Simplifying Oral health evaluation: a novel approach through single-item surveys.

Background: This study adopts a novel approach of using single-item surveys to simplify the assessment of oral health status and behaviors among Japanese private sector employees. We aimed to establish the validity of self-reported oral health in relation to clinical dental examinations, and to elucidate the relationship between oral diseases, health behaviors, and self-assessments. A secondary aim was to explore the association of self-rated oral health with oral health behaviors.

Determining the most appropriate socioeconomic status indicator for describing inequalities in dental visits by Japanese older people.

Objectives: This study examined the association between various socioeconomic status (SES) indicators and dental visits among older Japanese.

Although health check-ups are provided to workers in Japan, dental check-ups is not mandatory.

Association of Stressful Life Events With Oral Health Among Japanese Workers.

Background: Psychological stress can cause various mental and physical health problems.

We aimed to examine the association between a broader range of stressful life events and oral health among workers.

Association of overtime work duration with oral health-related quality of life in Japanese workers.

Purpose: Overtime work is associated with a risk of developing various diseases, including oral diseases. Oral Health-Related Quality of Life (OHRQoL) is a more comprehensive assessment than those of individual diseases and can be affected by longer working hours.

Methods: This cross-sectional study examined the association of overtime work duration with OHRQoL.

Urinary infection with a urachal remnant.

Urinary Gram staining is helpful in patients with complicated urinary retention, such as prolonged urinary retention and coexisting ureteral retention disease. If gram-positive rods are observed on urine Gram staining in a patient with urinary tract infection, an anaerobic culture of the urine may be helpful for early diagnosis and treatment of infection.

Association of visual display terminal time with prevalence of temporomandibular disorder among Japanese workers.

Objectives: Visual display terminal (VDT) time has been reported to affect the development of temporomandibular disorders (TMDs). However, no study has investigated the association between VDT time at and outside of work with TMDs Adjusting for known TMJ risk factors. This study aimed to investigate whether TMDs were associated with VDT time at and outside of work after adjusting for various working conditions in Japanese workers.

Concerning perceived and clinically-measured levels of halitosis.

The different types of self-reported halitosis complaints include those where one feels that one's breath smells bad, where one feels that one has bad breath because of the attitudes of others, and where others have pointed out the presence of bad breath. The results of previous studies comparing the objective and subjectives measures of halitosis are inconsistent, and few studies have used gas chromatography (GC) to measure halitosis in a large sample. This study aimed to examine the objectively measured halitosis levels based on the reasons individuals are concerned about halitosis.

Factors Affecting the Career Continuation of Newly Graduated and Reinstated Dental Hygienists Who Participated in a Technical Training Program in Japan.

This study aimed to identify (1) what newly graduated dental hygienists and reinstated dental hygienists consider important for preventing early turnover in their own professions and for encouraging them to continue in the profession more generally and (2) relevant factors among hygienists intending to continue working in the field. An anonymous, self-administered questionnaire survey was distributed to 215 Japanese dental hygienists who participated in the technical training programs (response rate: 72.6%).

Insulin overdose complicated by treatment-induced acute hepatic steatosis in a nondiabetic patient.

Background: There are few reports of dextrose-associated hepatic steatosis during insulin overdose treatment. Reports in nondiabetic patients are extremely rare. There is inadequate knowledge about the clinical course and treatment.

Association of marital status and access to dental care among the Japanese population: a cross-sectional study.

Background: Health disparities according to marital status have been reported worldwide. Although spouses provide an important social network that influences heath behaviors, limited studies have examined the association between marital status and access to dental care. Therefore, this study aimed to analyze the association between marital status and access to dental care.

Associations of the number of remaining natural teeth and oral health behaviors with subjective chewing problems based on the Thailand National Oral Health Survey 2017.

Purpose: Few studies have examined the association of oral health behaviors with chewing ability.This study aimed to investigate the associations between the number of remaining natural teeth and oral health behaviors with subjective chewing ability among older Thai adults.

Methods: Analysis was carried out using data from the 8th Thailand National Oral Health Survey.

Association between exposure to secondhand smoking at home and tooth loss in Japan: A cross-sectional analysis of data from the 2016 National Health and Nutrition Survey.

Introduction: Tooth loss affects oral health and physical and social functions. With widespread population aging, its prevalence is increasing. Secondhand smoking is a risk factor for oral diseases; however, in Japan, there are currently no regulations restricting exposure to secondhand smoke at home.

Periodontal health predicts self-rated general health: A time-lagged cohort study.

Objectives: There is limited evidence of a temporal relationship between periodontal diseases and self-perceived general health. To plug this knowledge gap, we aimed to assess how periodontal health affects future self-rated health (SRH).

Methods: We collected data from five waves of an annual nationwide Japanese survey of dental patients from 2015 to 2019.

Inequalities in Periodontal Disease According to Insurance Schemes in Thailand.

Few studies have considered the effects of insurance on periodontal disease. We aimed to investigate the association between insurance schemes and periodontal disease among adults, using Thailand's National Oral Health Survey (2017) data. A modified Community Periodontal Index was used to measure periodontal disease.

Multilevel Analysis of the Association of Dental-Hygienist-Related Factors on Regular Dental Check-Up Behavior.

Few studies have examined the factors related to dental clinics during dental check-ups. We examined the association between dental-hygienist-related factors and patients' regular dental check-ups. This nationwide cross-sectional study was based on a survey conducted in Japan in 2014.
