Maxillary sinusitis is common due to the close anatomic relation of the frontal sinus, anterior ethmoidal sinus and the maxillary teeth, allowing for easy spread of infection. Differential diagnosis of dental problems needs to be done due to the close proximity to the teeth since the pain from sinusitis can seem to be dentally related. [ 1 ]
Dental conditions such as gum disease, periapical abscesses, or tooth decay can lead to odontogenic sinusitis. Similarly, dental procedures such as tooth extractions, implant placement, or root canal treatments, particularly if they involve the posterior maxillary teeth, can also cause this condition.
Maxillary sinuses are more radiolucent than orbits. Maxillary sinusitis [2] Differentiating pathology in maxillary sinus. Maxillary sinus shows radiopacity. [2] Mucous membrane shows thickening. [2] Air-fluid level may be observed if the radiograph is taken in "head-up" position. [2] It is not seen in radiograph taken in lying down position.
The cause of this situation is usually a periapical or periodontal infection of a maxillary posterior tooth, where the inflammatory exudate has eroded through the bone superiorly to drain into the maxillary sinus. [59] An estimated 0.5 to 2.0% of viral rhinosinusitis (VRS) will develop into bacterial infections in adults and 5 to 10% in ...
Odontogenic sinusitis is an inflammatory condition of the paranasal sinuses that is the result of dental pathology, most often resulting from prior dentoalveolar procedures, infections of maxillary dentition, or maxillary dental trauma. [6] Infections associated with teeth may be responsible for approximately 20% of cases of maxillary sinusitis ...

Recent studies have classified two types of maxillary sinus septa: primary and secondary. Primary septa are those initially described by Underwood and that form as a result of the floor of the sinus sinking along with the roots of erupting teeth; these primary septa are thus generally found in the sinus corresponding to the space between teeth, as explained by Underwood.
