背景：口腔功能退化与多种因素有关，包括年龄增长、日常生活活动能力下降、营养不良和认知能力下降。这项横断面研究考察了年龄对健康个体口腔功能的影响。方法：对175名年龄在40-89岁、无痴呆且有20颗牙齿的健康、独立的日本牙科诊所就诊患者进行了回顾性研究。并与92名年龄在20~29岁的大学生进行比较。对日本老年医学会提出的口腔功能减退的7项诊断标准进行观察和统计分析。结果：与对照组比较，80岁以上组舌苔程度增加，70~79岁组咬合力降低，60~69岁及以上组舌运动功能降低，70~79岁组舌压力降低。结论：健康、独立的个体在衰老过程中保持多项口腔功能标准，包括口腔粘膜湿润度、咬合力、唇部运动功能、咀嚼功能和吞咽功能。舌运动功能和舌压随增龄而降低，提示这些可能是康复的靶点。
Background: Oral function deterioration is related to a variety of factors, including aging, decline in activities of daily living, malnutrition, and cognitive decline. This cross-sectional study examined the effects of aging on oral function in healthy individuals. Methods: A retrospective study was conducted on 175 healthy, independent patients aged 40-89 years, without dementia and with >= 20 teeth, who visited a local dental clinic in Japan. Patients were compared with 92 university students aged 20-29 years. The seven criteria proposed by the Japanese Society of Gerodontology to diagnose "oral hypofunction" were observed and statistically analyzed. Results: Compared with those in the control group, the degree of tongue coating was increased in the group aged over 80 years, occlusal force was decreased in the group aged 70-79 years, tongue motor function was decreased in the groups aged 60-69 years and older, and tongue pressure was decreased in the groups aged 70-79 years and older. Conclusions: Healthy, independent individuals maintained several oral function criteria across aging, including oral mucosal wetness, occlusal force, lip motor function, masticatory function, and swallowing function. Tongue motor function and tongue pressure decreased with aging, indicating that these may be rehabilitation targets.
