O b j e c t i v e s: To identify tooth diseases as potential causative
factors in the development of maxillary sinus lesions, with the aid of
clinical examination combined with Cone Beam Computed Tomography (CBCT),
in the patients with persistent sinus-like ailments, unresponsive to
routine treatment offered by otolaryngologists.
M a t e r i a l s a n d M e t h o d s: In 44 patients with suspected
odontogenic maxillary sinusitis, a dental examination with tooth
vitality test was carried out, in conjunction with CBCT. The study
involved 29 women and 15 men (age range 19–69 years, mean age 43 (SD =
R e s u l t s: In 15 (34.1%) patients the odontogenic lesions were
encountered in maxillary sinuses. A total of 33 causative teeth were
identified, of which 13 (39%) were after root canal treatment (RCT).
Only one of the teeth had a properly reconstructed crown, and only one
tooth had the root canals properly filled-in. Most frequently, the
lesions in the sinuses were attributed to the inflammation of periapical
tissues; the first molar having been established as the most common
C o n c l u s i o n s: A detailed dental examination, pursued in
conjunction with CBCT analysis, allow to diagnose odontogenic maxillary
lesions. The incidence of long-term ailments originating in the
maxillary sinuses should prompt a detailed assessment of the teeth,
especially those after RCT.
