"Penelitian ini membahas pengaruh kimia dari xylitol terhadap remineralisasi enamel yang sebelumnya mengalami demineralisasi. Sampel email yang berasal dari gigi yang telah diekstraksi untuk kepentingan perawatan orthodonti didemineralisasi terlebih dahulu dan selanjutnya direndam dalam larutan remineralisasi yang mengandung 20% dan 50% xylitol pada suhu 37⁰C selama dua minggu. Sampel lalu dianalisis menggunakan metode Energy Dispersive Xray (EDX) dan X-ray Diffraction (XRD). Hasil berdasarkan EDX mengindikasikan terdapat peningkatan jumlah kalsium dan fosfor pada sampel yang direndam dalam larutan remineralisasi dengan xylitol 50% dibandingkan dengan sampel yang mengalami demineralisasi tanpa direndam dalam larutan remineralisasi dengan xylitol 50% (p < 0.05). Tidak terdapat peningkatan bermakna dari kalsium dan fosfor pada sampel yang direndam dalam larutan remineralisasi dengan xylitol 20% dibandingkan dengan sampel yang mengalami demineralisasi tanpa direndam dalam larutan remineralisasi dengan xylitol 20% (p > 0.05).Identifikasi komposisi senyawa kristal dengan metode XRD menunjukkan berbagai macam kristal apatit pada sampel yang berbeda. Hidroksiapatit dan fluorapatit ditemukan ada sampel kontrol yang tidak didemineralisasi. Material amorphous ditemukan pada sampel yang didemineralisasi untuk kontrol perlakuan xylitol 50%. Fluorapatit ditemukan pada sampel yang didemineralisasi untuk kontrol perlakuan xylitol 20%. Fluorapatit juga ditemukan pada sampel yang direndam pada larutan remineralisasi dengan xylitol 20% dan 50%. Hasil ini mengindikasikan bahwa xylitol dapat meningkatkan jumlah kalsium dan fosfor dengan menghambat presipitasi kalsium dan fosfat serta bertindak sebagai calcium carrier. Sifat xylitol tersebut dapat mempengaruhi reaksi kimia dari kalsium dan fosfor pada plak, saliva, dan lesi karies. Oleh karena itu, substansi amor phous dari email dapat berubah menjadi kristal apatit seperti fluorapatite. Dengan demikian, xylitol menunjukkan kemampuan untuk mencegah karies dan merestorasi lesi dini karies.

This study aimed to determine the effects of xylitol exposure on the remineralization of artificially demineralized enamel. Samples that were obtained from teeth extracted due to orthodontic treatment were demineralized and then immersed in a remineralizing solution with 20% or 50% xylitol at 37°C for 2 weeks. The samples were analyzed using Energy Dispersive X-Ray (EDX) and Xray Diffraction (XRD) methods. The EDX results indicated that calcium and phosphorus contents were significantly higher in samples that had been immersed in 50% xylitol solution, compared to demineralized samples without such immersion treatment (p < 0.05). There was no significant increase in calcium and phosphorus content for samples that had been immersed in 20% xylitol solution compared to demineralized samples without this immerson treatment (p > 0.05).Identification of crystal compounds by XRD showed the presence of hydroxyapatite and fluorapatite in untreated samples. Amorphous materials were found in demineralized control samples for 50% xylitol solution. Fluorapatite was identified in demineralized control samples for 20% xylitol solution. Fluorapatite was also identified in samples that had been immersed in 20% and 50% xylitol solution. The results indicate that exposure to xylitol c an increase calcium and phosphorus contents in enamel, probably by inhibiting Ca2+ and PO43- precipitation and acting as calcium carrier. Xylitol exposure may influence the chemical reactions of calcium and phosphorus in plaque, saliva and caries lesions. Through the influenced reactions, amorphous substance of enamel could change into apatite crystal such as fluorapatite. Thereby, xylitol demonstrate caries prevention and possible restoration of initial enamel caries lesions."

"Karies gigi merupakan salah satu penyakit infeksi jaringan keras gigi yang sangat banyak menyerang penduduk Indonesia, dengan tingkat prevalensi lebih dari 90%. Karies terjadi sebagai akibat ketidakseimbangan proses demineralisasi dan remineralisasi yang terjadi pada permukaan gigi, yaitu pada saat tingkat demineralisasi terjadi lebih tinggi daripada remineralisasi.

