Removal of mineral constituents or salts from bone or bone tissue. Demineralization is used as a method of studying bone strength and bone chemistry.
Decrease, loss, or removal of the mineral constituents of bones. Temporary loss of bone mineral content is especially associated with space flight, weightlessness, and extended immobilization. OSTEOPOROSIS is permanent, includes reduction of total bone mass, and is associated with increased rate of fractures. CALCIFICATION, PHYSIOLOGIC is the process of bone remineralizing. (From Dorland, 27th ed; Stedman, 25th ed; Nicogossian, Space Physiology and Medicine, 2d ed, pp327-33)
A tooth's loss of minerals, such as calcium in hydroxyapatite from the tooth matrix, caused by acidic exposure. An example of the occurrence of demineralization is in the formation of dental caries.
A hard thin translucent layer of calcified substance which envelops and protects the dentin of the crown of the tooth. It is the hardest substance in the body and is almost entirely composed of calcium salts. Under the microscope, it is composed of thin rods (enamel prisms) held together by cementing substance, and surrounded by an enamel sheath. (From Jablonski, Dictionary of Dentistry, 1992, p286)
A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principle cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.
Therapeutic technique for replacement of minerals in partially decalcified teeth.
A test to determine the relative hardness of a metal, mineral, or other material according to one of several scales, such as Brinell, Mohs, Rockwell, Vickers, or Shore. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
Substances that inhibit or arrest DENTAL CARIES formation. (Boucher's Clinical Dental Terminology, 4th ed)
Diagnostic tests conducted in order to measure the increment of active DENTAL CARIES over a period of time.
Production of a radiographic image of a small or very thin object on fine-grained photographic film under conditions which permit subsequent microscopic examination or enlargement of the radiograph at linear magnifications of up to several hundred and with a resolution approaching the resolving power of the photographic emulsion (about 1000 lines per millimeter).
Fluorides, usually in pastes or gels, used for topical application to reduce the incidence of DENTAL CARIES.
Dental caries involving the tooth root, cementum, or cervical area of the tooth.
The hard portion of the tooth surrounding the pulp, covered by enamel on the crown and cementum on the root, which is harder and denser than bone but softer than enamel, and is thus readily abraded when left unprotected. (From Jablonski, Dictionary of Dentistry, 1992)
Localized destruction of the tooth surface initiated by decalcification of the enamel followed by enzymatic lysis of organic structures and leading to cavity formation. If left unchecked, the cavity may penetrate the enamel and dentin and reach the pulp.

Xenogenic demineralized bone matrix: osteoinduction and influence of associated skeletal defects in heterotopic bone formation in rats. (1/35)

Demineralized bone matrix (DBM) was ectopically implanted in 36 male Wistar rats. In 18 of the animals a bone defect in the femoral condyles was also created: the left was filled with DBM and the right was left empty as a control. The animals were killed after 2, 4 and 6 weeks and new bone was histologically evaluated, comparing ectopic bone formation with or without distant bone injury. Results showed: (1) osteoinductivity of xenogenic DBM, and (2) earlier mineralization of ectopically implanted DBM in the group with associated skeletal injury. Our results show that xenogenic bone matrix acts as an osteoinductive material and that skeletal injury improves osteogenesis at distant sites.  (+info)

The correlation between immune rejection and osteoinduction of allogeneic bone grafting. (2/35)

OBJECTIVE: To evaluate the relationship between the immune rejection and the osteoinductive potential of bone allograft. METHODS: Allogeneic and syngeneic fresh bone, autolyzed antigen-extracted bone, bone matrix gelatin and demineralized bone matrix were implanted into the muscle of mice, and immunological tests, histological observation and alkaline phosphatase assay were performed. RESULTS: Three and 6 weeks after implantation, all kinds of allogeneic implants activated immune rejection, among them, fresh bone induced the most vigorous immune rejection and bone matrix gelatin caused the weakest response. Allogeneic autolyzed antigen-extracted bone, bone matrix gelatin and demineralized bone matrix inhibited proliferation of the lymphocytes in vitro and bone matrix gelatin had the most powerful inhibiting effect. Both allogeneic and syngeneic autolyzed antigen-extracted bone, bone matrix gelatin, and demineralized bone matrix induced heterotopic osteogenesis in vivo and bone matrix gelatin had the best osteoinductive capacity. CONCLUSION: There is a negative correlation between immune rejection to bone allograft and osteoinductive capacity of the graft.  (+info)

