The ability to chew is not only an important dimension of oral health but is increasingly recognized as being associated with general health status. Whether perceived chewing ability and oral health-related quality of life OHRQoL are correlated to a similar degree in patient populations has been less investigated. The aim of this study was to examine whether perceived chewing ability was related to OHRQoL in partially dentate patients. Methods Consecutive partially dentate patients N 489 without signs or symptoms of acute oral disease at Tokyo Medical and Dental University s Prosthodontic Clinic participated in the study mean age 63.0 11.5 71.2 female . A 20-item chewing function questionnaire score range 0 to 20 was used to assess perceived chewing ability with higher scores indicating better chewing ability. The 14-item Oral Health Impact Profile-Japanese version OHIP-J14 score range 0 to 56 was used to measure OHRQoL with higher scores indicating poorer OHRQoL. A Pearson correlation coefficient was calculated to assess the correlation between the two questionnaire summary scores. A linear regression analysis was used to describe how perceived chewing ability scores were related to OHRQoL scores. Results The mean chewing function score was 12.1 4.8 units. The mean OHIP-J14 summary score was 13.0 9.1 units. Perceived chewing ability and OHRQoL were significantly correlated Pearson correlation coefficient -0.46 95 confidence interval CI -0.52 to -0.38 indicating that higher chewing ability was .
