采用组织反射分光光度法（TRS）测定牙龈血红蛋白浓度（Hb指数）和氧饱和度（表观SO2）。牙龈的Hb指数明显低于牙槽粘膜，表观SO2明显高于牙槽粘膜，但不同牙龈区域的这两个参数均无差异。重复测量的重复性高，血红蛋白指数和表观SO2在牙龈。在发炎牙龈中，Hb指数显著高于临床健康牙龈。在发炎的牙龈中观察到较低的表观SO2。这表明血液供应的增加不足以满足发炎牙龈的氧气需求。Hb指数和表观SO2与牙龈炎症的临床指标如牙龈指数、菌斑指数、牙周膜评分和探诊深度之间存在显著相关性。因此，TRS可以在临床上用于估计发炎牙龈中的血容量和氧饱和度。
The hemoglobin concentration (Hb index) and oxygen saturation (apparent SO2) in human gingiva were estimated by tissue reflectance spectrophotometry (TRS). The gingiva had significantly lower Hb index and higher apparent SO2 than those in alveolar mucosa, but there was no difference in either parameter among different gingival areas. The reproducibility in repeated measurements was high for both Hb index and apparent SO2 in gingiva. In inflamed gingiva, Hb index was significantly higher than that in clinically healthy gingiva. A lower apparent SO2 was observed in inflamed gingiva. This suggests that the increase in blood supply is insufficient to meet the oxygen demand in inflamed gingiva. There were significant correlations between either the Hb index or the apparent SO2 and the clinical parameters of gingival inflammation such as gingival index, plaque index, Periotron score and probing depth. Thus, TRS may be clinically available to estimate the blood volume and oxygen saturation in inflamed gingiva.
