Abstract
We experienced a case with continuous gingival bleeding caused by steel crowns with extremely poor marginal adaptation in a 5 year 4 month thrombasthenial boy. The patient experienced gingival bleeding which continued for 8 days in spite of transfusion of PC and pressure hemostasis with bosmin gauze, and was referred to our hospital for treatment.
The gingival bleeding was seen from the cervical area of the lower right primary molars having extremely poor cervically adapted steel crowns. The steel crowns were removed and the gingival area was rinsed carefully with acrynol solution. The bleeding was then easily stopped and has not occurred since.
All dental treatment was performed under AMCA control (1200 mg/day)and PC was not transfused while he was in the hospital for 6 days.
Three primary molars were extracted under local infiltration anesthesia and sutures, surgical packs, and acrylic sprints were used to control bleeding. Adequate hemostasis resulted three hours after the extraction and the acrylic sprints were removed.
Pulp and root canal therapies were applied to three primary molars and crown restrations were applied to seven primary teeth.
A denture-type removable appliance was applied to the extracted mandibular first primary molars portion. Since the space closure occurred after the extraction, the removable orthodontic appliance was applied to the extracted maxillary second primary molar portion when the eruption of the maxillary first molar was finished.
