title: [Periodontal diseases. Clinical forms, epidemiology, etiology, prevention].
abstract: Periodontal diseases affect the teeth-supporting tissues and are the main causes of tooth loss in subjects older than 40 years. They are characterized by gingival bleeding, bone destruction and dental mobility and are due to bacterial proliferation on dental plaque and tartar. Several forms have been described according to the severity of alveolar bone destruction and to the patient's age. These diseases can be prevented by a strict bucco-dental hygiene applied jointly by the patient and the practitioner.
