Non surgical management of misdiagnosed odontogenous sinus tract to chin: Case series

The purpose of this article is to present conservative nonsurgical successful endodontic treatment of an odontogenic cutaneous sinus tract with exuberant extraoral granulation tissue .This case report emphasises the need for more awareness in differential diagnosis of extraoral sinus tracts by dermatologists and other medical practitioners. In the case of a single chronic suppurative or nodulocystic facial lesion, a dental clinical examination as well as a radiological assessment of the maxillary and mandibular dentition should be performed to exclude any odontogenic origin thus preventing unnecessary multiple antibiotic and surgical interventions. Antibiotic therapy should never be administered without diagnosis of the underlying dental cause. Conservative non-surgical endodontic therapy may be the choice for an extraoral sinus tract of endodontic origin.
