ABSTRAK Kanker rongga mulut/karsinoma sel skuamosa rongga mulut (OSCC) yang berasal dari epitel rongga mulut bersifat invasif dan bermetastasis. Salah satu protein yang berperan dalam menjaga adhesi sel dalam pembentukan kanker adalah E-cadherin. E-cadherin memiliki peran penting dalam embriogenesis, bertindak sebagai molekul penekan tumor invasif. Pengobatan yang dilakukan terhadap kanker yang invasif dan bermetastasis adalah kemoterapi dan radioterapi, tetapi pengobatan ini memiliki efek samping yang tidak diinginkan. Untuk itu diperlukan pengobatan alternatif, seperti pengobatan menggunakan bahan-bahan alami. Ganoderma lucidum (G. lucidum) diyakini dapat meningkatkan ekspresi E-cadherin sebagai anti kanker alami dan memiliki kemampuan sitotoksik dan anti-angiogenik, menginduksi apoptosis, merangsang respon imun dengan meningkatkan level limfosit CD3, CD4, dan CD8, dan merupakan antioksidan. Tujuan penelitian ini adalah mengetahui ekspresi E-cadherin pada kultur OSCC (KB CCL-17) yang diberikan ekstrak etanolik isolat G. lucidum Cianjur. Penelitian ini merupakan penelitian eksperimen dengan desain post-test only dan kelompok kontrol. Kelompok perlakuan menggunakan ekstrak etanol G. lucidum dengan konsentrasi 2,12 µg/mL (P1), 4,24 µg/mL (P2), dan 8,49 µg/mL (P3). Kelompok kontrol positif menggunakan Cisplatin dengan konsentrasi 11,5 µg/mL (K1) dan kelompok kontrol negatif menggunakan akuades (K0). Ekspresi E-cadherin diamati dengan pemeriksaan imunohistokimia. Laju ekspansi E-cadherin tertinggi pada kelompok perlakuan dengan konsentrasi ekstrak etanol G. lucidum 8,49 g/mL. Uji one-way ANOVA menunjukkan perbedaan yang nyata (p<0,05) antara K0 dan P2, K0 dengan P3, K1 dengan P2, K1 dengan P3, P1 dengan P2, P1 dan P3. Ekspresi E-cadherin pada kultur karsinoma sel skuamosa (KB-CCL-17) dapat dipengaruhi oleh ekstrak etanol isolat G. lucidum Cianjur pada konsentrasi 2,12 g/mL, 4,24 g/mL, dan 8,49 g/mL. Kata kunci: E-cadherin, Ganoderma lucidum, KB CCL-17 ABSTRACT Oral cancer/oral squamous cell carcinoma (OSCC) originating from the oral epithelium is invasive and metastasized. One protein that plays a role in maintaining cell adhesion in cancer formation is E-cadherin. E-cadherin has an important role in embryogenesis, acting as a tumor invasive suppressor molecule. Treatment committed against invasive and metastatic cancer is chemotherapy and radiotherapy, but these treatments have undesired side effects. Therefore, an alternative treatment is desperately needed, such as that using natural materials. Ganoderma lucidum (G. lucidum) is believed to increase E-cadherin expression as a natural anti-cancer and has the cytotoxic and anti-angiogenic ability, induces apoptosis, stimulates the immune response by increasing the level of CD3, CD4, and CD8 lymphocytes, and is an antioxidant. The study aimed to determine the expression of E-cadherin in OSCC culture (KB CCL-17) treated by an ethanolic extract from Cianjur isolate of G. lucidum. This study was an experimental study with a post-test only with a control group design. The treatment group used ethanol extract of G. lucidum at a concentration of 2.12 µg/mL (P1), 4.24 µg/mL (P2), and 8.49 µg/mL (P3), respectively. The positive control group used Cisplatin with a concentration of 11.5 μg/mL (K1) and the negative control group used aqua dest (K0). E-cadherin expression was observed by immunohistochemical examination. The highest e-cadherin expansion rate was in the treatment group with the concentration of ethanol extract of G. lucidum 8.49 µg/mL. One-way ANOVA test showed a significant difference (p <0.05) between K0 and P2, K0 with P3, K1 with P2, K1 with P3, P1 with P2, P1, and P3. E-cadherin expression in squamous cell carcinoma culture (KB-CCL-17) can be affected by ethanol extract from Cianjur isolate of G. lucidum at a concentration of 2.12 µg/mL, 4.24 µg/mL, and 8.49 µg/mL.

