“…Nine studies investigated the association between oral conditions and sarcopenia, as well as oral conditions and sarcopenia diagnostic factors. Oral conditions were evaluated by number of teeth [11,30,33], occlusal support [ 9,12,15,26,32], and periodontal state [10].…”

“…Among the longitudinal studies, Hamalainen et al reported that periodontitis was related to a decrease in hand grip strength [10]. Hatta et al reported that a loss of posterior occlusal support was associated with reduced walking speed [26]. Tanaka et al found that the number of teeth influenced sarcopenia onset [33].…”

“…Some reports have shown relationships between oral health and hand grip strength [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24], walking speed [19][20][21][24][25][26], and skeletal muscle mass [13,19,22,24,27,28,29], which are measurements used in the diagnosis of sarcopenia. Despite the increasing number of reports that have appeared about the association between oral health and sarcopenia [27,[30][31][32][33][34][35], the details of this relationship remain poorly discussed.…”

Purpose: Sarcopenia has recently been attracting attention as an early sign of the need for nursing care in older adults. Some studies have reported that oral health is related to sarcopenia and its diagnostic factors (hand grip strength, walking speed, and skeletal muscle mass). However, the relationship between oral health and sarcopenia remains poorly investigated and no review to date has compiled the available research on this relationship. The aim of this review was to summarize the current evidence describing the association between oral health and sarcopenia. Study selection: The internet database PubMed was searched using various combinations of related and synonymous keywords for "oral" or "dental" or "oral health" or "oral function" and "sarcopenia" or "walking speed" or "hand grip strength" or "skeletal muscle mass." A total of 27 studies found to be eligible were critically evaluated and their key findings were summarized. Results: Most of the studies were cross-sectional and conducted in Japan. A wide range of oral factors, including number of teeth, occlusal support, periodontal state, occlusal force, mastication, tongue pressure, and swallowing, were covered. The overall findings were that oral health indices could be significantly associated with sarcopenia and its diagnostic factors. Conclusions: Relationships may exist between aspects of oral health and sarcopenia or its diagnostic factors. However, reports showing associations between oral health and sarcopenia are scarce, and definitive conclusions could not be drawn. Further longitudinal studies are necessary to confirm these relationships.

“…The influence of occlusal support on physical function has been demonstrated. Loss of occlusal support was associated with poorer mobility, increased risk of incident falls and decline in walking speed because loss of occlusal support affects body balance control . Moreover, a community‐based cohort study demonstrated that association between impaired dental occlusion and sarcopenia .…”

Occlusal support is associated with nutritional improvement and recovery of physical function in patients recovering from hip fracture

Objective This study aimed to elucidate the association between occlusal support and nutritional improvement and recovery of activities of daily living (ADLs) among elderly patients recovering from hip fracture. Background Many patients with hip fracture are malnourished, and malnutrition is associated with poor functional outcomes. Poor oral status is one reason for malnutrition because loss of occlusal support leads to masticatory disorders and can cause nutrient deficiencies. Methods We evaluated 202 elderly patients aged 65 years and older (mean age, 84.9 ± 7.9 years). We assessed nutritional status using the Mini Nutritional Assessment‐Short Form and ADLs using functional independence measure (FIM) scores. Occlusal support was recorded in accordance with the Eichner Index. We categorised participants into two groups according to the presence or absence of occlusal support, and statistical analyses were performed to investigate the differences between the groups. Results One group contained 152 participants (mean age, 85.5 ± 7.4 years) with occlusal support, and the other group contained 50 participants (mean age, 83.0 ± 8.9 years) without occlusal support. The group with occlusal support had greater gain of FIM and higher FIM efficiency than did the other group. Multivariate analyses showed that occlusal support was independently associated with nutritional improvement [odds ratio (OR) = 4.00, 95% confidence intervals (CI) = 1.90‐8.43] and motor FIM efficiency (R2 = .338, P < .001). Conclusions Our findings suggest that occlusal support is associated with nutritional improvement and the recovery of ADLs in patients recovering from hip fracture.

“…The present study involved a longitudinal analysis of data collected during baseline and follow‐up assessments for the “Septuagenarians, Octogenarians, Nonagenarians Investigation with Centenarians” (SONIC) study, a cohort study of health and longevity (Hatta et al., 2018, 2019). Participants were older adults living in private residences and were divided into a 70‐year group (aged 69–71 years at baseline in 2010–2011) and an 80‐year group (aged 79–81 years at baseline in 2011–2012).…”

Objectives Clinical evidence demonstrating the effectiveness of implants in preventing tooth loss is limited because of the many risk factors involved in tooth loss. This retrospective cohort study investigated whether an implant in the molar region of a distal free‐end edentulous space affects the loss of the most distal tooth after 6 years, adjusting for other risk factors associated with tooth loss using propensity score matching analysis. Material and Methods A total of 571 subjects and 1,085 teeth adjacent to a distal free‐end edentulous space were evaluated. At baseline, the 1,085 teeth were divided into two groups according to the presence or absence of a molar implant with a fixed dental prosthesis in the distal free‐end edentulous space. Propensity score matching analysis was used to reduce the effects of bias by matching teeth with and without implants according to similar background factors at baseline. The adjusted variables were age group, occlusal support status, Kennedy classification, tooth position, tooth type, restoration status, dental caries, periodontal pocket depth, and condition of the opposing tooth. Results A total of 56 teeth (28 associated with a molar implant; 28 with no implant) were enrolled according to propensity score matching. Fisher's exact test showed that a molar implant significantly protected the tooth adjacent to the distal free‐end edentulous space (p = .01). Conclusions Within the limitations of this retrospective cohort study, it was found that implants in free‐end edentulous spaces may be beneficial in extending the longevity of adjacent teeth. Further research will be necessary to confirm this finding.
