Abstract:

Background: Odontogenic maxillary sinusitis is an inflammatory process of dental origin, localized in the maxillary cavity with all the characteristic manifestations of inflammation. The diagnosis is made on the basis of medical history, objective examination and paraclinical examinations (radiography, computed tomography, pulp vitality test).

Case report: The patient is a 33-year-old man with odontogenic maxillary sinusitis. In addition to the medical history and the clinical examination, paraclinical examinations are used during the diagnostic process: thermovisiography, orthopantomography, periapical radiography, pulp vitality test and computed tomography.

Conclusion: Chronic periodontitis of the mediovestibular canal of tooth 26 has been identified as the etiological cause of the condition. In addition, we found resorptive changes and a foreign body; secondary caries and a lack of canal filling material in tooth canal. The algorithm we used,for the paraclinical examinations, started from the most non-invasive and continue to the more severe ones in order to maximally spare the patient’s health during the diagnostic process.
