Effectiveness MyBRUSH Module in Improving Knowledge, Attitude, and Behaviour on Toothpaste Use and Toothbrushing Among 12-Year-Old Children

The goal of this intervention study is to study the effectiveness of the oral health education module (MyBRUSH) in improving the knowledge, attitude, and behaviour on toothpaste use and toothbrushing among 12-year-old children. This study also aims to study the effectiveness of the MyBRUSH module in improving dental plaque among 12-year-old children. The main questions it aims to answer are: 1. Does the knowledge, attitude, and behaviour on toothpaste use and toothbrushing of 12-year-old children improve after receiving the MyBRUSH module? 2. Does the dental plaque score of 12-year-old children improve after receiving the MyBRUSH module? 3. Does the improvement in knowledge, attitude, and behaviour regarding toothpaste use and toothbrushing, as well as the dental plaque of 12-year-old children, be higher after receiving the MyBRUSH module compared to those who received the existing toothbrushing module? Researchers will compare the MyBRUSH module to a BEGIN (existing toothbrushing module) to see if the MyBRUSH module is effective in improving the knowledge, attitude, and behaviour on toothpaste use and toothbrushing, as well as the dental plaque of 12-year-old children. Participants will: * A questionnaire will be used to assess knowledge, attitude, and behaviour regarding toothpaste use and toothbrushing. This assessment will be done at four time points (baseline, evaluation-1, evaluation-2, and evaluation-3), with a one-month interval between each time point. * A group of participants will receive intervention based on MyBRUSH module and another group of participants will receive intervention based on BEGIN. Each intervention activity will be done after each evaluation assessment is completed.
