Hibrid layer influence in bond systems microtensile test after storage
Abstract
The aim of the present study was to evaluate the microtensile bond strength of different bond systems due to presence or absence of the collagen layer and
storage time. Therefore, 24 third molars were restored using different bond systems, with or without pretreatment with NaOCl, and stored for 24 hours and
12 months. The microtensile strength values were subjected to statistical analysis. The pretreatment with NaOCl was not significant in 24 hours. However,
this pretreatment remained satisfactory bond results after 12 months for all bond systems, except for Prime & Bond NT.
