Abstract
A case of an 11-year-old girl with intensive gingival swelling due to a raducular-gingival groove was presented. Gingival swelling was localized at the distal gingiva of the mandibular lateral incisor. Roentogenographic examination revealed a vertical radiolucent line from the cingulum to the apex of the affected tooth. Irrigation and general and local prescription of antibiotics made the lesion noninflammatory. The intensive swelling, however, was persistent, and the affected gingiva was excised under infiltration anesthesia. The histopathological appearance exhibited a great deal of neutorophils and plasma cells, which were diagnosed as epulis granulomatosa. After the wound healed, examinationing by probe on the surface of the root of affected tooth indicated the presence of developmental groove. CT image, moreover, exhibited a groove-like structure at the middle of the root at the affected tooth. Taken together, these clinical symptoms and examinations, and the presence of radiculargingival groove of the mandibular left lateral incisor caused intensive gingival swelling.
