INTRODUCTION 14,15 However. pendans extract has not been known to decrease biofilm formation of periodontal pathogens such as S. sanguinis and T. Two common dental and oral health diseases are dental cariesAialso known as cavitiesAiand periodontal There are two main types of periodontal tissue inflammation gingivitis and periodontitis. 1 The inducer of these inflammation are bacterial species in sub-gingival Gingivitis, which is an inflammation on gingiva can be prevented by plaque removal, such as by brushing your teeth regularly. Periodontitis is marked by periodontal tissue damage and the loss of connective tissue attachments, alveolar bone loss, and pathological pockets surrounding the tooth. 2 One of the causes of this periodontal infection is biofilm. 3 Biofilm is a thin layer of microorganisms adhering to a solid surface and covered by a matrix of organic substances . olysaccharides, extracellular DNA . DNA), and protein. 4 The production of this extracellular matrix protects the bacteria from the surrounding area, including from chemotherapeutic agents. MATERIALS AND METHODS This study is an in vitro experimental laboratory with post-test only control design. This study was conducted in Microbiology Centre of Research and Education (MiCORE) laboratory. Faculty of Dentistry. Trisakti University. Jakarta. Indonesia. The plant used in this study was M. pendans which obtained from local society in Papua island which is located in eastern Indonesia. Myrmecodia pendans Extraction Dried M. pendans plant was washed in running water until clean and rinsed with aquadest to remove sticky soil on the plantAos surface. The dried sample was blended into a powder and sieved. Extracts were obtained from as much as 50 g of powder using a maceration technique, wherein the sample was soaked in 500 mL of 70% ethanol for 5 days. The sample was then left for 24h and filtered with filter paper. Filtrate was evaporated using a rotary evaporator at 40AC. The 100% . extract was diluted in brain heart infusion (BHI) broth (Thermo Scientific. Waltham. MA. USA) to 50%, 25%, 12. 5% and 25% . Streptococcus sanguinis is an anaerobic, facultative. Gram-positive bacterium found in the oral cavity that is involved in biofilm development. 6 S. sanguinis has a role in development of periodontal disease. 7 Treponema denticola is a common spirochete found in sub-gingival plaque and has a role in the development of chronic periodontitis, acute necrotizing ulcerative gingivitis (ANUG), infected root canal, and acute abscess. 8 These bacteria have some common virulence factors such as (MSP. , lipopolysaccharides (LPS. , dentilisin, peptidoglycan, cystalysin, peptidases, and phosphatases, which can cause inflammation and induce the host cell to produce chemical mediators, all of which involved in damaging periodontal connective tissues. Bacterial culture and Biofilm Assay test Brain heart infusion (BHI) broth was used to grow S. sanguinis and T. denticola ATCC 35405 and the bacteria were incubated at 37AC in an anaerobic atmosphere for 24h using GasPak jar system (Becton Dickinson. Franklin Lakes. NJ. USA). The bacterium culture in broth medium was measured at 600nm and diluted to obtain a suspension of McFarland standard 0. quivalent to 1,5x108 CFU/mL). After homogenizing, the bacterium suspension was distributed into a 96-well plate, and incubated at 37AC for 24h in an anaerobic atmosphere to formed biofilm. The supernatant was removed and the biofilm attached on the bottom of well plate was rinsed with phosphate buffer saline (PBS). uL M. pendans extracts with different concentrations . %, 50%, 25%, 12. 5% and 6. 25%) were distributed into the well plate. Chlorhexidine . 2%) was used for the positive control and biofilm wells without herbal tested was used for the negative control. Inhibitory effects were observed after incubation at 37AC for 1h, 3h 6h, and 24h in an anaerobic atmosphere. Crystal violet dye . 5% w/. was distributed into the well plate and incubated for 15 min. The extraction of the remaining crystal violet dye in the well plate was measured after the addition of 200 AAL 90% ethanol and the absorbance was measured using a microplate reader at 595 nm. About 70-80% of the worldAos population uses herbal and natural ingredients for health care, prophylaxis, and oral lesion treatment. The most populated countries, such as China and India, have been using natural remedies for over 2000 years to cure oral diseases, including periodontal disease. 10 For example, pineapple stem extracts contain high levels of bromelain, an enzyme which acts as an antibacterial agent against Enterococcus 11 Strawberry extracts have been proven to delay biofilm formation of E. faecalis and Porphyromonas gingivalis in vitro. 12 Pomegranates contain significant amounts of ellagic acid, which displays antibacterial activity against Candida albicans. 13 Myrmecodia pendans . nt nest plan. is a plant from Papua in eastern Indonesia, where it is well known as herbal remedy. pendans is commonly used in western Papua as a traditional medicine for many diseases. 14 Previous studies showed that ant nest plant extracts display antimicrobial activity towards Streptococcus mutans and E.

A maceration technique was used to acquire the ant nest plant extract. It is an active substance retrieval performed by soaking a simplified powder in a solvent for some days at room temperature and protected from the light. The solvent will penetrate into the cell wall of the simplified powder and infiltrate the cell cavity which contains the active substances. These active substances will be dissolved due to the different concentrations of solvent inside and outside the cell, causing the concentrated solvent to be pushed out. This process was repeated until a balanced concentration of the solvent was achieved inside and outside the cell. The advantage of the maceration technique is that it uses simple tools and it does not destroy heat-sensitive active substances. CONCLUSION Based on this study, it can be concluded that Myrmecodia pendans extract has an antibiofilm effect on sanguinis and T. denticola biofilm as mono and Ant nest plant (M. extract may be used as an alternative antibacterial agent to inhibit bacterial activities in the oral cavity. Future studies are needed to evaluate the potential of ant nest plant extract. CONFLICT OF INTEREST The authors declare that they have no conflicts of Previous studies that were done by Roslizawaty et , in 2013 showed that M. pendans decreased C. albicans growth. From the saturation level in test tubes of fungus and M. pendans, it was proven that there was an increasing inhibitory effect of ant nest extract on C. albicans at higher concentrations. 18 M. pendans belongs to the Rubiaceae family. It contains many active phytochemicals, mostly phenolic compound groups such as flavonoids, tannins, saponins, phenolic acids, alkaloids, triterpenoids, and glycosides. 19 M. displays two antibacterial mechanisms, which are cytotoxicity and apoptosis. Cytotoxicity is a characteristic that can slow and prevent microbial cell growth, which has potential to harm healthy host cells. 14,20 REFERENCES
