"Pendahuluan: Celah orofasial (COF) memerlukan perawatan palatoplasti untuk menutup fistula yang terdapat di palatum. Akan tetapi, pembentukan jaringan parut di area operasi berkaitan erat dengan gangguan pertumbuhan. Modifikasi teknik bedah dan pendekatan farmakologi telah diteliti untuk mengetahui efeknya terhadap pembentukan jaringan parut dan keberhasilan palatoplasti. Ikan gabus, Channa striata, merupakan salah satu ikan endemik Asia Tenggara yang secara empiris dipercaya dapat membantu penyembuhan, terutama pascamelahirkan. Sejumlah penelitian telah menunjukan efek dari ekstrak Channa striata terhadap penyembuhan luka, namun belum ada penelitian pada penyembuhan luka di palatum tikus. Penelitian ini bertujuan untuk melihat efek ekstrak Channa striata terhadap penyembuhan luka di palatum tikus secara histologis. Metode: Sebanyak 36 tikus Sprague dawley dibuatkan luka pada palatum dengan metode punch biopsy. Dari 36 tikus tersebut, dibagi dalam 3 kelompok, yaitu kelompok perlakuan dengan kombinasi topikal dan peroral ekstrak Channa striata, kelompok kontrol positif diberi gel gengigel dan suplemen vitamin C, dan kelompok kontrol negatif dirawat dengan gel tanpa bahan aktif. Kemudian dilakukan pengamatan pada hari ke-3, -7, dan - 14 setelah perlakuan secara klinis untuk mengamati luas luka mikroskopik. Sebanyak 4 tikus dari masing-masing perlakuan dinekropsi pada setiap hari pengamatan untuk dibuatkan preparat pengamatan histologis. Pewarnaan hematoksilin dan eosin dilakukan untuk mengamati panjang luka mikroskopik, reepitelisasi, dan angiogenesis, sedangkan pewarnaan Masson’s trichrome digunakan untuk mengamati kerapatan kolagen. Hasil dan Pembahasan: Pada hasil pengamatan ukuran luka, didapatkan bahwa terdapat perbedaan bermakna secara statistik (p<0,05) ukuran luka makroskopik pada hari ke-3 dan -14, reepitelisasi pada hari ke -7 dan -14, dan kerapatan kolagen pada hari ke-14. Di sisi lain, tidak terdapat perbedaan bermakna antarperlakuan pada pengamatan panjang luka mikroskopik dan angiogenesis. Ekstrak Channa striata terbukti dapat berdampak pada penyembuhan luka di palatum tikus. Kesimpulan: Berdasarkan penelitian ini, terlihat bahwa pemberian ekstrak Channa striata topikal dan peroral dapat mengurangi ukuran luka tikus, meningkatkan tingkat reepitelisasi, meningkatkan kerapatan kolagen, dan meningkatkan angiogenesis secara signifikan pada beberapa titik waktu yang diukur, tetapi efektivitasnya lebih rendah daripada gel gengigel dan vitamin C.

Introduction: Orofacial clefts (OFC) require palatoplasty treatment to close the fistulae present in the palate. However, scar tissue formation at the surgical site is closely associated with growth disturbance. Modification of surgical techniques and pharmacological approaches have been investigated for their effects on scar tissue formation and palatoplasty success. Snakehead fish, Channa striata, is one of the fish endemic to Southeast Asia that is empirically believed to aid healing, especially postpartum. A number of studies have shown the effect of Channa striata extract on wound healing, but there has been no study on wound healing in the palate of rats. This study aims to look at the effect of Channa striata extract on wound healing in the rat palate histologically. Methods: A total of 36 Sprague Dawley rats were wounded on the palate by punch biopsy method. The 36 rats were divided into 3 groups, namely the treatment group with topical and peroral combination of Channa striata extract, the positive control group was given gengigel gel and vitamin C supplement, and the negative control group was treated with gel without active ingredients. Then observations were made on day-3, -7, and -14 after clinical treatment to observe the microscopic wound area. A total of 4 rats from each treatment were necropsied on each observation day to make histological observation preparations. Hematoxylin and eosin staining was performed to observe microscopic wound length, re-epithelialization, and angiogenesis, while Masson's trichrome staining was used to observe collagen density. Results and Discussion: In the observation of wound size, there was a statistically significant difference (p<0.05) in macroscopic wound size on days 3 and 14, re-epithelialization on day 7 and 14, and collagen density on day 14. On the other hand, there was no significant difference between treatments in the observation of microscopic wound length and angiogenesis. Channa striata extract was shown to have an impact on wound healing in the rat palate. Conclusion: Based on this study, it was shown that topical and peroral administration of Channa striata extract can reduce the size of rat wounds, increase the rate of re-epithelialization, increase collagen density, and enhance angiogenesis significantly at several time points measured, but its effectiveness is lower than gengigel gel and vitamin C."

"Topical fluoridation recently has become the method of choice in caries prevention. Flouride plays an important role not only in the formation of fluoroapatite, but also promoting enamel remineralization. Enamel remineralization occur when the enamel environtment supersaturated with calcium and phospate ions. When the pH level decrease, the rise of H ions, the hydroxyl of the apatite will be drawn out from the enamel, and substitute by fluoride ion, this condition will causes apatite breakdown and both calcium and phosphate will be released to the enamel environment. The release of those minerals, will cause supersaturation and promoting enamel remineralization. In the nature fluoride can be found in the sea fishes, such like teri (anchovy, Stolephorus sp) fishes. Teri fish has about 17-38 ppm of fluoride content. The high fluoride content of teri fish, lead this research to know the influence of it's application to the enamel surface on remineralization process, measured with enamel surface roughness and hardness tests. Seven enamel discs, 5 x 10 mm (W and L) obtained from 4 impacted third molars, were used in the research. One disc used as initial control, and 6 discs divided into 2 groups, used as experiment groups. All of the experimental discs demineralized using 50% phosphoric acid, then 3 of them were applied with teri substrate, wether other 3 discs applied with non ionic aquadest. All experimental discs, then immersed in the remineralization solution containing calcium phosphate stabilized with caseinphosphoptide. The cycle above repeated for 26 times. Analize of the specimens, were done using surfcom for enamel roughness and Buehler microhardness tester for surface hardness. Surface roughness of the teri group is 1,78 um compare to the initial group (215 um), and enamel surface microhardness of the teri group is (376 VHN), significantly differ from the control group, 358 VHN. Conclusion: Based on this research result, it can be concluded that : Teri fish substrate application on enamel surface causes the enhancement of enamel remineralization, as evaluated by surface roughness and micro hardness."
