Background: Dental and oral health is one part that can not be separated from overall body health. Dental and oral care as a whole begins with dental and oral hygiene for each individual. Teaching methods of brushing teeth for children need to be given examples of a good model and with the simplest technique possible.Objectives: The research aims to increase the knowledge of SDN 33 Banda Aceh City students in maintaining dental and oral health and improve the dental and oral hygiene status of SDN 33 Banda Aceh City students.Method:  The research using a quantitative method with a descriptive approach, with the target of Class V students of SDN 33 Banda Aceh City Banda Aceh City totaling 30 children. Data analysis uses univariate analysis. The interventions provided were in the form of Dental Health Education (DHE).Results: The results of these community service activities show there is an increase in students' knowledge in the maintenance of dental and oral hygiene in SDN 33 Banda Aceh City students, with an increase before the intervention (pre-test) is in the sufficient category (56.7%) and after the intervention (post test) in the good category (96.7%). There was an increase in the status of dental and oral hygiene of students, with an increase before the intervention (pre-test) was in the bad category (100%) and after the intervention (post test) was in the good category (100%).Conclusion: It is recommended that schools provide regular counseling to students about the importance of maintaining oral health and holding joint toothbrushes to improve oral and dental hygiene.

The introduction of series capacitors in transmission lines causes problems in terms of reliability and the security of distance protection relays. As distance protection is widely used in the transmission network, the challenge of applying it to series compensated lines has been taken up by utilities and relay manufacturers in various ways. In the field of power system protection, developments are largely driven by relay manufacturers, and are often not published in the academic literature; the status and trend of the relay manufacturer’s development are better found in their product manuals and patent activity. Further insight into specific implementations by transmission utilities can be found from publications in industry-led forums and some academic journals. This article surveys the status and development of distance protection for series compensated lines, with a focus on industrial implementation and practical considerations. Factors that influence the protection of series compensated lines are presented. Implementation examples reported by utilities are summarized as examples of the different situations encountered and the methods used to deal with them. It is observed that many utilities use communication-aided protection in series compensated lines, and distance protection is used with reduced reach. Solutions described in relay manuals are presented to demonstrate the manufacturers’ approaches to problems associated with series capacitor protection. While there are methods to counter voltage inversion, current inversion seems to represent a more serious challenge. A patent overview indicates the trends in this domain to be moving towards time-domain-based faster protection methods.
