For complete denture wearers the tongue plays an important role in the retention and stability of dentures and has a great influence on masticatory function.
The purpose of this study was to elucidate the relationship between tongue motor behavior and masticatory function.
Thirty healthy, normal adult dentates, 10 normal elderly dentates, and 20 complete denture wearers whose dentures were constructed by the same methods and materials were selected. Tongue motor skills were examined by an ultrasound system and masticatory performance was evaluated by the sieving method.
The tongue motor skills of elderly dentates and complete denture wearers were statistically lower compared with those of adult dentates (p < 0.05, Duncan test). Tongue motor skills of complete denture wearers were statistically correlated with age (p < 0.01). Masticatory performance was statistically lower in relation to age in complete denture wearers (p < 0.01). The correlation coefficient was 0.74 between tongue motor skill and masticatory performance in complete denture wearers, which was statistically significant (p < 0.01).
Age-related decreases in tongue motor skills and masticatory performance were demonstrated by ultrasound observations and sieving methods.
对于全口义齿佩戴者而言，舌头在义齿的固位和稳定方面发挥着重要作用，并且对咀嚼功能有很大影响。
本研究的目的是阐明舌头运动行为与咀嚼功能之间的关系。
选取30名健康、正常的成年有牙者、10名正常老年有牙者以及20名使用相同方法和材料制作义齿的全口义齿佩戴者。通过超声系统检查舌头运动技能，并采用筛分法评估咀嚼性能。
与成年有牙者相比，老年有牙者和全口义齿佩戴者的舌头运动技能在统计学上较低（p < 0.05，邓肯检验）。全口义齿佩戴者的舌头运动技能与年龄在统计学上相关（p < 0.01）。全口义齿佩戴者的咀嚼性能在统计学上与年龄相关（p < 0.01）。全口义齿佩戴者的舌头运动技能与咀嚼性能之间的相关系数为0.74，具有统计学意义（p < 0.01）。
通过超声观察和筛分法证实了与年龄相关的舌头运动技能和咀嚼性能下降。
