１３歳男児の下がく右側第一大臼歯部歯そう骨に高度の吸収と再生が見られた一症例

Abstract

Because alveolar bone resorption is considered as one of the leading symptoms of the inflammatory periodontal disease, the regeneration of the bone after treatment is of a primary concern to peroidontists.A case of a boy in which resorption and regeneration of the bone took place within a short period of time was encountered at the authors's clinic. The patient is a 13 years old boy who has been administered Diphenyl-hydantoinate for the treatment of epilepsy since the age of 8. The bone destruction was suddenly noted on the panoramic X-ray films taken for regular check purposes, starting from the inter-radicular space to the distal root of the right mandibular first molar.Eight months after the first visit, radiograph revealed the nearly complete fill of the bone defect. The therapy performed during this period was an initial treatment of periodontal tissue including plaque control, scaling, occlusal adjustment and restoration of caries cavity of the right mandibular first molar.The possible explanation of the onset of bone destruction and regeneration was discussed.
