Tooth erosion is common problem and its prevalence is increasing in children. Children's penchant for consuming packaged drinks that have high acid content triggers tooth erosion. Tooth erosion is characterized by mineral solubility on the tooth surface due to consuming acidic foods and drinks continuously for a long time. The purpose of this study was to determine the difference in the calcium solubility of primary teeth after immersing in lemon juice (Citrus limon) and yogurt. This research method is experimental laboratory with post-test control group design using twenty-seven mandibular primary incisors which were divided into two groups (control and treatment). The treatment group was divided into six sub-groups, immersing in lemon juice for 6 hours, 12 hours, 18 hours and yogurt for 6 hours, 12 hours, 18 hours, while the control group was divided into three subgroups, immersing in artificial saliva. 6 hours, 12 hours and 18 hours. Testing the calcium solubility using an Atomic Absorption Spectrophotometer (AAS) then the differences between groups were analyzed using one way ANOVA. The results showed a significant difference, the solubility of calcium after immersing in lemon juice for 18 hours was 66.76 ppm and the solubility of calcium after immersing in yogurt for 18 hours was 22.07 ppm. So, it can be concluded that the calcium solubility in primary teeth after immersing in lemon juice is greater than yogurt.

Background: Health education games can be an effective way for elementary school children to increase their dental health knowledge and oral health. Purpose: This study aims to test the effectiveness of using reminder sticker books by showing the increase in dental health knowledge and improvement in the Simplified Oral Hygiene Index (OHI-S) in seven- to eight-year-olds. Methods: The study was quasi-experimental with a pretest-posttest group design and descriptive analysis method. It involved 54 elementary school students. A reminder sticker book was used to measure the levels of knowledge and oral hygiene. Intraoral examinations were conducted, and the children’s frequency of attaching stickers in the morning and afternoon was measured. Frequency was divided into three categories. A questionnaire measured the children’s levels of knowledge, which were divided into five categories. Results: The reminder sticker game increased dental health knowledge, with the mean of the control group at 64.4, and the treatment group at 92.5. OHI-S means were 1.68 for the control group and 0.78 for the treatment group. An independent t-test measured the levels of knowledge before and after the study. OHI-S and ANOVA tests measured the increase of dental health knowledge, which was divided into five categories, and decrease in the OHI-S index (divided into three categories). Conclusion: Reminder sticker books can increase oral health knowledge and reduce OHI-S scores in seven- to eight-year-old children.

Latar Belakang: Kesehatan rongga mulut pada anak tunanetra cenderung buruk karena tidak dapat mendeteksi gejala awal inflamasi gigi melalui indra penglihatan. Pemberian materi penyuluhan kesehatan gigi dan mulut dengan Braille merupakan penyesuaian agar anak tunanetra dapat memahami kesehatan rongga mulut dengan lebih baik. Tujuan: Mereview peran teks Braille terhadap peningkatan pengetahuan kesehatan gigi dan mulut anak tunanetra. Metode: Literature review bersumber dari 7 jurnal yang didapat melalui database online dengan kata kunci visually impaired children OR blind children AND Braille AND dental health education AND oral hygiene OR oral health knowledge. Hasil: Tingkat pengetahuan awal anak tunanetra terhadap sesama siswa tunanetra adalah rendah dan/atau sedang, sehingga potensi adanya peningkatan pengetahuan kesehatan gigi dan mulut dapat tercapai saat anak tunanetra berhasil untuk memahami penyuluhan yang diberikan dalam teks Braille. Kesimpulan: Pamflet atau booklet Braille diharapkan dapat meningkatkan pengetahuan kesehatan gigi dan mulut anak tunanetra dengan efektif.

Nano glass ionomer cement (GIC) with nano zirconia as a raw material called zirconium is a newly developed type of restoration/tooth filling material that is used in dentistry. Objective: To examine the effect of carbonated beverages on the surface roughness of Zirconomer and GIC filling materials and determine if there was any difference between them. Methods: This is a true-experimental laboratory research study with a pre-posttest group design. The research samples consisted of 32 samples, 16 GIC samples and 16 Zirconomer samples, further divided into four time-sensitive groups: day 1, day 3, day 5, and day 7. The samples were immersed in artificial saliva and carbonated beverages for 24 hours. Surface roughness was measured using a surface roughness tester. Results: The average surface roughness from day 1 to day 7 of the GIC material immersed in carbonated beverages was 4.17 μm, which is higher than the average surface roughness of Zirconomer (3.091 μm), and the difference was significantly different (pConclusion: Zirconomer was found to be more resistant to carbonated beverages than GIC. There was a positive correlation between the length of immersion time in the carbonated beverages and the surface roughness of GIC and Zirconomer.
