A cross-sectional study of relationships between periodontal disease and general health: The Hitachi Oral Healthcare Survey. BMC Oral Health 2021; 21:644. [PMID: 34911523 PMCID: PMC8672581 DOI: 10.1186/s12903-021-01990-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Accepted: 11/22/2021] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND This cross-sectional study performed to clarify the relationship between periodontal disease and non-communicable diseases (NCDs), such as obesity, diabetes mellitus, impaired glucose tolerance (IGT), chronic obstructive pulmonary disease (COPD), and atherosclerotic cardiovascular disease (ASCVD) by introducing dental examinations into the annual health examinations conducted by Japanese companies, and to highlights the importance of a medical system that connects dental and medical professionals. METHODS A total of 1.022 Hitachi Ltd. employees were enrolled in this cross-sectional study. We examined correlations and odds ratios (ORs) between the dental and overall health of employees using stratification and multiple logistic regression analyses based on the periodontal health indicators, general health indicators, and occlusal force. RESULTS The adjusted OR of PPD for obesity (OR, 1.42; 95% confidence interval [CI], 1.09-1.84; p = 0.009), IGT (OR, 1.48; 95% CI, 1.00-2.20; p = 0.049), and COPD (OR, 1.38; 95% CI, 1.02-1.88; p = 0.038) significantly differed. The adjusted OR of body mass index (OR, 1.28; 95% CI 1.15-1.42; p < 0.001), haemoglobin A1C (HbA1c) (OR, 4.34; 95% CI, 1.89-9.98; p < 0.001), fasting blood glucose (FBG) levels (OR, 1.08; 95% CI 1.04-1.11; p < 0.001), postbronchodilator forced expiratory volume in one second/forced vital capacity ratio (%FEV1) (OR, 0.95; 95% CI 0.91-1.00; p = 0.031) and smoking (OR, 2.32; 95% CI 1.62-3.33; p < 0.001) for severe periodontal disease also significantly differed. Occlusal force was significantly reduced in employees aged 50-59 years compared to those aged 40-49 years. Both PPD, HbA1c, FBG levels were significantly associated with occlusal force among employees with moderate/severe periodontitis. PPD was significantly associated with occlusal force among employees with and moderate COPD, and ASCVD. %FEV1 was significantly associated with occlusal force among employees with IGT. CONCLUSIONS This cross-sectional study revealed mutual relationships among periodontal disease, NCDs, and occlusal force on Japanese corporate workers. We demonstrated that a comprehensive, regional healthcare system centred on annual integrated dental and physical health examinations in the workplace will benefit employees and positively impact corporate health insurance.

Fujimori K, Yoneda T, Tomofuji T, Ekuni D, Azuma T, Maruyama T, Sugiura Y, Morita M. Detection of Salivary miRNAs That Predict Chronic Periodontitis Progression: A Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18158010. [PMID: 34360304 PMCID: PMC8345340 DOI: 10.3390/ijerph18158010] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 07/15/2021] [Accepted: 07/27/2021] [Indexed: 12/12/2022]
Abstract
The aim of this two-year cohort study was to investigate salivary microRNAs (miRNAs) that predict periodontitis progression. A total of 120 patients who underwent supportive periodontal therapy were recruited. Unstimulated whole saliva was collected at baseline. Two years later, 44 patients were followed up (median age, 67.1 years) and divided into two groups: progression group (n = 22), with one or more sites with clinical attachment level (CAL) progression (>3 mm compared with baseline) or tooth extraction due to periodontitis progression; and the control group (n = 22), which did not exhibit CAL progression. In the microarray analysis of salivary miRNAs, hsa-miR-5571-5p, hsa-miR-17-3p, hsa-let-7f-5p, hsa-miR-4724-3p, hsa-miR-99a-5p, hsa-miR-200a-3p, hsa-miR-28-5p, hsa-miR-320d, and hsa-miR-31-5p showed fold change values <0.5 or ≥2.0 in the progression group compared with the control group (p < 0.05). On receiver operating characteristic curve analysis, areas under the curves of hsa-miR-5571-5p, hsa-let-7f-5p, hsa-miR-99a-5p, hsa-miR-28-5p, and hsa-miR-320d were >0.7, indicating fair discrimination power. The expressions of salivary hsa-miR-5571-5p, hsa-let-7f-5p, hsa-miR-99a-5p, hsa-miR-28-5p, and hsa-miR-320d were associated with periodontitis progression in patients with chronic periodontitis. These salivary miRNAs may be new biomarkers for progression of periodontitis, and monitoring them may contribute to new diagnostics and precision medicine for periodontitis.

