Objective: Globally, baccalaureate programs in dental hygiene are increasingly established. In addition, in Japan, many dental hygienists (DHs) and social workers (SWs) are prematurely leaving the workforce. This study aimed to investigate the most recent employment, career outcomes, reasons for a job change, and satisfaction with the job and undergraduate curriculum among graduates of the baccalaureate program at the Department of Oral Health and Welfare (DOHW), Faculty of Dentistry, Niigata University. Methods: All 262 graduates (graduating classes 1–10) of the DOHW were invited to participate in this survey; an original self‐administered questionnaire was distributed to those who consented. Responses were received from 114 (43.5%) graduates. Results: Almost all respondents (89.5%) had dual licensure as both DH and certified SW. They were employed immediately after graduation (99.1%) and at the time of the survey (96.5%). Over 60% of them worked as DHs, mainly in hospitals. SWs mainly worked in administration. Among the 113 respondents who were employed, 39.8% changed jobs at least once. The main reasons for job selection were 'interest in job content' and 'flexible working hours'. Nearly 90% of the respondents felt satisfied or fairly satisfied with their job and their undergraduate education. Conclusions: A quality 4‐year baccalaureate degree program in dental hygiene and social welfare positively influenced graduates' work continuity. Most graduates felt satisfied or fairly satisfied with their job and the undergraduate curriculum. Employment rates within each profession and the prevalence of hospital and administrative roles were higher than national averages. Long‐term studies of graduates' career outcomes are warranted.

Background and Objectives: Several epidemiological studies have reported that smokers have a higher prevalence and severity of periodontal disease than do nonsmokers, and that smoking negatively affects nutritional status and is associated with a reduced intake of antioxidants, particularly vitamin C. The present investigation aimed to examine the relationship between serum vitamin C levels and smoking and its influence on the periodontal condition in older adults. Materials and Methods: A total of 353 respondents met the inclusion criteria and were enrolled in the present study. The periodontal status of the study participants was determined through examinations of one or more residual teeth, which included a measurement of the probing pocket depth (PPD) and clinical attachment level (CAL) at six regions of each tooth. Blood samples were collected during the dental examinations and then sent to a laboratory to evaluate serum vitamin C and cotinine levels. A serum cotinine concentration of 100 ng/ml was considered a relevant threshold for active smoking. After dividing the participants into two groups according to serum cotinine levels, Poisson regression analysis was carried out to compare vitamin C levels with the prevalence rate ratio (PRR) for periodontal condition markers for each group based on serum cotinine levels. Results: We evaluated differences in the PRR of serum vitamin C tertiles between participants with high (≥100 ng/ml) or low (<100 ng/ml) serum cotinine levels after adjusting for sex, the use of interdental brushes or dental floss, and the number of teeth. A negative tendency between the PRR of vitamin C tertiles for the PPD or CAL was seen for both groups. Especially, a bigger difference was observed in the group with high serum cotinine levels. The PRR of the first tertiles in the high serum cotinine group was 5.03, compared with 2.69 in the low serum cotinine group (relative risk: 1.9). Conclusion: The results of this study suggest a potential association between vitamin C levels and the periodontal condition, which may be influenced by smoking status. [ABSTRACT FROM AUTHOR]

Objectives: Root surface caries experience tends to increase with age. The purpose of this longitudinal study was to evaluate the relationship between aspects of dietary intake, including milk and sucrose in coffee or tea (SCT), and root surface caries in older Japanese individuals. Methods: 303 community‐dwelling older individuals (age 75 years) were enrolled for analysis. All participants underwent a dental examination at baseline and then annually from 2003 to 2008 (ie six times over a 5‐year period). A disease event was considered to have occurred when root surface caries was detected on a previously sound or nonexposed root surface. Over the observation period, disease events in each year were counted. Dietary habits during the preceding month were evaluated using a brief self‐administered diet history questionnaire (BDHQ) in 2003 and 2008. Poisson regression analysis performed crude and adjusted increment‐rate ratios (IRRs) for root surface caries and the intake of milk and SCT. Results: The adjusted increment‐rate ratio (IRR) of the increment of root surface caries for participants in the highest SCT tertile was 1.72 (95%CI: 1.40‐2.14) compared with the referent group. In addition, for the amount of milk intake, the adjusted IRR in the highest tertile was 0.63 (95% CI: 0.51‐0.78) compared with the referent group. Conclusions: Much SCT and low milk intake were associated with the increment of root surface caries in community‐dwelling older people in Japan. These findings suggest that to help prevent root surface caries, community‐dwelling older people in Japan should consume adequate amounts of milk daily and limit their intake of SCT.

Objectives: To examine the associations among alcohol consumption level, dietary intake and other lifestyle factors, and periodontal condition, in community-dwelling elderly Japanese of a specific age.Background: The relationship between alcohol consumption level and periodontitis is a controversial issue.Methods: Participants were 438 dentate elders aged 73 years from a larger cohort survey of elders in Niigata City, Japan. Data collected from oral examination of each participant, including number of the existing teeth, mean probing pocket depth and mean clinical attachment level (CAL) were used for the analyses. A semiquantitative food frequency questionnaire and a lifestyle habit questionnaire were used to assess food and alcohol consumption, smoking experience, frequency of tooth brushing, interdental brush use, and visits to a dental clinic during the previous year. Blood glucose control was assessed by the glycated haemoglobin (HbA1c) level. Body mass index was calculated from height and weight measurements. The relationships between each variable and the individual mean CAL were analysed by univariate and multivariate analyses.Results: According to logistic regression analysis, the mean CAL was significantly associated with the number of existing teeth (odds ratio [OR] = 0.90; P < .001), being a heavy drinker (OR = 2.44; P < .05), and smoking experience (OR = 2.37; P < .01).Conclusion: This study showed that increased mean CAL was significantly associated with heavy drinking in community-dwelling elderly Japanese (aged 73 years) compared with non-drinking. Our results provide new evidence that high alcohol consumption is associated with an increased risk of periodontal disease and its progression. [ABSTRACT FROM AUTHOR]

ABSTRACT Background and Objectives Methods Results Conclusions Weight loss is a critical health issue among the older population. This study aimed to explore the association between weight loss and oral health in older adults.We used cross‐sectional data from the Uonuma Chronic Kidney Disease Cohort Study. The binary logistic regression models were fitted to estimate the relationship between weight loss and independent variables including the number of teeth present.The participants included 1656 females and 1625 males. There were 1217 females (73.4%) and 1236 males (76.0%) with normal BMI (18.5 ≤ BMI < 25) in the previous year. Weight loss was determined over a 12‐month period. Individuals with normal BMI in previous year, and those with weight loss (≥ 5%) or those whom maintained a stable weight were further analysed. The regression analysis (model 3, fully adjusted) showed that females with 0 and 1–10 teeth present had a higher likelihood of losing weight (OR = 4.07; 95% CI = 1.85–8.93, OR = 2.33; 95% CI = 1.24–4.39) compared with those with 20 or more teeth. Current smokers had a higher likelihood of losing weight (OR = 3.15; 95% CI = 1.01–9.76) than lifelong abstainers. Among males, both current and previous smokers showed a higher likelihood of losing weight (OR = 4.94; 95%CI = 1.76–13.8, OR = 3.35; 95% CI = 1.29–8.68) than those who never smoked.This study indicates that the number of teeth and smoking are both linked to weight loss in females. However, in males, the association between the number of teeth and weight loss may be compromised due to the high prevalence of smoking in this group. [ABSTRACT FROM AUTHOR]
