Summary
Introduction: The specific structure of enamel fissures of molar teeth requires pre-treatment before a sealant can be effectively applied.
Material and methods: The air abrasion technique is gaining acceptance for this purpose. This study was undertaken to examine the effect of air abrasion on the shape and surface of fissures at three levels (entry, middle part and fundus).
Results: Compressed air mixed with aluminum oxide particles resulted in enlargement of the fissure. Microretention sites in the form of pits and hollows were discovered at all levels studied.

K e y w o r d s: scanning electron microscopy – air abrasion technique.
