title: Occult tooth fragments spontaneously extruded after six months.
abstract: Fracture of one or more teeth is a frequent complication of trauma to the oral cavity. Broken teeth that are not accounted for are often presumed to be swallowed or lost. We report a case of fracture of incisors that were not located on physical examination following the trauma but were discovered six months later as hard, perforating papulonodules on the lower lip.