Dental caries is one of the infection diseases on the tooth. Its prevalence in Indonesia is more than 90%. Caries happened when there is unbalance condition between demineralization and remineralization process, which is higher in demineralization. To prevent the dental caries, there should be preventive programs that can be reached by all people. One agent believed to control and reduced dental caries is xylitol. This research observed the enamel surface?s structure related remineralization effects of xylitol on artificially demineralized enamel. The samples were demineralized in an acid solution with 4.0 pH level for two days. After that, they`re immersed in a remineralized solution containing 20% or 50% xylitol at 37oC for two weeks. Samples were analyzed using SEM to see the quality difference between the control samples and the other one on the enamel?s surface. SEM analyzing indicated that remineralization happened in enamel?s surfaces. The enamel?s surfaces remineralized with solution containing 50% xylitol had a better change after remineralization than the 20% did. These results mean that xylitol can avoid caries by inducing remineralization and inhibit demineralization."

"Tujuan penelitian ini adalah mempelajari pengaruh pemaparan xylitol pada email yang telah terdemineralisasi terhadap remineralisasi ditinjau dari kekerasan email. Demineralisasi dilakukan dengan larutan asam asetat 0.01 Μ (pH 4.0) pada suhu 50°C selama 2 hari. Untuk remineralisasi, sampel kemudian direndam dalam larutan remineralisasi dengan konsentrasi xylitol 20% atau 50% pada suhu 37°C selama 2 minggu. Kekerasan email dari sampel dengan dan tanpa xylitol diuji menggunakan alat uji kekerasan Vickers. Hasil menunjukkan adanya perbedaan kekerasan email antara kelompok yang diberi aplikasi larutan remineralisasi berxylitol dengan kelompok kontrolnya (p<0.05). Kelompok yang direndam dalam larutan remineralisasi ber-xylitol menunjukkan nilai kekerasan yang lebih besar daripada kelompok kontrolnya. Kekerasan email berkisar antara 423 ± 45 VHN pada kelompok larutan remineralisasi ber-xylitol 20%, sedangkan kelompok kontrolnya menunjukkan nilai 302 ± 60 VHN. Kelompok yang direndam dalam larutan remineralisasi ber-xylitol 50% menunjukkan nilai kekerasan 367 ± 70 VHN, sedangkan kelompok kontrolnya menunjukkan nilai 252 ± 100 VHN. Ini dikarenakan kemampuan xylitol untuk membentuk kompleks dengan ion-ion kalsium, hal ini membantu remineralisasi, sehingga lebih lanjut meningkatkan kekerasan dari email yang terdemineralisasi. Fungsi utama kalsium adalah untuk kekerasan tulang dan gigi.

This study aimed to determine the effects of xylitol exposure of demineralized enamel on remineralization in terms of enamel microhardness. The demineralizing treatment was done with a 0.01 Μ acetate buffer solution (pH 4.0) at 50°C for 2 days. For remineralization, the enamel samples were then immersed in a solution with 20% or 50% xylitol at 37°C for 2 weeks. Hardness of the enamel samples with and without xylitol treatment was measured as Vickers microhardness. Results showed differences of enamel microhardness between the group that is immersed in remineralizing solutions with xylitol and the control group (p < 0.05). Groups that is immersed in remineralizing solutions with xylitol showed higher microhardness values than its control groups. The enamel microhardness ranged between 423 ± 45 VHN on samples that are immersed in remineralizing solution with 20% xylitol, while its control group showed 302 ± 60 VHN in microhardness test. Samples that were immersed in remineralizing solution with 50% xylitol showed 367 ± 70 VHN in microhardness test, while its control group result in 252 ± 100 VHN. This is caused by the xylitol?s capability to form complexes with calcium ions, which helps the remineralization process and further increase the microhardness of the demineralized enamel. The major function of calcium is to provide rigidity and strength to bones and teeth."

