Abstract: Dental implant surface technologies have been evolving rapidly to enhance a more rapid bone formation on their surface and hold a potential to increase the predictability of expedited implant therapy.Numerous surface modification approaches have been developed for all classes of dental implants to modulate biological responses and improve the osseointegration and primary stability. Hence, Implant threads should be designed to maximize the delivery of optimal favorable stresses while minimizing the amount of extreme adverse stresses to the bone implant interface. In addition, using of biomaterial coating of implant surface for the enhancement of bone formation has been achieved through the modulation of osteoblasts adhesion and spreading that induced better stability and more implant surface contact area.The aims of the study are : 1. Evaluation of titanium implant osseointegration by the modification of thread design and I or coating its surface by Flaxseed.2. Evaluate the new surface modification of titanium implant, histologically, mechanically and radiographically.Materials and methods : One hundred and twenty eight commercially pure titanium (CpTi) screws were implanted in rabbit tibiae. Implants were divided as follows : 1. Dual - threaded group (32 implants). 2. Single - threaded coated with grinded flaxseed group (32 implants).3. Single - threaded with central groove (32 implants).4. Single - threaded (control) group (32 implants).Histological, mechanical and radiographical analysis were performed for all implants after each healing periods (2,4,6 and 8) weeks.Results : 1. Dual - threaded implant illustrated the highest mean value in thread width and removal torque, and it showed mature bone at 8 weeks.2. Grooved implant illustrated close opposing threads. 3. Coated implant illustrated highest mean value in osteoblast cell count and showed a proliferating cartilage zone that later on degenerated and replaced by bone.Conclusion : The present results conclude that each modified implants shows a different benefits whether a modification of the implant surface mechanically (dual or grooved thread) or by coating the implants with Flaxseed.

Abstract: The objectives of this study was to evaluate the effect of addition of Multi - Wall Carbon Nano ubes(MWCNTs) of different concentration (0.05 mg/mL - 1, 0.25 mg/mL - 1, 0.5 mg/mL - 1and 1 mg/mL - 1) with on either (dimethyl sulphoxide DMSO and distilled water DW) on tooth enamel. It is intended to evaluate enamel microhardness in (Kg.m - 2) and enamel thermal conductivity before and after the application of (MWCNTs).Ninety mandubular first premolar were prepared for this study. They were divided into two groups. The first group contains 54 sample to measure the microhardness of the enamel. To overcome the teeth curvature in microhardness measurement, the position of indenter were optimized to coincide linear buccal surface. The second group contains 36 sample to measure the thermal conductivity of the enamel were prepared by cutting enamel part in triangle form with a base of 7. 5 mm , height of 9. 5 mm and thickness of 2 mm according to the requirements of the Fourier’s law by abrasive disk.The results enamel microhardness showed that a significant increase in the enamel microhardness and enamel thermal conductivity for groups 0.05 mg/mL (group B) , 0.25 mg/mL (group C ) , 0.5 mg/mL (group D ) and 1 mg/mL (group E ) compared with control group (group A ) in DW media and DMSO media. The results showed a significant increase in the enamel microhardness and enamel thermal conductivity for polished samples compared with unpolished samples in DW media and DMSO media. DMSO media increases the enamel microhardness and enamel thermal conductivity more effectively than DW media. Scanning electron microscope showed a significant deposition of MWCNTs in the depth of the enamel exceeding the surface layer. The polished specimens had more deposited MWCNTs compared with non - polished specimens. However, the nano dimensions with conjunction with pre - chemical treatment enabled the MWCNTs to penetrate and settle down inside the enamel.The final conclusion highest mean value obtained was 1 mg/mL (group E ) in the enamel microhardness and enamel thermal conductivity suspension in DW media and DMSO media.

Abstract: Background : Bones are rigid organs that constitute part of the endoskeleton of vertebrates. They support and protect the various organs of the body, produce red and white blood cells and store minerals. Bone tissue has been shown to contain numerous cell - to - cell signaling peptides called growth factors. These growth factors are thought to have important regulating effects for bone remodeling and bone healing. Several growth factors are expressed during fracture repair. of these, vascular endothelial growth factor (VEGF), is of particular interest because of its ability to induce neovascularization (angiogenesis). The responses to exogenous VEGF observed that a slow - release formulation of VEGF, applied locally at the site of bone damage, may prove to be an effective therapy to promote human bone repair. N - acetyl glucosamine is a monosaccharide, which are the derivatives of carbohydrates, it helps the body in making several other chemical agents which are used in the formation of bones, muscles and cartilages.N - acetylglucosamine is very effective in providing support for the skeletal system of the humans, and may provide strength to the ligaments and joints, and the skin remains fresh and glowing. Aims of study1. To identify role of local exogenous application of vascular endothelial growth factor and application of N - acetyl - D glucose amine as a biomaterial in bone healing.2. To analyze the expression of Vascular endothelial growth factor, tissue non specific ALP and bone matrix protein (collagen - 1) by immunohistochemistry in created bone defect after application with different biomaterials in a rat model. Materials and MethodsIn this experimental study fifty four male Albino rats, weighting (300 - 400) gram, aged (6 - 8) months were used and maintained under control conditions of temperature, drinking and food consumption. The animals were subjected for a surgical operation of medial sides of both tibial bone ( right side was considered as experimental site ,while left be the control one). The animals were divided into following groups according to the applicable growth factors.A. Contol group the bone defect treated with 1?m of normal saline and its number represented the all number of the following experimental groups as the left side of each animal considered to be the control.B. Experimental group includes ? Group I contains (18) rats, the bone defect treated with 1?ml of Vascular endothelial growth factor. ? Group II contains (18) rats the bone defect treated with 1?ml of Nacetyl D - glucosamine.? Group III contains (18) rats, the bone defect treated with 1?m combination of (VEGF& N - acetyl D - glucosamine).Every single group composed of 18 rats that studied in three periods 3,7,10 days (6 rats for each period). Histologic and immunohistochemical evaluation for VEGF, alkaline phosphatase and collagen type 1 were carried for all animals.Results : A. For Histological findings An early apposition of osteoid tissue was detected in VEGF group. Osteoblast, osteocyte and osteoclast cells count were demonstrated to be with high mean value in VEGF group followed by N - acetyl Dglucosamine group in periods 3,7,10 days post operative of bone defect.Inflammatory phase as first step in bone healing was detected in all study groups at 3 day, and combination group records highest value in the mean of inflammatory cell count in comparisum to others. Finally thestudy demonstrated that exogenous VEGF/ N - acetyl D - glucosamine has a direct effect on osteoblastic activity.B. For Immunohistochemical findings The present result showed positive expression of VEGF by bone marrow stromal cells, adipocytes, mesenchymal stem cells, precursor endothelial cells, and bone cells include osteoblasts and active osteocytes in different periods in all groups but in different score. Therefore, our primarily data provide evidence that VEGF activity is essential for appropriate bone formation and mineralization in response to injury. At day 3, bone marrow stromal cells in combination group records highVEGF expression, VEGF group is the second. At 7 and 10 day VEGF group records a highest VEGF expression in comparisum to other groups. The data showed a high expression for ALP during the formative stages of bone in all groups except combination group shows the lowest count for positive cells that expressed ALP.the present results showed that at day 3, bone marrow stromal cells in VEGF and N - acetyl D - glucosamine group records high collagen type I expression. Conclusion : the study demonstrated that low application of VEGF / Nacetyl D - glucosamine could be an effective therapeutic for bone injuries, these data are promising for a possible future clinical usage.
