Abstract
BACKGROUND It has been reported that the oral and gut microbiomes are associated with the prognosis in patients who undergo surgery, chemotherapy, and radiation for colorectal cancer. This study is the first to identify a correlation between the number of healthy teeth, which is an oral health indicator, and the efficacy of preoperative chemotherapy for rectal cancer. METHODS This retrospective single-center study included 30 patients who underwent radical surgery after preoperative chemoradiotherapy (CRT) between December 2013 and June 2021. The relationship between number of teeth before CRT and the efficacy of CRT, CRT-related adverse events, postoperative complications, and long-term postoperative outcomes was examined. RESULTS The number of healthy teeth was significantly greater in patients with downstaging of their disease than in those without downstaging (P = .027) and in patients with a complete response according to the Response Evaluation Criteria in Solid Tumors than in those who did not have a complete response (P = .014). Patients were divided into two groups according to whether they had ≥15 teeth or ≤14 teeth. There was no significant between-group difference in CRT-related adverse events. The incidence of all postoperative complications and grade II postoperative complications tended to be higher in patients with ≥15 teeth (P = .071 and P = .092, respectively), as did the 5-year overall survival rate (P = .083) and the 5-year disease-free rate (P = .007). DISCUSSION The number of healthy teeth predicted the response to preoperative CRT, postoperative complications, and the outcome of subsequent surgery in patients with rectal cancer.

Abstract
This cross-sectional study aimed to investigate the risk factors for low levels of subjective well-being (SWB) in the general population of Japan, specifically, the impact of the number of teeth and self-rated mastication. The surveyed population consisted of individuals aged between 40 and 79 years from Yamagata prefecture, Japan. A postal self-administered questionnaire survey of respondents lifestyles, medical history, oral health, and dietary intake, was conducted from 2017 to 2021. We included 6846 participants to confirm the independent associations between SWB and several parameters using multivariate ordinal logistic regression analysis to estimate adjusted odds ratios and 95% confidence intervals. Individuals with < 20 teeth and poor mastication ability had a 1.3-fold risk for low levels of SWB compared with individuals with ≥ 20 teeth with good mastication ability (adjusted odds ratios = 1.300, 95% confidence intervals = 1.043-1.621, P = .020). There were no differences between individuals with good mastication ability, regardless of the number of remaining teeth. Our study emphasizes not only the importance of having ≥ 20 teeth and good mastication ability for high levels of SWB but also the importance of restoring mastication ability using some form of prosthesis, to facilitate a high level of SWB when the number of remaining teeth is < 20.

Abstract
OBJECTIVES Although lower-extremity muscle strength is associated with physical function, there are challenges in assessing the muscle strength of patients after hip surgery due to pain or limited cognitive function. The number of teeth is a characteristic that can be easily examined. Although the relationship between the number of teeth and physical function has been reported in recent years, there are no reports examining the relationship with prognosis in patients with hip fractures. Therefore, this study aimed to investigate the relationship between the number of teeth and physical function and length of hospital stay after hip fracture surgery and to evaluate the predictive efficacy of the number of teeth on postoperative prognosis. METHODS This prospective cohort study was conducted in a tertiary clinical care facility. Patients aged ≥65 years who underwent hip surgery were included. A total of 101 patients (mean age: 85.1±8.0 years) were included. The factor analyzed was the number of teeth at admission. Patients were divided into two groups according to the number of teeth: those with ≥20 and those with ≤19 teeth. The outcomes were knee extension muscle strength-to-weight ratio at two weeks postoperatively and the length of hospital stay. A multiple regression analysis was performed to determine the association between the two groups. RESULTS Of 101 patients, 79 (78.2%) had ≤19 teeth, whereas 22 (21.8%) had ≥20 teeth. The mean muscle strength-to-weight ratio and length of hospital stay were 0.26±0.11 kgf/kg and 57.5±31.4 days, respectively. Multiple regression analysis revealed that the number of teeth was significantly associated with the muscle strength-to-weight ratio (β=-0.26, p=0.04) but not with the duration of hospitalization (β=0.17, p=0.09). CONCLUSIONS We suggest that assessment of the number of teeth at admission may be a useful predictor of patient physical function.

