The close co-operation of rhinologists and dentists is needed for the diagnosis of dental sinusitis.
To evaluate the pathological condition, rhinologists are required to have a basic knowledge of odontology.
We described the value of the intraoral roentgenograms in the diagnosis of dental sinusitis. Intraoral roentgenograms are most important in understanding the changes in teeth and surrounding structures in patients with dental sinusitis.
The changes of teeth, supporting structures and floor of maxillary sinus could be classified as follows:
1. Standard type
2. Lower type
3. Lower type of apex area
4. Lower type of interradicular area
5. Indistinct type
6. Absorption type.
