[Environmental pathology and dentistry. III. Carcinogenic process of the soft tissues of the oral cavity]

The context in which a relationship between environmental pathologies and dentistry is most easily distinguished is with reference to the carcinogenic processes of soft tissues in the oral cavity. In this study, a distinction is made between potentially cancerous lesions and true carcinomas, and the relationship between tumour pathology of the oral cavity and the surrounding environment is analysed. Clinical aspects are also illustrated.