Abstract
OBJECTIVES To analyse the relationship between the Frailty Index and 10 oral conditions controlling for nutritional status among Mexican community-dwelling older people. BACKGROUND Studies suggest that the association between frailty and oral conditions are mediated by nutrition. MATERIALS AND METHODS This cross-sectional analysis includes 487 community-dwelling men and women aged ≥70 years old. Interview and clinical examinations were performed at participants' homes. Objective (number of natural teeth, root remnants, dental condition, utilisation and functionality of removable dental prostheses and periodontitis) and subjective (utilisation of dental services, self-rated oral health, chewing difficulties and xerostomia) oral variables were collected by trained personnel. The Frailty Index was calculated considering 35 deficits. Nutritional status measured with the Mini-Nutritional assessment (MNA), age, sex, education, and marital status were included as covariates. We fitted 11 multivariate generalised linear models (one for each oral condition), assuming gamma distribution for Frailty Index as the outcome. RESULTS Participants average age was 78.1 years, 52.1% were women. We observed a higher Frailty Index among those rating their oral health as worse than others their age (5.1%), reporting chewing difficulties often (4.9%) and fairly and very often (7.0%), and xerostomia (4.8%). Age, gender and MNA were consistently associated with the Frailty Index. CONCLUSION Subjective oral conditions are compatible with the Frailty Index after controlling for older people's nutritional status and covariates.

Abstract
Background and Objectives: Grip strength is a measure of general health and is associated with oral health. This study aimed to investigate the relationship between the number of teeth and grip strength in Korean adults. Methods and Materials: We recruited adult participants who underwent oral examinations in the Korean National Health and Nutrition Examination Survey (KNHANES) between 2016-2018. When performing the KNHANES oral examination, an experienced dentist performed it according to the oral examination guidelines and recorded the results. A total of 24,269 participants from the 2016-2018 KNHANES were included in this study. Of these, only 16,489 participants underwent oral screening. A total of 3209 were non-adult children and adolescents, and 1781 did not respond to the grip strength test; those who did not respond to the main independent confounder were excluded. The relationships between grip strength, general characteristics, general health, oral health, and the number of remaining teeth were analyzed. There were 11,499 subjects in total in this study, with 4839 males and 6660 females. The age groups were 19-65 years of age, with 8387 subjects, and 65 years and older, with 3112 subjects, and the number of remaining teeth was 0-9 for 936 subjects, 10-19 for 1015 subjects, and 20-28 for 9548 subjects. Results: The probability that the higher the grip strength, the higher the residual number of gingiva was estimated by multinomial logistic regression analysis using complex sampling. The higher the grip strength, the higher the probability of having 20-28 teeth remaining (adjusted odds ratio, 1.59; 95% confidence interval, 1.19-2.13). Conclusions: Maintaining general health is related to maintaining teeth; the higher the grip strength, the higher the number of remaining teeth.

Abstract
Intake of fiber, as well as protein, and lipid preloading help to control postprandial glycemic elevation in people with type 2 diabetes and in healthy individuals. However, there are few studies on the awareness of meal sequence and nutrient intake status that consider oral conditions. This cross-sectional study aimed to determine the effects of meal sequences on nutrient intake status and whether these relationships were related to the number of teeth present. The subjects were recruited from the Medical and Dental Collaboration Center of Kanagawa Dental University Hospital between 2018 and 2021. Medical and dental examinations were performed, and a questionnaire was used to determine whether the diet consisted of vegetables, meat or fish, and carbohydrates in that order. Nutrient intake status was assessed using the brief-type self-administered diet history questionnaire. Data were collected from 238 participants. The group with awareness of meal sequence ingested increased nutrients such as n-3 fatty acids, total dietary fiber, calcium, and vitamin C. Saturated fatty acid intake increased in those with fewer teeth, while it was not significantly related to meal sequence. In conclusion, our results showed that meal sequence was associated with nutrient intake status. In addition, the intake of saturated fatty acids increased when many teeth were lost, regardless of meal sequence.

