研究背景在超老龄化社会中，维持老年义齿佩戴者的生活质量是牙科医生最重要的任务之一。虽然外部机械负荷对可摘义齿已被调查，以尽量减少疼痛的风险所造成的义齿，感觉知觉的牙槽粘膜仍然objectivesThis研究旨在探讨影响的感觉功能的年龄和牙齿损失的牙槽粘膜的特点，深入了解在无牙个体的疼痛敏感性。以及18名年龄匹配的齿状参与者（EC）和18名年轻齿状参与者（YC）参与了这项研究。用von Frey丝（0.125~512 mN）测量触觉检测阈值（TDT）和痛阈值（PT）。使用0 - 50 - 100数字评定量表（NRS）（0：无疼痛，50：轻微疼痛，100：可想象的最严重疼痛）评估了在2秒内施加1 kg触诊后的机械疼痛敏感性（MPS）。结果在上下颌骨中，EC组TDT和PT均显著高于YC组，而艾德组TDT和PT均显著低于EC组。艾德组MPS的NRS显著高于EC组。所有的结果参数的熵分数显示groups.ConclusionTwo老化和牙齿脱落可以改变触觉和疼痛的感觉在口腔粘膜之间没有显着差异。提示在临床上对无牙颌患者进行义齿制作前的牙槽黏膜感觉功能评估可能是有益的。
BackgroundMaintaining quality of life of elderly denture wearers is one of the most crucial tasks for dentists in the super‐aged society. Although external mechanical load on removable dentures has been investigated to minimise a risk of soreness caused by dentures, sensory perception of the alveolar mucosa remains obscure.ObjectivesThis study aimed to investigate effect of ageing and tooth loss in sensory function on the alveolar mucosa for deep understanding of the characteristics of pain sensitivity in edentulous individuals.MethodsEighteen edentulous participants (ED), as well as 18 age‐matched dentate participants (EC) and 18 young dentate participants (YC), participated in this study. Tactile detection threshold (TDT) and pain threshold (PT) were measured with von Frey filaments (0.125–512 mN). Mechanical pain sensitivity (MPS) after a 2‐sec application of 1 kg palpation was assessed with a 0–50–100 Numerical Rating Scale (NRS) (0: no pain, 50: slight pain and 100: the worst pain imaginable). Furthermore, entropy scores of TDT, PT and NRS on MPS were calculated.ResultsIn both maxilla and mandible, EC showed significantly higher TDT and PT, compared with YC, whereas ED showed significantly lower TDT and PT, compared with EC. NRS on MPS in ED was significantly higher than that in EC. The entropy scores of all the outcome parameters showed no significant difference between groups.ConclusionBoth ageing and tooth loss can alter tactile and pain perception in the oral mucosa. This suggests that it might be beneficial to assess sensory function of the alveolar mucosa in edentulous patients clinically in prior to denture fabrication.
