■已经发现咀嚼口香糖可以改善口腔功能。然而,很少有随机对照试验研究咀嚼口香糖锻炼对老年人口腔功能的影响。这项研究旨在研究嚼口香糖运动对老年人口腔功能的影响。
■这是一个单盲,随机对照试验,从2021年11月到2022年1月进行。将130名参与者随机分为干预组和对照组。干预组被告知咀嚼实验牙龈一个月,而对照组被指示咀嚼实验片剂一个月。最大咬合力,咬合接触区域,口腔干燥,舌头的压力,舌头和嘴唇的功能(以下每个音节每秒发音的次数:/pa/,/ta/,和/ka/),咀嚼功能,主观咀嚼功能,在基线和干预后1个月测量口香糖咀嚼时间以评估结果.
■干预后一个月,干预组的舌压明显高于对照组(P=0.027)。在组内比较中,最大咬合力(P<0.001),未刺激的唾液流量(P<0.001),舌和唇功能(/pa/:P<0.001;/ta/:P<0.001;/ka/:P<0.001),色标值(P=0.019),干预组的ΔE值显著升高(P=0.024)。
■结果表明,嚼口香糖锻炼可以改善老年人的口腔功能,尽管在老年人中使用口香糖练习来建立更有效的口腔功能训练方法可能需要额外增加咀嚼负荷。
UNASSIGNED: Gum chewing has been found to improve oral function. Nevertheless, few randomized controlled trials have investigated the effects of gum-chewing exercises on oral function in older adults. This study aimed to examine the effect of gum-chewing exercises on oral function in older adults.
UNASSIGNED: This was a single-blind, randomized controlled trial, conducted from November 2021 to January 2022. A total of 130 participants were divided randomly into the intervention and control groups. The intervention group was told to chew experimental gums for one month, while the control group was instructed to chew experimental tablets for one month. Maximum bite force, occlusal contact areas, oral dryness, tongue pressure, tongue and lip functions (number of times each of the following syllables is pronounced per second:/pa/,/ta/, and/ka/), masticatory function, subjective masticatory function, and gum-chewing time were measured at baseline and one month following intervention to assess outcomes.
UNASSIGNED: One month following the intervention, tongue pressure was significantly higher in the intervention group than in the control group (P = 0.027). In the within-group comparisons, maximum bite force (P < 0.001), unstimulated saliva flow (P < 0.001), tongue and lip functions (/pa/: P < 0.001;/ta/: P < 0.001;/ka/: P < 0.001), color scale value (P = 0.019), and ΔE value (P = 0.024) were significantly increased in the intervention group.
UNASSIGNED: The results suggest that gum-chewing exercises can improve oral functions in older adults, although additional increases in masticatory load may be necessary to establish a more effective oral function training method using gum-chewing exercises in older adults.