Abstract
OBJECTIVES This study aimed to determine the association of periodontitis with cognitive impairment by evaluating periodontal conditions in middle-aged and elderly people of normal cognition and cognitive impairment. METHODS Forty patients with cognitive impairment and thirty-five healthy controls were included in this study. Mini-mental state examination (MMSE) was used to evaluate the level of cognitive function in all patients and controls. Periodontal conditions including severity of periodontitis, number of remaining teeth, percentage of bleeding on probing, probing depth (PD), and attachment level (AL) were examined. Periodontal conditions were compared between patients and controls, and the correlation between periodontal conditions and cognitive-function level was analyzed. Statistical analysis was performed with SPSS 26.0. RESULTS The distribution of severity of periodontitis significantly differed between patients and controls (χ2=13.309 and P=0.001). The proportion of severe periodontitis in the cognitive-impairment group was significantly higher than that in the healthy controls (P<0.05). The percentage of sites with PD≥6 mm and AL≥5 mm in the cognitive-impairment group was higher than that in the controls, whereas the percentage of sites with PD=1-3 mm and AL=0-2 mm was higher in the controls (P<0.05). No significant difference in percentage of bleeding on probing was found in the two groups (P>0.05). Patients with cognitive impairment had fewer teeth than the controls (P<0.05). The level of cognitive function, assessed by MMSE, was positively correlated with the number of teeth and the percentage of sites with AL=0-2 mm, and it was negatively correlated with the percentage of sites with AL≥5 mm (P<0.05). CONCLUSIONS A correlation existed between periodontitis and cognitive impairment. Further study is essential to explore the specific relationship and related mechanism between periodontitis and cognitive impairment.

Abstract
Teething is considered a significant event in the growth and development of the child by parents and especially by paediatric dentists and forensic scientists. They constantly need an “up-to-date mirror” of its variability for different geographic regions. The aims of the current study were to determine the timing and sequence of primary tooth emergence, and to establish a correlation between tooth eruption and general growth and external parameters in a sample of Romanian children. This study included 70 healthy children (53% girls and 47% boys), and the analysed data resulted from the questionnaires completed by parents during the whole process. General and specific data on primary teeth eruption were obtained. The differences between sexes were insignificant, except for the maxillary and mandibular canines (p = 0.047 and p = 0.018) and lower temporary second molars (p < 0.001), which were significantly increased in boys. The differences found between the two hemiarches were insignificant (p = 0.197). The mean age of eruption of the first tooth erupted was 7.07 ± 1.990 months. The unpaired t-test was used for comparison of the timings of eruption of the first primary teeth, according to the number of previous births and type of diet, and it was insignificant (p = 0.665 and p = 0.983 respectively).

Abstract
Aim The aim of this systematic review was to comprehensively and critically summarize and synthesize the risk of losing teeth among with diabetes mellitus (DM) compared to those without DM, as established in observational studies. Materials and methods MEDLINE‐PubMed and Cochrane databases were searched through a period from their inception through October 2020 to identify eligible studies. Papers that primarily evaluate the number of teeth in DM patients compared to non‐DM individuals were included. A descriptive analysis of the selected studies was conducted, and when feasible, a meta‐analysis was performed. The quality of the studies was assessed. Results A total of 1087 references were generated, and screening of the papers resulted in 10 eligible publications. A descriptive analysis demonstrated that six of these studies indicate a significantly higher risk of tooth loss in DM patients. This was confirmed by the meta‐analysis risk ratio of 1.63 95% CI (1.33; 2.00, p < 0.00001). Subgroup analysis illustrates that this is irrespective of the risk‐of‐bias assessment. The higher risk of tooth loss in DM patients was also higher when only DM type II patients or studies with a cross‐sectional design were considered. Patients with a poor DM control status presented a significantly increased risk of tooth loss. When the data were separated by the world continent where the study was performed, Asia and South America had numerically higher risks and a 95% CI that did not overlap with Europe and North America. Conclusion There is moderate certainty for a small but significantly higher risk of tooth loss in DM patients as compared to those without DM.

