Background: Caries process is characterized by the presence of demineralization. Demineralization is caused by organic acids as a result of carbohydrate substrate fermentation. Remineralization is a natural repair process for non-cavitated lesions. Remineralization occurs if there are Ca2+ and PO43- ions in sufficient quantities. Casein-amorphous calcium phosphate phosphopeptide (CPP-ACP) is a paste material containing milk protein (casein), that actually contains minerals, such as calcium and phosphate. The casein ability to stabilize calcium phosphate and enhance mineral solubility and bioavailability confers upon CPP potential to be biological delivery vehicles for calcium and phosphate. Purpose: The aim of this study was to determine the calcium levels in tooth enamel after being covered with CPP-ACP 2 times a day for 3, 14 and 28 days. Methods: Sample were bovine incisors of 3 year old cows divided into 4 groups, namely group I as control group, group II, III and IV as treatment groups covered with CPP-ACP 2 times a day. All of those teeth were then immersed in artificial saliva. Group II was immersed for 3 days, while group III was immersed for 14 days, and group IV was immersed for 28 days. One drop of CPP-ACP was used to cover the entire labial surface of teeth. The measurement of the calcium levels was then conducted by using titration method. All data were analyzed by One- Way ANOVA test with 5% degree of confidence. Results: The results showed significant difference of the calcium levels in tooth enamel of those groups after covered with CPP-ACP 2 times a day for 3, 14 and 28 days (p = 0.001). There is also significant difference of the calcium levels in tooth enamel of those treatment groups and the control group (p = 0.001). Conclusion: The calcium levels of tooth enamel are increased after covered with CPP-ACP 2 times a day for 3, 14 and 28 days.Latar belakang: Proses terjadinya karies gigi ditandai oleh adanya demineralisasi. Demineralisasi terjadi oleh asam organik sebagai hasil fermentasi substrat karbohidrat oleh bakteri. Remineralisasi adalah proses perbaikan alami untuk lesi non cavitated. Remineralisasi terjadi jika terdapat ion Ca2+ dan PO43- dalam jumlah cukup. Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) adalah bahan berbentuk pasta berisi suatu protein susu (kasein). Pada kasein terkandung mineral kalsium dan fosfat. Kemampuan kasein untuk menstabilkan kalsium fosfat dan meningkatkan kelarutan dan bioavailabilitas sehingga CPP memiliki potensi menghantarkan kalsium dan fosfat. Tujuan: Tujuan penelitian ini untuk mengetahui kadar kalsium enamel setelah pengulasan CPP-ACP pada permukaan enamel 2 kali sehari selama 3,14 dan 28 hari. Metode: Sampel adalah gigi insisif sapi, usia 3 tahun. Pada penelitian ini sampel (n = 24) dibagi menjadi 4 kelompok yaitu kelompok I sebagai kelompok kontrol, dan kelompok II, III, IV sebagai kelompok perlakuan dengan pengulasan CPP-ACP 2 kali sehari. Semua kelompok direndam dalam saliva buatan. Kelompok II direndam 3 hari, kelompok III direndam 14 hari, kelompok IV direndam 28 hari. Pengulasan CPP-ACP sejumlah 1 tetes diratakan pada seluruh permukaan labial gigi. Pengukuran kadar kalsium dilakukan dengan metode titrasi. Semua data dianalisa dengan uji One-Way ANOVA dengan taraf kemaknaan 5%. Hasil: Hasil penelitian menunjukkan perbedaan yang signifikan kadar kalsium enamel gigi di antara kelompok (p = 0,001). Hasil penelitian menunjukkan perbedaan yang signifikan kadar kalsium gigi pada kelompok kontrol dan perlakuan antara lama waktu pengulasan 3, 14, dan 28 hari (p = 0,001). Kesimpulan: Pengulasan CPP-ACP selama 3, 14 dan 28 hari mampu meningkatkan kadar kalsium pada enamel.

Background: Bone damage can be caused by various factors with treatment usually involving graft materials being applied to the defective area. Moreover, in the bone defect healing process, blood vessels are also considered to be an important energy source for cell proliferation. One of the angiogenic factors playing an important role in blood vessel formation is basic fibroblast growth factor (bFGF). Furthermore, synthesized hydroxyapatite derived from Anadara granosa (AG) shells constitutes one of the potential materials for use in bone graft. The gold sea cucumber genus Stichopus hermanni (SH) possesses the ability to stimulate endothelial progenitor cells inducing bFGF. Purpose: This study aims to investigate the effects of AG shells and SH on bFGF expressions and blood vessel counts within the bone healing process. Methods: Twenty four male Wistar rats were divided into three groups, namely: a control group (C), a treatment group was administered with blood cockle shell (AG), and a treatment group with blood cockle shell and golden sea cucumber (AG+SH). Defects were made on their femurs measuring half the diameter of a circular, no. 018. bur These rats were subsequently sacrificed on day 7 after surgery. The expressions of bFGF were measured by means of IHC technique, while the number of blood vessels was quantified using HE technique. The resulting data was subjected to statistical analysis using an Anova test followed by an LSD test (p < 0.05). Results: The one-way Anova test results combined with those of an LSD test showed there to be significant differences in bFGF expressions and blood vessel counts between the control group (K) and the treatment group (AG) as well as between the treatment group (AG) and the treatment group (AG+SH). Conclusions: A combination of Anadara granosa shell and Stichopus hermanni can increase the expression of bFGF and the number of blood vessels on day 7 during the bone healing process in Wistar rats.

