Purpose: to investigate if the addition of a cotton "swab" to the Ayre spatula and its previous moistening with physiologic saline solution increase the obtention of endocervical cells in colpocytologic smears. Methods: a random and single-blind diagnostic study was performed, involving three techniques of collection (Ayre spatula, combination of Ayre-dry cotton swab spatula and combination of Ayre-moist cotton swab spatula). A total of 307 smears prepared by Medicine students and residents of Gynecology and Obstetrics were evaluated. Results: there was no significant increase in the number of endocervical cells (columnar and/or metaplastic), obtained with the addition of dry swab (p = 0.2) or with the addition of a moistened swab (p = 0.8). Conclusions: the author concluded that mainly when the collections were performed by trainee professionals and in the absence of other more effective endocervical collecting device, it is more economical to use only the Ayre spatula to prepare the smear.
