Oral Condition of Infantile Acute Lymphatic Leukemia with Microbisme Substitute

Abstract

The oral condition of a 7 year old boy at the 12th and 13th remission induction therapy sessions since contracting acute lymphatic leukemia was investigated clinically and microbiologically.
The findings obtained were as follows:
1) The appearance of gingivitis coincided with the decrease of white blood cells 7 to 9 days after administration of the anti-leukopenic drugs.
2) Gingivitis appeared on the same site of the oral cavity at both remission induction therapies sessions.
3) The bleeding from the gingival lesions corresponded to the decrease of blood platelet at both remission induction therapies sessions. Conversely, gingivitis disappeared with the improvement of peripheral blood conditions.
4) The total number of oral bacteria decreased after administration of the antibiotics, although the ratio of Candida in the oral microbial flora increased markedly.
5) Typical symptoms of oral candidiasis were not observed after the appearance of the microbisme substitute.
