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、较为客观及可定量的检测方法 PURPOSE: To evaluate the relationship between visiting gingival bleeding (BOP) and visiting pressure. Methods: A total of 280 teeth from 10 healthy subjects were tested by self-developed pressure probe. Results: With the increase of visiting pressure, the mean BOP% increased significantly, and the BOP% was highly positively correlated with visiting pressure. Conclusion: The best clinical diagnosis of pressure in the control of 0.2N, exploration pressure over the General Assembly to increase the number of BOP false positives. At the same time, it shows that the pressure probe provides a simple, objective and quantifiable detection method for clinical research
