Periodontal diseases: is it possible to prevent them? A populational and individual approach.

Periodontal diseases are infectious inflammatory chronic diseases of a multifactorial nature. They are primarily caused by dysbiotic ecological changes in dental biofilm, which may be influenced by risk factors. The prevention of periodontal diseases may involve different strategies focused on reducing distal, intermediate, and proximal risk factors at both the population and individual levels.
