Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Introduction: Several factor limits of services of dental composite have triggered further improvement. ZrO2-Al2O3-SiO2 system as filler of dental composite had been developed with sol-gel technique. Ultrasonic homogeniser were reported to change the particle size ditribution or shape. Unifom size and distribution of particle is believed to help define the behavior of hardness properties. Methods: The study was an laboratory experimental design. Filler ZrO2-Al2O3-SiO2 system were developed via sol-gel methods. Post calcination process, filler were immerse in ethanol and applied with ultrasonic homogeniser, with various amplitude i.e 50 rpm, 60 rpm and 80 rpm then named sample A, B, and C. XRD, SEM anda PSA were used to characterize of filler system. Subsequent filler were used to fabricate dental composite then evaluate the hardness value using micro-hardness tester. One??way ANOVA was used to analysis the statistical result of hardness value. Results: XRD pattern of three sample were similar in which tetragonal zirconia was prominent (57-61 %) followed by monoclinic zirconia (24-25%) and amorphous (15-17 %). While, SEM and PSA characterization showed amplitude 50 rpm (sample A) produce more uniform size and well-distributed particle filler than the others. In contrary, sample B and C showed higher peak in PSA results. It means there was dominating of filler with particular size.  However, the hardness value did not show significant differences between those filler (p>0,05). Conclusion: Dental composite that contain of different uniformity and distribution of filler ZrO2-Al2O3-SiO2 system has no significantly differences of hardness value.
