HERNANDEZ BARRAGAN, Diana Carolina; CRUZ GONZALEZ, Alberto Carlos  and  CALVO RAMIREZ, Juan Norberto. Influence of silane and universal adhesives on adhesion during the repair of a ceromer. Rev. Odont. Mex [online]. 2018, vol.22, n.3, pp.160-164. ISSN 1870-199X.


There is no definitive protocol for ceromer repairs. Universal adhesives due to their composition and indications may be an alternative for polymeric restorations repair. But the association of silanes with universal adhesives requires more research.


To evaluate and compare the bond strength of two universal adhesives in ceromer - resin interface, associated or not with a silane agent.

Material and methods:

Six ceromer blocks were made and treated according to the following variables: (A) No treatment, (B) Silane agent, (C) Universal Adhesive 1 + Silane, (D) Universal Adhesive 1, (E) Adhesive Universal 2 + Silane, (F) Universal Adhesive 2 (n = 10). Composite resin was attached to these surfaces and a microtension test was performed. The type of failure was evaluated with a stereomicroscope.


The bond strength values of the groups were statistically different (p <0.05), except between both universal adhesives were evaluated. Group (B) presented the highest values of adhesive resistance. Groups (C and E) had lower adhesive strength values compared to groups (D and F). The most prevalent type of failure was the adhesive.


The associated use of functional silane to universal adhesives does not improve adhesive strength values, so it should be avoided. As a first choice, functionalsilane is recommended, and in the second degree, only use universal adhesives, but do not associate the two materials in the same adhesive process.
