龈沟内硫化物水平与牙周炎症关系的研究

目的观察龈沟内硫化物水平(sulfide levels,SUL)与牙周炎症之间的相关性,探讨SUL作为牙周监测指标的价值和可行性。方法通过临床检查和X线摄片,对牙周炎组17例,牙龈炎组15例及健康对照组15例,记录每颗牙齿6个位点的探诊深度、附着水平、松动度和探诊出血等临床指标,并用Perio2000 system金刚探针牙周诊断仪测定各位点的硫化物水平。结果3组研究对象的龈沟SUL差异有显著性(P<0.001),牙周炎组最高,牙龈炎组次之,对照组最低。SUL与上述几项牙周临床指标之间均呈正相关(P<0.001)。结论挥发性硫化物(VSC)可能在牙周炎症的病理过程中发挥重要作用。结合牙周临床指标,龈沟内SUL可作为反映牙周组织健康状况的监测指标。

Relationship between periodontal inflammation and sulfide levels in gingival sulcus

Objective To investigate the relationship between volatile sulphur compounds(VSC) and periodontal health status.Methods Seventeen patients with periodontitis,15 gingivitis patients and 15 periodontally healthy persons were included in the study.Clinical examinations including probing depth,attachment level,tooth mobility,bleeding on probing were performed at six sites of each tooth.Sulfur levels(SUL) were measured at the same six sites using a Diamond Probe/Perio 2000 system.Results The periodontitis group had a significantly higher SUL level than the gingivitis group did,and the gingivitis group had a significantly higher SUL level than the healthy group did(P<(0.001)).Significantly positive correlations were observed between the sulfide levels and other traditional periodontal parameters(P<0.001).Conclusion VSC may be associated with the initiation and progression of periodontal diseases.Combining with the traditional clinical assessments,SUL monitoring should be considered as a valuable periodontal parameter.
