目的:在口腔肿瘤的治疗中,由于手术切除引起的广泛的颌骨缺损会降低咀嚼性能。在这里,我们旨在阐明颌骨缺损患者咀嚼能力的相关因素。
方法:总共,76例患者(男性42例,女性34例)在口腔肿瘤手术后接受了可摘义齿修复治疗,以治疗颌骨缺损。放射治疗史的资料,手术后的一段时间,当前义齿的使用期间,剩余牙齿的数量,并收集颌骨缺损部位。使用测试软糖果冻评价咀嚼性能。此外,最大咬合力,舌头的压力,舌唇运动功能(口服diadochokinesis/pa/,/ta/,/ka/),和口腔干燥进行评估。以较低的咀嚼性能评分为因变量进行Logistic回归分析。由于怀疑口腔diadchokinesis/ta/和/ka/音节之间存在多重共线性,进行了两个逻辑回归分析:以/ta/音节为解释变量的模型1,和模型2,其中/ka/音节作为解释变量。
结果:在模型1中,放射治疗史,最大咬合力,剩余牙齿的数量,舌头的压力,和口服diadochokinesis/ta/是重要的解释变量。在模型2中,放射治疗史,最大咬合力,剩余牙齿的数量,和舌头压力是重要的解释变量。
结论:有放疗史,最大咬合力,舌头的压力,剩余牙齿的数量,和孕激素的运动功能与颌骨缺损患者的咀嚼能力下降有关。
Purpose In the treatment of oral tumors, extensive jaw defects due to surgical resection can reduce masticatory performance. Herein, we aimed to clarify the factors related to masticatory performance in patients with jaw defects.Methods In total, 76 patients (42 male and 34 female) underwent prosthetic treatment with a removable denture for a jaw defect following oral tumor surgery. Data on history of radiation therapy, period of time since surgery, period of use of the present denture, number of remaining teeth, and site of the jaw defect were collected. Masticatory performance was evaluated using test gummy jelly. In addition, maximum bite force, tongue pressure, tongue-lip motor function (oral diadochokinesis /pa/, /ta/, /ka/), and oral dryness were evaluated. Logistic regression analysis was performed with lower masticatory performance scores as the dependent variable. Since multicollinearity was suspected between the oral diadochokinesis /ta/ and /ka/ syllables, two logistic regression analyses were conducted: Model 1 with the /ta/ syllable as an explanatory variable, and Model 2 with the /ka/ syllable as an explanatory variable.Results In Model 1, a history of radiation therapy, maximum bite force, number of remaining teeth, tongue pressure, and oral diadochokinesis /ta/ were significant explanatory variables. In Model 2, a history of radiation therapy, maximum bite force, number of remaining teeth, and tongue pressure were significant explanatory variables.Conclusions A history of radiation therapy, maximum bite force, tongue pressure, number of remaining teeth, and motor function of the proglossis are related to decreased masticatory performance in patients with jaw defects.
