Abstract

We treated a rare case with multiple sites of idiopathic internal resorption in primary dentition. A 3-year-old Japanese boy with no history of medical or dental disorders was referred by a general dentist for management of multiple sites of internal resorption in the primary teeth. Those with internal resorption had a pinkish color, however, no symptoms were noted. An X-ray photographic examination revealed round radiolucent lesions in the crown pulp of the upper right first primary molar, as well as in the roots of the lower right primary canine, upper left central primary incisor, and lower right lateral primary incisor. A histological examination of pulp removed from the right lower lateral primary incisor revealed increases in blood vessels, lymphocytes, and macrophages, while odontoclasts were not identified. Resorption of the teeth progressed rapidly and the lower right primary canine spontaneously exfoliated. Thereafter, endodontic treatment using Vitapex® halted the progress of tooth resorption. Our findings showed that early diagnosis, endodontic treatment, and short-interval follow-up examinations are needed to preserve teeth from rapid internal root resorption. Key words Histopathology, Internal resorption, Primary teeth.
