Variazioni nelle cellule superficiali della mucosa orale nelle donne adulte, in rapporto al ciclo sessuale ed alle modalita‘ del prelievo.

Changes in the superficial squamous cells of oral tnucosa in adult women during the menstrual cycle and in dependence of the method of prelevation. The AA. execute the smears of the oral superficial squamous cells on 33 adult sound women, during the estrogenic and during the progestinic phase of the cycle; on the smears stained with Papanicolau's method, the AA. eximate the percentage of acidophilic cells (Acidophilic Index = A.I.) and of pyknotic cells (P.I.). The material was prelevated with three methods: 1) rinse of the mouth with 10ce of physiological solution and collection of the centrifugate; 2) light touch and roll with a cotton fioc on the oral mucosa and immediately execution of the smears; 3) scraping with a wooden spatula, after rinse of the mouth. The A.I. is high (average 76,94) at the 11°-14- day of the cycle and low at the 21°-25° day (average 52,52); at the same periods, the P.I. is higher (average 22,6) at the second week that at the forth week (average 8,52). On the basis of statistics calculations the AA. conclude that a significant diffe¬rence exists between the index of the two periods examinated and therefore the oral mucosa desquamates parallels at the vaginal epitehum but with a lower P.I. The method of prelevation is important because it must be executed always with the same mode, between those it is preferible the touch with cotton fioc or the rinse of the mouth
