<![CDATA[Background: Improvement in dentistry shows some progresses, due to patients awareness on the importance of dental care. Cervical lesion is the most common phenomenon which oftenly found 46.36% in man and 38.13% in woman. Cervical lesions need composite restoration for treatment to stop the process of tissue damage. The process of adhesion of composite restoration material to the structure of the tooth is not easily separated and it needs optimal function in the oral cavity. Application of dentin bonding agents to attach the composite is needed. Selection of HEMA-based bonding material and Hema free-based bonding material which have a different solvent in their composition, as applied to the dentin superficial and deep dentin, affect the results of debonding test. Debonding test is done to measure the adhesion strength of a bonding material. Purpose: The purpose of this study was to analyze differences in tensile bond strength of dentine bonding HEMA-based and HEMA-free based after application in superficial and deep dentine surfaces. Method: The tooth of the bovine was as samples. A superficial dentine sample was taken from 0.5-1 mm of dentino enamel junction and a deep dentine sample was taken from 0.5 mm culmination of pulp horn. Dentine surface area was equal to p x r2 = (3.14 x 22) = 12.56 mm2. Six samples of HEMA-based bonding was applied to the dentine superficial. Six samples of HEMAfree based bonding was applied to the superficial dentine. Six samples of HEMA-based bonding was applied to the deep dentine. Six samples of HEMA-free based bonding was applied to the deep dentine. Tensile strength was measured using an Autograph AG-10TE. Result: There were differences tensile bond strength of dentine bonding HEMA-based and HEMA-free based after the application on superficial (p=0.000) and deep dentine surfaces (p=0.000). Conclusion: There were differences tensile bond strength of dentine bonding HEMA-based and HEMA-free based after the application on superficial and deep dentine surfaces. The use of dentine bonding materials HEMA-free based were better than HEMA-based after application on different dentine depths.]]>

<![CDATA[Background: The high prevalence of early childhood caries still becomes a major health problem. It is because children prefer to consume sweet foods, which are also cariogenic. The oral mucosa is a mirror of general health or any systemic disease which usually shows visible symptoms in the oral cavity. Dental caries in children is often related to the socioeconomic characteristics of the parents. Some references suggest that there is a relationship between the socioeconomic status with the incidence of caries. Purpose: The purpose of this study was to examine the relationship of socioeconomic characteristics of the parents with the risk prediction of early childhood caries by using cariogram approach to the elementary school students in Wonosobo. Method: The research is an observational analytic study with cross-sectional approach survey method. The research sampling uses proportional random sampling with 201 respondents of fifth graders. The socioeconomic status is measured through questionnaires, while the risk prediction of early childhood caries is measured by using cariogram. The research data analysis uses Spearman rank. Result: The results of the study show that the socioeconomic characteristics of the respondents’ parents mostly belong in the middle category as many as 145 respondents (72.1%), lower category as many as 31 respondents (15.4%) and in the upper category as many as 25 respondents (12.4%). Prediction of the respondents avoiding early childhood caries is 55%, while the prediction of the respondents being risked of having early childhood caries is 45%. The results of data analysis show that the relationship between the socioeconomic characteristics of the respondents’ parents and the risk of having early childhood caries for the respondents is p<0.05. Conclusion: There is a relationship between the socioeconomic characteristics of the respondents’ parents with the early childhood caries, which shows that the higher the socioeconomic status of the parents, the lower the risk of the respondents from having early childhood caries.]]>

