The purpose of this study was to determine if functional changes in the human gingival vasculature were reversible following the resolution of gingival inflammation. Ten patients with 40 inflamed gingival sites were evaluated before and 2 weeks after the completion of treatment. We determined the hemoglobin concentration and the oxygen saturation of hemoglobin at each site by tissue reflectance spectrophotometry. With the use of treatment including motivation, oral hygiene instruction, and scaling, clinical parameters such as the gingival and plaque indices, the Periotron score, and the probing depth were altered toward a healthier state. With the resolution of gingival inflammation, the increased hemoglobin concentration and decreased oxygen saturation in the inflamed gingiva were restored to normal levels. These findings suggest that reversible changes in the local hemoglobin concentration and oxygen saturation are associated with decreasing gingival inflammation in human subjects.
本研究的目的是确定牙龈炎症消退后，人类牙龈血管系统的功能变化是否可逆。对10名患者的40个发炎牙龈部位在治疗前和治疗完成后2周进行了评估。我们通过组织反射分光光度法测定每个部位的血红蛋白浓度和血红蛋白氧饱和度。通过包括动机、口腔卫生指导和洁治在内的治疗，牙龈指数、菌斑指数、牙周探针评分和探诊深度等临床参数朝着更健康的状态改变。随着牙龈炎症的消退，发炎牙龈中升高的血红蛋白浓度和降低的氧饱和度恢复到正常水平。这些发现表明，局部血红蛋白浓度和氧饱和度的可逆变化与人类受试者牙龈炎症的减轻有关。
