Management of Endodontic Disease for Odontogenic Sinusitis

Abstract

Primary dental treatments for odontogenic sinusitis (ODS) due to endodontic infections (pulpal necrosis and apical periodontitis ± periapical abscess) include extraction and root canal treatment (RCT). Published evidence is lacking on the success of primary endodontic treatment for purulent ODS, with the majority of RCT-related series reporting on its success at resolving reactive maxillary sinus mucositis. Dental extraction is the most definitive treatment of endodontic disease causing ODS, but compromises the functional dentition and still often fails to resolve the purulent sinusitis. This article highlights key concepts of RCT and dental extraction techniques, as well as their published success at resolving ODS.
