Effects of Dental Factors on Fungal Sinusitis

Abstract

<b><i>Objectives:</i></b> This study aimed to investigate the associations between dental treatments and fungal maxillary sinusitis (FMS). <b><i>Methods:</i></b> We retrospectively reviewed medical charts between July 2014 and March 2019. In total, 100 cases of FMS were included in this study. We also recruited 200 patients as a control group in the same period. Therefore, each of the FMS, chronic rhinosinusitis (CRS), and normal sinus groups consisted of 100 patients. We recorded all endodontic treatments (EDTs), tooth extractions, dental implantations, and apical lesions (ALs). <b><i>Results:</i></b> The FMS group had higher incidences of tooth extraction (49% vs. 11%, respectively) and EDT (29% vs. 16%, respectively) compared to the normal sinus group and fewer ALs compared to the CRS group (6% vs. 24%, respectively). There were significant differences between the CRS and normal sinus groups in the extraction rate (53% vs. 11%, respectively) and frequency of ALs (24% vs. 4%, respectively). The dental implantation prevalence rates were similar across all 3 groups. <b><i>Conclusion:</i></b> The rates of tooth extraction were significantly higher in the FMS and CRS groups compared to the normal sinus group. In addition, of the 3 conditions, FMS was related to EDT, and CRS was related to ALs.
