Prevalence and Associated Factors of High BMI and Periodontitis in Thai Adults Aged Under 60 Years

Overweight and obesity, as well as periodontitis, are common public health problems with increasing prevalence. Both conditions may be linked through shared mechanisms involving chronic low-grade systemic inflammation. Numerous studies have reported an association between elevated body mass index (BMI) and periodontitis, particularly among younger and working-age populations. However, data regarding Thai adults under the age of 60 remain limited. Therefore, this study aims to determine the prevalence of high BMI and periodontitis among Thai adults aged 18-59 years and to identify factors associated with these conditions. The findings may provide useful information for improving awareness and supporting the prevention of both periodontal and general health problems in this population.

Evaluating Methods of Dental Health Instructions on the Oral Health Indices of 12-18-year-old Patients With Fixed Orthodontics

The goal of this clinical trial is to learn which type of oral health education works best to help 12-18-year-old participants with fixed orthodontic appliances (braces) keep their mouths healthy. The main questions it aims to answer are: Which method of oral hygiene instruction-video-based, written, or face-to-face education-is most effective in improving oral health? Do these education methods help lower dental plaque and gum inflammation during orthodontic treatment? Researchers will compare the three groups of participants who receive different types of oral hygiene training to see which method leads to the best oral health results. Participants will: Receive one of three types of oral hygiene instruction (video, written, or in-person). Continue their regular orthodontic care and brushing routine. Have their oral health checked at different times during the study to measure changes in plaque and gum health. The study hopes to identify the most effective and practical way to teach young orthodontic patients to keep their teeth and gums healthy while wearing braces.