Background: Porosity is an important property that must be possessed by scaffold due to its role in new bone growth. Hydroxyapatite is a scaffold material with a composition resembling that of bone that can be synthesized from cockle shell (Anadara granosa). Purpose: This research aimed to determine the effects of various HA-TCP concentrations (wt%) derived from cockle shell synthesis on scaffold porosity. Methods: HA-TCP was synthesized from cockle shells using a hydrothermal method at 200o C with a 12-hour sintering process period. An XRD test was subsequently carried out to determine the composition of hydroxyapatite (HA) and tricalcium phosphate (TCP) compounds. Eighteen scaffold samples (n=6) were then produced using a freeze dry method and divided into three groups, namely; Group 1 (K1) treated with 5% HA-TCP, Group 2 (K2) treated with 25% HA-TCP and Group 3 (K3) treated with 50% HA-TCP. Thereafter, a scaffold porosity test was conducted using liquid displacement method. Scaffold porosity was observed by means of an SEM image. A One-Way ANOVA test was subsequently performed, followed by an LSD Post-Hoc test (p <0.05). Results: The results of the XRD test showed that the percentage of HA was 51.5%, while TCP was 16.8%. The porosity of the scaffolds was within the range of 67.24% - 80.17%. The highest porosity was found in Group 1, while the lowest occurred in Group 3. There were significant differences in all groups. Conclusion: The concentration of HA-TCP derived from the synthesis of cockle shells affects the porosity of scaffold. The lower the concentration of HA-TCP, the higher the scaffold porosity.

Background: Porous scaffold is one type of biomaterial primarily employed as a bone substitute material which demonstrates superior osteoconductive and osteointegrative properties than solid scaffold since it can stimulate and accelerate the growth of new tissue. For the purposes of this study, porous scaffold was produced using hydroxyapatite-tricalcium phosphate (HA-TCP) powder derived from a synthesis of blood cockle (Anadara granosa) shells and gelatin. Purpose: The aim of this study was to reveal the effects of the percentage of gelatin in HA-TCP scaffolds derived from 6- and 12-hours sintering processes involving blood cockle shells on porosity. Methods: HA-TCP powder was derived from a synthesis of Anadara granosa shells using a hydrothermal method at 200oC with sintering periods of 6 and 12 hours. A XRD test was subsequently conducted to reveal the compositions of HA-TCP powder. The 24 scaffold samples (n=6) employed were manufactured using a freeze dry method before being divided into four groups, namely; Group 1 using 25% HA-TCP powder (a six-hour sintering process) combined with 20% gelatin, Group 2 using 25% HA-TCP powder (a six-hour sintering process) combined with 10% gelatin, Group 3 using 25% HA-TCP powder (a twelve-hour sintering process) combined with 20% gelatin; and Group 4 using 25% HA-TCP powder (a twelve-hour sintering process) combined with 10% gelatin. A scaffold porosity test was subsequently carried out using a liquid displacement method. A one-way ANOVA test was performed using SPSS, followed by a Post-Hoc LSD (p<0.05). Results: The statistical results for scaffold porosity were within the range of 67.21 -77.51%. The highest porosity was found in Group 3, while the lowest was in Group 4. Significant differences were also present in all groups. Conclusion: Variations in the percentage of gelatin can affect the porosity of HA-TCP scaffolds derived from 6-and 12 hours sintrering processes blood cockle shells. The smaller the percentage of gelatin, the higher the porosity.

The prevalence of dental caries in Indonesia is still high. One of the dental caries treatments is direct restoration. Biomaterial, often used as a restorative material, is glass ionomer cement which has a silica content of 35%. Silica is found in Penaeus monodon shells which have been a waste of production. This research aims to study the characteristic of Penaeus monodon shell powder extracts as candidates for dental materials restoration. The research sample used was Penaeus monodon shell powder extract which was then carried out by a depigmentation process by mixing acetone 1:10 (w/v) ≤ 20 hours. Samples were tested with the XRD test (x-ray diffraction). SEM assessment was performed to evaluate the morphology of the particle. Data were analyzed using Mann-Whitney. The result demonstrated a significant silica content in Penaeus monodon shell powder extract before and after the depigmentation process with a p-value of 0,00 (p0,05). The depigmentation process can decrease silica content in Penaeus monodon shell powder extract. There was a different comparison of silica content in Penaeus monodon shell powder extract before and after depigmentation as a candidate for dental materials restoration.
