Abstract

ABSTRACTBackground: Alveolar bone resorption can occur after tooth extraction. One source of bone scaffold material is hydroxyapatite and tricalcium phosphate (HA-TCP). The shell of Anadara granosa can be synthesized to be HA-TCP. Hyaluronic acid, which is widely contained in Stichopus hermanni, can stimulate endothelial progenitor cells for the healing process. Purpose: This research aims to prove the Effectivity of scaffold from Anadara granosa shell-Stichopus hermanni on blood vessel counts after tooth extraction. Methods: The sample in this study was male Wistar rats divided into four study groups randomly. Each group consists of 6 rats. Extraction was carried out on the mandibular first incisor, then was given gelatin as a placebo in the control group, treatment groups given scaffold from Anadara granosa shells (AG), and scaffold combination from Anadara granosa shells-Stichopus hermanni with concentrations of 0.4%-0.8%. (AGSH1-AGSH2). Development of HA-TCP synthesized from Anadara granosa combined with Stichopus hermanni extract for biomedical scaffolds using the freeze-dried method. Observations were made three days after tooth extraction. Data analysis has used one-way ANOVA followed by Tukey HSD (p<0.05). Results: The results of the ANOVA test followed by the HSD-Tukey test showed a significant difference between C (7.33±1.51) and AGSH1 (11.50±1.38), AGSH2 (21.17±1.94), AG (9.33±1.63) and AGSH1 with AGSH2, but between AG and, AGSH1 no significant differences.Conclusions: Combination scaffold from Anadara granosa shell and Stichopus hermanni 0.8% effectively increased blood vessel counts after tooth extraction.

Abstract

Background: People usually used non steroid anti-inflammation drugs (NSAID) such as aspirin in chronic inflammation treatment. However, using NSAID at long term therapy will cause many effects such as nausea and vomiting. Sardinella longiceps oil, on the other side, is reported as an alternative treatment for anti-inflammation since it is natural and also contained eicosapentaenoid acid (EPA) and decohexaenoic acid (DHA). Thus, it may reduce paw oedema. Purpose: The aim of this study was to know anti-inflammation effects of Sardinella longiceps oil against paw oedema of Wistar rats induced by 1% carrageenan. Methods: The samples of this research were 32 Wistar rats which were divided into four groups, in group 1, the rats were given aquadest; in group 2, the rats were given aspirin; in group 3, the rats were given 1 ml Sardinella longiceps oil; in group 4, the rats were given 1.5 ml Sardinella longiceps oil. All of the rats, nevertheless, were given intraplantar induction of 1% carrageenan into the paw of rats to induce the inflammation condition. Results: All data were tested with normality test. The normal data were then analyzed with Homogenity of Variances and also ANOVA test which result showed significant differences. The data which showed significant differences were tested again with LSD test. result then showed that group given 1 ml Sardinella longiceps oil and group given 1.5 ml Sardinella longiceps oil had no significant differences from group given aspirin, but there were significant differences between group given 1 ml Sardinella longiceps oil and group given 1.5 ml Sardinella longiceps oil, and also between group given 1.5 ml Sardinella longiceps oil and group given aquadest. Conclusion: Sardinella longiceps oil could reduce paw oedema in Wistar rats induced with 1% carrageenan.Latar belakang: Penggunaan obat anti-inflamasi non steroid (OAINS) seperti aspirin sering digunakan dalam pengobatan inflamasi kronis. Namun penggunaan OAINS dalam jangka waktu panjang akan menyebabkan efek samping seperti mual dan muntah. Di sisi lain, minyak Sardinella longiceps, dilaporkan dapat digunakan sebagai alternatif anti-inflamasi karena selain alami, juga terdapat kandungan eicosapentaenoid acid (EPA) and decohexaenoic acid (DHA) yang dapat mengurangi edema pada telapak kaki. Tujuan: Tujuan dari penelitian ini adalah mengetahui efek anti-inflamasi minyak Sardinella longiceps pada edema telapak kaki tikus Wistar yang diinduksi karagenan 1%.

Abstract

Background: Alveolar bone damage is the most common case in dentistry. One way to fix the bone damage is by using bone graft. Anadara granosa shell is a potential bone substitute since it is rich in calcium which can be processed into hydroxyapatite. The addition of Sardinella longiceps oil rich in omega-3 can modulate inflammation, thus accelerating the healing process. Purpose: This study aimed to determine effects of application of Anadara granosa shell combined with Sardinella longiceps oil on osteoblast proliferation in the healing process of bone defects. Method: The subjects were 32 male rats type Wistar divided into 4 groups (n = 8). Making defect was performed on the right bone of the femurs with a half of the diameter of round Mcisinger® Germany bur sized 18. The first group (K) is a negative control group that was not given anything. The second group (AG) was given Anadara granosa pasta. The third group (AM10) was given Anadara granosa pasta combined with 10% Sardinella longiceps oil. And, the fourth group (AM30) was given Anadara granosa pasta combined with 30% Sardinella longiceps oil. Next, preparations and animal euthanasia were performed on the 7th day after the treatment. The number of osteoblasts then was measured after making preparations for HPA with Hematoxylin eosin staining (HE). Afterward, tabulation of data followed by statistical analysis of Anova and HSD Tukey was carried out. Result: The average number of osteoblasts in Groups K, AG, AM10, and AM30 was 19.00, 34.63, 33.50, and 38.50. The results of Anova test showed a significant difference (p<0.05). Similarly, the results of Tukey-HSD test also showed significant differences (p<0.05) between Group K and all other groups (AG, AM10, and AM30). Nevertheless, there were no significant differences between Group AG and Groups AM10 and AM30, as well as between Group AM10 and Group AM30. Conclusion: The application of the combination of Anadara granosa shell and Sardinella longiceps oil can not increase the proliferation of osteoblasts in the healing process of bone defects.

