Background: Candidiasis is one of oral infectious disease caused by Candida albicans.The role of C. albicans as pathogen opportunistic in oral infection can affected by immune system. Phagocytosis has contributed in immune system against C. albicans infection, which is the role of monocytes. Grapthophyllum L. Griff has been proved to increase macrophage’s phagocytic activity, but the effect of violet leaves ethanol extract (EEDU) to increase monocyte’s phagocytic activity on C. albicans is unknown. Objectives: To determine the effect of violet leaves extract on monocyte’s phagocytic activity on C. albicans. Methods: This research was acted in vitro on human monocyte cell culture. There was 5 groups: negative control group, positive control group (incubated in Isoprinosine) and treatment groups was incubated in EEDU 2,5%, 5%, 10%. The percentage of activated monocytes was counted. Result: The result showed that incubation of EEDU 2,5%, 5% and 10% could increase monocyte’s phagocytic activity significantly (p<0,05) compared to control groups. The number of monocyte’s phagocytosis on C. albicans incubated with EEDU 2,5%, 5% and 10% is 65%, 60,5%, and 58,75%. The optimal concentration of EEDU to increase monocyte’s phagocytic activity was 2,5%. Conclusion: The study showed that EEDU can increase monocyte’s phagocytic activity on C. albicans.

Background: Porphyromonas gingivalis bacteria are found in dental plaques and have the ability to form biofilms. Biofilms are collections of bacterial cells, which are tightly attached to a surface covered by an extracellular polymer matrix released by the bacteria. Periodontitis therapy generally uses tetracycline antibiotics which if used long-term can cause resistance. Chitosan Rajungan crab extract (Portunus pelagicus) has antimicrobial potential which can be used as an alternative therapy. Objective: To determine the antibacterial power of Rajungan crab chitosan extract (Portunus pelagicus) in various concentrations of Porphyromonas gingivalis bacterial biofilms. Method: This research was true experimental laboratorist. This study used Rajungan crab chitosan extract (Portunus pelagicus) to Porphyromonas gingivalis biofilm tested by the test method biofilm. Divided into 5 groups, where each group consisted of 4 samples. The control group consisted of: K- (negative control group), K + (positive control group / tetracycline group), and 3 treatment groups, namely P1 (0.25% Rajungan crab chitosan), P2 (0.5% Rajungan crab chitosan) , P3 (1% Rajungan crab chitosan). Antibacterial power was determined by the value of Optical density in the ELISA Reader. Data analysis using One Way ANOVA followed by LSD test. Result: There were significant differences (p <0.05) seen from the percentage of biofilm inhibition in the negative control group for all groups, the positive control group for the crab crab chitosan extract concentrations of 0.25% and 0.5%. Conclusion: The chitosan crab chitosan extract (Portunus pelagicus) with 1% concentration has the greatest antibacterial effect on the Porphyromonas gingivalis biofilm

Background: Oral candidiasis generally caused by Candida albicans with prevalence of 30-50%. C. Albicans proliferation in the oral cavity was canducted by decreasing immune system of the host. Lymphocytes activation in immune system happened when there is a contact between host cell with cell wall of C. albicans as a result of C. albicans antigen. One of therapy to suppress the Candida infection sistemically is by giving hyperbaric oxygen therapy. Purpose: To determine the effects of giving hyperbaric oxygen therapy to the amount of lymphocytes in oral candidiasis immunosuppressed models. Methods: This research was post test only control group design. We used 12 wistar rats which were divided into 3 groups(n=4/3): K-(normal/ healthy wistar rats), K+(oral candidiasis immunosuppressed wistar rats), P1(oral candidiasis immunosuppressed wistar rats which were given hyperbaric oxygen therapy 5 days). K+ and P1 groups were immunosuppressed by giving dexamethasone 0,5mg/day/rat orally for 14 days, added with tetrasiklin 1 mg/day/rat. On the 3rd day immunosuppression, the rats were inducted with C.albicans smeared in the dorsum linguae once every two days for 12 days. Results: The data were analyzed with one way Anova test and showed significant difference among groups (p<0,05). To show the difference between each groups we used LSD test and showed significant difference (p<0,05) between K+ compared with P1, and K+ compared with K-. Conclusion: Hyperbaric oxygen therapy gives effect to the amount of lymphocytes in oral candidiasis immunosuppressed models.

