观察轻重程度不同的牙周炎226例,年龄21～53岁,其中有138例(61％)并发牙齿敏感症。检查患牙对酸、甜、冷、热、探触和电流刺激的反应,测量牙周骨组织吸收(牙根裸露)程度。用脱矿液在牙齿表面取硬组织标本,用标准滤纸条从牙周袋取龈液标本,测定牙齿硬组织和龈液的钙、磷、镁含量。数据进行统计学处理,分析互相之间的关系。
A total of 226 periodontitis with different severity were observed, ranging in age from 21 to 53 years. 138 (61%) had tooth-sensitivity. The responses of the affected teeth to acid, sweetness, cold, heat, sniffing and galvanic stimulation were examined and the extent of periodontal bone tissue absorption (root denudation) was measured. Using demineralized liquid to take hard tissue samples on the tooth surface, taking gingival fluid samples from the periodontal pocket with standard filter paper, and determining the contents of calcium, phosphorus and magnesium in hard tissue and gingivitis. The data were statistically processed and the relationship between each other was analyzed.
