RESUMO
The purpose of this paper is to carry out an analysis of the term leukoplakia since its introduction in 1877 and to expose the most accepted concepts and present classification within specialists. For this purpose attention will be paid to definitions established in the international seminary developed in Malmö City, Sweden, in June 1983. A group of observations on present status of research and diagnostic methods and its limitations to pre-establish when a lesion of this type is going to evolve toward malignancy, is included. An important part of this paper is devoted to the linguistic analysis of leukoplakia and leukoplasia expressions. An extensive argumentation demonstrating the systematic impropriety in the Spanish Language of translating the English term "leukoplakia as leukoplasia, is presented. There is in Spanish the accurate translation, given by the expression leukoplakia, which is not only the adequate one for the exactness of its translation but also the one more conceptually adjusted to contemporary definition universally accepted, that is to say, a white plaque. Finally, a comment on importance of incorporates to our language the exact translation of scientific words, not only to fit it to present science, but also to a better fulfillment of its function in allowing the communication within Latin American researches themselves and with the world scientific community, is exposed.

This research was performed with the purpose of being acquainted with the frequency of onset of subprosthetic stomatitis in a large group of individuals and to determine some causal variables derivative of personal customs and habits of using prosthesis. The universe of study was represented by all the patients carrier of denture-plate for six months or more, who attended to 36 stomatologic clinics during a period of three uninterrupted weeks. A total of 6,302 individuals was examined and 2,952 of them were recorded as affected by subprosthetic stomatitis, for a rote of 46.84%; corresponding 50.47% to female sex and 39.96% to male sex. The most involved decade of life was that of 30 years, for 49.8%, and higher affection was observed in individuals using prosthesis with acrylic base, accounting for 48.45%. The largest amount of lesions, 63.04%, corresponded to clinical grade I. Of the individuals who estimated at the beginning of using fixed prosthesis, that such prosthesis were suitable and well fitted, 47.14% presented alterations. Of the individuals examined, 83.38% had the habit of sleeping with prosthesis, and 51.07% of them was affected by lesions.

In order to determine influence of habit of smoking black cigarettes on rhythm of cell maturity of the mucosa of palate and cheeks, cytologic samples of such regions were taken to 52 male individuals, who were smokers since more than five years ago, older than 40 years and who at the time of the clinical examination did not present evidences of any type of lesion. The samples were compared with those from a control group comprising non-smoker individuals, but with the same characteristics. The samples were obtained by scraping cheeks and palate with a wooden spatula, and were fixed with ethyl alcohol and stained by Papanicolaou's technique. Observations were performed at a light microscope. Microscopic fields for cell counting were selected at random. More than 300 cells per patient were evaluated taking into account their morphology and characteristics of staining affinity. Within the studied variables, that of smoking years was the most influencing on modifications of cell keratinization indexes in the buccal mucosa of healthy smokers (p less than 0.05).
