This study investigated decline in oral function in healthy young adults and compared it with that observed in an earlier studies employing older adults. The participants comprised 130 young healthy adults (mean age 24.1±2.9 yr), all with complete dentition. All participants underwent the oral hypofunction test established by the Japanese Society of Gerodontology, which evaluates oral hygiene, oral dryness, occlusal force, tongue-lip motor function (oral diadochokinetic rate; ODK), tongue pressure, and masticatory and swallowing function. The average value for and rate of hypofunction of each parameter were calculated. In healthy young adults, the scores were 28.9±17.1% for oral hygiene; 28.8±2.2 for oral dryness; 959.9±499.8 N for occlusal force; 7.0±0.8 times/sec for ODK /pa/, 7.6±0.8 times/sec for /ta/, and 6.9±0.9 times/sec for /ka/; 41.8±8.4 kPa for tongue pressure; 249.8±94.1 mg/dl for masticatory function; and 0.2±0.7 for swallowing function. No sign or symptom of change in oral function was observed at a high rate in young adults. Occlusal force, tongue-lip motor function, and tongue pressure showed a large difference in the rate of hypofunction between younger and older adults, however.
本研究调查了健康年轻成年人口腔功能的下降情况，并将其与早期采用老年人进行的研究进行了比较。参与者包括 130 名健康的年轻成年人（平均年龄 24.1±2.9 岁），所有人都有完整的牙齿。所有参与者都接受了日本老年牙科协会建立的口腔功能减退测试，该测试评估口腔卫生、口腔干燥、咬合力、舌唇运动功能（口腔交替运动率；ODK）、舌压以及咀嚼和吞咽功能。计算了每个参数的平均值和功能减退率。在健康的年轻成年人中，口腔卫生得分为 28.9±17.1%；口腔干燥得分为 28.8±2.2%；咬合力为 959.9±499.8 N；ODK/pa 为 7.0±0.8 次/秒，/ta/为 7.6±0.8 次/秒，/ka/为 6.9±0.9 次/秒；舌压为 41.8±8.4 kPa；咀嚼功能为 249.8±94.1 mg/dl；吞咽功能为 0.2±0.7。在年轻人中，口腔功能没有明显的变化迹象或症状。然而，咬合力、舌唇运动功能和舌压在年轻和老年成年人之间的功能减退率上存在较大差异。
