Acute Dentoalveolar Abscess of Sinusal Origin: an Uncommon Case Report

Abstract

Dentoalveolar abscess of sinusal origin is uncommon and may lead to an unfavorable outcome. A 25-year-old woman presented with a severe headache that had evolved approximately 5 months prior. Computed tomography analysis showed diffuse and irregular mucoperiosteal thickening of all the sinuses. After the rhinoscopy, and based on the clinical and imagological findings, the patient was diagnosed with rhinosinusopathy. Antibiotics and corticoid drugs were prescribed. One day after the rhinoscopy, the patient showed spread of the sinus infection to the dental tissues, requiring emergency dental care due to diffuse facial cellulitis and swelling associated with tooth 26. In the absence of clinical findings indicative of a carious infection, acute dentoalveolar abscess of sinus origin was confirmed; a root canal procedure was performed. After 30 days, the tomography scan showed a significant improvement of the infectious process in all the sinuses; the patient is still under follow-up.
