The aim of this work was to evaluate saliva and tongue coating pH in oral healthy patients with morning bad breath before and after use of different oral mouthrinses.
Saliva and tongue coating pH of 50 patients allocated in 5 groups were measured respectively by a digital pHmeter and color pH indicators, before, immediately after and 30 min after rinsing 5 different mouthrinses: cetilpiridine chloride associated with sodium chloride, triclosan, enzymatic solution, essential oil and distilled water.
Only triclosan and essential oil increased salivary pH immediately after rising. The enzymatic solution decreased salivary and tongue coating pH immediately after rinsing.
Salivary pH tended to be acidic while tongue coating pH tended to be alkaline, even after rising. Triclosan and essential oil mouthrinses increased salivary pH immediately after rinsing. Enzymatic solution decreased saliva and tongue coating pH immediately after rising.
本研究旨在评估口腔健康患者在使用不同漱口液前后的晨起口气、唾液及舌苔 pH 值。
使用数字 pH 计和比色 pH 指示剂,对 50 名患者的唾液和舌苔 pH 值进行检测,将患者分为 5 组,分别在使用 5 种漱口液(西吡氯铵联合氯化钠、三氯生、酶制剂、精油、蒸馏水)前后即刻和 30 分钟后进行测量。
只有三氯生和精油能即刻增加唾液 pH 值。酶制剂能即刻降低唾液和舌苔 pH 值。
即使在升高后,唾液 pH 值仍倾向于酸性,而舌苔 pH 值倾向于碱性。三氯生和精油漱口液能即刻升高唾液 pH 值。酶制剂能即刻降低唾液和舌苔 pH 值。
