(1) Background: The aim of this study is to review the benefits of the 8020 Campaign since its inception. (2) Methods: We followed the PRISMA guideline and collected information regarding the 8020 Campaign through online database searches. (3) Results: Twenty-five studies met the inclusion criteria and were eligible for analysis. The main outcomes of the 25 included studies were reviewed. The quality evaluation demonstrated a range of studies showing a credible relationship between masticatory function, number of teeth, salivary secretion, frequent dental check-ups, and general health concerns. Due to the risk of bias, publication bias, and indirectness, 22 studies were considered that only had “fair” quality. (4) Conclusions: The 8020 Foundation funded several of the studies, and other research papers noted the 8020 Campaign in their papers, however there were no clear explanations for any direct relationship between their findings and the 8020 Campaign. As a result, evidence for the direct effectiveness and benefits assessment of the 8020 Campaign positive outcomes were compromised by confounding social and economic variables over the 30-year period. To fully elucidate how improvement in Japan’s oral health was directly related to the 8020 Campaign, a more informed and systematic explanation of the campaign’s structure and activities is required.

Japan initiated a nationwide oral health promotion movement called the 8020 Campaign in 1989, which promoted oral health via a positive message: let’s keep at least 20 teeth when we reach the age of 80. This study aimed to understand Japan’s 8020 Campaign in terms of its content, actors, processes, and context. This study used qualitative data collection methods consisting of a literature review and Key Informant Interviews (KIIs). The data were analyzed using the health policy triangle framework. The results showed that the 8020 Campaign promoted oral health for individuals of all ages using a life-course approach and followed the Ottawa Charter framework for its core activities. The major facilitating factors suggested were stable financial support, initiatives led by local governments, the enactment of oral health laws and ordinances, the establishment of the 8020 Promotion Foundation, and increased attention focused on preventive approaches to oral health in Japan.

Objectives: This study examined the prevalence of tobacco and e-cigarette use, attitudes toward tobacco control, training on tobacco control in the dental curriculum, and attitudes toward e-cigarette use among Thai dental students. Materials and Methods: An online survey among 1968 Thai dental students was conducted in 2021. The questionnaire was modified from the Global Health Professions Student Survey with information collected on tobacco products, e-cigarette use, attitudes, and training toward tobacco control in the dental curriculum and personal information (e.g., sex, course year, regions, and types of dental schools). Descriptive analyses and χ² tests were performed. Results: The prevalence of tobacco and e-cigarette use among Thai dental students was 4.2%. Out of current users, 95% used e-cigarettes and 36.6% used multiple products, with a 1.7% prevalence of conventional cigarettes and other forms of tobacco use. Tobacco and e-cigarette use was higher in male than female dental students and was not associated with course year, region, and type of dental school. Conclusions: A small percentage of Thai dental students used tobacco or e-cigarettes, with the majority of current tobacco users being e-cigarette users. Thai dental students generally had a favorable view of tobacco control and a negative view of e-cigarette use. However, fewer than half of the surveyed students had received training in tobacco cessation therapy.
