Abstract

Autogenous bone graft is the gold standard for bone defects treatment, however due to their limitation and the donor site morbidity may caused many surgeons use a xenograft type of bone grafting to cope the problem. Demineralized Freeze Dried Bone Xenograft (DFDBBX) which contains of growth factors, have a good biocompatibility. The aim of this study is observed the difference in bone healing processes between DFDBBX and Bovine Bone Hydroxyapatite Xenograft (BBHAX). Bicortical bone defects were created in the mandibular corpus of 30 New Zealand White Rabbits. The groups were divided into 3 groups which the first group were treated with DFDBBX into the hole and the negative control group was left perforated. The other group was treated with BBHAX. All group were evaluated after second and fourth weeks to count the ammount of osteoblast, osteoclast cells, Collagen-1 (Coll-1) and alkalin phosphatase (ALP). The second week of observation showed a significant difference of mean 12,45, SD 2,97 (p<0,05) in osteoblast cells. In Coll-1 showed with mean 13,2 SD 2,68 (p<0,05). The result of ALP showed with mean 14,6 SD 2,70 (p<0,05). In the the fourth week observation showed increased of osteoclast cells with mean 7,043, SD 2,77 (p< 0,05) and for Coll-1 with mean 17,6, SD 2,30 (p< 0,05). DFDBBX showed more effective in treating bone defects of mandible of new zealand white rabbits in second week of observation.

Abstract

Inflammation and alveolar bone resorption are indications of periodontal disease, which is a chronic inflammatory illness caused by bacterial colonization that damages the soft and hard structures that support the teeth. In response to persistent tissue injury and chronic inflammation, fibroblasts also play a role in the synthesis and maintenance of extracellular matrix, cell proliferation, and cell differentiation. Fibroblasts play a crucial part in the healing of wounds. Phenols, alkaloids, flavonoids, and tannins are some of the health-promoting components found in water hyacinth. As a result, plant extracts must be tested first, one of which is the viability test in accordance with the requirements and materials in the field of dentistry. The viability test is a cell-based test that is often used for screening compounds to determine whether the test compound has an effect on cell proliferation or has a direct cytotoxic effect that leads to cell death. The goal of this study is to figure out what concentration of water hyacinth leaf extract can keep human gingival fibroblast cells alive for 24 hours. Primary cell cultures from human gingiva were extracted and placed in a 96-well microplate. For 24 hours, water hyacinth leaf extract at concentrations of 1 mg/ml, 0.5 mg/ml, 0.25 mg/ml, 0.25 mg/ml, 0.125 mg/ml, 0.0625 mg/ml, 0.0312 mg/ml, 0.0156 mg/ml was administered to each well in the microplate. After 24 hours of incubation, the MTT assay was carried out by adding MTT solution. The optical density of formazan was measured using an ELISA reader at a wavelength of 590 nm, and viability was calculated using the viability formula. Starting at 0.125 mg/ml, 0.0625 mg/ml, 0.0312 mg/ml, and 0.0156 mg/ml, the vitality of human gingival fibroblast cells was good. In the treatment group, the greatest vitality of human gingival fibroblast cells was 0.0156 mg/ml (75.98%).

Abstract

The consumption rate of Monosodium Glutamate (MSG) in Indonesia has increased every year. Uncontrolled use of MSG in Indonesia for a long period of time can cause toxic effects on the body. The free glutamate content produced by MSG can affect the work of the immune system, especially in the innate immune system and cause oxidative stress. To determine the effect of exposure to Monosodium Glutamate (MSG) on the viability of monocyte cells. This study is a laboratory experimental in vitro with a post test only control group design. A total of 10cc of peripheral venous blood was isolated using the ficoll gradient centrifugation method. The results of monocyte cell isolates were exposed to Monosodium Glutamate (MSG) according to groups. Group I: negative control, group II: monocyte cells + MSG 3%, group III: monocyte cells + MSG 6%, group IV: monocyte cells + MSG 9%. Subsequently incubated for 24 hours at 37 °C in 5% CO2. Then the viability test was carried out using trypan blue staining. Monocyte cell viability calculations were carried out under an inverted microscope with a magnification of 400x per 100 cells. The data obtained were analyzed statistically using the one-way Anova test followed by the LSD test. The average viability in each group was obtained as follows, monocyte cell viability in the control group was 63%, group II was 47%, group III was 45% and group IV was 35%. There is an effect of exposure to Monosodium Glutamate (MSG) on the viability of monocyte cells with the most significant effect being the 9% MSG concentration with an average viability of 35%.The consumption rate of Monosodium Glutamate (MSG) in Indonesia has increased every year.

Abstract

The use of biomaterial such as bone graft material is highly needed in oral and maxillofacial surgery to overcome bone defect that happened due to various reasons. One of the bone graft that widely used is bovine hydroxyapatite (BHA). BHA is produced by means of deproteinizing by a high-temperature heating process so that inorganic material of bone is left where the bone architecture is preserved. This material has osteoconductive property because it induces osteoblast activity and new bone formation. DFDBX is a bone graft derived from bovine bone which has undergone the demineralization process and subsequently frozen. Then, it will be exposed to hydrochloric acid until the bone matrix component-related collagen fibril called BMPs. Runt-Related Transcription factor 2 (RUNX2) is a transcription factor which is needed for osteoblast differentiation and it is first detected at preosteoblast. Osteocalcin is exerted during the last stage of differentiation, started at the early stage of mineralization. Objectives to compare the expression of RUNX2 and Osteocalcin following the application of DFDBX and BHA to the bone defect. Methode 30 male New Zealand White Rabbit, 6- months old, 3-3,5kg, divided into 3 groups comprising of 10 animals each, bone defect is created on each animal model. On group 1, DFDBX is applicated, BHA is on group 2, and control group with no graft application. After 2 weeks and 4 weeks following the animal model is terminated to retrieve a bone specimens for Immunohystochemistry examination. Result The expression of RUNX2 following the application of DFDBX and BHA showed a significant difference at week 2 but not showed at week 4. This research also found that the expression of osteocalcin did not show a significant difference at week 2 but showed a significant difference at week 4. Conclussion This study demonstrate that bone healing process in DFDBX group is more effective than BHA.

Abstract

Reconstruction of extensive bone tissue damage is a treatment with complication. Because moving the autologous tissue such as bone graft can cause complications that causes problems in the repair of extensive tissue damage so, the principle of tissue engineering (stem cells, bioreactor / growth factor, and scaffold) is used as an alternative to reconstruct damage to the tissue because it has many advantages. The combination of hADMSC and chitosan scaffold, is expected to trigger osteoinduction that can be expressed by osteogenic markers such as phosphorus levels in blood serum. To prove osteoinduction in a combination of Human Adiposed Derived Mesenchymal Stem Cell (hADMSC) and chitosan scaffold using blood serum phosphorus levels. This study used 12 groups with 5 sample each. Groups 1 to 4 were the negative control group at day 1,3,7, and 14. While groups 5 to 8 were the positive control group at day 1,3,7, and 14. Groups 9 to 12 were treatment groups at day 1,3,7, and 14. In the negative control group bone was only removed, in positive control group, bone was removed and chitosan scaffold was added, and in treatment group, bone was removed then, hADMSC and chitosan scaffold combination was added . Blood collection will be carried out in each group for examination of phosphorus levels in the blood serum. There were differences in phosphorus levels in blood serum in each group even though statistically there were only significant differences on day 14. The combination of hADMSC and chitosan scaffold caused a significant change in blood serum phosphorus levels on day 14 which means it triggers osteoinduction.
