Das chronisch-mechanische Trauma als wesentlicher Kofaktor in der Ätiologie von Mundhöhlenkarzinomen

Summary

In our series of 140 carcinomas of the oro-pharyngeal region smoking, alcohol abusus and diminished care of oral hygiene were obvious cofactors of cancer etiology. Most tumours were found in the lower social class. In contrast to other findings in the literature chronic mechanic trauma was frequent in our patients, resulting from sharp rests of teeth, insufficient conservation, or malfitting prosthesises. The epithelial lining showed, according to the clinical findings, histological inflammation, hyperkeratosis, carcinoma in situ or even growth of carcinoma. Therefore, optimal prosthesises and oral hygiene are important factors in the prevention of carcinomas of this region.
