Background: A pembarong performer is a reog dancer who bites on a piece of wood inserted into his/her mouth in order to support a 60 kg Barongan or Dadak Merak mask. The teeth supporting this large and heavy mask are directly affected, as the strong bite force exerted during a dance could affect their vertical and sagital facial dimensions. Purpose: This study aimed to examine the influence of the bite force of pembarong performers due to their vertical and sagital facial dimensions. Methods: The study reported here involved fifteen pembarong performers and thirteen individuals with normal occlusion (with specific criteria). The bite force of these subjects was measured with a dental prescale sensor during its centric occlusion. A cephalometric variation measurement was subsequently performed on all subjects with its effects on their vertical and sagital facial dimensions being measured. Results: The bite force value of the pembarong performers was 394.3816 ± 7.68787 Newtons, while the normal occlusion was 371.7784 ± 4.77791 Newtons. There was no correlation between the bite force and the facial sagital dimension of these subjects. However, a significant correlation did exist between bite force and lower facial height/total facial height (LFH/TFH) ratio (p = 0.013). Conversely, no significant correlation between bite force and posterior facial height/total facial height (PFH/TFH) ratio (p = 0.785) was detected. There was an inverse correlation between bite force and LFH/TFH ratio (r = -.464). Conclusion: Bite force is directly related to the decrease in LFH/TFH ratio. Occlusal pressure exerted by the posterior teeth on the alveolar bone may increase bone density at the endosteal surface of cortical bone.

Background: Bone damage can be caused by various factors with treatment usually involving graft materials being applied to the defective area. Moreover, in the bone defect healing process, blood vessels are also considered to be an important energy source for cell proliferation. One of the angiogenic factors playing an important role in blood vessel formation is basic fibroblast growth factor (bFGF). Furthermore, synthesized hydroxyapatite derived from Anadara granosa (AG) shells constitutes one of the potential materials for use in bone graft. The gold sea cucumber genus Stichopus hermanni (SH) possesses the ability to stimulate endothelial progenitor cells inducing bFGF. Purpose: This study aims to investigate the effects of AG shells and SH on bFGF expressions and blood vessel counts within the bone healing process. Methods: Twenty four male Wistar rats were divided into three groups, namely: a control group (C), a treatment group was administered with blood cockle shell (AG), and a treatment group with blood cockle shell and golden sea cucumber (AG+SH). Defects were made on their femurs measuring half the diameter of a circular, no. 018. bur These rats were subsequently sacrificed on day 7 after surgery. The expressions of bFGF were measured by means of IHC technique, while the number of blood vessels was quantified using HE technique. The resulting data was subjected to statistical analysis using an Anova test followed by an LSD test (p < 0.05). Results: The one-way Anova test results combined with those of an LSD test showed there to be significant differences in bFGF expressions and blood vessel counts between the control group (K) and the treatment group (AG) as well as between the treatment group (AG) and the treatment group (AG+SH). Conclusions: A combination of Anadara granosa shell and Stichopus hermanni can increase the expression of bFGF and the number of blood vessels on day 7 during the bone healing process in Wistar rats.

Background: The use of fiber post has become commonplace among dental practitioners due to its several advantages. In accordance with the intended use of post which provides retention for coronal restoration, a cement is used that can provide high quality adhesion. Conventional resin cement has long been adopted as a cementation material for consumer fiber post. However, allowing attachment fiber post failure due to errors in the cementing procedure leads to complications. Purpose: This study aimed to compare the adhesion strength of zinc phosphate cement and self-adhesive resin cement as fiber post cementation material. Both consumer cements were easy to use and cheap. Methods: The samples used numbered up to 20 and were divided into two groups. group 1 used zinc phosphate cement, while group 2 used self-adhesive resin cement. Results: The value of the average adhesion strength of group 1 (zinc phosphate) was 82.65 N, whereas that of group 2 (self-adhesive resin) was 402.81 N. Conclusion: This study concluded that the adhesive strength of self-adhesive resin cement as fiber post cementation material was higher than that of zinc phosphate cement.

