“蛀牙”即龋齿,是指牙齿在以细菌为主的多种因素影响下,牙体发生慢性、进行性破坏。龋齿是多因素疾病,主要包括三个方而:细菌、饮食、唾液,这些细菌与唾液中的粘蛋白和食物残屑混合在一起,牢固地粘附在牙齿表面的窝沟中,这种粘合物叫做牙菌斑。牙菌斑中的大量细菌产生酸,造成菌斑下面的釉质表面脱钙、溶解,最终形成“蛀牙”。“蛀牙”是不会自行愈合的,如不及时治疗可继发牙髓炎、根尖周炎,引起牙齿剧痛,最终导致牙齿丧失、咀嚼效率降 “Tooth decay ” that dental caries, refers to the teeth in a variety of bacterial-based factors under the influence of chronic, progressive destruction of the tooth. Dental caries is a multifactorial disease consisting mainly of three things: bacteria, diet, saliva, which are mixed with mucins and food debris in saliva and firmly adhere to the pit of the tooth surface The compound is called plaque. A large number of bacteria in the plaque produce acid, causing the surface of the enamel below the plaque to decalcify and dissolve, eventually forming a “tooth decay”. “Tooth decay ” will not self-healing, if not treated secondary to pulpitis, periapical periodontitis, causing severe pain in the teeth, eventually leading to loss of teeth, chewing efficiency