<![CDATA[Background: In deep dentinal caries cases, bacteria mostly found are Lactobacillus acidophilus classified as gram positive bacteria and as facultative aerobes producing glucosyltransferase (GTF) enzyme. GTF enzyme can alter sucrose into glucans. Glucan is sticky and insoluble in water. As a result, GTF enzyme can facilitate plaque formation and microorganism colonization on tooth surface. In addition, Lactobacillus acidophilus also can form acid leading to demineralization of organic and inorganic materials, resulting in dental caries. Multidrug-resistant phenomena, on the other hand, have led to the use of natural resources, one of which is propolis as an antimicrobial material and as a new anti-infective therapeutic strategy. Propolis is a resinous substances collected by worker bees (Apismellifera) from barks and leaves of plants. Propolis has a complex chemical composition and biological properties, such as antibacterial, antiviral, antifungal, anti-inflammatory, and antitumor. Purpose: This research aimed to reveal anti-glucan effects of propolis ethanol extract generated from honey bee, Apis mellifera spp on Lactobacillus acidophilus bacteria. Method: Before antiglucan test was conducted, glucan-formation test was performed on Lactobacillus acidophilus bacteria using SDSpage. Meanwhile, anti-glucan adhesion test on Lactobacillus acidophilus bacteria was carried by culturing the bacteria at 37ºC temperature in a jar with 10% CO2. Test tubes were placed at an angle of 30º for 18 hours to review the attachment of bacteria at the glass surfaces. After the incubation, the culture of bacteria was vibrated using a mixer vortex for a few minutes, and then cultured in solid MRS A media. Bacteria grown were measured by using colony counter. Result: The ethanol extract of propolis with a concentration of 1.56% was the lowest concentration inhibiting the attachment of glucan to Lactobacillus acidophilus bacteria. Conclusion: The ethanol extract of propolis with a concentration of 1.56% can be used as an anti-glucan material for Lactobacillus acidophilus bacteria.]]>

<![CDATA[Background: Fixed orthodontic appliance patients have a high risk to increasing plaque accumulation in tooth surface due to the presence of fixed appliance components. Using mouthwash with antibacterial agent from herbal material can control dental plaque accumulation. Bay leaf (BL) contains active compounds such as essential oil, tannin and flavonoid that have been known as an antibacterial agent. Purpose: The purpose of this study was to determine the effect of rinsing with 60% of BL aqueous decoction to the accumulation of dental plaque in fixed orthodontic appliance patients. Method: This research was an experimental clinical research with pretest and post-test control group design conducted on 20 subjects with age ranged between 18-25 years old. All subjects were undergoing the last stage (finishing) of fixed active orthodontic treatment. The subjects were instructed to rinse with 60% of BL aqueous decoction and 0.2% chlorhexidine as a control. Wash out period that needed between rinsing with 60% of BL aqueous decoction and rinsing with 0.2% chlorhexidine was 7 days. Each mouthwash used routinely for 7 days with same duration and intensity. Plaque scoring was measured before and after each treatment using Orthodontic Plaque Index (OPI). Result: One-way Anova test showed that there was a significant difference in the plaque index before and after treatment between the group of rinsing with 60% of BL aqueous decoction and group of rinsing with chlorhexidine (p<0.05). Conclusion: Rinsing with 60% BL aqueous decoction can decrease the accumulation of dental plaque in fixed orthodontic appliance patients.]]>

<![CDATA[Background: The most common fungal infection found in oral cavity is oral candidiasis, largely caused by Candida species, particularly Candida albicans (C. albicans). Candida infection can get worse since it is difficult to be treated and resistant with antifungal drugs. Therefore, new drugs and compounds as well as alternative therapies involving natural sources that have antifungal activities have continually been developed. Limonene, β-pinene, and ɣ-terpinene contained in Citrus limon essential oil have been known to have quite good antifungal activities against C. albicans. Purpose: This research aimed to examine and analyze the effects of Citrus limon essential oil on cytomorphometric changes of C. albicans. Method: The research used post test only control group design. Based on the results of the pre-elementary research on antifungal activities of Citrus limon essential oil against C. albicans, Citrus limon essential oil used in this research was on concentrations of 1.56%, 1.37%, 1.17%, 0.98%, and 0.78%. Citrus limon essential oil by C. albicans inoculum and incubated for 24 hours and 48 hours. After the incubation, those C. albicans cells were fixed, dried, and then observed using a scanning electron microscopy. Result: The most effective concentrations of Citrus limon essential oil triggering cytomorphometric changes of Candida albicans were at 1.37% and 1.56% with the incubation period of 48 hours. Conclusion: C. albicans can undergo necrosis process through cytomorphometric changes after the administration of Citrus limon essential oil at concentrations of 1.56% and 1.37% with the incubation period of 48 hours.]]>

