“…Studies have observed that the incorporation of particles into the hybrid layer may lead to an increase in energy occurring during failure, resulting in fracture propagation into substrates (in dentin or resin) other than the bond interface [35]. Tranquilin et al [11] showed that the use of 2.5% TiF 4 as dentin pretreatment led to an increase in the frequency of cohesive failures in dentin when the convention three-step adhesive system was used, shown by means of the microtensile bond strength test. Similarly, Devabhaktuni and Manjunath [10] observed higher frequency of cohesive and mixed failures in resin when using the shear test.…”

“…Dündar et al [9] verified that pretreatment with an aqueous solution of 2.5% titanium tetrafluoride (TiF 4 ) interfered in the bond strength of adhesive cements to dentin. For etchand-rinse adhesive systems, Devabhaktuni and Manjunath [10] observed that the application of a 4% aqueous solution of TiF 4 before or after acid etching when using a 3-step adhesive system had no influence on the bond to dentin, whereas Tranquilin et al [11] verified that the use of pretreatment with 2.5% TiF 4 promoted higher bond strength values of a two-step adhesive system to dentin. In addition, a hybrid layer micromorphology with the formation of more numerous and larger diameter tags was obtained, showing the favorable effects of using this pretreatment.…”

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.

“…The titanium tetrafluoride (TiF 4 ) is another solution that has been studied. The TiF 4 is an intermediately strong acid (pH about 1.5), capable to promote adhesion between the titanium and the oxygen atom from phosphate groups, forming a vitreous layer, resistant to acid and alkaline solutions 18–25 . Considering that SARCs are composed by acidic components, including phosphoric acid groups, the application of titanium tetrafluoride molecules into the hybrid layer could be relevant for the bonding mechanism.…”

Objectives: To evaluate the influence of dentin pretreatments on the push-out bond strength (POBS) of self-adhesive resin cements (SARCs) to radicular dentin. Materials and Methods: Two experimental pretreatments (2.5% titanium tetrafluoride (TiF 4 ) and 26% polyacrylic acid (PA)) and two SARCs: Maxcem Elite (MAX) and Calibra Universal (CAL) were used. For each cement, a control group was applied as indicated by the manufacturer. Sixty bovine incisors were restored (n = 10) and subjected to POBS evaluation. Failure mode, adhesive interface and surface morphology were analyzed by a Scanning Electron Microscopy (SEM) and resin infiltration was performed by confocal laser scanning microscopy (CLSM). Data for POBS and CLSM were analyzed by three-way ANOVA and Bonferroni post-hoc (α = 0.05).Results: For MAX, both experimental pretreatments resulted in increased POBS in the cervical third, and for CAL, only the PA resulted in higher POBS in the cervical third. The most failures occurred between the dentin and the resin cement, except when TiF 4 was applied. For PA, analysis of surface morphology showed open dentinal tubules, while TiF 4 presented particle agglomerates. SEM and CLSM images confirmed presence of resin tags for both pretreatments. Conclusion:Pretreating radicular dentin with PA and TiF 4 solutions improves the bond strength of SARCs.

TiF4 improves microtensile bond strength to dentin when using an adhesive system regardless of primer/bond application timing and method

Abstract: Pretreatment with TiF(4) increased bond strength in a conventional two-step adhesive system to dentin, regardless of the primer/adhesive application method and the timing of dentin pretreatment.
