title: [A study on evaluation methods of masticatory ability for complete denture wearers--correlation between evaluation using a questionnaire and masticatory performance].
abstract: The purpose of this study was to investigate the relation between evaluation by a questionnaire on masticatory aspects of 20 foods, and masticatory performance obtained using the sieving method, previously used in many studies. After replacement of upper and lower complete dentures made newly, 28 edentulous patients voluntarily participated in this study. The basal seat area of each patient was scored and divided into two groups, and masticatory ability was evaluated by two methods: using a questionnaire and the sieving method. The following conclusions were drawn from the data: 1. Evaluation of masticatory ability by both methods used in this study were not associated with gender, age, and evaluation of the basal seat area. 2. Evaluation using a questionnaire and masticatory performance showed significant correlation, and Spearman's correlation coefficient was 0.628 (p < 0.001).
