Purpose: To identify the intrinsic factors affecting masticatory functions, parameters associated with clinical oral findings together with bite force and questionnaires were investigated. Methods: Cross-sectional data were derived from clinical examinations, periodontal pocket probes, bite force recordings, masticatory satisfaction scores and eatable food scores. Two hundred and thirty-five subjects in their 40's and 50's (94 males and 141 females; mean age of 49.3±5.5 years old) who were under care of dental clinics were administered in this survey. Results: The results showed that eatable food score was 92.4±12.4 (Mean±SD), masticatory satisfaction score 7.0±2.7, number of residual teeth 24.5±3.9, number of occlusal supporting zone 3.3±1.0, bite force 1, 376.4±830.1 N, and occlusal contact area 39.2±29.4 mm2. Multiple regression analysis showed that eatable food score was associated with the number of residual teeth and the bite force, while masticatory satisfaction score was associated with periodontal pocket depth in the posterior region in addition to the number of residual teeth, and with occlusal supporting zone. Conclusions: From the results of this study, the number of residual teeth and bite force are related to the function of eating foods, while periodontal status can play an important role in the satisfaction of eating.
