ABSTRACTIntroduction: Calcite (CaCO3) is typically used in commercial toothpaste with particle size ranges from 1-12 μm. In the latest study, calcite was synthesized by using Ca(OH)2 precursor from natural resources However, the resulting particle size does not match the size of the toothpaste filler. This study aims to prepare micro-calcite via fine-bubble assisted carbonation as toothpaste material. Methods: The calcite powder was prepared from Ca(OH)2 analytical grade powder utilizing the fine-bubble carbonation process with the Ca(OH)2 concentration and initial pH variation. The study was started by making a Ca(OH)2 suspension with a concentration of 0.25, 0.5, 0.75, 1 and 1.25 M using 2.000 ml methanol as a solvent. 0.5 M NaH2PO4 solutions were utilized to adjust the initial pH of 0.5 M Ca(OH)2 suspension into 8, 9, and 10. The suspensions were aerated using CO2 fine-bubble for two hours to produce CaCO3 samples. All precipitated CaCO3 particles were characterized by PSA, Zeta-Potential, and FTIR measurements. Results: The calcite phase was identified from the FTIR transmittance. Aragonite or vaterite phase was not observed in the samples. PSA result shows the size of CaCO3 particles from samples 0.25 M to 1.25 M are as follows 3.03, 3.23, 2.79, 3.70, 0.99 μm respectively. Meanwhile, the particle sizes of CaCO3 in samples with a pH of 8, 9 and 10 are 3.00, 2.03 and 2.50 μm respectively. The zeta potential shows the value ranges from -23.2 mV to -11.9 mV, indicating fair dispersion ability. Conclusion: The fine bubble assisted carbonation method in this study helps in producing calcite in micron size that could be used as alternative fillers for toothpaste.Keywords: calcite, fine-bubble, carbonation, particle size, toothpaste

ABSTRACTIntroduction: one of the important components in dental composites is a filler which can be made through various methods, including spray pyrolysis. In the spray pyrolysis method, some factors determine the size and morphology of the resulting filler particles, one of which is the concentration of precursors. This study aimed to analyze the effect of precursor concentration on the particle size produced using the spray pyrolysis method. Methods: in this experimental laboratory study, zirconia-alumina-silica particles were synthesized using the spray pyrolysis method. The precursor solution consisted of ZrCl4, Al (NO3)3, and Na2SiO3 with a concentration variation of (0.1; 0.2; and 0.3) M. The furnace temperature was set at 750°C, and the electric precipitator temperature was 100°C with a feed rate of 3L/min. Then, the tests performed were using PSA (Particle Size Analyzer), and XRF (X-Ray Fluorescence). Results: The results showed that the best zirconia alumina silica filler particle with the smallest size is the result with a concentration of 0.1 M and its size was 618.6 nm. The particle size for 0.2 M was 911.9 nm and 1799.4 nm for 0.3 M. According to XRF test results the zirconia alumina silica filler system contains all the precursor elements. Conclusions: The effect of precursor concentration on the particle size produced using the spray pyrolysis method showed that the smaller the precursor concentration used, the smaller the particle size produced. The best results from synthesizing a filler system with a concentration of 0.1 M precursor solution. All the results are in submicron and micron size, and could be used as the component of dental composites.Keywords: precursors concentration, particle size, spray pyrolysis, dental composites filler

ABSTRACTIntroduction: A lack of knowledge of oral health maintenance among pregnant women affects the behavior of maintaining poor oral health. It is important for pregnant women to visit the dentist due to their increased susceptibility to oral diseases, which can adversely impact pregnancy outcomes, including premature birth and low birth weight. According to the theory of planned behavior, a mother's knowledge can influence her health-related behavior. To determine the level of oral health knowledge among pregnant women and to examine the relationship between this knowledge and the factors that influence their behavior regarding dental visits. Methods: This study uses a correlational analytical design with a cross-sectional approach, focusing on pregnant women at the Cijerah Community Health Centerin Bandung City, Indonesia. A purposive sampling method resulted 67 participants. A new questionnaire assessed oral health knowledge (20 items) and factors influencinh visiting behavior based on the theory of planned behavior (26 items). Data analysis used the Spearman correlation test. Results:Most pregnant women (76.2%) had insufficient oral health knowledge, but showed a positive attitude towards dental visits in the first trimester and every six months (11.91 ± 2.66 and 11.65 ± 2.87). They also reported good subjective norm (28.73 ± 5.42 and 28.31 ± 5.19), good behavioral control (8.23 ± 1.67 and 8.32 ± 1.61) and good intention (3.94 ± 0.96 and 3.83 ± 1.06). Conclusion: The level of oral health knowledge is low, and althoughfactors influencing the dental visit behavior are positive, there is no correlation between this knowledge and factors that influence the behavior of visiting the dentist.

ABSTRACTIntroduction: The application of calcium carbonate in dental biomaterial depends on the charcateristics after the synthesis process. This study aims to determine the effect of the ratio of methanol and water on the characteristics of the CaCo3 produced through the fine bubble diffuser method. Methods: Synthesis of calcium carbonate by CO2 carbonation method using fine bubble diffuser to produce fine CO2 bubbles (bubble size range 100-500 nm). The Ca(OH)2 precursor was dissolved in various ratios of water and methanol mixtures, namely: 25% water 75% methanol, 20% water 80% methanol, 15% water 85% methanol, 10% water 90% methanol, 5% water 95% methanol, and 100% methanol. The suspension was carbonated using CO2 fine bubbles for 2 hours to produce CaCO3 powder. The resulting calcium carbonate powder was tested with FTIR (Fourier Transform Infra Red), PSA (Particle Size Analyzer), and Zeta-Potential. Results: The FTIR test obtained the wave numbers of calcite (712 cm-1), vaterite (744, 873, 874, and 875 cm-1) and aragonite (848, 849, and 854 cm-1) phases in the six variations of the solvent used. The PSA test showed that the particle size produced was submicron with the smallest size being 191.1 nm and the largest being 576.2 nm. The ZetaPotential test showed that the particles were relatively stable in solution with a Zeta-Potential value range of -15.1 mV to -20.8 mV and particles with moderate stability -21.2 mV to -25.1 mV. Conclusion: The addition of the organic solvent methanol to water increases the solubility of CaOH and increases the formation of the vaterite phase. Increasing the amount of water decreases the amount of vaterite phase, increasing the particle size and zeta potential value. but the addition of 15% water decreases the particle size of CaCO3 KEY WORDSCaCO3, fine bubble diffuser, FTIR, PSA, zeta potential Pengaruh perbandingan campuran pelarut air dan metanol terhadap karakteristik CaCO3 melalui metode fine bubble diffuser sebagai biomaterial kedokteran gigiABSTRAKPendahuluan: Kalsium karbonat (CaCO3) merupakan salah satu sumber kalsium yang umum digunakan di bidang biomaterial kedokteran gigi.
