Objective: This research aims to explore the potential of brown algae species padina sp. as a dental impression material by examining the physical characteristics of the sodium alginate extraction of brown algae species padina sp.
Material and Methods:This research is a quasi-experimental with one-shot case study design. Samples are brown algae species padina sp. from Punaga and Puntondo beach in South Sulawesi. Brown algae species padina sp. is extracted to obtain sodium alginate and further tested for physical characteristics including viscosity test and water content.
Results:The extraction of brown algae species padina sp. resulted in 250 grams (25%) of brown powdered sodium alginate that smelled fishy. Physical characteristic tests revealed the water content of sodium alginate species from brown algae padina sp. was 8%. This result is acceptable for sodium alginate water content as set by the Food Chemical Codex that requires less than 15% water content. The measurement of the viscosity obtained is 13.33 cps.
Conclusion:These results indicate that the species of brown algae padina sp. has the potential to be one of the basic materials of dental impression material.
The main function of teeth is chewing, whereas its capabilities depends on amount ofteeth remains. High teeth loss in elderly can compromise this chewing function,resulting in inadequate nutrition intake. Analytic epidemiology study of relationshipbetween dental status, diet pattern and nutrition intake in elderly of Buginese andMandarnese took 424 sample (Buginese 206; Mandarnese 216). Buginese dentalstatus showed higher prevalence of tooth loss 0-10 than Mandarnese (24.5%:18.1%),as for tooth loss 11-20 and 21-27, Mandarnese dental status showed higherprevalence than Buginese, and for total tooth loss Buginese showed higher prevalencethan mandarnese. Total mean tooth loss between Mandarnese and Buginese not somuch different, which is 20.42 to 19.58. Generally no significant diet patterndifference found between Buginese and Mandarnese. Diet pattern consist of foodprocessed to meet elderly chewing capabilities. Analysis of relationship betweendental status and macro nutrient carbohydrate and protein intake showed significantrelation (p<0.05), as for lipid intake showed relation although not significant.Analysis of relationship between dental status and micro nutrient Vitamin D, E, and Cstatically showed no significant relation, Vitamin A showed no relation at all.
Bahan pembersih gigi tiruan terbukti efektif mengurangi plak dan organisme mikro pada gigi tiruan. Akan tetapi penggunaan pembersih gigi tiruan dari bahan kimia selain mahal juga dapat menyebabkan kerusakan yang signifikan pada basis gigi tiruan karena pembersih gigi tiruan dapat menyebabkan hilangnya komponen larut dan peliat, atau penyerapan air oleh bahan basis. Berdasarkan hal tersebut penggunaan bahan alami, yaitu biji alpukat, menjadi pembersih alternatif. Pada penelitian eksperimen laboratorium ini menggunakan uji eksperimen dengan teknik disc diffusion. Bahan yang digunakan adalah varietas hijau panjang atau alpukat mentega yang diperoleh di perkebunan Malino, Sulawesi Selatan. Daya hambat diketahui berdasarkan pengukuran diameter zona inhibisi yang terbentuk di sekitar paper disc, dengan menggunakan jangka sorong. Hasil penelitian menunjukkan bahwa uji daya hambat ekstrak biji alpukat sangat signifikan, yaitu konsentrasi 2% dengan rata-rata 11,51 mm, konsentrasi 4% dengan rata-rata 12,39 mm, konsentrasi 6% dengan rata-rata 13,61 mm, konsentrasi 8% dengan rata-rata 13,53 mm, dan konsentrasi 10% dengan rata-rata daya hambat mencapai 15,02 mm. Luas zona tersebut melewati zona yang dihasilkan oleh Ampicillin sebagai kontrol positif, yaitu 14,22 mm. Disimpulkan bahwa biji alpukat memiliki aktivitas antibakteri yang cukup tinggi sehingga berpotensi sebagai antibakteri terhadap Streptococcus mutans.
