Background: The high number of adolescent complaints related to dental and oral problems is related to the level of knowledge of adolescents in maintaining dental and oral health. Chewing xylitol gum is an alternative that has been proven to be quite effective in cleaning teeth from debris and plaque. Objective: This study aims to analyze the knowledge of students of junior high school PGRI 10 South Jakarta before and after being given education about chewing gum containing xylitol. Methods: This type of research is a quasi-experimental. The sample in this study amounted to 62 students, conducted in April 2022. Data collection by distributing pre-test and post-test questionnaires to measure knowledge before and after being given education about chewing gum containing xylitol. Data analysis using paired sample test. Results: Before the education was conducted, there were 9 students in the good knowledge category with a percentage of 14.5%, in the sufficient knowledge category there were 31 students with a 50.0% percentage, in the poor knowledge category there were 22 students with a 35.5% percentage. After education, there were 61 students in the good knowledge category with a percentage of 98.4%, in the sufficient knowledge category there was 1 student with a 1.6% percentage, in the poor knowledge category there were no students with a 0% percentage. The comparison of the average pre-test score is 6.05 while the total post-test average score is 9.40 with a p-value of 0.001.

This study aimed to determine the effect of scrapbook media on the knowledge and behavior criteria of students before and after the dental health learning process. This type of research is quantitative research with experimental methods used is quasi-experimental or quasi-experimental with the nonequivalent pretest-posttest control design groups. The population in this study were fourth-grade students at State Elementary School 05 Cilandak Timur, South Jakarta. The sample is a small part of the population that is taken according to certain procedures to represent the population. In this study, the researcher used a Stratified Random Sampling type random sampling technique which the researcher carried out to produce a sample of 4th-grade students in the morning and IV in the afternoon with state school status. The results were that the fourth-grade students from Public Elementary School 05 Cilandak Timur were the control class, while the fourth-grade students from Public Elementary School 03 were the treatment class. In this study, the instrument used was a test sheet in the form of multiple-choice questions to assess the knowledge criteria consisting of 25 multiple-choice questions regarding dental health. The grid of knowledge test instruments includes C4 (Analyzing) to C6 (Creating). Data collection techniques used are pre-test and post-test. The data analysis technique in this study used descriptive statistical analysis, prerequisite test analysis, and inferential statistical analysis.

This study aims to determine the effect of the classroom action learning model on dental health on the knowledge, attitudes, and behavior of upper-class students at Primary School 01 Cilandak Timur, South Jakarta. This study aims to increase students’ knowledge criteria by applying an action learning model for class V Elementary School in Cilandak State Elementary School. The subjects of this study were 32 class V students as the intervention class and class V Elementary School Borobudur as the control class. The method used was Classroom Action Research. This study used a pre and post-test design with a control group. The pre-test and post-test control group designs involve two classes: the experimental and control classes. Before being given treatment, both classes did a pre-test to get the initial cognitive abilities of the fifth graders. Then the two classes were offered the treatment to the experimental class, namely learning by applying good and correct brushing techniques, while the control class was not given any treatment. After learning, a post-test was conducted to determine the cognitive abilities of the experimental class and control class respondents. In this study, the sample used is part of the population, which is 10%. The sample calculation is 0,1 X 300, that is, 30 people in the intervention class and 30 in the control class with different schools. The results of the study can be concluded that the Classroom Action Learning Model in terms of the teacher’s ability to manage the class is said to be effective because the total percentage of good and very good assessments is more than the percentage of poor and quite good assessments, namely: 92% > 8%, Classroom Action Learning Model is reviewed of student activities in learning is said to be effective because the number of percentages of good and very good assessments is more than the number of percentages of poor and good enough assessments, namely: 75% > 25%, Class Action Learning Model in terms of student responses to learning is said to be effective because the number of assessment percentages good and very good more than the total percentage of assessments are not good and quite good, namely: 85% > 15%, Class Action Learning Model in terms of student learning outcomes after learning is said to be effective because the total percentage of assessments understands and understands more than the total percentage appraiser Ian understands well and quite understands, namely: 85% > 15%.

Tooth and mouth disease, a dental health problem in the community, is in the tooth-supporting tissue (periodontal disease) and dental/dental cavities. The causes of dental caries include food consumption, dental maintenance, and the teeth’ condition. In Indonesia, dental caries in children is a very important and major problem of dental and oral diseases. The survey conducted by the Indonesian Dental Health Foundation (YKGI) in 2003 on children in Jakarta showed that 70% suffered dental caries and gum inflammation. Tooth and mouth disease due to inflammation is ranked 10th in Indonesia. This study aims to determine the effect of knowledge and healthy behavior of upper (IV) elementary school students on good and correct tooth brushing skills and specifically to determine the level of knowledge and health behavior of children before and after being given good brushing and treatment skills right, to find out the difference in knowledge before and after being given the treatment of good and correct tooth brushing skills and to determine the differences in healthy behavior of children before and after being given the treatment of good and proper brushing skills.

Dental health is inextricably linked to overall wellness. One of the primary determinants of oral and dental health in poor nations is the behavioral component of dental hygiene, specifically brushing practice. The purpose of this study is to ascertain teeth brushing behavior and the factors that influence it in sixth-grade elementary school children in Lebak Bulus, South Jakarta. The study employed a cross-sectional design with a total sample size of 190 students. The data were gathered using an interview and a questionnaire. The findings indicated that up to 82.6 percent of sixth-grade kids engaged in inappropriate brushing behavior. Statistical analysis revealed a significant association between students' knowledge of the time and frequency of toothbrushing and their brushing behavior (p-value = 0.046). It is proposed that the Ministry of Health of the Republic of Indonesia adopt policies to support the development of dental health programs in school dental health services, particularly in the cognitive domain, attitudes, and behaviors of students who are concerned about their oral health.
