[Evaluation of the modern self-etching adhesives efficacy].
The durability of bonding efficacy of composites with hard tissues of a tooth was investigated at application of one-bottle adhesive with total etching and five self-etching adhesives. The efficiency of etching by 36% orthophosphoric acid and acid components of self-etching adhesives was estimated. The adhesion between substrate and composite was measured by method of microtensile bond strength (mTBS). The control of efficiency of etching and depth of the penetration was carried out with the confocal laser scanning microscopy. It was established, that self-etching adhesives are capable to guarantee bonding of composites with enamel and dentine at a level compared with adhesives of the 5th generation. Deep adhesives penetration in dentine tubules is not the key factor for creation of reliable bonding.
