This article tries to summarize current knowledge about the matters of glosso- and stomato- dynia. The term of glossodynia does not include only primarily unpleasant feeling but also all states where "at first sight" there is not clear cause of the complaints in oral cavity.
It is a multifactorial disease whose only common sign is the unpleasant feeling in oral cavity and, therefore, it is very difficult to set some classification or particular uniform procedure of examination and treatment. The aim is to concentrate on the diagnoses which are necessary to distinguish from primary dynia.
To eliminate wrongly determined diagnosis which could participate in formation and development of dynia, interdisciplinary cooperation will always be needed.
