Background: Ubiquinone is one of food supplement which is known have positive effect in wound healing. However the study to evaluate the possible role of ubiquinone in bone healing in autogenous bone grafting after mandibular resection has not been studied. An in vitro study is required to evaluate whether ubiquinone or coenzyme Q-10 (CoQ10) has a positive effect on osteogenesis. Viability test of CoQ10 and a model of osteogenic-induced and hypoxic-condition mesenchymal stem cell culture were established to support the study. Purpose: The study was made to evaluate the role of ubiquinone in osteogenesis by analyzing the toxicity effect and the optimal dose of CoQ10 that might interfere in bone marrow derived mesenchymal stem cell (BM-MSC) that was dose in cell culture medium. The BM-MSC culture under hypoxia condition were also observed. Method: The toxicity and the optimum viability concentration of ubiquinone were observed using MTT assay. The osteogenic differentiation under hypoxic condition was done on BM-MSC in osteogenic medium that composed of ascorbic acid, glycerolphosphate and dexamethasone in hypoxia chamber for 21 days. Osteogenic differentiation and cellular hypoxia features were tested with immunocytochemical staining using anti-Runx2 and anti-HIF1α monoclonal antibody, respectively. Result: The maximum density value of 1.826 was found in the group of ubiquinone concentration of 75μM/ml, increasing of in concentration of ubiquinone resulted with the decrease ofoptical density of CoQ10. Statistic analysis using Anova showed with no significant difference among groups with various concentration. Immunocytochemical staining showed that Runx2 expression in 3% hypoxia group (p<0.05). Conclusion:Ubiquinone was found non toxic in its optimum dose of 75μM/ml, showed by optimum result in the expression ofRunx2 and HIF1α further study is necessary to evaluate the angiogenic and osteogenic effect ofubiquione.

Background: Oral candidiasis is an opportunistic infections due to Candida albicans that often found in people with HIV/AIDS. Anti-fungi, polyne and azole, are used in the treatment of oral candidiasis, but often cause persistence and recurrence. Citrus Limon peel contains terpenoids capable of inhibiting the synthesis of ergosterol, a component of the fungal cell wall that helps to maintain cell membrane permeability. Essential oil derived from citrus limon peel, thus, is expected to inhibit the growth of Candida albicans. Purpose: This research was aimed to know how essential oil derived from citrus Limon peel can inhibit the growth of Candida albicans. Method: This research was a laboratory experimental research carried out in three phases. First, essential oil was made with cold pressing method, and then the concentration of 100% was diluted to 50%, 12.5%, 6.25%, 3.125%, 1.56% and 0.78%. A test was conducted on the culture of Candida albicans in Sabouraud broth, accompanied by control (+) and (-). Second, the dilution of essential oil was conducted to alter the concentration with inhibitory power, from the strongest one to the weakest one, and then it was tested on the culture of Candida albicans. Third, spreading was carried out from liquid culture to agar media in order to measure the number of colonies. Result: Candida albicans did not grow on media with 100% essential oil treatment, but it grew on media with 50% essential oil treatment. In the second phase, dilution of 100%, 90%, 80%, 70%, 60% and 50% was conducted. The growth of Candida albicans was found on the treatment media of 60% and 50%. On the agar media, the growth occurred in the cultured medium treated with 70%. Conclusion: The minimum inhibitory power of essential oil derived from citrus Limon peel against Candida albicans was in the concentration of 80%. Essential oil derived from citrus Limon peel has antifungal effect and potential as a therapeutic agent for oral candidiasis.

Background: Severe early childhood caries (S-ECC) and decay exfoliation filling teeth (def-t) >6 is a destructive disease that afflicts teeth, including maxillary anterior teeth. In Indonesia, the prevalence of this disease is still high, for instance in Semarang 2007, the rate reached 90.5% in urban areas and 95.9% in rural areas for early childhood caries which is caused by Streptococcus mutans (S. mutans). Neutrophils are effector cells of innate immunity which become the main component of the very first line of defense against microbes. Purpose: This study analyzed the effect caused by the change of CD63 expression on the surface of salivary neutrophils and the increased level of S. mutans in S-ECC. Method: This study employs observational analytic and cross sectional approach by using T test analysis technique for forty cases of early childhood that had been divided into two groups, first group of twenty children positively diagnosed as S-ECC and second group of twenty children negatively diagnosed as the control group. The sample’s result of gargling with 1.5% NaCl was used for neutrophils isolation and analysis function of salivary neutrophils phagocytosis by using flow cytometry test, while the sample of saliva was used to isolate S. mutans and calculate the level of S. mutans. Result: The expression of CD63+ salivary neutrophils in S-ECC was lower (2.32% ± 0.57) than in caries-free (2.67% ± 0.46), while the level of S. mutans showed that the level was not higher than in S-ECC (9.78 ± 2.22)x105 CFU/ml compared to in caries-free (5.13 ± 1.86)x105 CFU/ml. Conclusion: The low expression of CD63 in salivary neutrophils can lead to the increased level of S. mutans in S-ECC.