Abstract

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.

Abstract

Background: Bone grafts derived from Anadara granosa shells contain calcium carbonate that possesses bone-healing properties. The combination of Sardinella Longiceps fish oil, containing EPA and DHA, and Anadara granosa shells was assumed to regulate the number of osteoblasts-osteoclasts during the bone-healing process. Purpose: This study aimed to determine the effectiveness of Anadara granosa shell grafts, combined with Sardinella Longiceps fish oil, in the bone-healing process by observing the ratio of osteoblasts-osteoclasts in Rattus novergicus rats. Methods: The Wistar rat subjects (n = 25) were divided into five groups, namely: one untreated group (control), one group treated with bone grafts derived from Anadara granosa shells (P1), and the other three groups treated with a combination of Anadara granosa shells and Sardinella longiceps fish oil at concentrations of 10%, 20%, and 30% (P2, P3, and P4). Then, a wound equivalent in size to half the diameter of a round bur (±1.5mm) was intentionally inflicted on the right femur of all the subjects. The rats were subsequently sacrificed on day 14, their femur in the transversal side being cut before HE staining was completed. Thereafter, the ratio of osteoblasts to osteoclasts was measured by means of a light microscopy. The data was subsequently analyzed using one-way ANOVA. Results: The average number of osteoblasts in all research groups increased, viz: 9.420±0.8044 for control group (K), 12.080±0.79811 for group P1, 20.020±0.7190 for group P2, 25.940±0.7197 for group P3, and 36.280±0.9985 for group P4. Similarly, the number of osteoclasts in all groups subject to analysis also increased, namely: 1.73±0.098 for group K, 2.19±0.305 for group P1, 1.60±0.088 for group P2, 1.60±0.724 for group P3, and 1.80±1.302 for group P4. Moreover, the results of the One-way Anova test confirmed that there were no significant differences in osteoclasts between all research groups (p>0.05). The results of the one-way ANOVA and LSD tests confirmed there to be significant differences (p <0.05) between group K and other treatment groups (P1, P2, P3, and P4). Conclusion: The grafts derived from the combination of Anadara granosa shells and Sardinella longiceps gel can induce the production of osteoblasts, but not in the numbers necessary during the healing processin the femurs in Rattus novergicus rats.

Abstract

Background: Long bleeding time is a risk factor in dental treatment, especially in patients who consume aspirin or other antithrombotic drugs. Holothuria scabra (H. scabra) are mostly echinodermata and have been studied in Indonesia; they contain omega-3 and glycosaminoglycans, with an influence of an antithrombotic drug. Purpose: This study aimed to investigate the thrombocyte counts during the post-administration of aspirin and the H. scabra extract in Wistar rats (Rattus norvegicus). Methods: This study was true experimental with a post-test control group design. The sample consisting of 30 healthy male Wistar rats (R. norvegicus) with a bodyweight of 150–250 g was divided into three groups (n = 10). The rats in Group 1 were given sodium carboxymethyl cellulose (Na CMC). The rats in Group 2 were given aspirin, and the rats in Group 3 were given the H. scabra ethanol extract with a 25 mg/200 g dose as per their body weight (BW). Oral administration was given for seven days. The rats’ blood was taken on the eighth day. The amount of thrombocyte was measured using Wright’s stain methods. The analysis of variance (ANOVA) and the Least Significant Difference (LSD) tests were conducted for data analysis (p < 0.05). Results: The thrombocyte counts (179.00 ± 10.56) in aspirin administration were lower than those in H. scabra (265.00 ± 18.54) and control groups (334.17 ± 13.9), with a significant difference between the groups (p = 0.0001; p < 0.05). Conclusion: This study indicates that the oral administration of aspirin and H. scabra decreases thrombocyte counts, whereas the administration of aspirin reduces thrombocyte counts to levels lower than those in H. scabra in Wistar rats (R. norvegicus).

