“…En referencia a otras formas de consumo de tabaco, estudios realizados en deportistas y otros grupos, relacionan el consumo de diferentes formas de rapé y de tabaco masticable ("tabaco sin humo" en la literatura anglosajona) con una mayor prevalencia de leucoplasia oral (Roed-Petersen et al, 1973). Trabajos realizados en USA han demostrado un vínculo positivo entre el tabaco sin humo y el cáncer de encía, vestíbulo bucal y mucosa yugal (Win et al, 1981;Wisnieswski and Barolucci, 1989). Sin embargo, estudios realizados en Suecia no encuentran esta correlación, atribuyéndolo a una diferente composición del tabaco empleado, sobre todo en lo referente a la concentración de N-nitrosaminas (Larson et al, 1991).…”

La leucoplasia oral. Su implicación como lesión precancerosa AVANCES EN ODONTOESTOMATOLOGÍA/33 RESUMEN La leucoplasia es definida actualmente en base a un concepto esencialmente clínico. En este sentido, se propone un diagnóstico provisional de leucoplasia basado en criterios clínicos y un diagnóstico definitivo para el que se requiere la eliminación de los factores etiológicos y, ante lesiones persistentes, el examen histopatológico. La consideración de la leucoplasia como lesión precancerosa proviene esencialmente de los estudios de seguimiento en los que se constata su transformación maligna. Pese a que el diagnóstico de displasia es esencialmente subjetivo y a la existencia de algún trabajo reciente que no encuentra relación entre ésta y la evolución posterior de las leucoplasias, la presencia de displasia epitelial en el examen histológico se considera actualmente como el indicador más importante de una mayor probabilidad de transformación maligna de la leucoplasia. Entre otros factores relacionados con un peor pronóstico se consideran el que se trate de una leucoplasia idiopática, las formas clínicas no homogéneas, la localización en cara ventrolateral de la lengua y suelo de boca y un tamaño mayor de 1 centímetro.Palabras clave: Leucoplasia, precáncer oral, lesión precancerosa, displasia epitelial, pronóstico. SUMMARYThe current definition of leukoplakia is based on an essentially clinical concept. Therefore, both a provisional diagnosis of leukoplakia based on clinical criteria and a definite diagnosis for which etiological factors need to be eliminated and, should there be persistent lesions, a histological examination is required, are accepted. Follow up studies in which a malignant transformation has been observed have resulted in leukoplakia being considered as a precancerous disorder. Despite the fact that the diagnosis of dysplasia is subjective and certain recent studies have not found any association between this and the development of leukoplakia, the presence of epithelial dysplasia in the histological examination is currently considered to be the most important indicator of a higher possibility of malignant transformation of the leukoplakia. Among other factors that may indicate a worse prognosis are: if the leukoplakia is idiopathic, if clinical forms are non-homogenous, if it is located on the ventrolateral side of the tongue and the floor of the mouth, and if it is over 1 cm. (0.40 inches) in size.

Background. The widespread use of smokeless tobacco (ST) has prompted concern in regard to the development of oral lesions in long‐term users. Methods. For inclusion in the current study, a subject must have used an ST product, either snuff or chewing tobacco, for at least 6 months. The subjects were recruited by advertising, and none was referred for the evaluation of an oral lesion. The following were performed on all subjects: assessment of exposure to ST, cigarettes, and alcohol; examination of the oral cavity; a biopsy, if an oral lesion was found; and analysis of a blood sample for beta‐carotene. The dietary intake of most of the subjects was analyzed. Results. Of the 347 ST users, all of whom were white male subjects, 45 (13.0%) had an oral lesion. Thirty‐five of the lesions were hyperkeratosis and 10 were epithelial dysplasia. Conclusions. Snuff exposure was associated significantly with the presence of an oral lesion (P < 0.0001). A decreased vitamin C intake also was found among the ST users with oral lesions (P < 0.01). The ST users with epithelial dysplasia, as compared with those with hyperkeratotic lesions, were slightly older, had a lower intake of vitamin C (P < 0.05), and were more likely to have used chewing tobacco than snuff.
