抽象目标。本研究的目的是评估通过粘度计测量的唾液粘度是否可以预测口腔异味。材料和方法。研究对象是 617 名曾到口腔异味诊所就诊的患者。感官测试（OT）用于诊断口腔恶臭。口腔检查评估现有牙齿和腐烂牙齿的数量以及是否有假牙。此外，还研究了牙周袋深度（PD）、牙龈出血、牙菌斑和舌苔。收集未刺激的唾液5分钟。用粘度计测量唾液粘度。以 OT 的口腔恶臭状态作为因变量进行逻辑回归分析。可能的混杂因素包括年龄、性别、存在的牙齿数量、蛀牙数量、PD≥4mm的牙齿数量、探诊出血的牙齿数量、是否有假牙、菌斑指数、舌苔面积、唾液流速、唾液pH值和唾液粘度被用作自变量。结果。唾液粘度（p = 0.047）以及PD≥4 mm的牙齿数量（p = 0.001）、菌斑指数（p = 0.037）和舌苔面积（p < 0.001）是口腔恶臭的重要变量。 PD ≥ 4 mm（OR = 1.32）、牙菌斑指数（OR = 2.13）、舌苔面积（OR = 3.17）和唾液粘度（OR = 1.10）的牙齿数量较多的受试者与数值较低的受试者相比，更有可能出现口腔恶臭。结论。结果表明，高唾液粘度可能是口腔异味的潜在危险因素。
Abstract Objectives. The objective of this study was to assess whether saliva viscosity, measured by a viscometer, was a predictor of oral malodor. Materials and methods. The subjects were 617 patients who visited an oral malodor clinic. The organoleptic test (OT) was used for diagnosis of oral malodor. An oral examination assessed the numbers of teeth present and decayed teeth as well as the presence or absence of dentures. Further, periodontal pocket depths (PD), gingival bleeding, dental plaque and tongue coating were investigated. Unstimulated saliva were collected for 5 min. Saliva viscosity was measured with a viscometer. Logistic regression analysis with oral malodor status by OT as a dependent variable was performed. Possible confounders including age, gender, number of teeth present, number of decayed teeth, number of teeth with PD ≥ 4 mm, number of teeth with bleeding on probing, presence or absence of dentures, plaque index, area of tongue coating, saliva flow rate, saliva pH and saliva viscosity were used as independent variables. Results. Saliva viscosity (p = 0.047) along with the number of teeth with PD ≥4 mm (p = 0.001), plaque index (p = 0.037) and area of tongue coating (p < 0.001) were significant variables for oral malodor. Subjects with a higher number of teeth with PD ≥ 4 mm (OR = 1.32), plaque index (OR = 2.13), area of tongue coating (OR = 3.17) and saliva viscosity (OR = 1.10) were more likely to have oral malodor compared to those with lower values. Conclusions. The results suggested that high saliva viscosity could be a potential risk factor for oral malodor.
