Children's oral and dental health needs to be maintained from an early age in order to sustain the integrity of their teeth. A new dental health care monitoring named SIMOGI (Dental Health Monitoring System) application is proposed. This application is used by parents and it’s integrated with dental therapist’s account. The application has features of dental health care checklist and dental danger sign.  The aim of this study is to analyze changes in parental behavior towards the maintenance of children's oral health with the implementation of SIMOGI. This research is an experimental study with pretest and posttest design with control group design. The total sample used is 20 parents of elementary school in grade 3. A behavioral questionnaire on dental and oral health maintenance on knowledge, attitudes and actions were done to measure the effect changes. The category is grouped into bad, fair and good. This experiment ran for 21 days. The analytical test used is univariate analysis, bivariate analysis using the Wilcoxon test. The results show that in knowledge, there is no effect on control (p-value 1.000) and intervention group (p-value 0.785). There is effect on intervention group’s attitude (p-value 0.018) and no effect on control group (p-value 0.317). There is effect both in intervention (p-value 0.024) and control group (p-value 0.102). There is an effect of using the SIMOGI application on changes in parents' attitudes and actions in maintaining children's dental health. Knowledge of the parents is already in the good category.

Dental and oral health is the main need of people, including to children. Since, about 60 – 90% of children are suffering from dental caries. The prevention of dental caries is an important part of conducting. The digitalization era has influenced the dental and oral health education. Tooth brushing is one way to keep dental and oral health. However, the proper tooth brushing has not been achieved by children. Our objective is to conduct dental and oral health programs for children by creating a smart tooth brush named TOMON (Tooth Monster Hunter) and an application of monitoring named SIMOGI (Sistem Monitoring Kesehatan Gigi / Dental Health Monitoring System). We undertook this study by planning the monitoring system. The monitoring system is divided into three parties: dental therapist, parent and children. Dental therapists and parents are collaborated to handle and educate children about proper tooth brushing. Second, is the analysis of the requirement. The analysis stage consists of application program content. The last is the prototyping stage. In the prototyping stage, the smart toothbrush TOMON and application SIMOGI were made. The results of the research are the smart toothbrush TOMON and SIMOGI application can be used for health promotion for the children.
