ABSTRACT

For centuries, mouthwashes have been used in order to provide us with oral health or cosmetic benefits. Nowadays, in most countries, there is a variety of formulas available for the general public in the form of products which may require prescription or not. Alcohol is used in mouthwashes as a solvent of other ingredients and as a preservative of the preparation. For years, different formulas of mouthwashes have been used, however, the question about its alcohol content being a threat for health or not has recently appeared. The high quantity of alcohol in some mouthwashes combined with the fact that they keep in contact with the oral mucosa for much more time than alcoholic drinks, can make us think about a harmful effect from a local mechanism. Mouthrinses increase the time of the mucosa being in contact with alcohol and it has been proved that those with a high content of alcohol do cause hyperkerastosic lesions both in human beings and laboratory animals. At the moment and with the data we have, it has not been possible to establish a causal relationship between the use of alcohol-containing mouthwashes and the development of oral cancer. There is neither an evidence of the fact that alcohol increases the effects of antiplaque agents in mouthwashes.

ABSTRACT

El consuno de bebidas alcohólicas se encuentra asociado desde un punto de vista epidemiológico con un riesgo aumentado de desarrollar cáncer del tracto gastrointestinal superior. La realización de estudios que establezcan esa asociación resulta complicada, debido tanto a la confluencia de varios factores de riesgo en una misma persona, por ejemplo alcohol y tabaco, como a la falta de datos que puedan ser comprobables por el clínico. Por ello no se conoce con exactitud cual es el mecanismo patogénico responsable de este aumento de riesgo, ya que el etanol per sé no ha demostrado ser carcinógeno. Se han propuesto distintas hipótesis que tratan de explicar como el etanol, ya sea por vía local o sistémica puede actuar como factor de riesgo en el desarrollo de un cáncer oral. Este trabajo supone una revisión de la situación actual de los potenciales mecanismos patogénicos, dividiéndolos en efectos locales y sistémicos. Dentro de los primeros se hace especial referencia a la alteración de la permeabilidad de la mucosa oral, a la acción del acetaldehído y al papel de los retinoides (AU)