Demineralized bone matrix, bone morphogenetic proteins, and animal models of spine fusion: an overview. (3/35)

Preclinical investigations on the use of bone morphogenetic proteins (BMP) in the spine have yielded promising results. This has led to the preliminary introduction of these growth factors in controlled clinical trials. Initial data made available suggest that these differentiating factors will play a major role in the treatment of spinal disorders in the future. This article reviews key preclinical studies and their results that formed the basis for introduction into clinical trials. Non-primate and non-human primate models of spine fusion with BMP are reviewed objectively, and important issues regarding carrier, dose, and site of implantation are discussed. Finally, exciting new gene therapy research is discussed, with comments made on its applicability for the future.  (+info)

In vitro release of vancomycin from vancomycin-loaded blood coated demineralised bone. (5/35)

In vitro and in vivo studies have demonstrated the possibility that cancellous bone could be used as a carrier of antibiotics for local delivery. However, the release of antibiotics from the loaded cancellous bone is too rapid and uncertain. We hypothesised that demineralisation of cancellous bone would increase the amount of antibiotic adsorbed, and coating of the freeze-dried antibiotic-impregnated cancellous bone with bio-compatible material would prolong antibiotic release. Bovine cancellous bone blocks of equal size were demineralised using a 0.5 N HCl solution and loaded with vancomycin solution under vacuum. The loaded bone blocks were then freeze-dried. To obtain a bio-compatible coating, the vancomycin-impregnated bone blocks were soaked in fresh human venous blood for 3 h. The release of impregnated antibiotic from the bone blocks was evaluated in phosphate-buffered saline and foetal bovine serum. It was found that significantly larger amounts of vancomycin were adsorbed into the demineralised bone blocks than into the un-demineralised blocks. The blood coating was found to increase the duration of vancomycin release from the blocks. With demineralisation and blood coating, the blocks eluted vancomycin higher than therapeutic concentration for a 5-week period.  (+info)

Efficacy of contained metaphyseal and periarticular defects treated with two different demineralized bone matrix allografts. (6/35)

The efficacies of two different allografts, Grafton (demineralized bone matrix [DBM] in a glycerol carrier) and Orthoblast (DBM in a reverse thermal poloxamer carrier) were examined from cases involving periarticular fractures. Demographic, perioperative, and outcome data for patients with periarticular fractures who underwent a prospectively designed protocol for bone grafting were compiled, with 15 cases using Orthoblast and 13 using Grafton. A successful graft was defined as healing on the first graft attempt without complications. Healing was determined by radiographic studies and clinical evaluation. The successful graft rates of Orthoblast and Grafton were 15/15 and 9/13, respectively.  (+info)

Evidence for a serum factor that initiates the re-calcification of demineralized bone. (7/35)

