Management of periodontal infection leading to mandibular extra-oral sinus in 13-year-old male

Abstract

Cutaneous sinus tract of odontogenic origin is the most common among the various types of sinus tracts which are formed on the face and neck. Cutaneous sinus tracts may develop from local chronic osteomyelitis. Although the causative factor is generally periapical infection of odontontogenic origin, they are rarely of periodontal origin. This paper describes a case of the mandibular extraoral sinus of periodontal origin in 13yearold boy, in whom the condition arose following periodontal infection in relation to permanent mandibular left second molar with probing pocket depth 10 mm distobuccally. The source of infection was associated with developing the third molar which had no visible communication with the oral cavity. The case was managed by removal of the source of infection with periodontal treatment.
