[Radiological semeiology of the lacunar injuries of the mandible].

The paper discusses the radiological findings in the mandibular cavities on the basis of an anatomopathological classification system and suggests some useful criteria for definitive diagnosis. It concludes by stating that it is not always possible to define the radiological findings which allow us to understand the real nature of the lesion, whereas benign or malignant characteristics are quite easily recognisable.
