Introduction: Oral cancer remains a significant public health issue in Thailand, impacting the quality of life and contributing to increased Disability-Adjusted Life Years (DALYs). According to the Thailand National Cancer Institute (2021), the annual incidence of new oral cancer patients was more than 4,000 people. Key risk factors of oral cancer included tobacco and cigarette smoking, alcohol consumption, improper dentures, betel nut chewing, and viral infection.

Aims: This study aimed to evaluate the prevalence and distribution of oral cancer and potentially malignant disorders (PMDs) among older adults in each region in Thailand.

Methods: Online secondary data were retrieved from the Health Data Center Program of the Ministry of Public Health and the Cancer Registry reports of the Department of Medical Services, covering oral cancer screenings by dentists and dental hygienists conducted in public health settings across 77 provinces. The study population included individuals aged 60 years and older. The research analysis used descriptive and spatial geographical techniques.

Results: Oral screening data from government hospital reports found that 540 out of 1,614,549 older adults (0.03%) had signs of oral cancer and OPMDs. The highest prevalence of oral cancer is mainly in the age range of 60–65. The southern and central parts of Thailand had the highest incidence of oral cancer. In Bangkok, the ASR rate in males was more than in females, at 8:100,000; meanwhile, it was 4:100,000 in women. Whereas in the southern provinces, men have an ASR of approximately 5:100,000, which is higher than that of women at 2:100,000.
