Periodontal diseases are a group of related inflammatory disorders, initiated by dental plaque and causing destruction of the supporting structures of the teeth. Although the inflammatory response is a fundamental defence mechanism against bacterial infection, its persistence over a long period of time may extensively damage the periodontal tissues: cementum, alveolar bone, periodontal ligament and dentogingival tissues. These disorders, despite recent improvements in oral health are still a major cause of tooth loss in patients over 35 years of age.
牙周疾病是一组相关的炎症性疾病,由牙菌斑引发,会导致牙齿支持结构的破坏。尽管炎症反应是抵御细菌感染的基本防御机制,但其长期持续可能会广泛损害牙周组织:牙骨质、牙槽骨、牙周韧带和牙龈组织。尽管近期口腔健康状况有所改善,但这些疾病仍是35岁以上患者牙齿缺失的主要原因。
