Abstract

Abstract: Acrylic resin material is often used in making dentures because the color is similar to gingiva, easy to process, small dimensional changes, and relatively cheap price. One of the conditions that must be met is that the final product is easy to polish. Snail shell can be used as an abrasive for polishing acrylic plates because it contains protein, phosphorus and calcium. This study aimed to find out whether snail shell (Lissachatina fulica) powder as an abrasive material could reduce the roughness of acrylic surfaces. This was a laboratory and experimental study. Samples of acrylic resin plates were divided into three groups, group A was polished using sandpaper, group B was polished using pumice, and group C was polished using snail shell powder. Each group had nine samples of acrylic resin plates. Surface roughness of samples was tested with scanning electron microscope (SEM). The results showed that the surface of group C samples was the smoothest compared to the other groups tested with SEM. In conclusion, snail shell (Lissachatina fulica) powder can be used as an abrasive material to reduce the roughness of acrylic surfaces. Keywords: snail shell; surface roughness; acrylic resin plate   Abstrak: Bahan resin akrilik sering digunakan dalam pembuatan gigi palsu karena warnanya mirip dengan gingiva, mudah diolah, perubahan dimensi kecil, dan harganya relatif murah. Salah satu syarat yang harus dipenuhi ialah produk akhir mudah dipoles. Cangkang bekicot dapat digunakan sebagai abrasif untuk memoles pelat akrilik karena mengandung protein, fosfor dan kalsium. Penelitian ini bertujuan untuk mengetahui apakah cangkang bekicot (Lissachatina fulica) sebagai bahan abrasif dapat mengurangi kekasaran permukaan akrilik. Sampel pelat resin akrilik dibagi menjadi tiga kelompok, kelompok A dipoles menggunakan amplas, kelompok B dipoles menggunakan batu apung, dan kelompok C dipoles menggunakan serbuk cangkang bekicot. Setiap kelompok memiliki sembilan sampel pelat resin akrilik. Kekasaran permukaan sampel diuji dengan scanning electron microscope (SEM). Hasil penelitian menunjukkan bahwa permukaan sampel golongan C paling halus dibandingkan dengan kedua kelompok lainnya. Simpulan penelitian ini ialah serbuk cangkang bekicot (Lissachatina fulica) dapat digunakan sebagai bahan abrasif. Kata kunci: cangkang bekicot; kekasaran permukaan; plat resin akrilik

Abstract

Consumption of sugary, acidic, and refined carbohydrate-rich foods and drinks is a major cause of tooth decay, increasing dental caries among children. This community service program aims to raise awareness, especially among school-aged kids, about the dangers of such snacks. Through an educational approach, leaflets about harmful snacks like candy, soda, and other sugary treats were distributed. Pre- and post-intervention questionnaires measured participants' understanding. Initially, most children were unaware of the dental health risks of sugary snacks. After the intervention, knowledge about toothdecay-causing snacks increased by 95%, alongside a better grasp of healthy habits to maintain dental health. Early education on proper food choices and dental care can reduce dental caries prevalence among children. This program successfully boosted dental health awareness in the elementary school environment.

Abstract

ABSTRACT  Introduction: A traumatic ulcer is an open wound on the skin or mucous membranes that often results from trauma, such as scratches, bites, shocks, or pressure. Rain tree leaves (Samanea saman) have the potential to reduce pain and anti-inflammatory effects thanks to the flavonoid content. This extract works by inhibiting the cyclooxygenase and lipoxygenase pathways, which help limit inflammation and accelerate wound healing. This study aims to evaluate the effects of a 12% concentration rain tree leaf (Samanea saman) extract gel on fibronectin expression in the process of healing traumatic ulcers. Methods: This experimental laboratory study employed a post test only control group design. The sample consisted of male white rat wistar Rattus norvegicus and a gel of rain tree leaf extract extracted with a 98% ethanol solvent using a maceration method with a 12% concentration. Data analysis was performed using the Mann- Whitney U test. Results: The highest average was observed in the treatment group receiving the 12% rain tree leaf extract gel (Samanea saman), with an average value of 54.078, while the lowest average was found in the placebo gel control group, with a value of 22.462. Statistical analysis using the Mann-Whitney U test revealed a significant difference between groups (p = 0.004, p < 0.05). Conclusion: A 12% concentration of rain tree leaves (Samanea saman) extract gel significantly enhances fibronectin expression, contributing to the healing process of traumatic ulcers. KEY WORDS: Traumatic ulcers, fibronectin, rain tree leaf extract gel (Samanea saman), wound healing process. Antiinflamasi gel ekstrak daun trembesi (Samanea saman) terhadap ekspresi fibronektin: studi eksperimental ABSTRAK Pendahuluan: Ulkus traumatikus adalah luka terbuka pada kulit atau mukosa yang sering disebabkan oleh trauma seperti goresan, gigitan, benturan, atau tekanan. Daun trembesi (Samanea saman) memiliki potensi mengurangi nyeri dan efek anti-inflamasi berkat kandungan flavonoid. Ekstrak ini bekerja dengan menghambat jalur siklooksigenase dan lipooksigenase, yang membantu membatasi peradangan dan mempercepat proses penyembuhan luka. Tujuan penelitian ini untuk mengetahui peranan gel ekstrak daun trembesi (Samanea saman) dengan konsentrasi 12 % terhadap ekspresi fibronektin pada proses penyembuhan ulkus traumatikus. Metode: Eksperimental laboratoris dengan desain penelitian post test only control group. Sampel menggunakan hewan coba tikus putih jantan wistar Rattus norvegicus dan gel ekstrak daun trembesi yang diekstraksi dengan pelarut etanol 98% menggunakan metode maserasi dengan konsentrasi 12 %. Analisis data menggunakan uji Mann- Whitney U. Hasil: Rata-rata tertinggi ditemukan pada kelompok perlakuan yang menerima gel ekstrak daun pohon trembesi 12% (Samanea saman), dengan nilai rerata sebesar 54,078, sedangkan rata-rata terendah ditemukan pada kelompok kontrol gel plasebo, dengan nilai sebesar 22,462. Uji Mann-Whitney U menunjukan bahwa terdapat perbedaan yang signifikan dengan nilai signifikan n 0,00 < 0,05. Simpulan: Pemberian gel ekstrak daun trembesi (Samanea saman) 12% berpengaruh terhadap ekspresi fibronektin pada proses penyembuhan ulkus traumatikus. KATA KUNCI: Ulkus Traumatikus, fibronektin, gel ekstrak daun trembesi (Samanea saman), proses penyembuhan luka.
