Objective. The aim of this study was to assess the relationship between subjective oral health status and lifestyle in elderly people living in Japan. Methods. Subjects were 5383 inhabitants of the Kagawa Prefecture, Japan, at the age of 75-100. Records of the number of remaining teeth and the data from self-reported questionnaire were analyzed statistically. Results. Remaining teeth were significantly correlated to "no current smoking," while not related to other lifestyle. On the other hand, "subjective masticatory ability" defined as a condition allowing chewing all foods well was related to favorable lifestyles. "Subjective masticatory ability" was also related to "not feeling stress," "no deviated food habit" as well as to other good oral health conditions. A logistic regression analysis for "remaining teeth more than 20" revealed a significant relationship between "no current smoking" (OR = 1.582) and "no alcohol drinking" (OR = 0.851). Regarding "subjective masticatory ability," all favorable lifestyles analyzed in this study were found to be significant positive factors. Conclusions. "Subjective masticatory ability" seems to be strongly associated with favorable lifestyles. Therefore, it can be suggested that "subjective masticatory ability" might be a good landmark for quality of life of elderly people in addition to the number of remaining teeth.

Hardness is one of the dominant sensory characteristics of food. This study estimated the effect of sensitivity to hardness on the texture perception and chewing function using 2, 4, and 6% agar gels. Increasing the concentration of agar resulted in an increase in gel hardness and springiness, measured by texture profile analysis.

Geriatric oral health care encounters significant challenges with the increase in the proportion of older individuals. Age-related changes in the dentition, muscles, and joints result in a decline in objective masticatory function, subjective restoration requirements, and acceptability among the elderly population, with individual variations influenced by systemic health. Considering functional requirements, the adaptability of stomatognathic and systemic health conditions, health economics and other factors, the authors believe that it should not be limited to the conventional "one-to-one" strategy for replacing missing teeth in geriatric prosthodontics.

Objectives: This study evaluated the impact of masticatory difficulty on the development and progression of malnutrition, frailty, sarcopenia, and disability in community-dwelling adults, using data from the Korean Frailty and Aging Cohort Study.
Methods: Participants were categorised by presence of masticatory difficulty. The Fried frailty phenotype, mini-nutritional assessments, and diagnostic criteria proposed by Asian Working Group on Sarcopenia were adopted to diagnose frailty, malnutrition, and sarcopenia respectively.

Background/purpose: Previous studies have reported on changes in masticatory ability and patient satisfaction after restoration of missing second molars. However, there has been no evaluation of the masticatory ability and oral health-related quality of life (OHRQoL) of patients who did not replace their second molar. The purpose of the present study was to analyze the effects of the loss of a second molar on masticatory ability and OHRQoL.

Mini dental implants (MDIs) are alternatives to support an overdenture when a standard diameter implant cannot be placed due to lack of bone volume. They reduce the need for invasive bone grafting and lower the barrier for treatment. This prospective study reports on implant and patient-centered outcomes of flaplessly placed, early loaded MDIs supporting horseshoe-shaped maxillary overdentures after 7 years of function.