Abstract
Tooth loss reflects the endpoint of two major dental diseases: dental caries and periodontitis. These comprise 2% of the global burden of human diseases. A lower number of teeth has been associated with various systemic diseases, in particular, atherosclerotic cardiovascular diseases (ACVD). The aim was to summarize the evidence of tooth loss related to the risk for ACVD or death. Cohort studies with prospective follow-up data were retrieved from Medline-PubMed and EMBASE. Following the PRISMA guidelines, two reviewers independently selected articles, assessed the risk of bias, and extracted data on the number of teeth (tooth loss; exposure) and ACVD-related events and all-cause mortality (ACM) (outcome). A total of 75 articles were included of which 44 were qualified for meta-analysis. A lower number of teeth was related to a higher outcome risk; the pooled risk ratio (RR) for the cumulative incidence of ACVD ranged from 1.69 to 2.93, and for the cumulative incidence of ACM, the RR ranged from 1.76 to 2.27. The pooled multiple adjusted hazard ratio (HR) for the incidence density of ACVD ranged from 1.02 to 1.21, and for the incidence density of ACM, the HR ranged from 1.02 to 1.30. This systematic review and meta-analyses of survival data show that a lower number of teeth is a risk factor for both ACVD and death. Health care professionals should use this information to inform their patients and increase awareness on the importance of good dental health and increase efforts to prevent tooth loss.

Abstract
Background Although the feasibility of randomized trials for investigating the long-term association between oral health and cognitive decline is low, deriving causal inferences from observational data is challenging. We aimed to investigate the association between poor oral status and subjective cognitive complaints (SCC) using fixed-effects model to eliminate the confounding effect of unobserved time-invariant factors. Methods We used data from Japan Gerontological Evaluation Study (JAGES) which was conducted in 2010, 2013, and 2016. β regression coefficients and 95% confidence intervals [CIs] were calculated using fixed-effects models to determine the effect of deteriorating oral status on developing SCC. Onset of SCC was evaluated using the Kihon Checklist-Cognitive function score. Four oral status variables were used: awareness of swallowing difficulty, decline in masticatory function, dry mouth, and number of teeth. Results We included 13,594 participants (55.8% women) without SCC at baseline. The mean age was 72.4 (standard deviation [SD], 5.1) years for men and 72.4 (SD, 4.9) years for women. Within the 6-year follow-up, 26.6% of men and 24.9% of women developed SCC. The probability of developing SCC was significantly higher when participants acquired swallowing difficulty (β = 0.088; 95% CI, 0.065–0.111 for men and β = 0.077; 95% CI, 0.057–0.097 for women), decline in masticatory function (β = 0.039; 95% CI, 0.021–0.057 for men and β = 0.030; 95% CI, 0.013–0.046 for women), dry mouth (β = 0.026; 95% CI, 0.005–0.048 for men and β = 0.064; 95% CI, 0.045–0.083 for women), and tooth loss (β = 0.043; 95% CI, 0.001–0.085 for men and β = 0.058; 95% CI, 0.015–0.102 for women). Conclusion The findings suggest that good oral health needs to be maintained to prevent the development of SCC, which increases the risk for future dementia.

Abstract
Risk factors for tooth loss have been widely examined previously. However, no previous study has comprehensively investigated the risk factors, including lifestyle-related specific factors (parity, oral health habits, and socioeconomic status), for fewer than 20 teeth among women in the general population in Japan. This cross-sectional study explored the association of these risk factors, especially parity, with having fewer than 20 teeth among Japanese women. A self-reported questionnaire including items on lifestyle-related risk factors (parity, oral health, diet [e.g., alcohol and sucrose consumption]) and socioeconomic status was sent by post to female residents (age ≥ 40 years) of Takahata town, Yamagata Prefecture, in 2005. Multivariate logistic regression analysis including 3,854 eligible participants was performed to investigate the association between various factors (including parity) and having fewer than 20 teeth. The results indicated that, compared with nulliparous women, women with two, three, and four completed pregnancies had 2.485-, 2.844-, and 4.305-fold increased risk of having fewer than 20 teeth, respectively. Our study is the largest-scale study of the general female population in Japan and the first study to comprehensively investigate risk factors (parity, oral health status, and socioeconomic status) for fewer than 20 teeth. We thus found that higher parity, especially, two or more, was independent risk factors for having less than 20 teeth among Japanese women. In conclusion, the present study emphasizes the importance of good oral health habits in women, especially, during pregnancy and in the postpartum period, to maintain 20 or more teeth.

