Introduction: Porcelain must have sufficient flexural strength to withstand mastication forces. The flexural strength of porcelain can be influenced by the maturity level of porcelain related to the temperature and sintering time. The purpose of this study was to compare the flexural strength of Indonesian natural sand self-synthesised porcelain with different sintering temperatures. Methods: Self-synthesised porcelain powder, with the composition of 65% Pangaribuan felspar, 25% Belitung silica, 5% Sukabumi kaolin, and 5% potassium salt, were condensed into 10 samples with the size of 7cm x 2cm x 0.4cm. A total of 5 samples were each burned at the temperature of 1150°C and 1200°C. Flexural strength test was performed using the Universal Testing Machine (Netzsch™) with the lowest load of 7.5 kg, and the data obtained was calculated using the bending strength formula. Result: The average flexural strength of self-synthesised porcelain at the sintering temperature of 1150°C was 26.678 MPa, while at the temperature of 1200°C was 39.038 MPa. Conclusion: This study concluded that Indonesian natural sand self-synthesised porcelain had a lower flexural strength at the sintering temperature of 1150°C than at the temperature of 1200°C.Keywords: Flexural strength, self-synthesised porcelain, sintering temperature.

Introduction: Denture cleanser must be able to remove bacterial plaque layers, eliminate food debris, with non-toxic properties. Denture cleansing was performed by immersing the denture into a solution of H2O2. Continuous denture wear can lead to plaque accumulation of Candida albicans colonies thus causes denture stomatitis. There was a slight dimensional stability difference of the self-cured acrylic base compared to the heat-cured after immersion in water. This study was aimed to analyse the effect of denture cleansing solution (H2O2) on the water solubility of self-cured acrylic resin. Methods: Twenty-four specimens of self-cured acrylic resin sized 15 x 20 x 2 mm, were divided into the control group (n = 12) and the treatment group (n = 12). All specimens were then immersed in the aquadest (control group) and H202(treatment group) for 6, 8, and 10 hours consecutively. Result: The average water solubility of self-cured acrylic resin soaked in H2O2 solution at 6 hours was 0.0007 µg/mm3; at 8 hours was 0.0011 µg/mm3; and at 10 hours was 0.0013 µg/mm3. The average water solubility of self-cured acrylic resin soaked in aquadest solution at 6 hours was 0.0013 µg/mm3; at 8 hours was 0.0080 µg/mm3; and at 10 hours was 0.0125 µg/mm3. Conclusion: The water solubility of the self-cured acrylic resin immersed in the H2O2 solution for 6, 8, and 10 hours was still below the ISO standard.Keywords: Self-cured acrylic resin, H2O2, immersion time, water solubility.

Introduction: Streptococcus sanguis is an initial cause of dental plaque formation which is the initial cause of caries. One of the preventive treatments can be done by using the mouthwash containing antibacterial substances. Along time, natural remedies are proven to be having more antibacterial properties. Ant-plant (Myrmecodia pendens Merr. & Perry) tubers are types of epiphytic plant that grows in many parts of Papua, with many health benefits, and are known to contain flavonoids, tannins, and tocopherols. This study was aimed to determine the antibacterial activity of ethyl acetate fraction from methanolic extracts of ant-plant tubers on the growth of Streptococcus sanguis ATCC 10566. Methods: The ant-plant tubers were extracted with soxhletation method using the methanol solvent. The fractionation was then performed using ethyl acetate to obtain the ethyl acetate fraction. Result: The phytochemical test showed that the ethyl acetate fraction of the ant-plant contained phenolics, tannins, flavonoids, and terpenoids. The bacterial test in this study was using the microdilution method using the ELISA Reader by measuring the Minimum Inhibitory Concentration (MIC) of ethyl acetate fraction of ant-plant tubers towards Streptococcus sanguis with positive control was using the chlorhexidine gluconate as the golden standard medication. The ethyl acetate fraction of ant-plant tuber had an antibacterial effect towards Streptococcus sanguis in the MIC of 31.25 ppm, while chlorhexidine gluconate was 0.49 ppm. Conclusion: The ethyl acetate fraction of ant-plant had a lower antibacterial activity compared to chlorhexidine gluconate on the growth of Streptococcus sanguis ATCC 10566.Keywords: Ant-plant tubers, Myrmecodia pendens Merr. & Perry, antibacterial activity, Streptococcus sanguis ATCC 10566.