<![CDATA[Background: Tooth loss can be caused by trauma, caries, and periodontal disease. It then can trigger an emotional impact on each individual, such as having a lack of confidence, feeling ashamed of the appearance, and trying to hide the missing teeth. As a result, people experiencing tooth loss want to put or replace their missing teeth with artificial ones. Unfortunately, many of them prefer to visit non-professional dentists rather than professional ones providing the same services because of both internal and external factors. Purpose: This research aimed to analyze factors affecting the public interest in Losari District of Brebes Regency in 2016 to install dentures in non-professional dentists. Method: This research focused on a correlation of cost, time, need, access, and competence with denture-making care interest using survey method. Sampling was conducted with purposive sampling technique. The number of samples was thirty-six people. Result: There was a significant correlation between public interest in installing dentures at non-professional dentists and cost factor (a p value of 0.010, <a 0.05). Similarly, there was a significant correlation between public interest in installing dentures at non-professional dentists and time factor (a p value of 0.000, <a 0.05). There were significant correlations between the public interest in installing dentures at non-professional dentists and need (a p value of 0.004, <a 0.05), as well as between public interest in installing dentures at non-professional dentists and access factor (a p value of 0.000 <a 0.05). Nevertheless, there was no correlation between public interest in installing dentures at non-professional dentists and competence factor (a p value of 0.482> a 0.05). Conclusion: It can be concluded that there is a correlation between cost, time, need, and access with the public interest in installing dentures at non-professional dentists. Community competence has no correlation with public interest in installing dentures at non-professional dentists.]]>

<![CDATA[Background: Exposure of metals among dental technicians that come from the working environment can lead to the formation reactive oxygen species (ROS). ROS can cause mutations in the p53 gene (p53). The mutation is transversion mutation GuanineThymine. p53 mutations can lead to low expression of the wild-type p53 protein (p53). Wild-type p53 involved in many biological processes such as regulation of genes involved in cell cycle, cell growth after DNA damage, and apoptosis. However, exposure to metals among dental technicians can be prevented through the use of personal protective equipment (PPE) during work. Purpose: The purpose of this study was to analyze the correlation between the use of personal protective equipment to wild-type p53 protein levels among dental technicians in Surabaya. Method: This study was observational analytic with cross sectional approach. 40 samples were taken by random sampling. Data were retrieved through interviews and observations. Wild-type p53 was analyzed from saliva with indirect ELISA method. Analysis of data used Kolmogorov Smirnov normality test and a Pearson correlation test. Value significance was p<0.05 (95% confidence level). Result: There was a significant association between the use of personal protective equipment with wild-type p53 levels with p=0.002 Conclusion: The use PPE properly is positively correlated with the wild-type p53 protein levels of dental technicians in Surabaya.]]>

<![CDATA[Background: The main oral health problem in Indonesia is the high number of tooth decay. Tooth extraction is the treatment often received by patients who experience tooth decay and the wound caused by alveolar bone resorption. Bark of Mangifera casturi has been studied and proven to contain secondary metabolite which has the ability to increase osteoblast’s activity and suppress osteoclast’s activity. Purpose: The purpose of this study was to analyze interleukin-1 beta (IL-1β) and bone morphogenic protein-2 (BMP-2) activities during bone remodeling after Mangifera casturi’s bark extract treatment. Method: This study was laboratory experimental research with randomized post-test only control group design. The Mangifera casturi bark was extracted using 96% ethanol maceration and n-hexane fractionation. This study used 40 male Wistar rats which are divided into 4 groups and the tooth extraction was performed on the rats’ right mandible incisive tooth. The four groups consisted of 6.35%, 12.7%, 25.4% extract treatment group, and a control group. Wistar’s mandibles were decapitated on the 7th and 14th day after extraction. Antibody staining on preparations for the examination of IL-1β and BMP-2 expressions was done using immunohistochemistry. Result: There was a significant difference of IL-1β and BMP-2 expressions in 6,35%, 12,7%, and 25,4% treatment groups compared to control group with p<0.05. Conclusion: Mangifera casturi’s bark extract was able to suppress the IL-1β expression and increase the BMP-2 expression during bone remodeling after tooth extraction.]]>
