Invasive technique of pit and fissure sealants in primary molars: a SEM study.
One of the alternatives used when the clinical inspection of the fissure is doubtful is the invasive technique. This study used the SEM, to investigate two kinds of burs in doing the invasive technique upon primary molars, as well as to test the suitability of two kinds of sealants (with and without filler particles) to penetrate into such preparations. The points hereby tested revealed to be adequate in obtaining a minimal opening in the enamel, allowing the inspection of the fissure, and at the expense of a slight removal of dubious tissue, permitting a preparation of easy clinical performance. In regard to sealant penetration, no difference was seen between the self-cured sealant and the light-cured sealant.
