[Observations on the frequency of neoplasms and inflammatory processes of the oral cavity during the period from 1961 to 1970 (author's transl)].
The Authors carried out a clinical and statistical study of the frequency of malignant and benign neoplasms, inflammatory processes and pre-cancerous states in the mouth over the period from 1961 to 1970, comparing their findings with those provided by a previous investigation covering a similar period of time. Benign tumours appear to be more frequent than malignant ones, and the latter are found most frequently in males in their fifties. The most frequent site of malignant tumours is the lower lip, and histologically they are mainly found to be epithelial.
