Non neoplastic tongue diseases. An epidemiological investigation and diagnostic criteria

Few clinical-epidemiological data regarding tongue diseases were showed in recent literature. The aim of this study was to evaluate the prevalence of non neoplastic tongue pathologies, and to perform an epidemiological, clinical and etiopathogenetic comparable data system on Non-Neoplastic Glossitis (NNG).

A total of 215 subjects (90 males and 125 females, age range: 6-72 years) have been examined) at the Dental Clinic of the University of Brescia over a period of 2 years. From this group, patients with tongue non neoplastic lesions were selected. Each selected patient with NNG was examined, following the Diagnostic Protocol of the "Department of Oral Pathology and Medicine" of the Dental Clinic of Brescia University.

84 cases of NNG (39%) were observed from January 1997 to October 1998.

The selected group of patients with NNG has been stratified following clinical and etiological criteria, and the results discussed, emphasizing the importance of careful and correct examination of the tongue, in order to bring to light morphological and pathological changes often neglected or misdiagnosed. One should never exclude, moreover the possibility of malignant evolution of some lingual lesions requiring a close follow-up.