Abstract

Background: Post-extraction complications can cause alveolar bone resorption. Hydroxyapatite-tricalcium phosphate (HA-TCP) is one potential bone graft material that can be synthesized from Anadara granosa shell. Another biomarine, Stichopus hermanni, contains hyaluronic acid which can accelerate bone formation on the fourteenth day. Purpose: This study aims to prove the effectiveness of Anadara granosa shell-Stichopus hermanni granules in weaving bone formation fourteen days after tooth extraction. Methods: Twenty-five male Wistar rats were divided into five groups. Their lower left incisor was extracted with gelatin being administered to the control group (C) and granule scaffold derived from Anadara granosa (AG) shell and Anadara granosa shell-Stichopus hermanni at concentrations of 0.4%-0.8%-1.6% (AGSH1-AGSH2-AGSH3) to the treatment group. This study developed a HA-TCP synthesized from Anadara granosa combined with whole Stichopus hermanni to create granule scaffolds by means of a freeze-dried method. The jaw was removed on the fourteenth day post-tooth extraction. Observation of HPA involved the use of an Image Raster®. The resulting data was subjected to analysis by ANOVA and tukey-HSD tests (p<0.05). Results: Data showed the mean of C=0.157±0.078; AG=1.139±0.371; AGSH1=1.595±0.291; AGSH2=1.740±0.308; and AGSH3=1.638±0.286. Statistical analyses showed significant differences in the woven bone area (mm2) between C and the treatment groups AG;AGSH1;AGSH2; AGSH3; and between AG and the AGSH2 groups. Conclusions: Scaffold granules from Anadara granosa shells and Stichopus hermanni effectively accelerate the bone formation process with the most effective being Stichopus hermanni at a concentration of 0.8%.

Abstract

Pendahuluan: Resin akrilik heat cured (HC) merupakan pilihan utama bahan sebagai basis gigi tiruan. Hidroksiapatit (HAP) adalah molekul kristalin yang sudah banyak digunakan di kedokteran gigi. Penelitian terdahulu membuktikan bahwa HAP mampu mengurangi monomer sisa pada resin akrilik HC, yang akan mengurangi juga porositas resin akrilik tersebut. Berkurangnya porositas resin akrilik, diharapkan akan meningkatkan kekuatan mekanik resin akrilik tersebut. Tujuan penelitian menganalisis pengaruh penambahan hidroksiapatit terhadap porositas dan compressive strength resin akrilik HC. Metode: Jenis penelitian eksperimental laboratoris. Sampel penelitian 20 resin akrilik HC berbentuk silindris (6x3mm), dibagi menjadi 4 kelompok. Kelompok kontrol (tanpa penambahan HAP), kelompok HAP 2%, kelompok HAP 5%, dan kelompok HAP 10%. Permukaan sampel diteliti menggunakan SEM untuk porositasnya. Penghitungan compressive strength sampel menggunakan Universal Testing Machine (load cell 300kg/mm2). Hasil: Uji one-way ANOVA dan Tukey-HSD menunjukkan perbedaan signifikan (p<0,05) antara kelompok kontrol (90±13,5MPa) dengan 5%HAP (105±4,3MPa) dan 10%HAP (113±10,2MPa), begitu pula antara 2%HAP (96±8,4MPa) dengan 10%HAP. Uji SEM menunjukkan tidak adanya reaksi kimia antara HAP dan resin akrilik HC. Tampak pula bercak putih tersebar tidak merata pada permukaan sampel akrilik di kelompok-kelompok perlakuan. Bercak putih ditemukan meningkat sebanding dengan peningkatan konsentrasi HAP, dengan diameter yang semakin besar. Simpulan: Penambahan HAP pada basis resin akrilik HC mampu menurunkan tingkat porositas dan meningkatkan nilai compressive strength. Penurunan tingkat porositas meningkat seiring dengan penambahan HAP. Compressive strength yang paling tinggi didapatkan pada basis resin akrilik heat cured dengan penambahan 10% hidroksiapatit.Kata kunci: Compressive strength, uji SEM, resin akrilik heat cured, hidroksiapatit. ABSTRACT Introduction: Heat-cured acrylic resin has been commonly used as a denture base, whereas hydroxyapatite (HAP) is a crystalline molecule widely used in the field of dentistry. Previous research has been proofed that HAP could reduce the residual monomer of heat-cured acrylic resin, which will reduce the porosity level in advance, so it was expected for better mechanical properties. This research was aimed to analyse the effect of HAP addition towards the porosity level and compressive strength of heat-cured acrylic resin. Methods: An experimental laboratory research was conducted towards 20 cylindrical samples (6 x 3 mm) of heat-cured acrylic resins, which were divided into four groups: Control group (without HAP addition), 2% HAP addition group, 5% HAP addition group, and 10% HAP addition group. Compressive strength was tested using Universal Testing Machine (load cell of 300kg / mm2). Each sample surface porosity was observed using the scanning electron microscope (SEM). Results: One-way ANOVA and Tukey-HSD tests results showed significant differences (p < 0.05) between compressive strength in the control group (90 ± 13.5 MPa) compared to 5% (105 ± 4.3 MPa) and 10% HAP addition group (113 ± 10.2 MPa), significant differences were also shown between the 2% (96±8.4MPa) and 10% HAP addition group. SEM imaging showed that there was no chemical reaction between HAP and heat-cured acrylic resin. It showed uneven white spots in acrylic sample’s surface in all treatment groups. Those white spots were likely to be found more in the higher concentration of HAP, so did the diameter of white spots was also found more in the higher concentration. Conclusion: The addition of hydroxyapatite to the base of heat-cured acrylic resin can reduce the level of porosity and increase the compressive strength value.
