Abstract

Using a disclosing agent to control plaque is one way to improve dental health and oral tissue. However, this material is not widely known to the public. Red dragon fruit, a mainstay commodity in Blitar Regency, contains betalain which can be used as an alternative disclosure agent. Therefore, the people of Blitar Regency need to be empowered to maintain dental and oral health regarding the potential of dragon fruit as an alternative natural ingredient. The aim is to provide education regarding the potential benefits of dragon fruit as a disclosure agent. The strategy used in this activity is dual media intervention by dentists, namely by using interactive lectures with PowerPoint media and booklet media to community groups in, Blitar Regency. To measure the level of knowledge of the target community, questionnaires were given before and after the activity, as well as checking the OHI-S index. The research results showed that the level of the OHI-S index was in the medium category, while the level of community knowledge showed an increase of 56.78% after being given counseling. This shows that providing dental and oral health education using PowerPoint media and booklet media has proven to be effective in increasing public knowledge. Therefore, it can be concluded that providing education on the use of red dragon fruit as a disclosing agent to the people of Blitar Regency has proven effective in increasing knowledge, so it is hoped that it can improve the community's dental and oral hygiene.

Abstract

Background: Fiber is added to composite resin with the aim of increasing strength. The strength of composite resin is influenced by water absorption. Samia ricini silk fiber has semihydrophilic properties which can affect water absorption in FRC. One of the ways FRC water absorption is influenced by volumetric fraction. Objective: to determine the effect of the volumetric fraction of Samia ricini silk fiber ribbon in FRC on water absorption. Method: The materials used in this research were flowable composite resin and Samia ricini fiber. The samples were made into 3 groups with varying volumetric fractions of 0%, 25% and 50%, with each group having 6 samples. The sample was then weighed to an accuracy of 0.0001 g, then soaked in water for 7 days in an incubator. After 7 days, weighing was carried out again to calculate the weight percentage of water absorption in the FRC. The data obtained was then analyzed using One Way ANOVA. Results: This research show that water absorption has increased in line with the increase in volumetric fraction. The percentage of water absorption in the volumetric fractions of 0%, 25%, and 50% respectively is 0.5298 ± 0.1190%, 0.8430 ± 0.3191%, and 0.9382 ± 0.4215%. The results of the One Way ANOVA analysis show F = 2.798 with a significance of 0.093 so that the three volumetric fraction groups do not have significant differences. Conclusion: Volumetric fraction does not significantly influence the water absorption of composite resin during 7 days of immersion.

Abstract

Calcium carbonate derived from eggshells has significant potential for use in drug delivery systems, pharmaceutical, food, catalyst, cement, and concrete industries. Although eggshell waste is non-toxic, its excessive accumulation in the environment may contribute to ecological issues. Colonizing pathogenic bacteria in unprocessed eggshell waste poses a potential health risk. The present study outlines the production of precipitated calcium carbonate (PCC) from eggshell waste through a calcination-carbonation process, offering a sustainable approach to its utilization. The calcination was carried out at 900 ºC. The carbonation process was performed in an HNO3 solution, and the NH3 solution was under-treated for 60 minutes. The results exhibited that the precipitated calcium carbonate (PCC) had a purity of 95.2% CaO. It possessed predominantly the calcite phase with a rhombohedral crystal system, as confirmed by the XRD analysis. The crystallite size of PCC was 109.5 nm, measured using the Debye-Scherrer equation. The phase composition of PCC was 99.3% calcite, 0.5% vaterite, and 0.2% aragonite. FTIR analysis further corroborated this data by showing a sharp and unsplit peak at 1419 cm-1, demonstrating the presence of a calcite phase. SEM images revealed a cubic-like morphology, a characteristic of the calcite form of calcium carbonate (CaCO3). The synthesized calcium carbonate in this study holds potential for applications in dental materials and as fillers in polymer matrices for food packaging.

Abstract

Glass fiber lebih sering digunakan daripada polyethylene fiber sebagai komponen FRC dalam dunia kedokteran gigi. Glass fiber dental di Indonesia tersedia dalam jumlah terbatas dan memiliki harga yang relatif mahal. Tujuan dari penelitian ini adalah untuk memeriksa komposisi dari E-glass fiber dental dan glass fiber non dental menggunakan teknik XRF sehingga dapat ditentukan tipe dari masing-masing glass fiber non dental. Sampel terdiri dari 10 g E-glass fiber dental, 10 g fiberglass mats, 10 g fiberglass roving dan 10 g woven roving. Masing-masing sampel dihaluskan, selanjutnya dianalisa dengan dengan menggunakan X-Ray Fluorescence Spectrometer (XRF). Hasil analisa XRF sampel menunjukkan kandungan oksida terbesar pada E-glass fiber dental adalah SiO2 (45,47%), CaO (38,49%) dan Al2O3 (12,11%). Kandungan oksida terbesar pada fiberglass mats adalah SiO2 (56,88%), CaO (16,24%) dan Na2O (12,91%) demikian pula dengan woven roving yaitu SiO2 (55,86%), CaO (18,71%) dan Na2O (11,80%). Sedangkan fiberglass roving menunjukkan kandungan oksida terbesar antara lain SiO2 (52,56%), ZrO2 (14,64%) dan CaO (10,03%). Hal tersebut menunjukkan bahwa komposisi kandungan oksida pada sampel memiliki kemiripan dengan persentase yang berbeda. Berdasarkan pada analisis XRF disimpulkan bahwa glass fiber non dental jenis fiberglass mats dan woven roving mengarah ke tipe C-glass dan fiberglass roving mengarah ke tipe AR-glass.
