This study aimed to compare the effectiveness of strawberry extract with100%, 75%, 50% and 25% concentration in cleaning the extrinsic stain on the teeth. The sample of the study was 32 permanent anterior teeth that were already extracted, consisting of each 16 maxillary and mandibular anterior teeth and all samples have an extrinsic stain. The samples were randomly divided into 4 groups, each group consisting of 8 teeth was treated by applying the strawberry extract with the concentrations of 100%, 75%, 50% and 25%. After 5 minutes, the teeth were rinsed and dried. The study was conducted in vitro for five consecutive days with twice treatment daily. Intensity Score and Extension Score of the stain were measured using the Lobene Stain Index. All samples experienced a decrease in both the Intensity and Extension Scores, the largest decrease in Intensity and Extension Score were obtained from strawberry extracts with concentration of 100%. The significant decrease in the Intensity Score occurs on the third day and continues until the fourth and fifth days, while the significant decrease in the Extention Score occurs on the fourth day and continues until the fifth day. The four group of the strawberry extract concentrations gave a decrease in the score, which distinguishes the treatment frequency. The higher the concentration, the frequency would be less in lowering stain score, whereas at low concentration the decrease of score require more frequency.

Discoloration of teeth can be caused by stains on the surface of the teeth or due to changes in tooth material. Tooth stain can be extrinsic, intrinsic, or age-related. Tooth whitening (bleaching) can be done in the office and at home. Strawberry is a fruit with many benefits, one of which is whitening teeth. The content of malic acid and ellagic acid in strawberries has the effect of tooth whitening. The purpose of this study was to determine the effectiveness of strawberry extract with a concentration of 100% in cleaning teeth with the extrinsic stain on an academic member of the Health Polytechnic Jakarta I. This study was an experiment on 31 people who had upper and lower anterior teeth with the extrinsic stain as samples. Data collection was done by applying strawberry extract with a concentration of 100% on the surface of the anterior teeth, allowed to stand for 5 minutes, then brushed and rinsed with water. This procedure was done 2 times a day for 5 consecutive days. Changes in extrinsic stain were measured using the Lobene Stain Index which measures the intensity and area of the stain, as well as a combined score of both. The average combined score with measurements using the Lobene Stain Index for extrinsic stain before being treated with strawberries was 22.4. The score has decreased every day starting from day 1 to day 5 of treatment. The largest decrease of the average Combined Score was occurred on the 2nd day, namely from a score of 20.0 on the 1st day to 14.6 on the 2nd day with a percentage reduction of 35.0%. Statistical tests showed significant results of 0,000 reducing the Intensity Score and Area Score on day 2 to day 5. It can be concluded that there was a significant decrease in extrinsic stain scores after treatment on day 2. Keywords: extrinsic stain; strawberry extract

A quasi experiment pre-test and post-test without control group design involved 141 students as selected through purposive sampling. Samples were distributed to grade IV, V, and VI of private elementary school students in Depok, West Java, Indonesia in April-October 2016. Data collection used pre-test and post-test questionnaires. Data processing used Wilcoxon Signed Rank Test and regression logistic. Results showed the improvement of knowledge level after implementing "KakAyu Dental Flipbook" education. The average result of respondents' knowledge at pre-test was 80.85 ± 14.17, and 93.40 ± 9.84 at post-test. There is a relation between knowledge improvement and education using "KakAyu Oral Dental/Orthodonthic Flipbook" (p value = 0.001), but no significant relation between the variables (grade, age, sex, number of family members and mother's working status) and oral health knowledge improvement of elementary school students.Keywords: Dental flipbook, education, elementary school students, knowledge, oral health education Abstrak Perlu adanya edukasi untuk meningkatkan pengetahuan anak Indonesia tentang pentingnya memelihara kesehatan gigi dan mulut.
