Abstract :

Adhesive systems in dentistry, are constantly in a process of change in order to reduce problems of recurrent caries such as prolonging dental treatments of minimally invasive enamel, therefore the combination of different materials and techniques to potentiate this effect has emerged. Phosphoric acid has traditionally been used, and the air aasion system has currently been implemented which is aluminum oxide particles applied by pressure. This paper evaluates microscopically etched enamel whether this tissue with the combination of phosphoric acid and air aasion increases. It is then that 30 randomly premolars were used, and three study groups: group A was formed with 10 samples that were etched with 37% phosphoric acid for 15 seconds and was the controlled group; 10 samples of aasive air with particles of 25 microns for 30 seconds were applied to group B and acid etching and application of air aasion; in the same conditions as above, it was performed to group C which were observed trough the metallographic microscopic (Carl Zeiss) at 500X and analyzed by the AnalySIS software. Group A showed an engraved Type III; Group B presented an engraved Type I, and Group C presented an engraved Type III. Through the present study it was demonstrated that the combination of microscopically air aasion and phosphoric acid, a dominant etching uniformity pattern is obtained, this leads to generate greater mechanical lock that can ensure durability in adhesive dental restorations with greater preservation of tooth enamel.