Abstract
OBJECTIVE Oral health status may be associated with dementia, which in turn results in higher medical costs among older people. METHODS This STUDY enrolled 4,275 older individuals. Generalized linear models were constructed with the medical costs of dementia as the dependent variable, and number of teeth, Community Periodontal Index (CPI), and other factors as independent variables. RESULTS Individuals with fewer teeth or with poor periodontal condition had significantly higher medical costs ratios for dementia independent of other confounding variables. The adjusted medical costs ratios of dementia were 4.13 (95% CI [confidence interval]; 1.79-9.56) for those with ≤9 teeth compared with those with ≥20 teeth and 3.48 (95% CI; 1.71-7.08) for those with personal CPI code 4 compared with those with personal CPI code 0-2. CONCLUSIONS Oral health status was associated with the medical costs of dementia. Preventing tooth loss and maintaining periodontal health may contribute to controlling dementia costs.

Abstract
OBJECTIVES The purpose of this study was to identify the age, period and cohort effects on the changes in oral health status in South Koreans. METHODS The age, period and cohort analysis (APC analysis) of the oral health status was conducted using an aggregated age-by-time period table. The age-by-time period table was formulated using data from the Korea National Oral Health Survey (KNOHS) 2000 and 2006, and the Korea National Health and Nutrition Examination Survey (KNHANES) 2010 and 2015. Two oral health outcomes were measured: the number of teeth and Decayed-Missing-Filled Teeth (DMFT) index. Descriptive analysis by graphical representation and partial least square (PLS) regression was used for APC analysis. RESULTS Both graphical description and PLS regression showed age and cohort effects in oral health status with the number of teeth decreasing and the DMFT index increasing with age. No period effects were found in either index. The number of teeth increased in the recent birth cohorts. However, the DMFT index showed a reverse J-shaped trend, which worsened in recent birth cohorts. The DMFT index increase in the recent cohort was mainly attributed by an increase in the FT index. CONCLUSIONS The effects of age on the number of teeth and caries highlight the importance of oral health in adulthood. The increased caries experience in recent cohorts may indicate the limitations of the current oral health policy. It would be relevant to explore what determinants cause the changes in oral health status. Future oral health policies should address the new directions to reduce the burden of oral diseases.

Abstract
Oral frailty is defined as a decrease in oral function accompanied by a decrease in mental and physical functions. Studies showing that people with oral frailty are at high risk of physical frailty, sarcopenia, severe conditions requiring nursing care and death have been reported in Japan. An increase in life expectancy and maintenance of teeth result in a decrease in the effect of the number of teeth. In contrast, a decrease in oral function as a result of aging has been suggested to have major effects on dysfunction and mortality risk. The present report is a narrative review of major clinical studies on the relationships of the number of teeth, dentures, occlusion and oral function with longevity, with the aim of providing information for future studies centered on oral function in Japan or overseas. This review clearly shows the relationships of the number of teeth, dentures, and occlusion with health and longevity. Recent studies have shown that, besides maintenance of the number of teeth, attempting to maintain or increase oral function, having a good diet and maintaining nutritional status are all linked to general health. Decreased oral function is a major risk factor for developing malnutrition and sarcopenia. Oral frailty, a new concept that has been recently introduced in Japan, is considered to have major effects on dental and oral health policies in Japan, in the old-age group, and is expected to be reflected in the dental and oral health policies of various countries, as they also predict increased life expectancies.

