Abstract

Background: Oral and dental health problems remain a significant issue in Indonesia, especially among adolescents. The low level of knowledge regarding oral hygiene practices is one of the main causes of the high prevalence of dental caries in individuals aged 15–18 years. Therefore, engaging and effective educational methods are needed to raise awareness and improve adolescents’ knowledge of oral health maintenance. Objective: This study aimed to effective the level of knowledge among adolescents before and after a health education intervention using the ClassDojo application. Method: This research employed a quasi-experimental design with a one-group pretest-posttest approach. The sample consisted of 33 adolescents selected through total sampling. Data were collected using pretest and posttest questionnaires distributed online via the ClassDojo application. Results: The study showed an increase in knowledge, from 48.5% in the moderate category before the intervention to 93.9% in the good category after the intervention. Conclusion: Health education using the ClassDojo application is effective in improving adolescents’ knowledge of oral and dental health maintenance.

Abstract

Background: Strawberries (Fragaria x ananassa) are a fruit plant in the form of herbs that were first discovered in Chile, America. The benefits of strawberries are used as a natural ingredient to overcome all dental and oral problems. Tooth stains are pigmented layers on the surface of the teeth, one of the aesthetic problems, usually occurring due to the adhesion of food, drink, or cigarette color that leaves a brown to black layer on the teeth, which occurs over a long period of time is difficult to remove by brushing. Objective: The purpose of this study was to determine the effectiveness of strawberries in cleaning extrinsic stains and saliva pH in the academic community of the Polytechnic Health of Jakarta I. Method: Quasi-experimental research design with a pre-post experiment approach. The sample used was 60 people. Changes in extrinsic stains were measured using the Lobene Stain Index, which measures the intensity and extent of the stain, as well as a combined score of both, then measuring the pH of saliva using litmus paper. Results: The average combined score was 5.03. The extrinsic stain score after strawberry application showed an average combined score of 2.23. After analysis using the Dependent T test (paired test) and a p-value of 0.01. Meanwhile, the results of the saliva pH analysis obtained a p-value of 0.01 (P<0.05). Conclusion: There was a decrease in the extrinsic stain score after treatment and it showed that strawberry extract could affect saliva pH