Introduction: Age estimation has an important role in the process of human identification and needs to be performed in an efficient, fast, and accurate ways. Age estimation based on the pulp cavity volume of canines was referring to the theory stated that the apposition of secondary dentine during human life could be determined as an age indicator. This study was aimed to estimate the human age based on the pulp volume of canines for chronological estimation. Methods: Forty-one canine teeth from Cone Beam Computed Tomography (CBCT) 3D image sample from Dental Hospital of the Faculty of Dentistry Universitas Padjadjaran segmented into dental pulp and enamel were prepared for measurement of pulp volume using the ITK SNAP volumetric software. Descriptive analysis of pulp volume and regression equations were generated from regression analysis of pulp volume and tested for age estimation. Result: Dentine thickness was found to be increased from adolescence age range until adulthood age range. Logarithmic regression between pulp volume was statistically significant (p < 0,001). The coefficient of determination (R2) was 0.753 with a standard deviation of 8.421. Mathematics model for estimating age was: Age = 79.523 – (18.194 x ln(Pulp Volume)). The pulp cavity and dentine thickness were decreasing along the age. The same equation was also used in the same sample. There were several differences between chronological age and estimated age approximately 8.4 years following the regression result of R2 (75.3%). The rest of the sample (24.7%) have a big difference, and this could be affected by modifying variables such as occlusal force and human error measurement procedures. Conclusion: The human age can be estimated by the pulp volume of canines.Keywords: Age estimation, pulp volume, canine, ITK-SNAP, CBCT.

The most common chronic inflammation involved dental and oral tissue is gingival polyp, pulp polyp, and fibroma that are proliferative non neoplastic and neoplastic condition. Chronic inflammation will induce cells and vascular proliferation as well as biological nature lesion. Previous study revealed that increase macrophage followed by increase angiogenesis intensity. Increase angiogenesis or vascular proliferation indicates progressive growth in form of proliferative non neoplastic or neoplastic disease outside of their easily bleeding clinical features. This study evaluated macrophage and angiogenesis intensity and their correlation within such oral lesions. Samples used are of oral mucosa excision with clinical diagnose of gingival polyp (n=3); pulp polyp (n=3); and fibroma (n=3). Macrophage was detected using immunostaining with CD68 antibody resulted in brown staining cell membrane under light microscope while angiogenesis intensity evaluated as number of blood vessels. The results showed there was mild positive correlation of angiogenesis intensity and CD68+ as macrophage marker with r=0.31. The angiogenesis intensity showed significant differences (p<0.05) with the highest was in pulp polyp (12.00) followed by fibroma (11.81) and gingival polyp (9.67), however there was no significant difference between non neoplastic lesion (pulp polyp) and neoplastic lesion (fibroma). The CD68+ expression showed no significant differences (p=0.102>0.05) with the highest was in fibroma (51.32±31.64%) followed by non neoplastic pulp polyp (45.82±15.94%) and gingival polyp (29.98±13.51%). This result was in accordance with the biological properties of lesions from the aspect of angiogenesis and macrophage intensity that can be used as parameter for determining the growth and prognosis of lesion.

Introduction: The IRF6 rs2235373 (C/T) is a polymorphism in the intron region that has been associated with non-syndromic cleft lip and palate (NS CLP) among some populations. Polymorphism in introns can also affect the transcription that should be detected through some changes in IRF6 mRNA expression. This study was aimed to evaluate the effects of IRF6 rs2235373 polymorphism on mRNA expression changes in NS CLP with its phenotypes which include complete unilateral (CU) CLP, complete bilateral (CB) CLP, cleft lip only (CLO), and cleft palate only (CPO). Methods: This study was a laboratory analytical study, using samples from 198 individuals in Indonesia (136 individuals with NS CL/P consisted of CU CLP (n=42), CB CLP (n=34), CLO (n=33), CPO (n=27), and 62 individuals as controls). DNA was extracted from venous blood, and the segment of rs2235373 was evaluated by PCR and Sanger sequencing. mRNA expressions analysis preceded by RNA extraction from oral epithelium, then real-time (RT) PCR was performed. mRNA expression changes were analysed by Livak method and Kruskal Wallis test followed by the Mann Whitney test through CC, GT, and TT genotype. Result: The mRNA expression of TT genotype from NS CU CLP and control was 3.36 higher value than CC genotype (p=0.008), and the mRNA expression of CT genotype from NS CB CLP and control was 0.16 lower value than CC genotype (p=0.000). Conclusion: The IRF6 rs2235373 polymorphism of TT genotype tend to cause mRNA overexpression in NS CU CLP, and CT genotype tend to cause mRNA underexpression in NS CB CLP.Keywords: Non-syndromic cleft lip and palate, NS CLP phenotype, IRF6, rs2235373, mRNA expression.