Abstract
The aim of this study is to determine the effect of food consistency on health and related factors among residents in welfare facilities for seniors (n = 227; mean age, 86.2 ± 8.0 years; 78.9% female). Residents who ate regular food had a lower incidence of fever during the 3-month period (p < 0.001) and consumed more calories (1325.97 ± 220.2 kcal) than those who ate chopped (1125.0 ± 256.8 kcal), paste (1122.0 ± 288.5 kcal), and gastric tube food (812.5 ± 150.7 kcal) (p < 0.001). Modifying a resident’s food by making it softer and finer did not reduce the incidence of choking. Logistic regression analysis (backward elimination method) revealed four factors related to eating regular food: vitality index, appetite, number of remaining teeth, and choking frequency. Causal relationships were not obtained because this was a cross-sectional study. The findings of this study suggest that a regular consistency of food positively influences the health of older individuals.

Abstract
OBJECTIVES To explore the association between the number of teeth and frailty among older Chinese adults using a nationally representative sample. DESIGN Cross-sectional analysis was carried out using the 2014 wave data from the Chinese Longitudinal Healthy Longevity Survey, which used a targeted random-sampling design. SETTING This research was conducted in communities from nearly half of the counties and cities in 22 out of 31 provinces throughout China. PARTICIPANTS Of the 6934 interviewees aged ≥65 years, the final analysis included 3635 older adults who had completed the 2014 wave survey on the variables included in the study. PRIMARY AND SECONDARY OUTCOME MEASURES Outcome variables included frailty, measured by the Frailty Index, and number of teeth. Covariates included demographic characteristics (ie, age, sex, co-residence, marital status, years of education and financial support), body mass index (BMI) and health behaviours (ie, smoking, drinking and exercise). A univariate logistic regression was used to test the factors associated with frailty. A multiple logistic regression model was used, using the frailty score as the dependent variable and the number of teeth together with significant covariates as the independent variables. RESULTS The prevalence of frailty was 27.68%. The mean number of teeth present was 9.23 (SD=10.03). The multiple logistic regression showed that older adults' demographic variables, health behaviours, BMI, tooth number and chewing pain were significantly associated with frailty. After adjusting for the covariates, older adults with fewer teeth had significantly higher odds of frailty than those with 20 or more teeth (no teeth: OR=2.07, 95% CI 1.53 to 2.80; 1 to 10 teeth: OR=1.77, 95% CI 1.31 to 2.38), except for older adults with 11 to 20 teeth (OR=1.30, 95% CI 0.93 to 1.82). CONCLUSIONS The presence of fewer teeth is significantly associated with frailty status among older Chinese adults. Future studies are needed to explain the specific mechanisms underlying how oral health status is associated with frailty.

Abstract
Purpose Oral frailty or the loss of oral functionality can be a symptomatic precursor of overall frailty. Previous studies have suggested that decreased tongue pressure causes a decline in ingesting and swallowing function and poor nutrition. This study investigated what factor(s) contribute to tongue pressure, thereby leading to frailty. Patients and methods For the purposes of the present study, 467 residents of Hirosaki city in northern Japan aged≥60 years who completed a questionnaire about frailty and underwent an intraoral assessment, which included number of teeth, presence or absence of periodontitis, tongue pressure, and oral diadochokinesis (ODK) were recruited. Results Of the 467 participants with complete data sets, frailty was identified in 13 (7.5%) of 173 males and in 34 (11.6%) of 294 females. Significantly fewer teeth, lower tongue pressure, and a reduced diadochokinetic syllable rate were more prevalent among frail than among healthy residents. Multivariable logistic regression analysis revealed that age, body mass index, number of teeth, and tongue pressure significantly contributed to frailty, whereas ODK did not. Multiple regression analysis showed that tongue pressure was positively associated with muscle index and number of teeth. Conclusion The results of the present study suggest that fewer teeth and lower tongue pressure, but not ODK function, are risk factors for developing overall frailty among older residents.

