Abstract Objectives The aim of this cross‐sectional study was to investigate the relationship of oral health status defined on the basis of presence of posterior occluding pairs ( POP s) and adequacy of removable denture fit as determined by self‐report to nutrient and food intake among older Japanese. Methods The subjects were 353 Japanese aged 80 years in 2008 and were classified into four groups according to the number of POP s, defined as pairs of occluding natural, restored, or fixed prosthetic postcanine teeth (range: 0–8) and removable denture status. The groups were: (i) good dentition ( n = 56; 8 POP s and no removable prosthesis), (ii) well‐fitting dentures ( n = 158; <8 POP s with self‐reported good‐fitting dentures), (iii) ill‐fitting dentures ( n = 70; <8 POP s with self‐reported ill‐fitting dentures), and (iv) compromised dentition ( n = 69; <8 POP s and no removable prosthesis). Multivariable analysis of the differences in nutrient and food intake outcome variables which were collected via validated food frequency questionnaire among the four oral health status groups was conducted using general linear models. Results Intake of multiple nutrients was significantly ( P < 0.05) lower in the group with ill‐fitting dentures or compromised dentition than in the good dentition group. Vegetable, fish, and shellfish consumption was significantly lower in the ill‐fitting dentures or compromised dentition groups. No significant differences were seen in dietary intake between the well‐fitting dentures and good dentition groups. Conclusions Dietary intake was poorer in those with self‐perceived ill‐fitting dentures or fewer POP s than among those having all POP s. Regular dental care to maintain intact dentition, as well as dental treatment to replace missing teeth and ensure adequate denture fit and function, may be important to the diet intake and subsequent nutritional status of older Japanese.
