The role of bacteria in periodontal diseases.
The dental literature contains ample scientific data supporting the concept that periodontal diseases are infectious diseases. The formation of plaque on and around the teeth represents a massive accumulation of bacteria that are usually present in the oral cavity. This bacterial colonization is relatively independent of food intake, degree of salivation, mastication, or malocclusion.Although experimental studies have not defined the group of bacteria or a specific pathogen that is responsible for chronic gingivitis, it is known that the suppression of plaque is consistent with dental and periodontal health. It has been demonstrated that good oral home care combined with professional cleaning and/or the use of antimicrobial compounds can control dental plaque.In order to take full advantage of existing knowledge on dental care, it is necessary both to persuade the public to avail itself of the remedies available and to carry the message to practising clinicians, dental school staff, and dental scientists. The knowledge and techniques necessary to control plaque are available and, if applied collectively, can ensure the retention of the dentition throughout the life of the individual.
