问题陈述。对于全口义齿佩戴者来说，舌在义齿的固位和稳定性中起着重要的作用，并且对咀嚼功能有很大的影响。本研究旨在阐明舌运动行为与咀嚼功能的关系。材料与方法。选择健康、正常成人牙30颗、正常老年牙10颗、全口义齿佩戴者20颗，采用相同的方法和材料制作义齿。采用超声诊断仪对患者的舌运动技能进行检测，并对患者的咀嚼功能进行筛选。老年义齿和全口义齿佩戴者的舌运动技能低于成年义齿患者(P<；0.05，Duncan检验)。全口义齿佩戴者的舌运动技能与年龄呈统计学相关(p<；0.01)。在全口义齿佩戴者中，咀嚼能力随着年龄的增长而降低(p<；0.01)。全口义齿佩戴者舌运动技能与咀嚼功能的相关系数为0.74，具有统计学意义(p<；0.01)。通过超声波观察和筛选方法，证实了与年龄相关的舌运动技能和咀嚼能力的下降。
Statement of Problem. 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.Purpose of Study. The purpose of this study was to elucidate the relationship between tongue motor behavior and masticatory function.Material and Methods. 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.Results. 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).Conclusion. Age-related decreases in tongue motor skills and masticatory performance were demonstrated by ultrasound observations and sieving methods.
