摘　　要：目的：评价牙龈探诊出血（ＢＯＰ）与探诊压力之间的关系．方法：应用自行研制的压力探针对１０名牙龈健康的测试对象共２８０颗牙齿进行探测．结果：随着探诊压力的增大，ＢＯＰ％均值有明显增高趋势，ＢＯＰ％与探诊压力之间呈高度正相关．结论：临床上探诊压力最好控制在０．２Ｎ，探诊压力过大会使ＢＯＰ假阳性数增多．同时表明该压力探针为临床研究提供了一种简便的。Objective:To evaluate the relation between probing pressure and bleeding on probing.Method:We used the pressure-probe developed by ourselves to probe 280 teeth of 10 subjects with healthy periodontium.Result:The results showed that,with increasing probing pressure,the mean BOP% also increased evidently.Regression analysis revealed an almost linear correlation and a high correlation coefficient between BOP% and probing force. Conclusion Probing force should be controlled as 0.2N and uncontrolled forces may result in a proportion of false positive readings. It also demonstrated that the pressure-probe provide a simple,objective and quantitative probing method for clinical research.