The present studies show for the first time that demineralized bone re-calcifies rapidly when incubated at 37 degrees C in rat serum: re-calcification can be demonstrated by Alizarin Red and von Kossa stains, by depletion of serum calcium, and by uptake of calcium and phosphate by bone matrix. Re-calcification is specific for the type I collagen matrix structures that were calcified in the original bone, with no evidence for calcification in periosteum or cartilage. Re-calcification ceases when the amount of calcium and phosphate introduced into the matrix is comparable to that present in the original bone prior to demineralization, and the re-calcified bone is palpably hard. Re-calcified bone mineral is comparable to the original bone mineral in calcium to phosphate ratio and in Fourier transform infrared and x-ray diffraction spectra. The serum activity responsible for re-calcification is sufficiently potent that the addition of only 1.5% serum to Dulbecco's modified Eagle's medium causes bone re-calcification. This putative serum calcification factor has an apparent molecular mass of 55-150 kDa and is inactivated by trypsin or chymotrypsin. The serum calcification factor must act on bone for 12 h before re-calcification can be detected by Alizarin Red or von Kossa staining and before the subsequent growth of calcification will occur in the absence of serum. The speed, matrix-type specificity, and extent of the serum-induced re-calcification of demineralized bone suggest that the serum calcification factor identified in these studies may participate in the normal calcification of bone.  (+info)

Demineralized bone alters expression of Wnt network components during chondroinduction of post-natal fibroblasts. (8/35)

OBJECTIVE: The Wnt family of secreted proteins, their receptors (Fzd proteins) and antagonists (secreted Fzd-related proteins, or Sfrp) regulate chondrocyte differentiation and chrondrogenesis during embryonic development. Here, the hypothesis that the Wnt regulatory network contributes to chondrocyte differentiation of post-natal cells was tested in an in vitro model of chondroinduction by demineralized bone powder (DBP). DESIGN: Human dermal fibroblasts (hDFs) were cultured in porous, three-dimensional (3D) collagen sponges with or without chondroinductive DBP. In some experiments, lithium chloride (LiCl), an agonist of the Wnt/beta-catenin signaling pathway, was added to the culture media. Sponges were cultured for intervals (0.5-21 days) before processing for molecular, histologic, and biochemical analyses. Expression of wnt, fzd, and sfrp genes was characterized by semi-quantitative RT-PCR. Fibroblasts' contacts with DBP were documented by histology. Accumulation of proteoglycan in extracellular matrix was evaluated by histology (metachromasia in toluidine blue-stained sections) and quantitative immunoassay (chondroitin 4-sulfate ELISA). RESULTS: Expression of 15 wnt, fzd, and sfrp family members was detected in hDFs by RT-PCR. A subset of those genes (wnt2b, wnt5b, wnt10b, fzd6, fzd7) showed altered expression in hDFs exposed to DBP for 3 days. wnt and fzd gene expression was not altered before hDFs contacted the DBP within the collagen sponge. Human DFs cultured in plain collagen sponges and treated with LiCl accumulated significantly more metachromatic matrix than NaCl-treated controls on day 10, and showed a trend towards increased matrix chondroitin-4 sulfate content. CONCLUSIONS: These data suggest that changes in Wnt signaling contribute to chondroinduction of post-natal fibroblasts by DBP. This is the first evidence that Wnt components, which are essential regulators of pre-natal chondrocyte differentiation, may also influence post-natal chondrocyte differentiation induced by DBP.  (+info)

But silicas most important use to man is as a nutrient.. Silica promotes the synthesis of the proteins collagen (Type 1) and elastin. Collagen is an abundant protein in mammals, making up the majority of connective tissue like cartilage, tendons, ligaments, gums and skin. Elastin is a stretchy protein, important for healthy skin, lungs and arteries (especially the aorta). Silica also promotes stronger thicker hair, stronger nails, and stronger bones. Although silica only makes up a tiny proportion of bone, its important for promoting re-calcification of bone and speeding healing of fractures. As we age the silica content of our tissues decreases, especially for post-menopausal women ...

A unicameral bone cyst, also known as a simple bone cyst, is a cavity filled with a yellow-colored fluid. It is considered to be benign since it does not spread beyond the bone. Unicameral bone cysts can be classified into two categories: active and latent. An active cyst is adjacent to the epiphyseal plate and tends to grow until it fills the entire diaphysis, the shaft, of the bone; depending on the invasiveness of the cyst, it can cause a pathological fracture or even destroy the epiphyseal plate leading to the permanent shortening of the bone. A latent cyst is located away from the epiphyseal plate and is more likely to heal with treatment. It is typically diagnosed in children from the aged 5 to 15. Although unicameral bone cysts can form in any bone structure, it is predominantly found in the proximal humerus and proximal femur; additionally, it affects males twice as often as females. Most unicameral bone cysts do not cause any symptoms and are discovered as accidental findings on ...

