An investigation into the cognitive flexibility of undergraduate dental hygiene students at two dental schools in Asia.

Background/purpose: Cognitive flexibility is a personality trait, which can influence how effectively a healthcare professional can manage a challenging clinical situation. This study explored the cognitive flexibility of undergraduate dental hygiene students at two universities in Asia to gather baseline information in order to consider whether there was an educational need for pre-clinical students with regards to this personality factor.

Materials And Methods: Participants were all undergraduate dental hygiene students in the 2022 academic year at Tokyo Medical and Dental University (TMDU; n = 79) and Taipei Medical University (TMU; n = 88).

Association between tooth loss and adherence to oral maintenance in a dental clinic: A retrospective study of more than 20 years.

Objectives: The relationship between adherence to professional oral maintenance visits and tooth loss is generally accepted in periodontal treatment; however, this relationship has not been clarified in general dental practices. We evaluated the effectiveness of adherence to professional maintenance by a retrospective survey in a private practice.

Methods: We retrospectively extracted data of 395 patients in a general dental practice who had been followed for more than 20 years.

Perceived stress and career planning awareness of Japanese and Taiwanese undergraduate dental hygiene students.

This study explored Japanese and Taiwanese dental hygiene students' perceptions of stress and their idea of career planning.

Materials And Methods: Participants were second- to fourth-year students in the 2020 academic year at Tokyo Medical and Dental University (TMDU; n = 60) and Taipei Medical University (TMU; n = 62).

Effects of two-year oral health information provision on changes in gingival crevicular fluid in male day-night shift workers.

Background/purpose: Although dental diseases are related to systemic diseases and daily habits and are known to affect the quality of life, little attention has been paid to the importance of oral hygiene in Japanese working-age adults. We, thus, aimed to assess changes in the periodontal condition of working-age adults after providing regular oral health information at their workplace for two years.

Materials And Methods: Two years of oral health information were provided to workers at four printing companies.

Dental Hygiene Learning Outcomes Obtained Through Computer-Assisted Simulation Modules.

Biochemical Gas Sensors (Biosniffers) Using Forward and Reverse Reactions of Secondary Alcohol Dehydrogenase for Breath Isopropanol and Acetone as Potential Volatile Biomarkers of Diabetes Mellitus.

This study describes two biosniffers to determine breath acetone and isopropanol (IPA) levels and applies them for breath measurement in healthy subjects and diabetic patients. Secondary alcohol dehydrogenase (S-ADH) can reduce acetone and oxidize nicotinamide adenine dinucleotide (NADH to NAD) in a weak acid environment. NADH can be excited by 340 nm excitation lights and subsequently emit 490 nm fluorescence.

An Inter- and Intraprofessional Education Program in Which Dental Hygiene Students Instruct Medical and Dental Students.

The aim of this study was to develop, implement, and evaluate an inter- and intraprofessional education program with a peer support joint practice in which dental hygiene students teach medical and dental students about oral health care for older people requiring long-term care. In 2015 at Tokyo Medical and Dental University, 22 dental hygiene students in their third year at the School of Oral Health Care Sciences (OH3), 110 students in their third year at the School of Medicine (M3), and 52 students in their third year at the School of Dentistry (D3) participated in this program. The OH3 students practiced with a whole-body-type simulator to learn oral health care for older people and then taught the methods to the M3 and D3 students according to their self-designed teaching plan.

[Relationship between oral health status and life behavior in junior and senior high school students in Japan].

A survey of dental diseases carried out by the Ministry of Health, Labour and Welfare in 2003 revealed that more than 40% of people aged between 5 and 25 suffer from periodontal diseases and the average number of DMFT has been decreasing. The lifestyle of junior and senior high school students in particular has changed drastically. This study investigated the relationship between dietary habits and oral diseases in junior and senior high school students in Tokyo.
