What this trial studies
This cross-sectional study will recruit Thai adults aged 18–59 from the Mahidol University Dental Hospital. Participants will undergo anthropometric measurements (weight, height, BMI, waist circumference) and a detailed periodontal examination (PPD, CAL, BOP, GI, plaque score) to classify periodontal health. Information on demographics, medical conditions, smoking, alcohol use, sleep, and other health factors will be collected through an interviewer-administered questionnaire. BMI will be categorized using the Western Pacific Region criteria, and periodontal status will be classified per the 2017 AAP/EFP guidelines. The study aims to estimate the prevalence of high BMI and periodontitis and to identify associated factors in this population.
Why it matters
Potential benefit: If successful, findings could inform targeted prevention and awareness efforts linking oral and general health in Thai adults under 60.
How similar studies have gone: Other populations have shown associations between higher BMI and periodontitis; this study adds data from Thai adults under 60.
