This could lead to suppose that the development of a coated tongue might be enhanced by the colonization of most aggressive germs originating from dento-alveolar fistulae. The high prevalence of coated tongue found in this children's population could be attributed to low levels of oral hygiene exhibited by children belonging to this age rank and socio-economic level. These children belonged to the lower socio-economic strata of our city, which can be characterized by restricted access to health services as well as lacking motivation with respect to oral hygiene. These would all be factors to enhance residue accumulation and bacterial colonization in the dorsal surface of the tongue. In spite of differences and peculiarities exhibited by our sample.
La alta prevalencia de lengua saburral en esta población infantil se podría atribuir a los escasos niveles de higiene bucal que tienen los niños a esta edad y al nivel socioeconómico, correspondiente en este caso a los más bajos de la ciudad, caracterizado por acceso restringido a los servicios de salud y falta de motivación hacia la higiene bucal, facilitando así el acúmulo de residuos y colonización bacteriana en la superficie dorsal de la lengua.
