Background : Topical fluoridation recently is still the main caries prevention method. Fluoride application on enamel surface is aimed to convert the hydroxyapatite (HA) crystal to fluoroapatite (FA) or hydroxyfluoroapatie (HFA) form. Fluoride retention and intrusion onto enamel after Fluoride application, therefore, are the most important factors to ensure the formation of FA and HFA crystals. Natural Fluoride sources can be obtained from sea fishes, like teri (anchovy) fish. Teri medan (S baganensis) and teri jengki (S insularis) are the most pupolar teri fishes in Indonesia, and they are known 10 have high fluoride content. 17-34 ppm. This research objectives are to measure fluoride retention and intrusion on enamel surface after application using teri medan and teri jengki substrate. Material and Method : 8 extracted third impacted molars were used. During the research, those teeth are immersed in ono-ionic aquadest (aquadem). Each tooth were cut bucco-lingually and mesio-diastally to obtain 4 enamel specimens. The specimens (totally 32) the divided into 3 major groups. 12 each for EDS group and intrusion groups and 8 for control. The EDS group divided Into 2 sub-groups for application with teri medan and teri jengki. Similar procedure were done for intrusion and control groups. All EDS and intrusion specimens then immersed in the 5% teri substrate for 5 minutes. Flushed with aquadem, then stored in aquadem for 3 hours. Procedure above then repeated 26 times. Control specimens were immersed in saline for 5 minutes, before flush and stored in the aquadem solution. All the EDS specimens examinated using LEO Scanning and micro analysis electron microscope. Intrusion groups evaluated with Olypus BX41TF fluorescence mocroscope. Results uorescence microscope. Results fluoride retention for teri jengki groups is 5.28%, and for teri medan group is 3.26%, while for control group is 1.94%. Fluoride intrusion for teri jengki group is 11.48 um, teri medan 8.74 um, and for control group is 0.84 um. Anova and Bonferroni test showed different result between experiment and control group and between teri jengki and teri medan group, both for retention and intrusion examinations. Conclusion : based in this research, it can be concluded that teri jengki and teri medan fishes substrate give better result on fluoride retention and intrusion on enamel surface, compared to the control group. Application using teri jengki substrale gives better fluoride retention and intrusion on enamel surface compare to the teri medan substrate appllication

Pendahuluan: Ikan teri jengki (Stolephorus insularis) mengandung fluor dalam bentuk senyawa CaF2. Tujuan: Menganalisis perubahan kekerasan mikro permukaan email setelah pemberian ikan teri jengki. Metode: Perlakuan dilakukan pada 9 gigi tikus Sprague dawley yang terbagi menjadi kelompok baseline, perlakuan pakan teri, perlakuan oles larutan teri, kontrol negatif pakan, dan kontrol negatif akuades. Hasil: Nilai kekerasan Vickers pemberian ikan teri jengki metode pakan (440.30 ± 24.72) dan oles (510.32 ± 35.72) lebih tinggi bermakna daripada kontrolnya (315.80 ± 17.51) dan (347.28 ± 28.56). Kesimpulan: Penggunaan ikan teri jengki metode oles lebih efektif dalam meningkatkan kekerasan email dibandingkan metode pemberian pakan.

Introductions: Anchovies (Stolephorus insularis) contain high enough fluor in the form of CaF2. Aim: To analyze the alteration of enamel microhardness after anchovy substrate application. Method: Treatment was done on 9 incisors of Sprague dawley rats, comprised from groups which were baseline, feeding application, topical application, negative control of feeding, and negative control of topical. Results: Vickers hardness number of anchovies consumption by feeding (440.3 ± 24.72) and topical solution (510.32 ± 35.72) is statistically higher than its negative control (315.80 ± 17.51) and (347.28 ± 28.56). Conclusion: The use of anchovy (Stolephorus insularis) by topical is proven more effective in increasing the microhardness of tooth enamel surface.

ABSTRAK
Silver Diammine Fluoride SDF memiliki kandungan fluor yang diketahui dapat menghambat proses demineralisasi email gigi dan dapat meningkatkan konsentrasi ion fluor dalam saliva dan urin. Tujuan : Menganalisis konsentrasi ion fluor dalam urin setelah aplikasi SDF pada email gigi. Metode: Urin dari empat subjek penelitian dikumpulkan sesaat sebelum, 30 menit setelah, 2 jam dan 3 jam setelah aplikasi SDF dan dianalisis konsentrasi ion fluornya dengan menggunakan alat Ion Selective Electrode. Hasil: Tidak ada perbedaan yang bermakna antara waktu 1 dan waktu 2, waktu 1 dan waktu 3, waktu 1 dan waktu 4, waktu 2 dan waktu 3 p>0.05 serta terdapat perbedaan yang bermakna antara waktu 2 dan waktu 4 serta waktu 3 dan waktu 4 p

ABSTRAK
Background Silver Diammine Fluoride SDF , which content fluoride is known to inhibit tooth enamel demineralization process and increase fluoride concentration in saliva and urine. Objective Analyzing the fluoride concentration in urine after application of SDF on tooth enamel. Methods Urine from four subjects were collected prior to application, 30 minutes after, 2 hours and 3 hours after application of SDF and use Ion Selective Electrode to measured the fluoride concentration. Result There is no significant difference between time 1 and time 2, time 1 and time 3, time 1 and time 4, time 2 and 3 p 0.05 and there is a significant difference between time 2 and time 4 also time 3 and time 4 p
