Descrição: dc.descriptionThis case report describes the resolution of a 20-year misdiagnosed nasal sinus tract after root canal therapy with multiple sessions of calcium hydroxide (Ca[OH]2) intracanal medication. Clinical evaluation, including diagnostic testing and sinus tract tracing, was performed followed by a cone-beam computed tomographic scan and 3-dimensional reconstruction of the apical lesion. Bacteria and endotoxin analyses were performed from the nasal sinus tract and paired root canal infection before (s1) and after instrumentation (s2) and after 7 (s3), 14 (s4), and 21 (s5) days of Ca(OH)2 medication. The bacteria analysis was performed using the checkerboard DNA-DNA hybridization method and endotoxin quantified by the limulus amebocyte lysate method. A similar microbiota profile was found in the sinus tract and paired root canal infection. No target bacterial species were detected in the root canal at s2, s3, and s5. In contrast, Actinomyces israellii and Eubacterium nodatum were detected at s4. Differences in bacterial detection were found between s1 × s2, s3 × s4, and s4 × s5 (all P <.05). Endotoxin was detected in the root canal at all sampling times. Differences in the levels of endotoxin were found between s1 × s2, s2 × s3, and s3 × s4 (all P <.05).The bacterial analysis revealed similar microbiota profiles present in the nasal sinus tract and paired root canal infection with the participation of a wide variety of gram-positive and -negative species. Additionally, root canal therapy with multiple sessions of Ca(OH)2 intracanal medication for 21 days was effective in disinfecting the root canal system and resolving the nasal sinus tract.-
