Laser Assisted Treatment of Extra Oral Cutaneous Sinus Tract of Endodontic Origin: A Case Report

Mohammad Asnaashari, Sajedeh Ghorbanzadeh, Saranaz Azari-Marhabi, Seyed Masoud Mojahedi



Introduction: Sinus tracts (or fistulas) are a common manifestation of pulpal necrosis that requires conventional or rarely surgical- endodontic treatment in order to heal. They are mainly identified intraorally and in rare cases they manifest extraorally which may frequently be misdiagnosed and incorrectly treated. New technologies such as lasers have been developed as adjuncts to standard endodontic antimicrobial procedures in order to increase the success rate of endodontic therapy and complying the desire of saving a natural tooth.

Case presentation: Herein, we present a clinical case of extra oral sinus tract with Periodic pus drainage that was successfully treated by combining   conventional endodontic therapy, intra canal PDT and extra oral low level laser therapy.

Results and conclusion: Treatment of the odontogenic lesion among with the extra oral lesion was an ingenious and successful technique which was achieved by laser technology and winded up to patient’s consent and satisfactory results of treatment.
