Blood flow to the maxillary and mandibular gingivae was determined in 9 subjects under both normal conditions and in inflammation using the 133Xe clearance technique. A total of 36 sites (18 healthy and 18 inflamed) were selected for 133Xe injection. The clearance of radioactivity was monitored by a gamma camera. The calculated mean blood flows were 51.1 +/- 11.4 and 48.7 +/- 6.7 ml/100 g/min to the normal maxillary and mandibular gingivae, respectively. In inflamed gingiva, the corresponding mean blood flows were 55.0 +/- 13.0 and 54.7 +/- 11.7 ml/100 g/min, respectively. A statistical comparison of the healthy and diseased sites was done according to the paired t and Student's t tests. The difference between the sites was not significant (p > 0.05) in the maxilla, but significant (p < 0.05) in the mandible. There was no significant difference (p > 0.05) when the total healthy and diseased sites were compared.
采用¹³³Xe清除技术，在9名受试者的正常状态和炎症状态下，分别测定了上颌和下颌牙龈的血流量。总共选择了36个部位（18个健康部位和18个炎症部位）进行¹³³Xe注射。放射性清除情况由γ相机监测。计算得出，正常上颌和下颌牙龈的平均血流量分别为51.1±11.4和48.7±6.7毫升/100克/分钟。在炎症牙龈中，相应的平均血流量分别为55.0±13.0和54.7±11.7毫升/100克/分钟。根据配对t检验和学生t检验，对健康部位和患病部位进行了统计学比较。上颌部位的差异不显著（p>0.05），但下颌部位的差异显著（p<0.05）。当对所有健康部位和患病部位进行比较时，差异不显著（p>0.05）。