ABSTRACT

Background: Dental caries is a multifactorial disease caused by the interaction of the biofilm complex with carbohydrate sources attached to the surface of the teeth. One process that occurs in tooth enamel for caries formation is the process of tooth demineralization that occurs predominantly compared to the remineralization process. Efforts that can be made to prevent caries are by applying remineralization materials such as propolis fluoride and sodium fluoride. The use of remineralization materials can increase the hardness of email. Objective: Compares increased enamel hardness after application of propolis fluoride and sodium fluoride remineralization materials. Methods: 32 premolar tooth samples were divided into propolis fluoride and sodium fluoride groups. All specimens were planted in paralon pipes and finalized and polished. All specimens were subjected to initial hardness tests. Then demineralization was done using Buavita® (pH 3.85). After that the specimens were measured hardness, then propolis fluoride and sodium fluoride were applied and soaked in artificial saliva for 3 days. After that, the final violence measurement and compared statistically. Results: Sodium Fluoride is more effective in increasing the hardness compared with Propolis Fluoride, and there were also significant differences in demineralized tooth enamel and tooth enamel hardness after remineralization.. Conclusion: There is a significant difference between increasing enamel hardness when applying propolis fluoride and sodium fluoride."

"Topical fluoridation recently has become the method of choice in caries prevention. Flouride plays an important role not only in the formation of fluoroapatite, but also promoting enamel remineralization. Enamel remineralization occur when the enamel environtment supersaturated with calcium and phospate ions. When the pH level decrease, the rise of H ions, the hydroxyl of the apatite will be drawn out from the enamel, and substitute by fluoride ion, this condition will causes apatite breakdown and both calcium and phosphate will be released to the enamel environment. The release of those minerals, will cause supersaturation and promoting enamel remineralization. In the nature fluoride can be found in the sea fishes, such like teri (anchovy, Stolephorus sp) fishes. Teri fish has about 17-38 ppm of fluoride content. The high fluoride content of teri fish, lead this research to know the influence of it's application to the enamel surface on remineralization process, measured with enamel surface roughness and hardness tests. Seven enamel discs, 5 x 10 mm (W and L) obtained from 4 impacted third molars, were used in the research. One disc used as initial control, and 6 discs divided into 2 groups, used as experiment groups. All of the experimental discs demineralized using 50% phosphoric acid, then 3 of them were applied with teri substrate, wether other 3 discs applied with non ionic aquadest. All experimental discs, then immersed in the remineralization solution containing calcium phosphate stabilized with caseinphosphoptide. The cycle above repeated for 26 times. Analize of the specimens, were done using surfcom for enamel roughness and Buehler microhardness tester for surface hardness. Surface roughness of the teri group is 1,78 um compare to the initial group (215 um), and enamel surface microhardness of the teri group is (376 VHN), significantly differ from the control group, 358 VHN. Conclusion: Based on this research result, it can be concluded that : Teri fish substrate application on enamel surface causes the enhancement of enamel remineralization, as evaluated by surface roughness and micro hardness."

"Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 198-201Radiotherapy plays an important role in the management of head and neck carcinoma therapy. The radiation dose range from 40-70Gy, depends on the severity and location of the malignancy. Many patientsexperience an increased dental caries or sensitivity occurence following radiotherapy. The objective of this study is to analyze the enamel micro-structure changes after irradiation. Nine polished enamel slabs were prepared from impacted 3rd molars. The slabs were flushed in non-ionic distilled water and dried by using air spray and divided into 3 groups, the control, 20Gy and 40Gy irradiation group. lrradiations were performed from Co60 using Gammacell-220E, with duration variables to produce the irradiation doses of 20 and 40Gy. Philips PW370-XRD was used to examine specimen microstructure changes after irradiation. I-way ANOVA was used for statistics analyze. lt was revealed that grain size after 40Gy irradiation was 66.29±2.7 nm, andafter 20 Gy was 51.64±15.8 whilst 43.95±11.1 nm for the control group. The micro-strain deviation of the 40Gy group was 0.594±0.15 N/m, and 0.45±0.26 N/m for the 20Gy group, and 0.378±0.27 N/m for control group. Statistic analysis showed significant grain size differences between 40Gy compared to both 20Gy and control group, but not between 40Gy compared to the control group. Similarly, there were micro-strain differences between 40Gy compared to 20Gy and control groups, but not between 20Gy compare to control group. It was concluded that irradiation with 40Gy caused elevation of the enamel microstrain and apatite grain size. Elevation of the enamel microstrain could lead to enamel crack and gave hypersensitive sensation."