Das Bone Morphogenetic Protein 2 (BMP2) gehört zur TGF-beta Superfamilie und findet seinen Fokus in der osteogenen Aktivierung und in der Anwendung bei der Frakturheilung. Es wird angenommen, dass weitere, bisher unbekannte Verbindungen existieren, die die BMP2-Signalübertragung und die osteogene Aktivität verbessern und somit zu einer verbesserten klinischen Wirksamkeit von BMP2 führen. Für den Stickstoffoxid (NO)-Signalweg ist bereits bekannt, dass im endothelialen Kontext eine Verbindung zum BMP2-Signalweg existiert. Ziel dieser Arbeit war es daher, eine Verbindung zwischen dem NO- und BMP2-Signalweg bezüglich der Regulierung des BMP2-abhängigen Signalwegs und der Osteoinduktion aufzuzeigen. Dies erfolgte durch Anwendung von Inhibitoren (LNAME, ODQ und LY83583) und Aktivatoren (L-Arginin, Deta NONOate, SNAP und YC-1) des NO-Signalwegs, in Kombination mit BMP2. Eine mögliche Verbindung zwischen dem BMP2- und NO-Signalweg, über eine Protein Kinase A (PKA) Brücke, wurde durch die ...
Consider that you may have a card putting 15dBm (32mW) into a 2.2dBi antenna (on the AP), and thatyour card probably has an effective 2dBi gain antenna on it. Operating at 2.4GHz, at 1m, thereis 41dB of path loss between the two units. At 2m, youll have another 6dB of path loss, for 47dB.So the signal leaves at 17dBm (from the AP), you lose 41dB due to LOS (Line of Sight) path lossat 1m, and the signal arrives at the antenna in your laptop at perhaps -24dBm, and is raisedto -22dBm by the antenna.This is quite close to the maximum signal level of 802.11g ...

Several studies demonstrated that the use of graft material has better clinical results for the treatment of intrabony defects. The purpose of this study is to compare the clinical and radiographic efficacy of alloplast (Biphasic calcium phosphate) and demineralized freeze-dried bone allograft (DFDBA) in treatment of periodontal intraosseous defects. A split mouth study was conducted in 20 subjects diagnosed with chronic periodontitis presenting atleast two intrabony defects in either arch. One quadrant (Site A) received alloplast (Biphasic calcium phosphate) and the contralateral defect (Site B) received DFDBA. The results of study showed that clinically Site B (DFDBA) showed greater reduction in pocket depth and gain in clinical attachment level than site A (Biphasic calcium phosphate), however it was not statistically significant. Site A (Biphasic calcium phosphate) showed slightly more gingival marginal recession than Site B (DFDBA). Radiographically Site B (DFDBA) showed greater bone fill ...

Many bone cysts will eventually heal without the need for treatment and wont cause long-term problems - particularly unicameral bone cysts in children, which will usually disappear by the time they stop growing.. If a bone cyst does not get better, or if treatment is recommended to help reduce the risk of a fracture, several options may be available.. For example, steroid medication can be injected into the bone to encourage the cyst to heal. If this doesnt help, surgery may be needed to drain the fluid and fill the hole with chips of bone.. There is a significant chance of the cyst recurring after treatment, so you may need to have regular X-rays for a few years afterwards to look for signs of the condition returning..

dBm - dB referenced to 1 milliwatt. To convert into an equivalent voltage level, the impedance must be specified. For example, 0 dBm into 600 ohms gives an equivalent voltage level of 0.775V, or 0 dBu; however, 0 dBm into 50 ohms, for instance yields an equivalent voltage of 0.24 V. Since modern audio engineering is concerned with voltage levels, as opposed to power levels in the early years of telephone, the convention of using a reference level of 0 dBm is academic. But in the A/V industry, many people still refer to 0.775Vrms (600 r) as 0 dBm, which should be more accurately called 0dBu. ...

