[An investigation into the actual condition of children with blood diseases in the pedodontic clinic of Niigata University Dental Hospital].

Children with blood diseases do not infrequently visit the dental clinics. Therefore, it is important to recognize the actual condition of blood diseases in association with the oral treatment of patients. During the period from Sept. 1979 to June 1989, 68 patients who had blood diseases visited the Pedodontic Clinic of Niigata University Dental Hospital. This report is the investigation of the dental situation of these patients. The result were as follows: 1. The ratio of patients with blood diseases in our clinic was 0.7%. The patients with leukemia were most frequent. 2. Most of the first visit-patients with blood diseases were children aged 6, while the general patients group was younger. The ages of first visit-patients corresponded to the most frequent ages of primary diseases. 3. The majority of their chief complaints were "the treatment of decayed teeth for caries". Others were "the extraction of loose teeth for exchange" or "the diseases of oral soft tissues". 4. The patients visited our clinic from all over Niigata prefecture, some of which visited from a great distance and were introduced by Niigata University Medical Hospital. 5. As to the treatment of decayed teeth for caries, the patients with hemophilia had a large number of treated teeth as compared with the other diseases. In case of leukemia, anaphylactoid purpura and idiopathic thrombocytopenic purpura (ITP), the outpatients generally tend to be subject to more severe caries than the inpatients in Niigata University Medical Hospital. 6. The percentage of recall of patients with blood disease was lower than that of general children at the rate of about 20%.(ABSTRACT TRUNCATED AT 250 WORDS)
