Abstract

SABOIA, Vicente de Paulo Aragão; SAITO, Solange Katia  and  PIMENTA, Luiz André Freire. Micromorphologic aspects of the adhesive interface in function of variation in the specimen manufacturing. Pesqui. Odontol. Bras. [online]. 2000, vol.14, n.4, pp. 340-344. ISSN 1517-7491.  http://dx.doi.org/10.1590/S1517-74912000000400006.

The aim of this study was to demonstrate the different micromorphologic aspects of the adhesive interface, which can be observed in fragments of the same specimen in function of variations during the processing for scanning electron microscopy. Resin blocks were cemented on the dentin of the occlusal surfaces of recently extracted third molars and were longitudinally sectioned for observation through SEM. The results showed wide variation in the direction and length of tags. There is need for standardization of the angulation with which the specimens are cut, so as to avoid mistakes in the analysis of the penetration efficacy of adhesive systems.
