When a draining lesion is encountered on the skin of the face, an endo dontic origin should always be considered in differential diagnosis. N on-surgical endodontic therapy, sometimes complimented by surgery, or extraction are the choices for the treatment of these cases. Three cas es of extraoral sinus tract on the chin caused by necrotic pulp of tra umatized lower anterior teeth are presented. A paste consisting of cal cium hydroxide and barium sulfate powder mixed with glycerin was used.
