What is odontogenic sinusitis?
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.
How is odontogenic sinusitis diagnosed?

How is odontogenic infection treated?
Penicillin-based antibiotics remain the first line for the treatment of odontogenic infections. Metronidazole is effective against anaerobic bacteria. The antibiotic doses recommended in the SDCEP’s guidance are based on the doses recommended by the British National Formulary (BNF)13 (Table 2).
What happens if tooth infection spreads to sinus?
Once you have a combined tooth and sinus infection, this can spread to your lymph nodes and your neck. From there your throat can become irritated, inflamed or even restrict breathing. These are obvious signs that a serious infection may be traveling in your bloodstream.
How is dental sinusitis treated?

What are odontogenic infections caused by?
Odontogenic infections are generally polymicrobial and from endogenous oral flora. They are mixed aerobic/anaerobic with 60% caused by anaerobic and aerobic bacteria, 35% by aerobic bacteria, and 5% by anaerobic bacteria only. Of the aerobic group, Streptococci comprise about 90% and Staphylococci about 5%.
What are the symptoms of odontogenic infection?
Signs and symptoms depend on the location of the infection. They may include fever, reduced general condition, swelling, pain upon swallowing, dysphagia, hoarseness, stridor and trismus. Swelling can lead to compression of the trachea, which can threaten airway patency.

Does sinus CT scan show tooth infection?
Introduction. Multidetector Computed Tomography (MDCT) is a widespread method for evaluating paranasal sinuses and nasal cavity in daily practice. The maxillary teeth are in field of view in a paranasal sinus CT scan and it is possible to detect dental pathologies with CT.
How do you manage odontogenic infections?
How are odontogenic infections best managed?
Penicillin in conjunction with metronidazole provides excellent bacterial coverage for most odontogenic infections and should be considered the antibiotic of choice. Clindamycin also provides excellent coverage and should be used for the penicillin-allergic patient or in the setting of penicillin failure.
Establish the severity of infection. A careful history and thorough clinical examinations are essential to determine the severity of any infection.
