Latar belakang: ECC menjadi masalah serius di Indonesia dan Dunia. Terdapat 3komponen ECC, yaitu gigi, mikroba, serta lingkungan rongga mulut yang dalam hal iniyaitu protein saliva. Penyebab dari ECC sendiri yaitu bakteri Streptococcus mutans.Tidak hanya itu, Candida albicans sering dihubungkan dengan Streptococcus mutanspada plak ECC. Namun, adanya riset di mana Candida albicans cenderung mengurangisifat kariogenik Streptococcus mutans menarik untuk diteliti. Tujuan: menganalisisperan protein saliva ECC terhadap pertumbuhan biofilm Streptococcus mutans danStreptococcus mutans dan Candida albicans (atau dual-spesies) di rongga mulut.Metode: Setiap sampel dilakukan uji SDS-Page untuk melihat apakah terdapatperbedaan profil protein antar setiap sampel. Lalu, sampel dilakukan pengenceranmenjadi 3 konsentrasi, kemudian diinkubasi bersama dengan Streptococcus mutansserta dual-spesies di dalam 96-well plate selama 24 jam dan 48 jam secara anaerob.Lalu, masing-masing biofilm dilakukan uji Crystal Violet Staining (untuk mendapatkannilai Optical density) serta Total Plate Count. Hasil: Tidak terdapat perbedaan profilprotein antara saliva ECC dengan laju alir saliva <30 detik, 30-60 detik, 30-60 detikbebas ECC. Pada variabel konsentrasi protein, terdapat perbedaan dan kenaikan nilairerata pada nilai Optical density biofilm pada Streptococcus mutans dan dual-spesies.Tidak terdapat perbedaan secara statistik antara konsentrasi protein saliva denganviabilitas mikroba pada biofilm Streptococcus mutans dan dual-spesies meski nilairerata menunjukkan penurunan viabilitas mikroba. Pada biofilm Streptococcus mutansdan dual-spesies, tidak terdapat perbedaan bermakna pada hasil uji Optical density danviabilitas mikroba berdasarkan variabel waktu inkubasi biofilm. Meski nilai reratamenunjukkan adanya penurunan pada Optical density Streptococcus mutans, kenaikanpada viabilitas mikroba Streptococcus mutans, dan kenaikan pada Optical densitysekaligus viabilitas mikroba dual-spesies, namun tidak memengaruhi nilaikomparasinya. Kesimpulan: Protein saliva dapat memengaruhi pembentukan biofilmbaik Streptococcus mutans maupun kombinasi dual-spesies Streptococcus mutansdengan Candida albicans. Waktu inkubasi biofilm tidak dapat memengaruhipembentukan biofilm Streptococcus mutans maupun kombinasi dual-spesiesStreptococcus mutans dengan Candida albicans
Background: ECC is a serious problem in Indonesia and the world. There are 3components of ECC, namely teeth, microbes, and the oral environment, in this casesalivary protein. The cause of ECC itself is Streptococcus mutans. Not only that,Candida albicans is often associated with Streptococcus mutans in ECC plaques.However, the research in which Candida albicans tends to reduce the cariogenicproperties of Streptococcus mutans is interesting. Purpose: to analyze the role of theECC salivary protein on the growth of Streptococcus mutans and combination ofStreptococcus mutans and Candida albicans (or dual-species) biofilms in the oral cavity.Methods: Each sample was subjected to an SDS-Page test to see if there weredifferences in protein profiles between each sample. Then, the sample was diluted into 3concentrations, then incubated together with Streptococcus mutans and dual-species in96-well plates for 24 hours and 48 hours anaerobically. Then, each biofilm wassubjected to a Crystal Violet Staining test (to obtain Optical density value) and TotalPlate Count. Results: There was no difference in protein profile between salivary ECCwith salivary flow rates <30 seconds, 30-60 seconds, ECC-free 30-60 seconds. In theprotein concentration variable, there were differences and an increase in trend lines inthe Optical density value of biofilms in Streptococcus mutans and dual-species. Therewas no statistical difference between salivary protein concentrations and microbialviability in Streptococcus mutans and dual-species biofilms, although the trend lineshowed a decrease in microbial viability. In Streptococcus mutans and dual-speciesbiofilms, there were no significant differences in the Optical density test results andmicrobial viability based on the biofilm incubation time variables. Although the trendline showed a decrease in Optical density Streptococcus mutans, an increase inmicrobial viability of Streptococcus mutans, and an increase in Optical density as wellas dual-species microbial viability, it did not affect the comparative value. Conclusion:Salivary protein can influence biofilm formation for both Streptococcus mutans and thedual-species combination of Streptococcus mutans and Candida albicans. Biofilmincubation time could not affect the biofilm formation of both Streptococcus mutansand the dual-species combination of Streptococcus mutans and Candida albicans |
