Non-surgical Management of a Facial Sinus Tract Originated from the Maxillary First Molar Periapical Infection: a Case Report.

Abstract

The diagnosis of a facial sinus tract caused by periapical infection remains difficult due to the wide range of potential aetiologies. The canine is the only maxillary tooth that has been reported to serve as the source of infection for a facial sinus tract. The scenario encountered in the present case was extremely rare as the facial sinus tract was caused by the maxillary molar. The buccal alveolar bone of the maxillary right first molar had been destroyed due to periodontitis and aberrant occlusal force, which caused a periapical abscess in the maxillary right first molar site and ultimately drained extraorally. The purpose of this case report is to illustrate the potential for a periapical lesion of the maxillary molar to induce facial sinus tracts and propose a non-surgical therapeutic approach for such cases.
