Abstract
When a draining lesion is encountered on the skin of the face, an endodontic origin should always be considered in differential diagnosis. Non-surgical endodontic therapy, sometimes complimented by surgery, or extraction are the choices for the treatment of these cases. Three cases of extraoral sinus tract on the chin caused by necrotic pulp of traumatized lower anterior teeth are presented. A paste consisting of calcium hydroxide and barium sulfate powder mixed with glycerin was used. Usage of calcium hydroxide paste was advocated for rapid and successful treatment of extraoral lesions communicating with necrotic teeth.
