Purpose: To determine the relationship between the dental root indentation
and maxillary sinusitis. Methods: We
assessed the records of the patients who underwent paranasal sinus computed
tomography imaging for suspected sinusitis. Results: We identified a total of 52 patients with a pre-diagnosis of
maxillary sinusitis. Dental indentation was detected in 58 of 104 (55.7%)
sinuses. Forty six of 58 sinuses (79.3%) with dental indentation had mucosal
thickening higher than 2 mm. The
difference between the groups was statistically significant (p=0.007). Conclusion: Dental indentation should
be kept in mind as a reason for chronic maxillary sinus inflammation, if an
underlying cause cannot be identified.