Abstract
The aim of this study was to examine the association between type of dental visit and number of remaining teeth in Japanese elders. Data were collected from 3,163 adults aged 75 or 80 years who underwent an oral health examination. Type of dental visit was classified into four categories by treatment(s) received (none, periodontal, caries, or other treatment). Number of remaining teeth was classified as ≥20, 10-19, or 0-9 teeth. Multivariate multinomial logistic regression analysis was used to examine associations between type of dental visit and number of remaining teeth among all participants and the 3,032 dentate elderly. As compared with elders who did not visit a dentist, those who received periodontal or caries treatments had a significantly lower odds ratio for having 0-9 teeth, and those who received periodontal treatment had a significantly lower odds ratio of having 10-19 teeth. In the multivariate linear regression model, number of days of periodontal treatment was positively associated with number of remaining teeth. Our results suggest that type of dental visit is associated with number of remaining teeth in Japanese elders.

A postal survey in the form of a self-administered questionnaire was distributed, and 6084 individuals were entered into the final statistical analysis. The self-administered questionnaire contained items regarding lifestyle, oral health status, socio-economic status and dietary intake. To examine the independent relationships between an underweight status and several parameters, a multivariate logistic regression analysis was used to estimate adjusted odds ratios (ORs). RESULTS The number of teeth, age, alcohol consumption, hypertension, spousal status, smoking habit, appetite, body weight at 20 years of age, habit of going out and physical activity were independently associated with an underweight status compared with the normal weight group. Individuals with fewer than 10 teeth were especially more likely to be underweight than individuals with more than 20 teeth (OR = 1.956, 95% CI = 1.261-3.035). CONCLUSION This study showed an independent association between the number of teeth and an underweight status, indicating that fewer teeth can increase the risk of being underweight.

Abstract
Given that public transportation networks are less developed in rural than in urban areas, a lack of accessibility to dental care facilities could be a barrier to routine dental checkups. Thus, we hypothesized that the distance to the dental care facilities is a risk factor for tooth loss. The aim of this study was to test whether there is an association between the distance to dental care facilities, estimated by geographic information systems, and number of teeth, assessed by an oral examination, among elderly residents of a rural area in Japan. Data were collected in 2016 from a cross-sectional study conducted in Shimane prefecture, Japan. After excluding participants with missing data (n = 21), we analyzed data from 710 participants. Of them, 40.6% were male and the mean (standard deviation) age was 67.4 (7.4) years. Further, 68.0% (n = 483) had at least 20 teeth. We found that the distance to dental care facilities was significantly associated with the number of teeth (less than 20) (odds ratio = 1.07, 95% confidence interval = 1.01–1.12) after adjustment for potential confounders. This result suggested that individuals without easy access to dental care facilities may be important targets for dental care.

Abstract
PURPOSE Prevention, early detection and effective rehabilitation of dysphagia are important issues to be considered in an aging society. Previous studies have shown conflicting findings regarding the association between dysphagia and its potential risk factors, including age, malnutrition, oral conditions, lifestyle and medical history. Herein, we assessed the prevalence and association of dysphagia with potential risk factors in 50- to 79-year-old adults dwelling in a community in Japan. PATIENTS AND METHODS In this study, there were 532 participants (185 males and 347 females). Participants who responded positively to the question "Do you sometimes choke on drinks/food such as tea and soup?" or those who presented with abnormal repetitive saliva swallowing test findings were diagnosed with dysphagia. The data collected from these participants included the following: number of teeth, occurrence of oral dryness, age, body mass index, serum albumin concentration, smoking, drinking and exercise habits, presence of diseases, such as diabetes mellitus and hypertension, and questions from the Mini-Mental State Examination. RESULTS Dysphagia was observed in 33 males (17.8%) and 76 females (21.9%). To explore the effect of the potential risk factors on the prevalence of dysphagia, a model was built by multivariate logistic regression analysis. Using the forced entry method, oral dryness (odds ratio [OR] =3.683 and P=0.003 in males; OR =1.797 and P=0.032 in females) and the number of teeth (OR =0.946 and P=0.038 in males) were found to be significantly related to dysphagia. CONCLUSION This cross-sectional study demonstrated associations between oral conditions and dysphagia. Factors such as oral dryness and number of teeth may contribute to dysphagia more so than aging, lifestyle and comorbidity in community-dwelling adults over the age of 50.

