[Candida colonization in diseases of the oral mucosa: clinical observations].

The influence of Candida colonization of the oral mucosa in cases of diseases such as lichen planus mucosae and pemphigus vulgaris is demonstrated. Those colonizations which are not clinically evident may easily be overlooked. They may be one of the reasons why the treatment of the underlying diseases appears to be not effective. Repeated cultural investigations of yeasts in those diseases are necessary, especially during their sometimes prolonged therapy.
