Changes in oral microflora after full-mouth tooth extraction: a prospective cohort study.

摘要

Full-mouth tooth extraction significantly changes the oral microflora. These changes include reduction of A.?actinomycetemcomitans and P.?gingivalis, frequently to levels below detection threshold. In some patients, A.?actinomycetemcomitans and P.?gingivalis can persist in the edentulous oral cavity up to 3?months after full-mouth tooth extraction.