Ameloblastoma is the most common odontogenic tumour as it usually does not form metastasis, it is considered as benign tumour with a locally invasive growth pattern and destruction of the jaw and the surrounding tissue. Ameloblastoma annual incidence is 0.5 per 1.000.000 people, higher incidences are found in Africa, China and India in comparison with the western countries. About 80% of ameloblastomas are located in mandible, mainly in the third molar region, and 20% in the maxilla, particularly in the posterior region. Unicystic ameloblastoma is associated with a smaller relapse risk and is the only type that is susceptible for conservative surgery. Standar treatment for ameloblastoma today is radical resection with 1 cm resection margins. Recurrence range from 0 to 15% conservative surgery including enucleation and curettage recurrence rets as high as 55%. Recurrence ameloblastoma problem are associated with development of metastasis and transformation into ameloblastic carcinoma. Segmental resection with adequate margins followed by reconstruction with AO Plat the most ideal form of treatment available. Dentoalveolar rehabilitation is recommended in all such patients to improve final outcome. Keywords: Ameloblastoma, Segmental Resection, Reconstruction
Kesehatan gigi dan mulut anak di Indonesia masih didominasi oleh penyakit karies gigi. Prevalensi perawatan gigi merupakan hal yang sulit dilakukan oleh anak usia 3-5 tahun karena anak pada usia ini masih harus dibimbing untuk membedakan mana yang benar dan mana yang salah. Faktor yang sangat berpengaruh pada kesehatan gigi dan mulut anak balita yaitu dari tingkat pengetahuan ibu. Pengetahuan dapat ditingkatkan melalui penyuluhan. Penyuluhan dengan metode ceramah dapat mudah diterima dengan dibantu kombinasi tambahan media. Media Audio Visual merupakan salah satu alat peraga yang bersifat dapat didengar dan dapat dilihat yang dapat membantu dalam belajar mengajar yang berfungsi memperjelas atau mempermudah dalam memahami bahasa yang sedang dipelajari. Tujuan penelitian ini untuk mengetahui pengaruh pemberian penyuluhan dengan media video edukasi terhadap pengetahuan kesehatan gigi dan mulut balita pada ibu di wilayah kerja Puskesmas Purwokerto Utara I. Penelitian ini menggunakan jenis penelitian pre eksperimental dengan rancangan penelitian yang digunakan yaitu one group pre and posttest design tanpa dilakukan adanya kelompok pembanding. Sampel dilakukan pada ibu yang datang sambil melakukan imunisasi balitanya di Puskesmas Purwokerto Utara I. Kegiatan penyuluhan dilakukan dengan metode individual kepada ibu yang datang secara bergantian sambil melakukan imunisasi di Puskesmas Purwokerto Utara I. Jumlah ibu yang berkenan mengisi kegiatan hingga akhir dari mulai pre test, penyuluhan, dan post test yaitu sebanyak 20 orang. Berdasarkan hasil penelitian menunjukkan bahwa pemberian penyuluhan kesehatan gigi dan mulut dengan kombinasi metode cerama dan media video edukasi dapat berpengaruh terhadap pengetahuan ibu di wilayah Puskesmas Purwokerto Utara I sebesar 30,3%.
Intercellular adhesion plays a role in cancer formation and protein has a key potential in maintaining cell adhesion, including syndecan-1. Meanwhile, oral cancer originates from the oral epithelium, which has an invasive and metastatic level. Its treatments involving chemotherapy and radiotherapy commonly leave unfavorable side effects, hence, suitable alternatives are needed. Natural ingredients are widely used as an alternative treatment for cancer, for example, Ganoderma lucidum (G. lucidum) which has anti-cancer and anti-angiogenic properties, induces apoptosis, stimulates an immune response, inhibits the degradation of Extracellular matrix (ECM), reduces inflammation, affects cell cycles, cytotoxic, and acts as an antioxidant.This study aims to determine the effect of ethanol extract from Ganoderma lucidum Cianjur isolate on syndecan-1 expression in KB CCL-17 oral cell cancer. This was an experimental study with a post-test only control group design, the treatment group used G. lucidum ethanol extract with a concentration of 2.12 μg/ml (P1), 4.24 μg/ml (P2), and 8.49 μg/ml (P3), while the positive control group used cisplatin with a concentration of 11.5 μg/ml (K1). In contrast, the negative control used aquadest (K0), while syndecan-1 expression was observed using the immunohistochemical examination.The highest syndecan-1 expansion rate was found in the treatment group with a concentration of 8.49 μg/ml. A significant difference was indicated by one-way ANOVA (p<0.05) between K0 - K1, K0 - P1, K0 - P2, K0 - P3, K1 - P1, K1 - P2, K1 - P3, P1 - P2, as well as P1 and P3. The administration of ethanol extract from G. lucidum Cianjur isolate increases syndecan-1 expression in KB CCL-17 oral cell cancer.
