Periodontitis is inflammation of the periodontal tissue that can cause progressive damage to the periodontal ligament and alveolar bone. Clinical examination to determine the degree of damage to the alveolar bone using a periodontal probe instrument or probing. Cellular activity in the gingival crevicular fluid is thought to be a biomarker to determine the inflammatory status of the periodontal tissue. Cellular immune responses suggest the role of cytokines in the pathogenesis of gingivitis and periodontitis. The cytokines observed in this study were the protein Osteocalcin and Interleukin-1β (IL-1β) in the gingival crevicular fluid (GCF). In this study, 67 patients were examined for the condition of their periodontal tissues including the severity of gingivitis and periodontal probing. The gingivitis group was divided into 4 groups, namely normal, mild, moderate, and severe. Meanwhile, for probing samples were grouped based on probing into 3 groups. Group I (0-3 mm), group II (3.1-5 mm) and group III (> 5 mm). GCF was obtained using paper points that were left in the gingival sulcus for 30 seconds. Then paper points are put into cryovial tubes which are sent to the laboratory for ELISA test. The observed data on the expression of Osteocalcin and IL-1β were then performed statistical tests. Osteocalcin and IL-1β expression showed a significant difference with the severity of gingivitis cases. In the other hand, it did not show a significant difference with difference of periodontal pocket depth. Osteocalcin and IL-1β expression associated with the severity of gingivitis cases.

Mount Semeru in Lumajang-East Java erupted on Saturday 4 December 2021 at 15.15 WIB and affected 12 villages. One of the impacts caused by the eruption of Mount Semeru is the decline in the quality of life of the population seen from the health problems that arise, both general health and dental and oral health. The purpose of community service is to determine the prevalence of tooth decay and OHI-S score in elementary school children after the eruption of Semeru in Sumbermujur Village, Lumajang. Based on the results of dental and oral screening conducted on elementary school children who were affected by the disaster, it was found that the OHI-S score was in the good criteria (0.8-1.06), but the DMF-T score was in the low criteria (1.52-2.5). to moderate (3.7), and the dmf-t score is included in the criteria of moderate (3.0-3.89) to high (4.8-4.87). The cause of the high incidence of dental caries in elementary school students is the lack of knowledge of elementary school students about oral health, which can be concluded from the wrong behavior or way of brushing their teeth and the right knowledge about when to brush their teeth. Efforts that can be made to improve this behavior are education which is included in promotive and preventive efforts

Latar Belakang : Perubahan warna pada gigi dapat disebabkan oleh kebiasaan merokok, konsumsi kopi dan teh dalam jangka waktu panjang, obat-obatan serta fluorosis. Adanya perubahan warna gigi menyebabkan orang tidak nyaman saat tersenyum maupun berbicara. Penggunaan pasta gigi whitening menjadi upaya untuk mengatasi hal tersebut. Saat ini, penggunaan pasta gigi charcoal menjadi popular untuk mencerahkan warna gigi. Pasta gigi charcoal mengandung charcoal powder yang merupakan bahan abrasif. Penggunaan bahan abrasif sebagai pasta gigi dapat mempengaruhi permukaan enamel. Tujuan : Penelitian ini bertujuan untuk mengamati peningkatan kekasaran permukaan pada enamel gigi akibat penggunaan pasta gigi charcoal dan pasta gigi whitening. Metode : Penelitian eksperimental laboratoris dilakukan pada tiga puluh gigi premolar satu permanen rahang atas yang dibagi menjadi tiga kelompok sampel yang dilakukan penyikatan menggunakan bahan berbeda. Kelompok A: kelompok kontrol menggunakan distilled water, Kelompok B: pasta gigi whitening dan Kelompok C: pasta gigi charcoal. Penyikatan dilakukan dengan asumsi waktu setara penggunaan 1 dan 3 bulan. Nilai kekasaran permukaan pada enamel gigi sebelum dan setelah perlakuan diukur menggunakan Surface Roughness Tester Mitutoyo SJ-210. Hasil : Analisis statistik menggunakan repeated ANOVA menunjukkan perbedaan peningkatan kekasaran yang signifkan (p < 0,05) pada setiap kelompok setelah penyikatan dengan asumsi waktu sama dengan penggunaan 1 dan 3 bulan. Kesimpulan: Peningkatan kekasaran permukaan enamel akibat penggunaan pasta gigi charcoal lebih besar dibandingkan dengan penggunaan pasta gigi whitening

Latar Belakang: Cavit merupakan bahan tumpatan sementara gigi yang dapat beradaptasi dengandinding kavitas secara baik. Kelarutan bahan tumpatan sementara Cavit dapat dipengaruhi oleh cairan yangada di dalam rongga mulut seperti saliva, makanan dan minuman yang dikonsumsi sehari-hari. Bahantumpatan sementara Cavit akan mengalami kelarutan apabila terpapar oleh makanan atau minumandengan pH asam seperti kopi Arabika. Tujuan: Mengetahui pengaruh minuman kopi Arabika terhadapkelarutan bahan tumpatan sementara Cavit. Metode: Penelitian ini menggunakan desain penelitianExperimental laboratories dengan rancangan penelitian post test only control group design. Hasil: Analisisdata menggunakan uji One Way ANOVA menunjukkan nilai signifikansi ≤ 0.05 (0.000), sehingga terdapatperbedaan kelarutan bahan tumpatan sementara Cavit pada kelompok K1, P1, K2, P2. Kesimpulan:Berdasarkan penelitian ini, dapat diketahui bahwa lama waktu perendaman, minuman kopi Arabika yangbersifat asam, sifat bahan Cavit berupa kekerasan yang rendah berpengaruh terhadap kelarutan bahantumpatan sementara Cavit. Rata-rata nilai kelarutan paling tinggi terjadi pada bahan tumpatan sementaraCavit yang direndam dalam minuman kopi Arabika selama 21 jam. Rata-rata nilai kelarutan bahan tumpatansementara Cavit yang direndam dalam minuman kopi Arabika lebih tinggi dibandingkan dengan yangdirendam dalam saliva buatan.