Background : The denture base made of acrylic resin has a porosity and water absorbtion characteristic to cause the deposition of food waste, that problem was known to cause a growth of Candida albicans microorganisms. This problem can be solved by providing a coating (Surface coating) made of natural polymer (cellulose acrtate) of sea sea grass (Enhalus acoroides) mixed with hydrocoloid material so as to provide protection properties. Such protective properties can inhibit the bonding between the residual monomer results of acrylic resins and microorganisms. Objective : To analyze and compare the number of Candida albicans colonies on the acrylic resin plate that has surface coating and no surface coating. Method : Using post test only group design, using 12 samples divided into 2 groups. Group 1 is the control group (Heat cured acrylic plate contaminated with Candida albicans). Group 2 : Treatment group (Heat cured acrylic plate with surface coating made from sea grass Enhalus acoroides then contaminated with Cndida albicans). Calculating the number of colonies from Candida albicans was done by calculating the turbidity of SDB media (Saboraud Dextrose Broth) using UV-VIS Specrofotometer with 560 λ wave. Data analysis using an Independent T-Test. Results : Acrylic resin plates with surface coating showed significant differences in the number of Candida albicans colonies. The average results in the control group obtained an average number of colonies of 1,58 CFU/ml, while in the treatment group as much as 1,42 CFU/ml. Conclusion : The results show that surface coating can decrease the amount of Candida albicans colonies because it can close the microporosity, prevent a water absorption, and prevent the formation of the pellicle.

Background: Nursing bottle carries is a problematic condition in children. On one side, parents try to supply enough nutrition to their children, though on the other side this night-time bottle feeding habit might cause negative effect on the childrens dental health. Esthetic dental treatment on children have improved greatly over the past few years, as parents expect an almost-complete restoration of their child’s dental condition. The alternatives for pediatrics esthetic dental restoration may depend on the cooperativeness and habit of the child themselves, while also taking the child’s development into consideration. Aim: to report evaluation of aesthetic restoration on primary teeth. Case: A 4 year-old female child was presented by her parents, with damaged four anterior teeth, which made her uncomfortable especially on feeding due to the sharp edges. From history taking we found a night-time bottle-feeding habit, which usually occurred until patient was asleep. Case Management: restoration of the four primary incisive teeth was performed using a resin composite crown. Outcome of the treatment was evaluated until the primary teeth exfoliateand permanent teeth arise. Conclusion: cooperation between patient, parents, and dentist is important in the dental restorative treatment on paediatric patient. Moreover, a good communication with parents is encouraged, especially on follow-up schedule, treatment cost, success rate and possibility of treatment failure is also encouraged. Staged evaluation is needed due to the natural substitution of the primary teeth by permanent teeth, besides the development process of the jaws.Keywords: Nursing bottle caries, esthetic restoration, growthanddevelopmentCorrespondence: Annisa Listya Paramita, drg., Sp.KGA.

Background: Dental caries is a major oral health problem which is most commonly found in Indonesia. One of the main factors in role of causing dental caries is Streptococcus mutans which is the primary target of the prevention of caries. Leaf extract of Sonneratia alba hasbeen proven to have an antimicrobial effect towards Streptococcus mutans, but its cytotoxic activity on normal cells is still unknown. The initial cell viability in this study was conducted using cell line BHK-21. Purpose: The aim of this study is to determine the cell viability offibroblast cells line BHK-21 by given Sonneratia alba’s leaf extract. Materials and Methods: The experiment was conducted using post test only control group design. BHK-21 fibroblast cell culture on 96 wells were divided into cell control group (n=9), media control group (n=9) and test groups (n=9). The test groups were given various concentration of Sonneratia alba’s leaf extract, they were: 5%; 10%; and 20%. The cell cultures were incubated for 24 hours before and after treatment using Sonneratia alba’s leaf extract. After dripping MTT into the microplates, OD were read using ELISA reader and the viability were counted. The data that was acquired from the viability calculation was statistically analyzed using One Way ANOVA and LSD test. Results: Data showed the increase of viability cell in all the test groups. The highest viability cell showed by the test group with 10% concentration of Sonneratia alba (153,7122%±7,42458), and the lowest found in the test group with 20% concentration of leaf extract (141,4682%±7,48752). Conclusion: In this experiment, the leaf extract of Sonneratia alba proved to be nontoxic on fibroblast cells line BHK-21, the extract increased the viability and also caused proliferation of fibroblast cells.
