Persistence Patterns of <i>Porphyromonas gingivalis, Prevotella intermedia/ nigrescens,</i> and <i>Actinobacillus actinomycetemcomitans</i> After Mechanical Therapy of Periodontal Disease

Abstract

If, after standard mechanical periodontal therapy, a large number of sites continue to bleed, one may expect an increased number of sites positive for P. intermedia/ nigrescens. If many deep pockets persist, a greater number of P. gingivalis-positive sites can be expected.
