Different biofilm models have been introduced to evaluate periodontal therapy. Rarely, single species biofilms (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis) are used. More often a mixture of defined bacteria (2–40 different species) is cultured on polystyrene or HA surfaces coated with saliva or serum. Microcosm biofilms originate from supra- and subgingival plaque or from saliva (Table 4).
