ODONTOGENIC MAXILLARY SINUSITIS IMPROVED BY THE USE OF MINERAL TRIOXIDE AGGREGATE UNDER MICROSCOPIC OBSERVATION: A CASE REPORT

抄録

Distinguishing between odontogenic and rhinogenic maxillary sinusitis is still not an easy task. It is also not uncommon to make a quick decision to treat suspected odontogenic sinusitis by extraction, based on factors such as the size of the radiolucency. A case of a patient diagnosed with rhinogenic sinusitis who did not respond to drug treatment or endoscopic sinus surgery at an ear, nose, and throat clinic, but who recovered well after root canal treatment of the right first premolar using mineral trioxide aggregate under microscopic observation is reported.
