Abstract

Background: Synthetic bone graft is a material that resembles human bone phase and is developed due to clinical demand. Calcium carbonte (CaCO3/Calcite) has been used as bone substitution one of the methods to fabricate calcite is phase transformation by dissolution–precipitation reaction.  Previous study did the same method but with lower temperature (<100ºC). Calcium sulfate anhydrate (CaSO4) granules used as precursor is immersed in 0.5 mol/L sodium carbonate (Na2CO3) solution at 100ºC for 12 h.  Objective: This study aims to fabricate CaCO3 granules from CaSO4 granules when the temperature is higher than the previous study. Methods: Fabricate CaCO3 granules using CaSO4 granules as precursor by dissolution-precipitation reaction in Na2CO3 solution with 12 h immersion time with 100ºC temperature. Powder X-ray diffraction patterns and Fourier transform infrared spectra study will be performed to characterize the granules. Results:  CaCO3 granules are fabricated by dissolution-precipitation reaction in Na2CO3 solution with 12 h immersion time when the temperature was 100ºC. Conclusion: CaSO4 granules used as precursor are a potential material to fabricate CaCO3 by using dissolution-precipitation reaction with 12 hours immersion time and 100ºC temperature.

Abstract

Pendahuluan: Dental implan saat ini sudah menjadi pilihan perawatan untuk menggantikan gigi yang hilang. Keberhasilan dari perawatan implan bergantung pada kemampuan materialnya untuk berintegrasi dengan lingkungan sekitarnya. Makalah ini bertujuan untuk membahas modifikasi permukaan implan dengan pengaplikasian HA menggunakan teknik plasma spray  dan sol-gel dip serta  bagaimana respons logam implan dan tulang dengan adanya aplikasi HA. Metode: Penelitian ini menggunakan pencarian pada database di jurnal pada Sciencedirect, Pubmed tentang material kedokteran gigi dan sains yang bereputasi internasional dengan menggunakan kata kunci titanium implant, surface modification, plasma spray method, sol-gel dip method, hydroxyapatite, coating dan osseointegrasi. Hasil: Osseointegrasi dapat dipengaruhi oleh material implan yang digunakan. Material implan umumnya dibuat dengan titanium alloy yang dilapisi hidroksiapatit. Lapisan hidroksiapatit yang menempel pada permukaan implan merupakan hasil modifikasi dengan teknik plasma spray dan sol-gel dip. Simpulan: Teknik modifikasi permukaan implan plasma spray lebih baik dibandingkan permukaan implan sol-gel dip. Hal ini karena parameter pelapisan HA pada permukaan implan dengan metode plasma spray memenuhi nilai standar kristalinitas HA, kemurnian HA, dan kekasaran permukaan yang baik. Dengan memodifikasi permukaan logam dengan HA maka akan terjadi proses adhesi HA dengan implan, yang merupakan salah satu faktor pendukung terbentuknya osseointegrasi.   Kata kunci : Implan, osseointegrasi, modifikasi permukaan, plasma spray, sol-gel dip. ABSTRACTIntroduction: Dental implants are now the treatment of choice for replacing lost teeth. The success of implant treatment depends on the ability of the material to integrate with the surrounding environment. This paper aims to discuss the surface modification of the implant by the application of HA using the Plasma Spray and Sol-Gel Dip technique and how the implant and bone metal respond to the application of HA. Methods: This study used a database search in the journal ScienceDirect, Pubmed on dentistry and science materials with international reputation using the keywords titanium implant, surface modification, plasma spray method, sol-gel dip method, hydroxyapatite, coating and osseointegration. Results: Osseointegration can be affected by the implant material used. The implant material was generally made with titanium alloy coated with hydroxyapatite. Hydroxyapatite coating attached to the surface of the implant is the result of modification with the Plasma Spray and Sol-Gel dip technique. Conclusion: The surface modification technique for Plasma Spray implants is better than the Sol-Gel Dip implant surface. This is because the HA coating parameters on the surface of the implant using the Plasma Spray method meet the standard values of HA crystallinity, HA purity, and good surface roughness. By modifying the surface of the metal with HA the HA adhesion process with implants will occur, which is one of the supporting factors for the formation of osseointegration.Keywords: Implants, osseointegration, surface modification, plasma spray, sol-gel dip.

Abstract

ABSTRACTIntroduction: Tooth bleaching enhances aesthetics but may increase enamel surface roughness, leading to food particle accumulation and biofilm formation. This study aims to evaluate the effect of fluoride varnish on the enamel surface roughness after bleaching. Methods: Thirty-six premolar specimens were divided into six groups: HP-35% with Clinpro White Varnish (3M-ESPE), HP-35% with MI Varnish (GC Corp), HP-3% with Clinpro White Varnish (3M-ESPE), HP-3% with MI Varnish (GC Corp), and two control groups immersed in HP-35% and HP-3%, followed by artificial saliva immersion. Surface roughness was measured initially, after bleaching (HP-35% for 1 hour or HP-3% for 42 hours), and after remineralization (6 hours at 37°C). Data were analyzed using the Friedman test. Results: Statistically significant differences (p<0.05) were observed in mean surface roughness before and after HP immersion, as well as between post-bleaching and post-FV application. However, despite a reduction in roughness values, no significant differences (p>0.05) were found between initial and post-FV application. Conclusions: The enamel surface roughness of bleached teeth exhibited varying effects depending on the treatment. Roughness increased after immersion in HP-35% and HP-3% solutions, but decreased following the application of FV Clinpro White Varnish (3M-ESPE) and MI Varnish (GC Corp).KEY WORDS: Enamel surface roughness, fluoride varnish, hydrogen peroxide, demineralization, remineralizationEfek aplikasi fluoride varnish pada gigi yang telah dilakukan pemutihan gigi terhadap kekasaran permukaan email: Studi eksperimentalABSTRAK Pendahuluan: Penggunaan material pemutih gigi dapat meningkatkan estetika, namun berisiko meningkatkan kekasaran permukaan email, yang dapat memicu akumulasi partikel makanan dan pembentukan biofilm.

Abstract

Dental caries and gingivitis can be mitigated through the use of mouthwashes. However, chemical-based mouthwashes are associated with several adverse effects. Safer alternatives to chemical mouthwashes incorporate natural ingredients. Chitosan and green tea have gained prominence in the synthesis (formulation) of mouthwashes, with a focus on characterizing their antibacterial properties. This overview will concentrate on the synthesis methodology, characteristics, and antibacterial efficacy of chitosan and green tea. Chitosan and green tea mouthwashes can be synthesized using the solubilization method. This method entails the creation of a thermodynamically stable, isotropic solution of a substance in water by the addition of a surfactant. Chitosan is distinguished by the presence of glucosamine and N-acetylglucosamine repeating units, both of which contain amino groups. These amino groups exhibit antibacterial properties by interacting with bacterial cell membranes and compromising their structural integrity. In green tea, compounds such as catechins within phenolic groups, including flavanols, flavandiols, and flavonoids, also function as agents by disrupting bacterial cell membranes and cytoplasmic membranes. Both amino groups and catechin compounds demonstrate the ability to inhibit pathogenic oral bacteria. In conclusion, the potentially anti-bacterial activity mouthwashes synthesized from chitosan and green tea, in the future chitosan and green tea extracts to be further used for the preparation of mouthwash.
