Conservative management of persistent facial cutaneous sinus tract with a dental origin

Facial and cervical area sinus tracts can be odontogenic or non-odontogenic, and so clinicians should be aware that lesions with a dental origin can be confused with dermatological lesions. We describe three cases of cutaneous lesions of dental origin that were initially misdiagnosed as being dermatological in origin. Multiple unsuccessful treatments were attempted but the lesions failed to heal. However, conservative endodontic intervention resulted in complete resolution of the causative periapical lesions within a short period, making surgery unnecessary. Dental aetiology, as part of a differential diagnosis, must be considered in such oro-facial lesions.
