This study aimed to compare the index of satisfaction and masticatory function of edentulous patients before and after rehabilitation and to evaluate if patients' perception of the changes in their oral health status is in agreement with the results of masticatory performance test. Fourteen edentulous patients were rehabilitated with lower implant-supported fixed prosthesis and upper removable dentures. Index of satisfaction and masticatory capacity (subjective analysis) and performance test (objective analysis) were evaluated before and 20 days and 8 months after rehabilitation. The patients were asked to respond a yes/no masticatory capacity questionnaire and to rate their oral satisfaction on a 0 to 10 Visual Analogue Scale (VAS). Masticatory performance test comprised the ability of the individual to pulverize an artificial test food (Optocal), after 20 and 40 masticatory strokes. When baseline answers were compared to answers 8 months after treatment, all questions, excepting the ones that considered pain and social disability, were statistically different. Wilcoxon test was used to compare index of satisfaction before and after treatment. All answers showed statistically significant differences, excluding the one that referred to ease of cleaning the prostheses. Considering the masticatory performance test, Student t test (normally distributed) and Wilcoxon test (non-normally distributed) were used to test the null hypothesis that the weight of the particles of the test food left in sieves were equal in all times of evaluation. In the larger sieve with 20 cycles, statistically significant differences were observed between baseline and 8 months, 20 days and 8 months. With 40 strokes, baseline and 20 days, baseline and 8 months and 20 days and 8 months showed significant differences. It was concluded that oral rehabilitation leads to better masticatory function in edentulous patients and there is a coincidence between patient perception and real improvement on masticatory function.
本研究旨在比较无牙颌患者修复前后的满意度指数和咀嚼功能，并评估患者对其口腔健康状况变化的认知是否与咀嚼性能测试结果一致。14名无牙颌患者接受了下颌种植支持固定义齿和上颌可摘局部义齿修复。在修复前、修复后20天和8个月时评估满意度指数和咀嚼能力（主观分析）以及性能测试（客观分析）。要求患者回答一份关于咀嚼能力的是/否问卷，并在0至10的视觉模拟量表（VAS）上对其口腔满意度进行评分。咀嚼性能测试包括个体在咀嚼20次和40次后粉碎人工测试食物（Optocal）的能力。当将基线答案与治疗8个月后的答案进行比较时，除了涉及疼痛和社会残疾的问题外，所有问题在统计学上均有差异。采用Wilcoxon检验比较治疗前后的满意度指数。所有答案均显示出统计学上的显著差异，但涉及清洁义齿难易程度的答案除外。考虑到咀嚼性能测试，使用学生t检验（正态分布）和Wilcoxon检验（非正态分布）来检验零假设，即测试食物留在筛子中的颗粒重量在所有评估时间均相等。在20个周期的较大筛子中，观察到基线与8个月、20天与8个月之间在统计学上有显著差异。在40次咀嚼时，基线与20天、基线与8个月以及20天与8个月之间均显示出显著差异。得出的结论是，口腔修复可使无牙颌患者的咀嚼功能得到改善，并且患者的认知与咀嚼功能的实际改善之间存在一致性。
