A case of fibrosis in the cheek of a 42-year-old woman is presented. The panoramic radiograph showed a well-defined, round radiopacity in the maxillary right third molar region. Other techniques revealed that it was a superimposition. The lesion was hard and painless and associated with hypertrophic scarring secondary to a burn injury many years earlier. Clinicians must be aware of the radiologic image of this fibrosis, so as not to confuse it with other radiopaque lesions of hard tissue origin that occur in both arches. A differential diagnosis is described. Keywords: calcified tissue, fibrosis, hypertrophic scar
