shear bond strength (SBS) of APC Plus adhesive coated appliance system to enamel using MIP in wet and dry conditions. Materials and methods:This in vitro experimental study evaluated 24 extracted maxillary premolars with intact buccal enamel. The teeth were randomly divided into two groups (n=12), and APC Plus premolar brackets were bonded to their buccal surface using moisture insensitive primer (MIP) under wet and dry enamel conditions. The SBS values were measured by a universal testing machine. The adhesive remnant index (ARI) score was also determined under a stereomicroscope. Data were analyzed using t-test and Mann-Whitney test at P<0.05 level of significance. Results:The SBS in wet condition was significantly lower than that in dry condition (mean value of 18.37MPa versus 25.5MPa, P<0.001). The two groups had no significant difference regarding the ARI scores (P>0.05). However, in both groups, less adhesive was left on the tooth surface. This suggests that bond failure occurred at the adhesive-enamel interface.Conclusions: APC Plus adhesive coated appliance system in combination with hydrophilic MIP can be effective in clinical conditions with high risk of moisture contamination.

Background:There is necessary of dry operating field for bonding of orthodontic brackets. The presence of moisture can alter the bond strength. Hence, the aim of the present study was to evaluate the shear bond strength of orthodontic brackets with different adhesives.Materials and Methods:In this in vitro study, a total of 100 orthodontically extracted premolars with sound crown structure were divided into 4 equal groups of different primers. Bonding on the buccal surface of all teeth was done after acid etching with upper premolar brackets using different primers followed by light curing. Shear bond strength was evaluated with or without salivary contamination with both adhesives. A shear force for deboning the bracket was done with universal testing machine. The debonded specimens were examined at ×10 magnification to check site of bond failure and remaining adhesive on tooth using adhesive remnant index (ARI). The obtained data were statistically evaluated using SPSS 20 for Windows (SPSS Inc., Chicago, IL, USA) using ANOVA, Kolmogorov–Smirnov, and Levene's test at the statistical significance of P < 0.05.Results:Transbond Plus showed higher shear bond strength of 8.92 MPa under dry and 5.65 MPa with saliva contamination over Transbond XT of 7.24 MPa under dry and 2.43 MPa with saliva contamination, respectively. Higher ARI score was found without contamination in both adhesives.Conclusion:Transbond Plus hydrophilic resin had good shear bond strength under both dry and contamination condition compared to hydrophobic Transbond XT resin material.
