确切的掌握牙髓炎症的情况是很困难的,但是,为了进行更适当的牙髓治疗,需要客观的诊断牙髓状态。因此,我们把进行牙髓切断治疗的乳牙做为对象,通过对乳牙牙髓炎的血液检查,进行鉴别诊断。对象:2岁9个月至11岁2个月,平均年龄4岁11个月,患龋而无其它疾病的健康儿童36名,经临床诊断需要进行活髓切断治疗的乳牙龋齿50个,其中第一乳磨牙23个,第二乳磨牙27个。方法:常规开髓,采血涂片进行姬姆萨氏染色。在光学显微镜下进行白细胞计数,分类计数百分比。另一方面,在采血后尽可能的把冠髓取出,进行固定、包埋、切片、HE染色,制作组织标本进行镜检。病理组织炎症程度分为:无炎症(—),轻度局限性炎细胞浸润
It is very difficult to grasp the condition of pulp inflammation accurately, but in order to conduct more appropriate endodontic treatment, it is necessary to objectively diagnose the status of pulp. Therefore, we performed primary endodontic treatment of primary teeth as the object, through the blood examination of primary teeth pulpitis, differential diagnosis. Subjects: 2 years old 9 months to 11 years old 2 months, mean age 4 years and 11 months, 36 healthy children with caries and no other diseases, 50 cases of deciduous caries requiring vital pulp cutting after clinical diagnosis, among which 23 first molars, 27 second molars. Methods: Conventional open pulp, blood smear for Giemsa staining. The white blood cell count under a light microscope, the classification of the percentage. On the other hand, after the blood was collected as much as possible to the crown removed, fixed, embedded, sectioned, HE staining, tissue samples were microscopically examined. Pathological inflammation is divided into: no inflammation (-), mild localized inflammatory cell infiltration
