Perbedaan karakteristik struktur email pasca aplikasi pasta stolephorus sp. dan casein phosphopeptide-amorphous calcium phosphate fluoride (pemeriksaan kekerasan dan mikroporositas email)
L Latar Belakang: Proses demineralisasi gigi dapat menyebabkan larutnyakomponen mineral pada kristal hidroksiapatit, menghasilkan celah interprismatikyang lebih besar dan menurunkan kekerasan email. Demineralisasi dapat dihambatdengan proses remineralisasi. Proses remineralisasi dapat dibantu dengan bahankedokteran gigi topikal seperti CPP-ACPF, namun terdapat juga bahan alam sepertiStolephorus sp. yang berpotensi menjadi agen remineralisasi. Tujuan:Menganalisis perbedaan kekerasan dan mikroporositas email pasca aplikasi pastaStolephorus sp. dan casein phosphopeptide-amorphous calcium phosphatefluoride. Metode: 30 premolar untuk pengukuran kekerasan dan 3 premolar untukanalisis mikroporositas dibagi menjadi 3 kelompok. Kelompok A merupakankelompok yang diberi perlakuan pasta Stolephorus sp., kelompok B merupakankelompok yang diberi perlakuan CPP-ACPF, dan kelompok C sebagai kontrolnegatif direndam dalam akuades. Seluruh kelompok diberikan perlakuan selama 5menit dan direndam dalam saliva buatan yang diinkubasi dalam suhu 37°C setiapharinya selama 14 hari. Kekerasan email diukur dengan Vickers Hardness Testerdan mikroporositas email dilihat dengan Scanning Electron Microscopy withEnergy Dispersive X-ray Spectroscopy (SEM/EDX). Hasil: Uji One-Way ANOVAmenunjukkan bahwa terdapat perbedaan yang signifikan antar kelompok sesudahdiberikan perlakuan. Dependent T Test menunjukkan adanya peningkatankekerasan secara signifikan sesudah diberikan pasta Stolephorus sp. dan CPPACPF. Post Hoc Tukey menunjukkan kelompok pasta Stolephorus sp.meningkatkan kekerasan email terbanyak, namun tidak berbeda secara signifikandengan kelompok CPP-ACPF. Kesimpulan: Terdapat perbedaan struktur emailpasca aplikasi pasta Stolephorus sp. dan CPP-ACPF.
B Background: The process of dental demineralization can lead to the dissolution ofmineral contents in hydroxyapatite crystals, increasing the interprismatic spacesand decreasing enamel hardness. Demineralization can be inhibited throughremineralization. Remineralization could be supported by topical agents like CPPACPF, as well as natural ingredients such as Stolephorus sp., which have thepotential as remineralizing agents. Objective: To analyze the enamel hardness andmicroporosity differences after the application of Stolephorus sp. paste and caseinphosphopeptide-amorphous calcium phosphate fluoride. Methods: 30 premolarsfor enamel hardness measurement and 3 premolars for enamel microhardnessanalysis were divided into 3 groups. Group A received treatment with Stolephorussp. paste, Group B with CPP-ACPF, and Group C as the negative control, wasimmersed in distilled water. All groups were treated for 5 minutes, immersed inartificial saliva and placed inside the incubator at 37°C daily for 14 days. Enamelhardness was measured using Vickers Hardness Tester and the enamelmicroporosity was examined using SEM/EDX. Results: One-Way ANOVA testshowed a difference between the after-treatment groups. Dependent T-Test showedthat the enamel hardness was increasing significantly after the application ofStolephorus sp. paste and CPP-ACPF. Post Hoc Tukey indicated that Stolephorussp. paste group had the most significant enamel hardness increase, but notsignificantly different from the CPP-ACPF group. Conclusion: There arecharacteristics differences in enamel structure after the application of Stolephorussp. paste and CPP-ACPF
