Oral candidiasis is the third major opportunistic infection in people with HIV/AIDS. The antifungal has a very important role to prevent candidemia. But the use of antifungal has developed resistancy, for this reason it is important to find other high potent and cost effective antifungal. In this study Aloe vera was choosen because of its beneficial properties which has already been proven scientifically. The objective of the study was to investigate antifungal effect by finding the minimal inhibitory concentrations (MICs) and minimal fungicidal concentrations (MFCs) of Aloe vera leaf to Candida albicans isolated from oral cavity of HIV/AIDS patients, and to Candida albicans ATCC 10231 strain as the control group. Ethanol was used for the extraction of the leaf after obtaining the gel from it. MICs and MFCs were tested by tube dilution technique. Eight identified samples of Candida albicans isolated from oral cavity of HIV/AIDS patients. The result showed that from 3 samples had MIC 25%, and 4 samples 50%. MFC showed 1 sample in 12.5%, 3 samples in 100%, but 4 samples could still grow in 100% concentration with different number of colony forming units. As the control group, Candida albicans ATCC 10231 showed MIC in 25% and MFC in 75%. In conclusion, aloe vera plants seem to have promising role to cure oral candidiasis in HIV/AIDS patients because of its antifungal and immunomodulatory properties.

Currently, bone graft is recommended to improve and support the biological repair of bone defects properly. Bone graft was found to cause death in the donor area, long pain, infection, cosmetic deformity, hematoma, the amount of blood loss, injury or damage to the nervous in the donor area. Synthetic bone graft material was developed as a scaffold that serves to template the formation of bone. The ideal scaffold should be biodegradable, osteoconductive and osteoinductive. During there graft materials have not optimally provide the morphological, mechanical properties, biocompatibility and biodegradation, and osteoinductive-osteoinductive. Silica is proven to support and promote primary osteoblast growth, synthesis of matrix proteins, collagen type I, so that it can cause bone formation. Rice husk contains of silica is high enough. Because of abundant material and its potential in bone formation, needs to be done research on silica from rice husk in the manufacture of synthetic bone graft. The purpose of this study was to analyze the amorphous silica from waste rice husks as synthetic bone graft material (scaffold), especially against osteoblasts proliferation. Type of study was an experimental laboratory. This research was conducted by isolating the amorphous silica from rice husk. Primary osteoblast cultures derived from calvaria rats aged 2 days, growing in Alpha Modified Eagle Medium (Î±-MEM) (as negative control), Î±-MEM that in condition with 58S silica (as positive control group) and Î±-MEM condition with silica from rice husk (as treatment group). Osteoblast proliferation was observed with Quick Cell Proliferation Assay Kit for 7 and 14 days. The result showed that the rice husk silica was significantly (p <0.05) osteoinductive, osteoblast cultures demonstrated that its proliferation was higher in the groups that were implanted in the culture medium condition with 58S silica. In conclusion, rice husk amorphous silica is potentially osteoinductive scaffold for synthetic bone graft material.

Champhoroquinone is a photo-initiator of visible light composite resin (VLCR). It is light yellow fine powder form. Both of them help polymerization process of VLCR. The aim of the study was to know the ability of bonding agent and champhoroquinone to increase visible light composite resin hardness in flow readily. This study was laboratory experimental. The subjects were divided into 3 groups, they were champhoroquinone group (CPG), bonding group (BG), and control group (CG). Every group consisted of 24 specimens. VLCR paste was exposed under light of dental unit lamp for 2 minutes. After that, VLCR paste was added with bonding and champhoroquinone, and was mixed until homogen. Then, the mixed was taken into mould space (5 mm in diameter and 2 mm in thickness), was compressed and flatened, and was cured for 40 seconds. All samples were tested the hardness by Vikers Hardness Number (VHN). All data were analyzed by Kruskal Wallis Test and continued by Mann -Witney-U Test. The result showed that the mean of BG (56.96 VHN) was higher than CG (55.11 VHN) and CPG (51.19 VHN). The statistic test showed there was significant different between the group. In conclusion, the bonding agent can increase hardness of VLCR in flow readily and better than control and champhoroquinone group.

Empirically, societies have utilized neem plant to treat worm infection, scabies, malaria, candidal infection, and allergy. Several researches have indicated that consuming neem leaves could improve antibody production. Our previous research had demonstrated the existence of immunomodulatory component in neem leaves weighted 70 and 100 kDA. The aimed of study was to test the activity immunomodulatory components to Candida albicans. This research was an in vitro study with rats as experimental subject. The rats were divided into three treatment groups and one control group, which were labeled as KO (no treatment), KP1 (inoculated by C. albicans only), KP2 (inoculated by C. albicans and were given the 70 kDA immunomodulatory component), KP3 (inoculated by C. albicans and were given the 100 kDA immunomodulatory component). In day 21, preparations from ratsâ€™ tongue were done with immunohistochemistry staining and were analyzed for the activity of TNF-Î± macrophage phagocytosis and also for calculation of C. albicans colony from tongue swab. The result showed that there was no significant difference between the 70 and 100 kDA immunomodulatory components in increasing activity of TNF-Î± and macrophage phagocytosis and in decreasing the number of C. albicans colony. It was assumed that those components might actÃvate NF-ÎºB and AP-1 that play role in protein transcription, which stimulated gene expression like TNF-Î±, which played role in phagocytosis. In conclusiÃ³n, 70 dan 100 kDA immunomodulatory components increased the activity of TNF-Î± and macrophage phagocytosis and also decrease the number of C. albicans colony.

Streptococcus mutans is a major caries-causing bacteria, which can aggregate to form plaques. Nowadays, caries prevention approach in the cellular level can be done through molecular technology by using anti-bacterial, antibodies or addition of remineralization agent such as Casein Phospho Peptide-Amorphous Calcium Fluor Phosphate (CPP-ACFP) as an inhibitor of biofilm formation by Streptococcus mutans. The purpose of this study was to investigate the role of CPPACFP as an inhibitor to the growth of S. mutans, when used in low and moderate caries risk patient. The CPP-ACFP paste was applicated to patients for 60 days. Any caries inhibitory effects were evaluated as the difference of S.mutans count which was analyzed by S. mutans strip count (GC Corp) and colony count was performed with a bacterial culture. The result showed that there was no significant difference between before and after using CPP-ACFP in colony counting by S.mutans stripcount (GC Corp), pH, and buffer capacity from saliva.In conclusion, there was no effect after using CPP-ACFP since user didnâ€™t use it regularly. To expect better result in using CPP-ACFP preventive treatment, we should improve patientâ€™s compliance.
