Oral care involving the removal of dry sputum is effective for older patients who require nursing care or hospitalization. However, safe and efficient oral care methods for such patients remain unclear. We aimed to simulate the oral cavity of older adults with dry mouth and elucidate the differences between two moisturization agents, water and gel-like oral moisturizer, and investigate the effect of occupation and experience on the amount of use and the ease of oral care. Using an oral care simulator (MANABOT, Nissin Dental Products Inc., Kyoto, Japan), 42 students and 48 dental professionals (13 dentists and 35 dental hygienists) performed oral care using moisturization agents to facilitate dry sputum removal. The time required for oral care, amount of water or gel used, amount of pharyngeal inflow, and ease of oral care when using water or gel were compared. The simulations revealed that the amount of use and pharyngeal inflow for gel (2.9 ± 1.6 and 0.3 ± 0.3, respectively) were significantly lower than those for water (6.8 ± 4.1 and 1.2 ± 1.5, respectively) in all participants. Using a gel-like moisturizer might reduce the aspiration risk in older patients requiring nursing care or hospitalization, regardless of occupation and experience.
口腔护理涉及清除干痰，对于需要护理或住院的老年患者有效。然而，对于这些患者，安全有效的口腔护理方法仍不清楚。我们旨在模拟口干的老年人口腔，并阐明两种保湿剂（水和凝胶状口腔保湿剂）之间的差异，并研究职业和经验对使用量和口腔护理便利性的影响。使用口腔护理模拟器（MANABOT，日本日清齿科产品株式会社），42 名学生和 48 名牙科专业人员（13 名牙医和 35 名牙科保健员）使用保湿剂进行口腔护理，以促进干痰清除。比较了口腔护理所需的时间、使用的水或凝胶量、咽入量以及使用水或凝胶时的口腔护理便利性。模拟结果表明，在所有参与者中，凝胶的使用量和咽入量（分别为 2.9 ± 1.6 和 0.3 ± 0.3）均明显低于水（分别为 6.8 ± 4.1 和 1.2 ± 1.5）。使用凝胶状保湿剂可能会降低需要护理或住院的老年患者的吸入风险，无论其职业和经验如何。
