説明

The use of the arsenic paste on the primary teeth has been considered to be dangerous because this paste induces severe pathological changes when it is applied without correct knowledge of the effect of this material. Even today, this paste is still used for the mortal extripation of the pulp of primary teeth. In this report, we describe the case of the serious damege of a succedaneous permanent tooth which was found to be affected by the use of arsenic paste on a primary molar.<BR>A 4.5 year girl visited the Pedodontic Clinic of Osaka University Dental School Hospital complaining early exfoliation of E and alveolar bone loss.<BR>Oral examination revealed marked atrophy of the gum andO the presence of the partially erupted brown colored 5. Radiography showed a wide radiolucent area around the E lesion, and the hypominearalized rootless 5 which was located in the gum without alveolar bone.<BR>By means of X-ray fluorescence analysis, arsenic (As+++) was found in the piece of alveolar bone slab (sequester) which had been removed after the loss of E.<BR>Based on the above observation, it was diagnosed that the use of arsenic paste on E induced the formation of sequester and dameged 5.<BR>Today, approximately 2 years after the first visit, no change can be seen on the crown of 5, and radiography shows the growth of the root. However, the implanted condition of 5 is not completed.
