“…Three studies did not state whether subjects lived in assisted living facilities or in nursing homes, although in one study, some volunteers from one ward participated. Three of the studies had the same first author but were not duplicates. These three studies were the only ones that took place solely in rural communities.…”

A systematic review was conducted to assess the relationship between frailty or one of its components and poor oral health. A search strategy was developed to identify articles related to the research question in the PubMed, EMBASE, Cochrane, LILACS, and SciELO databases that were published in English, Spanish, or Brazilian Portuguese from 1991 to July 2013. Thirty-five studies were identified, and 12 met the inclusion criteria, seven of which were cross-sectional and five were cohort studies. Of the 12 articles, five (41.7%) were rated good and seven (58.3%) as fair quality. The published studies applied different oral health and frailty criteria measures. Variations in definitions of outcome measures and study designs limited the ability to draw strong conclusions about the relationship between frailty or prefrailty and poor oral health. None of the studies that were evaluated longitudinally showed whether poor oral health increases the likelihood of developing signs of frailty, although the studies suggest that there may be an association between frailty and oral health. More longitudinal studies are needed to better understand the relationship between frailty and oral health.

“…Lost pairs of occluding natural teeth and a decreased number of foods considered chewable were significantly associated with declined measures of lower extremity strength, agility and balance function parameters (4, 5). Self‐assessed masticatory ability was significantly and positively associated with handgrip strength, independent of skeletal muscle mass of the body (6). Decreased occlusal contacts in natural teeth can predict a future decline in certain physical performance parameters in older adults (19).…”

Increasing need for long-term care in older adults is expected with the ageing of Japan's population. The aim of the present study was to show the relationship between perceived chewing ability and long-term care needs for over 5 years in elderly persons. The chewing ability of 812 elderly persons living independently was evaluated at baseline using self-assessed masticatory ability, and it was classified into one of three categories: ability to chew all foods (good masticatory ability), ability to chew only slightly hard food (fair masticatory ability), and ability to only chew soft or pureed food (poor masticatory ability). Participants' care needs were then followed through Japan's long-term care insurance system for over 5 years. The log-rank test and Cox proportional hazard model were used to examine statistical differences in the frequency of care-needs certification between participants with good and fair or poor masticatory ability. Among participants aged 65-79 years, the frequency of care-needs certification was significantly higher in those with fair or poor masticatory ability than in those with good masticatory ability, and the relative hazard ratio was significantly higher in those with fair or poor masticatory ability than in those with good masticatory ability, after adjusting for age, gender, current employment status, educational background, social interaction, chronic medical conditions and dentition status. These relationships were not found among those aged 80-93 years. Impairment in perceived chewing ability may be associated with higher incidence of certification in Japan's long-term care insurance system among elderly persons aged 65-79.

“…Existing published evidence shows conflicting results on handgrip strength and various oral health conditions, such as periodontitis, the number of teeth, chewing ability, occlusal force, and tongue pressure . Two cross‐sectional studies failed to show a significant association between the number of teeth and handgrip strength in a Japanese population.…”