Background: Wound healing involves cellular, molecular, physiological, and biochemical processes as responses to tissue damage. For instance, when a failure during tooth extraction occurs, radiographic examination, X-rays, is required. X-rays as an enforcer diagnosis can damage DNA chain, resulting in cell death and inhibition of wound healing process. Purpose: This research aims to analyze fibroblasts cell number and fibroblast growth factor-2 (FGF-2) expressions during wound healing process after tooth extraction as a result of X-ray irradiation. Methods: There were three research groups, each consisting of ten rats. Incisor tooth extraction was performed on the left lower jaw, and then X-ray examination was conducted at certain irradiation doses, namely 0 mSv, 0.08 mSv, and 0.16 mSv. Those animals were sacrificed on day 3, and on day 7 after the extraction, histopathology and immunohistochemistry examinations were conducted to determine fibroblast cell number and FGF-2 expressions. Data obtained were then analyzed by oneway ANOVA and Tukey HSD tests. Results: The number of fibroblasts decreased significantly in the group with the irradiation dose of 0.16 mSv applied on day 7 after the extraction (p <0.05). Similarly, the number of FGF-2 expressions decreased significantly in the group with the irradiation dose of 0.16 mSv applied on days 3 and 7 after the extraction (p <0.05). Conclusion: X-ray irradiation at a dose of 0.16 mSv can inhibit the healing process of tooth extraction wound due to the decreasing of fibroblasts cell number and FGF-2 expressions.

Hyperglycemia has a correlation with the occurrence of periodontal disease. Curcuma zedoaria oil is known to decrease concentration of serum glucose. Purpose: This study was aimed to determine the effects of Curcuma zedoaria oil on high blood sugar level and gingivitis in rats. Method: This study used twenty-five male Wistar rats, divided into two groups, namely the treatment group and the control group. In the treatment group, fifteen rats were divided into three subgroups (each of which was induced with 10 μl/ml, 30 μl/ml and 50 μl/ml of Curcuma zedoaria oil). The control group was consisted often rats, divided into two subgroups, as the positive control group (induced with 10 mg/kg of Glibenclamide) and the negative control group (induced with propylene glycol). Streptozotocin (STZ) (Naclai tesque, Kyoto Japan) with a dose of 40 mg/kg was used to create hyperglycemia condition in those rats. Gingivitis was then made by using silk ligature in those hyperglycemia rats. Silk ligature was twisted at the margin of gingiva anterior mandibular incisors for seven days. After the rats had gingivitis, Curcuma zedoaria oil, glibenclamide and propylene glycol were orally administered for seven days. Their gingivitis condition was observed, and their blood sugar level was measured before and after the induction of STZ and during the treatment. The data obtained were analyzed by using Manova. Result: There were significant differences of blood sugar levels between the treatment group before and after the administration of Curcuma zedoaria oil and the positive control group (p<0.05). Healthy gingiva was then found in the treatment group and the positive control group. Conclusion: Curcuma zedoaria oil can decrease blood sugar level and gingivitis.

Background: Root canal treatment consists of preparation, sterilization, and obturation. During root canal preparation, debris is smeared over the dentinal surface forming a smear layer. Smear layer will reduce the attachment of root canal filling materials. Organic material in smear layer can be substrated for microorganism. Preparation of root canal should be followed by irrigation. NaOCl is common irrigation solution in endodontics. It has been very effective for their disinfecting and tissue-dissolving properties, but it is incapable of removing the smear layer. On the other hand, saponin of mangosteen peel extract has an ability as a surfactant to lower the surface tension, and it can dissolve debris containing of anorganic and organic materials. Purpose: This study aims to know the differences between 2.5% NaOCl and 0.002% saponin of mangosteen peel extract in removing the debris in the root canal after the preparation procedure. Method: Three groups of teeth (7 teeth in each) were instrumented with K-file and irrigated as follow: group 1 (control) with aquadest; group 2 with 2.5% NaOCl; and group 3 with 0.002% saponin of mangosteen peel extract. Furthermore, those teeth were split horizontally and longitudinally 4mm above the apical. The apical third of root canal walls was observed by a scanning electron microscope (SEM). Result: There were significant differences between each group (p<0.05). Median value of the group 3 was score 1 considered as the smallest value. It indicates that Group 3 with 0.002% saponin of mangosteen peel extract was the cleanest group. Conclusion:It can be concluded that 0.002% saponin of mangosteen peel extract can clean the smear layer of the root canal better than 2.5% NaOCl.
