在创伤性牙合的病例中,咬合创伤引起的疾病包括慢性根尖周炎,因致病的因素来源于过大的牙合力对于牙齿根尖周围的损伤,使根尖周膜感受器痛觉敏感。临床症状有叩痛明显,患者不敢用患牙咬物,病程越长,对根尖周围组织创伤越重。但区别于牙髓感染和化学刺激为病因引起的各型急慢性根尖周炎,创伤性根尖周炎病例中牙齿冠髓及根髓无感染,牙髓活力可表现正常。另外,其他因咬合创伤引起的牙隐裂以及后牙纵折、斜折,伴有牙合创伤的牙周炎
In the case of traumatic occlusal occlusion, diseases caused by occlusal trauma include chronic apical periodontitis due to pathogenic factors derived from excessive occlusal force damage to the periapical apices and pain sensitivity of periapical membrane receptors. Clinical symptoms of percussion pain was obvious, the patient did not dare to use bitten teeth, the longer the duration, the more severe periapical tissue injury. However, different from dental pulp infection and chemical irritation caused by the various types of acute and chronic apical periodontitis, traumatic apical periodontitis cases of coronal pulp and root pulp without infection, pulp activity can be normal. In addition, other due to occlusion trauma caused by occlusion of the teeth and longitudinal fold, oblique fold, with periodontitis traumatic occlusion
