Data are shown as medians (25^th–75^th percentiles) and as the means ± SD. Number of remaining teeth decreased among residents who consumed processed meals, except for liquefied meals. When comparing ordinary and processed meals, the difference in the number of remaining teeth was statistically significant. Numbers of tooth contact pairs in the premolar and molar regions were also statistically significant. However, for food consistency divided into ordinary, sliced, mashed and liquefied, differences were not significant *Mann-Whitney U test, ** Kruskal Wallis test
