Chronic Maxillary Rhinosinusitis of Dental Origin: A Systematic Review of 674 Patient Cases

<table><i>Aetiology of odontogenic CMRS.</i> The main cause of odontogenic CMRS is iatrogenic and accounts for 65.7% of cases. Apical periodontal pathologies (including apical periodontitis, apical granulomas, and odontogenic cysts) and marginal periodontitis follow them and account for 25.1% and 8.3%, respectively. Peri-implantitis, ectopic tooth, and odontoma remain rare causes of odontogenic CMRS.</table>
