侵袭性牙周炎患者血清钙、磷分析

目的 分析侵袭性牙周炎患者是否存在血清钙、磷水平的异常。 方法 侵袭性牙周炎患者40例作为试验组，另选择牙周健康者40例对照组，空腹抽取静脉血，检测血清钙、磷水平，对两组血清结果进行比较，检查试验组附着丧失和牙齿松动度，与血清结果进行统计分析。 结果 试验组血清钙（1.9±0.5）mmol/L，明显低于对照组（2.3±0.4）mmol/L（P＜0.05），试验组血清钙低于正常值者24人，明显高于对照组17人（P＜0.05），Spearman相关分析显示血清磷与牙齿松动度存在相关性（P＜0.05）。 结论 侵袭性牙周炎组血清钙水平明显低于对照组，提示血清钙降低与侵袭性牙周炎之间可能存在相关性。

Study of serum calcium and phosphorus of patients with aggressive periodontitis

Objective To analyze whether there exists abnormal level of serum calcium and phosphorus in patients with aggressive periodontitis. Methods 40 patients with aggressive periodontitis were selected as the experimental group and another healthy 40 as the control group.Venous blood samples of patients were collected on an empty stomach.The levels of serum calcium and phosphorus of patients in two groups were detected and compared.Clinical attachment loss and tooth mobility were recorded and statistical analysis was done together with the serum results. Results The level of serum calcium which was (1.9±0.5)mmol/L in experimental group was higher than the control group ((2.3±0.4)mmol/L) (P＜0.05).The number of people with lower serum calcium in aggressive periodontitis group was 24 while there were 17 people in the control group.There was significant difference between two groups (P＜0.05).Spearman relativity analysis showed that serum phosphorus may be related to the tooth mobility. Conclusions Lower serum calcium may be related with aggressive periodontitis.
