The therapeutic effect on 76 oral phlegmon cases was investigated from the view point of the treatment factors. The results were as follows:
1) The difference of treatment period between the cases who had single antibiotic therapy and the cases who had combination chemotherapy was not found. Among the single antibiotics therapy group, the treatment period tends, to be prolonged for the cases who were administered CEPs III antibiotics compared to PCs or CEPs I and CEPs II .
2) Streptococcus sp. was isolated in high frequency from the pus of the closed abscess. Even the same causative organisms, the treatment period was different on each case.
3) The surgical drainage was performed in 28 out of 76 cases (36.8%) . The timing of the surgical procedure from the onset tends to effect the treatment period, however, the longer the time from the onset to the first visit, the longer the treatment period lasted. Therefore, the contents of the treatment before the first visit would be important factors for resistant cases.