Abstract
Purpose Decline in the number of teeth and physical fitness begins from 40 years of age; however, several epidemiological studies have identified relationships between oral conditions and physical performance parameters in community-dwelling elderly population. The aim of this study was to validate the relationship between the muscle mass and its function and oral conditions (number of teeth and dental occlusion) after 40 years of age in a community-dwelling population in Japan. Materials and methods The subjects comprised of 552 volunteers (198 males and 354 females, 40–79 years) who participated in the Iwaki Health Promotion Project in 2013. Multiple linear regression analyses were performed with the measures of the muscle mass and its function as objective variables and the measures of the number of teeth, age, body mass index, medical history, serum albumin concentration, smoking status, habitual alcohol intake, marital status, education levels, and exercising habits as explanatory variables. The relationships between the Eichner index and the muscle mass and its function were analyzed using analysis of covariance, with adjustment for confounding factors. Results After adjusting for confounding factors, the number of teeth was shown to be an independent risk factor for the timed 10 m walk test (in females) and the skeletal muscle mass of the whole body (in males). The results also revealed that the timed 10 m walk test was significantly correlated with the Eichner index (Classes A and C in females were correlated). Conclusion This cross-sectional study on a Japanese community-dwelling population revealed relationships between oral conditions and the muscle mass and its function. However, the interpretation of our results was hampered by a lack of data, including those on socioeconomic status and longitudinal observations. Future research exploring teeth loss and the muscle mass and its function is warranted.

Abstract
OBJECTIVE To examine the association between occupational characteristics and number of natural teeth retained among older adults aged 50 and above. BACKGROUND Despite the integral part of the professional occupation of a person's time, few studies have examined the effect of the occupational environment on one's oral health. MATERIAL AND METHODS Self-administered questionnaires were randomly distributed among 280 participants, who had at least one professional occupation over a period of 10 years or more. Data from the questionnaire were collected concerning variables related to professional occupation and the self-reported number of natural teeth retained. The data were analysed using a logistic regression analysis with stepwise-backward selection. RESULTS Significant risk factors for the number of natural teeth being ≤25 were age (p < 0.001), years of education (p = 0.019) and a hospital/commercial environment of work (p = 0.021). The odds ratio for the number of natural teeth ≤25 increased with each year by 1.109, decreased with each additional year of education by 0.881, and was 2.693 folds higher for individuals working in a hospital/commercial environment compared to those in an office environment. CONCLUSIONS These findings suggest the importance of operating community-based oral health programmes for these occupational risk groups. The results from this study also implicate the need for further studies of this subject to find the underlying reasons for these occupational environmental risks.

Abstract
AIM To test whether the number of teeth, an inverse proxy for composite oral infection scores is associated with better survival. MATERIALS AND METHODS The Kuopio Oral Health and Heart study initiated a case-control study in 1995-1996 consisting of 256 consecutive coronary artery disease patients and 250 age and gender-matched controls. We appended the mortality data and formulated a longitudinal study. By May 31st, 2011, 124 mortalities had occurred and 80 of which were of cardiovascular origin. Using Cox proportional hazards models, we assessed the association of the teeth group (Teethgrp) - consisting of 10 teeth - with cardiovascular and all-cause mortality after 15.8 years of median follow-up. RESULTS In multivariate models, with the edentulous state as reference, one level increase in Teethgrp was associated with significantly increased survival from cardiovascular disease (CVD) mortality with a Hazard Ratio (HR) 0.73, p-value = 0.02 but not with all-cause mortality (HR = 0.87, p = 0.13). The findings were not mediated by C-reactive protein (CRP) levels ≥3 mg/L or by median fibrinogen levels, but were mediated by CRP levels >5 mg/L. CONCLUSION Each increment of 10 teeth from the edentulous state was associated with a 27% improved CVD survival, independent of low-grade systemic inflammation.
