Head And Neck Cancers
Carcinoma Of Alveolus Clinical Features
- Early invasion of bone takes place mostly via the PDL and this causes extensive mobility and premature loss of the
regional teeth. - Extraction of tooth often leads to early bone invasion,which causes non-healing or delayed healing of the extraction socket.
- Mandibular lesions often extend to the adjoining structures, e. g. labial mucosa, tongue, bone, flor of the mouth and the retromolar areas.
