Pendahuluan: Gigi yang masih vital memiliki ketahanan yang paling tinggi, diikuti pasak prefabricated resin fiber, dan pasak prefabricated stainless steel. Bahan pasak logam memiliki sifat mekanik seperti modulus elastisitas yang tinggi daripada bahan pasak non logam yang mempengaruhi kekuatan impak bahan pasak. Kekuatan impak adalah energi yang diperlukan untuk mematahkan suatu bahan dengan gaya benturan. Penelitian ini bertujuan untuk mengetahui perbedaan kekuatan impak antara mahkota pasak prefabricated logam berbahan titanium dengan mahkota pasak prefabricated non logam bahan resin fiber. Metode: Sebanyak 6 sampel gigi premolar dengan mahkota pasak prefabricated berbahan resin fiber. dengan rahang atas yang telah diobturasi dan dibagi kedalam 2 kelompok: kelompok I adalah kelompok yang akan diberikan pasak prefabricated bahan resin fiber (n=3), kelompok II dengan pasak prefabricated bahan titanium (n=3), kemudian ditumpat dengan bahan core build-up dari komposit. Semua kelompok ditanam di balok besi yang berbentuk persegi panjang. Selanjutnya dilakukan uji impak menggunakan mini impact tester tipe KRY sampai sampel patah. Hasil: Rerata kelompok pasak prefabricated bahan resin fiber adalah 1,9267 ± 0,99203 J/mm2 sedangkan kelompok pasak prefabricated bahan titanium adalah 5,7567 ± 0,41477 J/mm2. Independent sample t-test menunjukkan terdapat perbedaan pada semua kelompok. Simpulan: Kekuatan impak mahkota pasak prefabricated logam berbahan titanium lebih tinggi daripada kekuatan impak mahkota pasak prefabricated non logam berbahan resin fiber.Kata kunci: Kekuatan impak, pasak prefabricated logam, titanium, pasak prefabricated non logam, resin fiber. ABSTRACTIntroduction: Vital teeth are having the highest strength followed by prefabricated fibre resin post, and prefabricated stainless steel post. The metal post has higher mechanical properties such as its high elastic modulus rather than a non-metallic post which affects the material impact strength. Impact strength defined as the energy required to break material with impact force. This study was aimed to determine the difference between the impact strength of prefabricated metal post crown made of titanium and prefabricated non-metal post crown made of fibre resin. Methods: Six obturated mandibular premolars with prefabricated fibre resin post were divided into two groups: Group I was given a prefabricated fibre resin post (n = 3); group II was given a prefabricated titanium post (n = 3). They were all then filled with build-up core composite material. All groups were planted in a rectangular iron block. Furthermore, the impact test was performed using a mini-impact tester (KRY type) until all samples were broken. Result: The average impact strength of the post crown with prefabricated fibre resin material was 1.9267 ± 0.99203 J/mm2, while prefabricated titanium was 5.7567 ± 0.41477 J/mm2. Independent sample t-test showed that there were differences in all groups. Conclusion: The impact strength of the prefabricated metal post crown made of titanium was higher than the impact strength of the prefabricated non-metal post crown made of fibre resin.Keywords: Impact strength, prefabricated metal post crown, titanium, prefabricated non-metal post crown, fibre resin.

Background: Softliner is commonly used to provide convenience for edentulous patients. However, the use of softliner can cause denture stomatitis due to colonization of Candida albicans. Sargassum sp. contains active compounds of steroids, alkaloids, phenols, triterpenoids, act as antibacterial and antifungal. The use of Sargassum sp. in the form of effervescent as a denture cleanser can prevent denture stomatitis, and it’s expected not to affect the compressive strength. This study aimed to study the concentration variation of Sargassum sp. effervescent towards antifungal and compressive strength silicone based softlinerMethod: 20 sampels of silicone based softliner (10x3x2mm) divided into 5 groups. K(-) soaked in sterilled aquadest; K(+) in Polident solution; P1 in 10% effervescent Sargassum sp. solution; P2 20% ; P3 40%, for 15minutes. Candida calculated by colony counter (CFU/ml). Compressive strength measured by Universal Testing Machine.Result: Candida albicans in the K+ group is the lowest, while the K- group shows the highest value. In P1, P2, P3 group the value of Candida albicans is higher than K+ group, but much lower than K-. The compressive strength of K+ group shows the lowest value but in P3 group shows the highest value compared to other groups.Conclusion: The 10% concentration of effervescent extract Sargassum sp. is effective in reducing the number of Candida albicans in silicone based softliner compared to the K- group. The most effective concentration of effervescent extract Sargassum sp. in reducing the Candida albicans’ growth is 40%. The higher concentration of Sargassum sp. resulting in higher compressive strength.

Kesehatan gigi dan mulut di Indonesia masih merupakan masalah kesehatan yang perlu diperhatikan. Berdasarkan Riskesdas 2018, dilaporkan bahwa prevalensi masalah gigi dan mulut di Indonesia masih sangat tinggi. Sebanyak 57,6 persen orang Indonesia memiliki masalah gigi dan mulut. Hal yang paling memperhatinkan adalah sebanyak 93% anak-anak usia sekolah mengalami masalah gigi dan mulut. Kegiatan ini ditujukan sebagai program sekolah yang komprehensif di Indonesia, yang terdiri dari program 21 hari kesehatan gigi dan mulut pada anak di sekolah. Pelaksanaan Program Kesehatan Sekolah ini mengunakan sistem online melalui aplikasi zoom. Target peserta adalah 5 orang tua dan 5 guru di SD Hangtuah 6 Surabaya. Untuk lokasi dan waktu pelaksanaan adalah Sabtu, 5 November 2022, pukul 08.30 – 11.00 WIB dengan pelaksanaan menggunakan zoom meeting. Hasil analisis statistik menggunakan paired sample t-test nilai signifikansi 0.000, hal ini berarti bahwa terdapat perbedaan yang signifikan pada tingkat pengetahuan menjaga kesehatan gigi dan mulut pada guru pengajar dan orang tua murid di SD Hangtuah 6 sebelum diberi materi DHE dan sesudah diberi DHE melalui “Training of Trainer”. Guru dan orang tua dapat menjadi pioner dalam menyebarluaskan ilmu dan cara menjaga kesehatan gigi dan mulut bagi anak tingkat sekolah, juga untuk mengubah perilaku menjaga kesehatan gigi dan mulut menjadi lebih baik.
