ABSTRACT
The relationship between nasal and oral cavity pathologies is based on their anatomic proximity and common structures, as well as the close position of the maxillary teeth root apices to the lateral and/or rostral walls of the nasal cavity. Bleeding and a purulent, mucous, or mucopurulent character of the nasal discharge appears with all nasal problems regardless of the causative factor. Lateral projections are complementary to dorsoven- tral and V D projections. A partial frontal projection can also be obtained with an open-mouth projection, when the central beam is directed at the pharynx. The nasal cavity, due to its topography and location, is commonly affected by pathology present in the oral cavity. Radiolucent foreign bodies are not visible nor easy to diagnose until their long-term presence creates chronic inflammation and destruction of nasal structures. Diagnosis of secondary nasal issues starts with a conscious examination, but always requires a detailed examination under general anesthesia.