Parafunctional masseter muscle activity during waking is related to periodontitis progression: A pilot prospective cohort study. J Clin Periodontol 2021; 48:785-794. [PMID: 33484572 DOI: 10.1111/jcpe.13432] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 01/03/2021] [Accepted: 01/15/2021] [Indexed: 12/16/2022]
Abstract
AIM The purpose of this pilot prospective cohort study was to investigate the effects of parafunctional masseter muscle activity on periodontitis progression among patients receiving supporting periodontal therapy (SPT). MATERIALS AND METHODS We collected data of patients treated at Okayama University Hospital from August 2014 to September 2018. The progression group was defined as patients with ≥2 teeth demonstrating a longitudinal loss of proximal attachment of ≥3 mm during the 3-year study period and/or at least one tooth extraction due to periodontitis progression. Surface electromyography of masseter muscles at baseline was continuously recorded while patients were awake and asleep. RESULTS We analysed 48 patients (36 females) aged 66.8 ± 9.1 years (mean ± SD). The rate of parafunctional masseter muscle activity during waking hours and sleeping hours at baseline was 60.4% and 52.1%, respectively. Cox's proportional hazards regression model showed that the incidence of periodontitis progression was significantly associated with number of teeth present (p = 0.001) and parafunctional masseter muscle activity during waking hours (p = 0.041). CONCLUSION Our results suggest that parafunctional masseter muscle activity during waking hours is a risk factor for periodontitis progression among patients receiving SPT.

Validity of a New Kit Measuring Salivary Lactate Dehydrogenase Level for Screening Gingivitis. DISEASE MARKERS 2017; 2017:9547956. [PMID: 28337048 PMCID: PMC5346391 DOI: 10.1155/2017/9547956] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/14/2016] [Revised: 02/03/2017] [Accepted: 02/07/2017] [Indexed: 01/27/2023]
Abstract
Aim. The aim of this study was to determine the usefulness of a new kit that can evaluate salivary lactate dehydrogenase (LD) level in real time for screening gingivitis. Materials and Methods. The study included 70 systemic healthy volunteers [29 males and 41 females; mean age ± SD: 24.1 ± 2.6 years]. Resting saliva was collected from each participant and LD level was evaluated in real time using the kit (a color-changing sheet with an integer scale ranging from 1 to 10). A dentist measured probing pocket depth, clinical attachment level, and the proportion of sites with bleeding on probing (% BOP) at six sites on all teeth. Gingivitis was diagnosed when the BOP value was ≥20%. Results. Salivary LD level was positively correlated with mean % BOP (odds ratio: 1.47, 95% confidence interval: 1.132–1.916, and P < 0.001) in a logistic regression model. The sensitivity and specificity of the kit were 0.89 and 0.98, respectively, at a cut-off value of 8.0 for LD level. Conclusions. The new kit for measurement of salivary LD level may be a useful tool to screen for gingivitis in young adults, which contributes to early detection of future periodontitis.

Abstract
OBJECTIVE Little information is available on how impaired masticatory performance relates to heart-rate variability (HRV). The aim of this study was to investigate the relationship between HRV indices and masticatory performance. MATERIALS AND METHODS Sixty-five subjects (19 men and 46 women, 66.1 ± 9.9 years old) who had received periodontal maintenance care at the Clinic of Preventive Dentistry of Okayama University Hospital were selected for the study. All subjects completed written questionnaires, a chewing (colour-changing gum) test for masticatory performance and measurement of occlusal force and HRV as well as oral examination. RESULTS The high sympathetic activity (LF ≥ 49.6) group showed a significantly lower level of masticatory performance (a* value) than the low sympathetic activity group (p < 0.05). There were also significant correlations of masticatory performance with LF and LF/HF (p < 0.05). CONCLUSION These findings suggest that there is relationship between masticatory performance and HRV indices and impaired masticatory performance may be a risk factor for inducing high sympathetic activity.

Abstract
AIM Periodontitis induces overproduction of reactive oxygen species (ROS). This state increases circulating ROS levels and may affect hepatocellular carcinoma (HCC). The Japan Integrated Stage (JIS) score is a novel staging system for HCC. The objective of the present study was to compare JIS scores in HCC patients with and without periodontitis. MATERIAL AND METHODS We recruited 64 HCC patients comprising 31 chronic periodontitis subjects (HCC + P) and 33 periodontally healthy controls (HCC + H). Their JIS scores were recorded. Serum levels of reactive oxygen metabolites (ROM) from HCC + P, HCC + H and healthy age- and gender-matched subjects with healthy gingiva (control, n = 15) were also assessed for circulating ROS levels. RESULTS The HCC + P and HCC + H groups had similar body mass index, habitual drinking and tobacco exposure data. The HCC + P group showed higher JIS scores than the HCC + H group (p = 0.027). Both the HCC + P and HCC + H groups had higher serum levels of ROM than controls (p < 0.001), while serum levels of ROM in the HCC + P group were a further 25.8% higher than those in the HCC + H group (p < 0.001). CONCLUSION HCC patients with periodontitis had higher JIS score and circulating ROS level than HCC patients without periodontitis.