This retrospective study evaluated the efficacy of minimally invasive surgery to control cyst progression for active unicameral bone cysts (AUBC) by intracystic methylprednisolone injection, percutaneous curettage, and autogenous bone marrow grafting. From May 2010 to May 2017, patients diagnosed with AUBC who underwent percutaneous double-needle intracystic methylprednisolone injection, percutaneous curettage, and autogenous bone marrow grafting were retrospectively reviewed. Recurrence was defined by modified Neer scale score. Patients were followed up regularly, and previous imaging findings were compared to evaluate treatment efficacy. The 26 patients (17 boys, 9 girls, mean age, 9.4 ± 3.1 years) were followed up for a mean 45.1 months (range, 24-82 months). Follow-up consisted of clinical evaluation and radiographic review. Twenty patients (77%) achieved latent disease stage after the first treatment, while six (23%) achieved it after the second treatment. Postoperative pathological fracture
Tyrannosaurus ( or , meaning tyrant lizard) from the Greek words τυράννος (tyrannos, meaning tyrant) and σαύρος (sauros, meaning lizard), is a genus of theropod dinosaur. The species Tyrannosaurus rex (rex meaning king in Latin), commonly abbreviated to T. rex, is a fixture in popular culture. It lived throughout what is now western North America, with a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the last two million years of the Cretaceous Period, 67 to 65.5 million years ago. It was among the last non-avian dinosaurs to exist prior to the Cretaceous-Tertiary extinction event.. Like other tyrannosaurids, Tyrannosaurus was a biped carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small, though unusually powerful for their size, and bore two clawed digits. Although other theropods rivaled or exceeded Tyrannosaurus rex in ...

A method by which immune responses to cortical bone grafts and other substrates (e.g., cement, IPN, etc.) can be minimized and at the same time graft osteoinductive potential can be improved, and improved graft substrate materials are disclosed. The method of the invention provides new types of bone grafts that incorporate into host bone more thoroughly and more rapidly, eliminating long-term complications, such as fracture, non-union, infection, and rejection. In the method of the invention, bone grafts or other substrates are modified to have an osteoinductive surface modification that the recipients body will accept as its own tissue type and therefore will not reject or otherwise cause to fail. The osteoinductive surface modification comprises a biopolymer matrix coating that is seeded with periosteal cells that have been previously harvested either from the graft recipient or from an allogenic or xenogenic donor source.

Demineralized bone matrix fibers and a demineralized bone matrix composition are provided. The demineralized bone matrix fibers have an average fiber length in the range from about 250 μm to about 2 mm and an aspect ratio of greater than about 4. The demineralized bone matrix composition includes demineralized bone matrix fibers and a biocompatible liquid in an amount to produce a coherent, formable mass. The formable mass retains its cohesiveness when immersed in a liquid. Methods for making the demineralized bone matrix fibers and composition are also provided.
From the figure above, we can learn that the first set of data is resulted from the four channel CWDM network without use of the RA, while the second utilizes the RA. In order to check whether the Raman amplifier benefits the CWDM network, we can take the data of 100km CWDM transmission through singlemode fiber (SMF) as an example. The power penalty of the transmission with a RA are separately -34.4 dBm, -34.2 dBm, -33.2 dBm and -32.3 dBm. It is 0.3 dBm better than the power penalty of the transmission without a RA, at least. Except that, we can also learn that the CWDM network with a RA can transmit the signals through the SMF at lengths up to 150m without any repeater stations, while the network without the RA cannot.. Conclusion. The Raman amplifier is an ideal alternative to the repeater in CWDM network, for intensifying the CWDM signals and extending the CWDM network reach. By using the Raman amplifier, the loss budget of the CWDM network can be increased, which finally achieves a longer ...

