MAXILLARY SINUS INFECTION WITH ESCHERICHIA COLI: LITERATURE REVIEW AND CASE REPORT

The maxillary sinus foreign body is a frequent consequence of accidents in dental treatments. These unfortunate events are due to the close relationship of the root tips of posterior teeth relative to the floor of the maxillary sinus. Extruded endodontic materials can act essentially as foreign bodies and potentially can lead to various pathophysiological responses. Not always produce reaction, in some cases are asymptomatic, and kept only under observation. The microorganisms isolated in patients with sinusitis of odontogenic origin differ from non-odontogenic, its predominant by anaerobic bacteria. The present case refers to accidental displacement of gutta-percha cones to the maxillary sinus; together with the presence of communication oroantral allow entry and colonization of Escherichia coli, an aggressive and rare bacteria in this location. For therapeutic treatment we did an approach through the oroantral communication, and prescribe the sultamicilin as the antibiotic.