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.

Background: A smile constitutes a form of measurement as to whether or not an orthodontic treatment has proved successful. A smile is said to be ideal if a balance exists between the shape of the face and teeth. One benchmark used to assess the quality of an ideal smile is that of buccal corridors. These are formed of the black space between the lateral edge of maxillary posterior teeth and the corner of the lip which appears during the action of smiling. Evaluating the contrasting perceptions of male and female smiles based on buccal corridor aspects is considered important to identifying the specific qualities an ideal smile. Purpose: The purpose of this study was to determine the difference between the perceptions of an ideal smile held by Indonesian dental students of both genders based on buccal corridors. Methods: A total of 36 dental students, equally divided between male and female students and ranging in age from 18-21 years old, were enrolled in this study. The smiles of all subjects were photographed from the front for later assessment by the subjects themselves. Assessment was undertaken twice, with a two-week interval between the first and second, by comparing subjects’ photographs with reference pictures of buccal corridors. Data gathered were analyzed by using kappa-statistic and U-Mann Whitney. Results: The results indicated that all the subjects showed a good level of coincidence in their analysis (κ=0.76). Statistical analysis showed that the score of 0.123 (p>0.05) was shown in U-Mann Whitney. Conclusion: Indonesian male and female dental students have the same perception of an aesthetic smile with regard to its buccal corridor.

Background: Denture adhesive is widely used in elderly people who wear complete dentures. Chinese herbal medicine has long been used for the treatment of oral disease. The addition of herbal medicine to denture adhesive might be used to develop an adhesive which is effective for xerostomia patients. Purpose: The purpose of this study was to evaluate physical properties and cytototoxicity of herbal medicine components in denture adhesive. Methods: This study used a combination of 35wt% PVM-MA, 20wt% CMC, 40wt% white petrolatum and 5wt% liquid paraffin as base materials. Three kinds of herbal medicine components: Maimendong (Ophiopogon), Fuling (Hoelen) and Dongkuizi (Cluster mallow seed) were added to base materials of 1wt%, 5wt% and 10wt%. The initial viscosity was measured using a controlled-stress rheometer (AR-G2). The adhesive strength was quantified according to ISO-10873 recommended procedures. All data was analyzed independently by one-way Anova combined with a Turkey’s multiple comparison test at a 5% level of significance. Results: Significant differences were observed between materials in initial viscosity (p < 0.05). Specifically, samples containing 5wt% and 10wt% of Maimendong (Ophiopogon) showed higher values compared with the control samples. The larger the amounts of herbal medicine components, the greater the changes in the adhesive strength of denture adhesives over time. The denture adhesives containing herbal medicine components do not have a cytotoxic effect and are safe for use in actual clinical practice. Conclusion: The study showed that the addition of herbal medicine components does not affect physical properties (i.e. initial viscosity and adhesive strength) of denture adhesive and cytotoxicity in fibroblast cells.

Background: Cigarette smoking is a public health issue that may influence the physical properties of dental composites. Surface roughness is one of the physical properties of restorative materials potentially influencing their success. The use of nanofilled and nanohybrid composites in dentistry has increased substantially over the past few years. Purpose: The purpose of this study was to evaluate the surface roughness of nanofilled and nanohybrid composite resins exposed to kretek cigarette smoke. Methods: Twelve cylindrical specimens of each material were prepared and divided into two groups (n=6). In the control groups, the specimens were immersed in distilled water for 24 hours at 37°C, with the water being renewed daily. For the experimental groups, the specimens were exposed to kretek cigarette smoke on a daily basis, then washed and soaked in distilled water at 37°C. After 21 days, the specimens were measured using a Surface Roughness Tester and the data was then statistically analyzed. Results: An Independent-T Test revealed that there were statistically significant differences in the surface roughness between the control and experimental groups of both nanofilled and nanohybrid composites, as well as between the nanofilled experimental group and the nanohybrid experimental group. Conclusion: Exposure to kretek cigarette smoke can increase the surface roughness of nanohybrid composites to a significantly greater extent than nanofilled composites.
