To clarify the relationship between masticatory performance and oral health-related quality of life (OHRQoL) before and after complete denture treatment.
Thirty patients wearing complete dentures were asked to chew a gummy jelly on their habitual chewing side, and the amount of glucose extraction during chewing was measured as the parameter of masticatory performance. Subjects were asked to answer the Oral Health Impact Profile (OHIP-J49) questionnaire, which consists of 49 questions related to oral problems. The total score of 49 question items along with individual domain scores within the seven domains (functional limitation, pain, psychological discomfort, physical disability, psychological disability, social disability and handicap) were calculated and used as the parameters of OHRQoL. These records were obtained before treatment and 3 months after treatment. Each parameter of masticatory performance and OHRQoL was compared before treatment and after treatment. The relationship between masticatory performance and OHRQoL was investigated, and a stepwise multiple linear regression analysis was performed.
Both masticatory performance and OHRQoL were significantly improved after treatment. Furthermore, masticatory performance was significantly correlated with some parameters of OHRQoL. The stepwise multiple linear regression analysis showed functional limitation and pain as important factors affecting masticatory performance before treatment and functional limitation as important factors affecting masticatory performance after treatment.
These results suggested that masticatory performance and OHRQoL are significantly improved after treatment and that there is a close relationship between the two. Moreover, functional limitation was found to be the most important factor affecting masticatory performance.
明确全口义齿治疗前后咀嚼性能与口腔健康相关生活质量（OHRQoL）之间的关系。
30 名佩戴全口义齿的患者被要求在其习惯咀嚼侧咀嚼一块胶状果冻，并测量咀嚼过程中的葡萄糖提取量作为咀嚼性能的参数。受试者被要求回答口腔健康影响简表（OHIP-J49）问卷，该问卷由 49 个与口腔问题相关的问题组成。49 个问题项目的总分以及七个领域（功能受限、疼痛、心理不适、身体残疾、心理残疾、社会障碍和障碍）内的各个领域得分被计算并用作 OHRQoL 的参数。这些记录在治疗前和治疗后 3 个月获得。比较治疗前后咀嚼性能和 OHRQoL 的各个参数。调查咀嚼性能与 OHRQoL 之间的关系，并进行逐步多元线性回归分析。
治疗后咀嚼性能和 OHRQoL 均显著改善。此外，咀嚼性能与 OHRQoL 的某些参数显著相关。逐步多元线性回归分析表明，治疗前咀嚼性能的重要影响因素为功能受限和疼痛，治疗后咀嚼性能的重要影响因素为功能受限。
这些结果表明，治疗后咀嚼性能和 OHRQoL 均显著改善，两者之间存在密切关系。此外，功能受限被认为是影响咀嚼性能的最重要因素。
