Odontogenic sinusitis is a type of sinusitis (inflammation of the sinuses), specifically caused by dental infections or procedures. [1] Comprising approximately 10-12% of all chronic sinusitis cases, this condition primarily affects the maxillary sinus , which is in close proximity to the upper teeth .
Infections associated with teeth may be responsible for approximately 20% of cases of maxillary sinusitis. [7] 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.
This can be caused by tooth decay, broken teeth or extensive periodontal disease (or combinations of these factors). A failed root canal treatment may also create a similar abscess. A dental abscess is a type of odontogenic infection , although commonly the latter term is applied to an infection which has spread outside the local region around ...
By definition, chronic sinusitis lasts longer than 12 weeks and can be caused by many different diseases that share chronic inflammation of the sinuses as a common symptom. It is subdivided into cases with and without polyps. When polyps are present, the condition is called chronic hyperplastic sinusitis; however, the causes are poorly ...
There are two other ways anaphylaxis can kill besides airway constriction: a sudden drop in blood pressure that causes a heart attack, or else a person could lose consciousness and inhale their ...

Very rarely, toothache can be psychogenic in origin. [10]: 57–58 Disorders of the maxillary sinus can be referred to the upper back teeth. The posterior, middle and anterior superior ...
Dental caries can also cause bad breath and foul tastes. [16] In highly progressed cases, an infection can spread from the tooth to the surrounding soft tissues. Complications such as cavernous sinus thrombosis and Ludwig angina can be life-threatening. [17] [18] [19]
An oroantral fistula (OAF) is an epithelialized oroantral communication (OAC), which refers to an abnormal connection between the oral cavity and the antrum. [1] The creation of an OAC is most commonly due to the extraction of a maxillary tooth (typically a maxillary first molar) which is closely related to the antral floor.
