Persistent bacterial colonization of <i>Porphyromonas gingivalis</i>, <i>Prevotella intermedia</i>, and <i>Actinobacillus actinomycetemcomitans</i> in periodontitis and its association with alveolar bone loss after 6 months of therapy
These data indicated that, in this population, the presence of P. gingivalis in plaque after treatment might be indicative of progressive alveolar bone loss.
