Abstract

Backgorund: Saliva contains several protein elements, exocrine proteins and antibodies, such as lactoferrin, sIgA, peroxidase, albumin, polypeptides, and oligopeptides that contribute to the defense of oral mucosa and dental pellicle to prevent infection caused by oral micropathogen, such as Candida albicans, Streptococcus mutans and Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans). Those micropathogens have a role to change salivary pH as an indicator of oral disease activities. Purpose: This study was aimed to analyze the changes of artificial saliva pH after interaction with S. mutans, C. albicans, and A. Actinomycetemcpmitans. Methods: The materials used in this study consist of S. mutans (ATCC 31987), C. albicans (ATCC 10231), A. actinomycetemcomitans (ATTC 702 358), and artificial saliva. To examine the pH changes of artificial saliva, those three microbiotas were cultured and incubated for 24 hours. Results: The results showed that the interactions of S. mutans, C. albicans, and A. actinomycetemcomitans in the artificial saliva can change the salivary on neutral. There were no significant difference with the control treatment salivary pH 4, 5, 6, 8, and 9 (p>0.05). Similarly, there was also no significant difference when those three microorganism interacted each other in the artificial saliva (p<0.05). Conclusion: It can be concluded that the biological activity of S. mutans, C. albicans, and A. actinomycetemcomitans in artificial saliva can change the salivary pH into neutral. It indicates that those microbiotas mutually supported and cooperated in influencing the biological cycle of the oral cavity with salivary pH as an indicator.Latar belakang: Saliva merupakan cairan eksokrin yang mengandung unsur protein dan antibodi seperti sIgA laktoferin peroksidase, albumin, polipeptida dan oligopeptida yang berperan pada pertahanan mukosa rongga mulut dan gigi guna mencegah infeksi oral mikropatogen seperti C. albicans, S. mutans, dan A. actinomycetemcpmitans. Patogenesis ketiga oral mikropatogen tersebut diawali dengan mempengaruhi perubahan pH saliva sebagai langkah invasi dan infeksi pada mukosa oral dan pelikel gigi. Tujuan: Penelitian ini bertujuan untuk untuk mengetahui perubahan pH saliva buatan setelah diinteraksikan dengan S. mutans, C. albicans, dan A. Actinomycetemcpmitans. Metode: Materi penelitian ini berupa Streptococcus mutans strain ATCC 31987, Candida albicans strain ATCC 10231, Aggregatibacter actinomycetemcomitans strain ATTC 702358, dan saliva buatan. Untuk mengetahui perubahan pH saliva, maka ketiga mikrobiota tersebut dikultur dan untuk menguji perubahan pH saliva dilakukan uji interaksi ketiga mikroorganisme tersebut dalam saliva buatan selama 24 jam dengan pengaturan pH saliva sebagai indikator hasil penelitian. Hasil: Hasil penelitian menunjukkan interaksi S. mutans, C. albicans, dan A. actinomycetemcomitans dalam saliva buatan mampu mereduksi perubahan pH saliva mengarah ke pH netral dengan kontrol perlakuan pH saliva 4, 5, 6, 8, dan pH 9 secara statistik tidak tidak menunjukkan perbedaan bermakna (p>0,05), begitu juga ketika dilakukan interakasi diantara masing-masing mikroorganisme tersebut dalam saliva buatan menunjukkan adanya perbedaan bermakna (p<0,05). Kesimpulan: Dapat disimpulkan bahwa aktivitas biologi S. mutans, C. albicans, dan A. actinomycetemcomitans dalam saliva buatan mampu merubah pH Saliva sekaligus mempertahankan pH netral. Hal ini menggambarkan bahwa mikrobiota tersebut saling mendukung dan bekerjasama dalam mempengaruhi siklus biologi rongga mulut dengan pH saliva sebagai indikator.

Abstract

Background: Enterococcus faecalis (E. faecalis) is a gram positive oral pathogen that reported at the main agent infection of endodontic treatment. Its activities are influenced by the virulence factors facilitating the interaction process between agents with host cells. Like aggregation substance, cytolysin, extracellular superoxide, gelatinase, hyaluronidase, sex pheromones, and surface adhesions molecules. Plant extracts are reported as the material antibacterial as well as E. faecalis in pathogenesis of endodontic infections. Purpose: Purpose of this study was to analyse of sarang semut extracts (Myrmecodia Pendens Merr. & Perry) towards sensitivity of E. faecalis. Method: This research used the methanol extract of sarang semut, E. faecalis ATCC 29212, and fosfomycin also chlorhexidine as the positive controls. Whereas, Bradford protein method was measured the concentration of the surface protein of E. faecalis and active component of the sarang semut extract. Result: Generally, the sarang semut extract possessed low sensitivity toward E. faecalis (≤ 13 mm), but on the concentrations of 100 µg/ml and 75 µg/ml better than inhibition of other concentrations, round 10.6-11.6 (mm). Specifically, on 100 µg/ml has indicator the minimal bactericidal concentration (MBC) on E. faecalis. Whereas minimal inhibition concentration (MIC) on the concentration of 3,125 µg/ml. Conclusion: Based on MBC and MIC assay, the extract of sarang semut has potential effects to adherence growth of E. faecalis, mainly on the highest concentration 100 µg/ml also MIC on 3,125 µg/ ml.