  • Resorption or wasting of the tooth-supporting bone (ALVEOLAR PROCESS) in the MAXILLA or MANDIBLE. (
  • The bacteria found in plaque (the sticky substance on teeth) produce acids that lead to demineralization of the tooth surface, and ultimately contribute to periodontal disease. (
  • In fact, research has shown quite consistently that hydroxyapatite toothpaste is just as or even more effective than fluoride toothpaste in preventing demineralization, reducing tooth sensitivity, and even treating early decay. (
  • Compared with natural H5, the new peptide adsorbed more strongly to the tooth surface, killed more bacteria, inhibited their adhesion and protected teeth from demineralisation. (
  • Causes demineralisation of the tooth surfaces like enamel (outermost layer of teeth). (
  • McInnes bleaching agent does decrease the microhardness of enamel by causing enamel demineralization and GC Tooth mousse used in the study causes an increase in the microhardness of bleached enamel by maintaining a high gradient of calcium and phosphate ions at the enamel subsurface. (
  • While gingivitis only affects tissue, periodontitis silently eats at the bone around the tooth, usually without any warning or discomfort. (
  • Too much demineralization without enough remineralization to repair the enamel layer leads to tooth decay . (
  • Tooth movement by orthodontic treatment is characterized by remodeling changes in the periodontal ligament, alveolar bone, and gingiva. (
  • The diet high in sugars and acidifying substances, psychological stress that triggers parafunctional behaviors, the reduced intake of fiber-rich foods or alkalizing substances, together with other factors, contribute to demineralization of the tooth enamel. (
  • Dental implants also help preserve the tooth-supporting bone in your jaw that naturally deteriorates when even one tooth is lost. (
  • Increased serum ALP and calcium level could be often associated with the alveolar bone loss and tooth loss in type 2 diabetes mellitus with periodontitis among the South Indian population. (
  • Tooth enamel is the best for this purpose due to the highest degree of mineralization (97-99% of tooth enamel mass is hydroxyapatite compared to up to 70% in bones and dentine) and absence of metabolism and remodeling, which may act as confounding factors when EPR dosimetry with bone and dentine is concerned teeth) to a regional or generalized involvement of primary or secondary teeth. (
  • Fluoride treatments can prevent tooth decay and reverse the first stage of decay, called the demineralization stage. (
  • Cheese helps stimulate saliva to flush away cavity-producing bacteria, minimizes tooth demineralization, and rebuilds lost enamel. (
  • Tooth cleaning is usually accomplished by the non-surgical technique of scaling, sometimes called "root debridement. (
  • Special tips are also available to clean composite or porcelain tooth restorations, titanium implants, or areas of demineralization (enamel loss) on your teeth. (
  • This affects the tissue that supports the teeth and if this is left untreated the bone in the jaw may decay. (
  • Celery protects teeth by producing saliva which neutralizes acid that causes demineralization and cavities. (
  • Before recommending treatment or performing any pocket reduction treatment, the dentist will perform thorough visual and x-ray examinations in order to assess the condition of the teeth, gums and underlying bone. (
  • Gum disease is a persistent inflammation of the gums and bones of the teeth. (
  • Rather, when your body becomes acidic due to a wrong lifestyle, it tries to restore the balance by leaching minerals from your bones and teeth, which starts de-mineralisation, causing cavities. (
  • As mentioned above, if this level is disturbed, the body withdraws minerals from your teeth and bones, in an attempt to achieve acid-alkaline balance. (
  • Researchers have developed a novel coating which protects teeth from demineralisation. (
  • According to the Linus Pauling Institute, Calcium is the most common mineral in the human body, with about 99% of total body calcium residing in bones and teeth. (
  • It's understood that regular servings of this dairy product prevent the demineralization of teeth, and will help boost the remineralization process. (
