Calcium sulfate Essays

Calcium sulfate (CS) (CaSO4) occupies a unique position among bone regenerative materials. It is used in clinical practice for long time than most currently available biomaterials and is widely recognized as a biocompatible material with applications in bone regeneration. It has the advantage that it is available and inexpensive (Thomas & Puleo, 2009). The ‘‘gypsum’’ or CS is a mineral consisting of calcium sulfate dehydrate (CaSO4.2H2O). It must be screened before use in medical practice for impurities

INTRODUCTION Gypsum is scientifically named calcium sulfate dehydrate with the formula (CaSO4.2H2O). It is known to be a white powdery substance that is a naturally occurring mineral. The main form of calcium sulfate dehydrate used in dentistry is named calcium sulfate hemihydrate with the formula (CaSO4)2.H2O. Gypsum is mainly used for dental restorations and applications to replicate the patients’ oral cavity. Dies and models are created using the 5 gypsum products; impression plaster (Type 1)

Calcium (Ca++) The total amount of calcium circulating in the blood is small (9.0-10.5 mg/dl) and half of the total amount is bound to albumin a plasma protein. In humans, calcium ranks fifth after oxygen, carbon, hydrogen, and nitrogen. Intracellular calcium is located primarily in the mitochondria. Approximately 99% of calcium is contained in bones and teeth as calcium hydroxyapatite an inorganic compound that contributes to bone rigidity (McCance, K. L., & Huether, S. E. 2013). Calcium

The saponification (a reaction in making soap) process is a base (usually NaOH or KOH) hydrolysis of triglycerides to make salt (soap) and glycerol. Alkalis such as Sodium carbonate and Sodium hydroxide are used to neutralize the fatty acid and convert it to a salt. The molecules crystallize differently depending on the base used. NaOH produces a harder bar while KOH is used more frequently for liquid soaps. In some cases, Lithium soaps are formed and produce much harder soaps. There are four

1. Structure of drug calcium carbonate , commonly known as limestone , limestone , stone powder which have : Molecular formula: CaCO3 Molecular Weight: 100.09 2. Physical properties White solid, odorless, odorless. There are two forms of amorphous and crystalline. Crystalline type can be divided into orthorhombic and hexagonal crystals, columnar or diamond. The relative density is 2.71 to 825-896.6°C, and it decomposes into calcium oxide and carbon dioxide at about 825°C. Melting point 1339°C, melting

INTRODUCTION Fracture is defined as discontinuation of bone meaning the two bones is separated. The range of broken bones can be from a thin crack to a complete break. A crack (not only a break) in the bones is also known as fracture. It can be fracture of crosswise, lengthwise, in several places or into many pieces. Typically, it happens when the bone was subjected to impact of more force or pressure than it can withstand. Commonly, broken bone can happen in childhood and mature and late adulthood

Knee Dislocation It’s painful to see someone suffering from a dislocated knee, but even more so if it happened to you Although knee dislocations are considered rare, and only accounts for about less than 0.5 percent of joint dislocations, it could happen to anyone. Women, such as female athletes, are more at risk of having knee dislocations due to their body structure. While women have wider and shapely hips than men, these add more stress on their knees making them more prone to knee injuries

Learn more about the effects that collagen drinks can have on TMJ disorders. The temporomandibular joint (TMJ) is a hinge connecting your jaw to the temporal bones at the sides and base of your skull. Your temporomandibular joint allows you to move your jaw up and down and from side to side, so you can chew, yawn, and talk. Difficulty chewing or clicking jaw when opening your mouth The temporomandibular joint is one of the most complex joints in the body because it combines hinge and sliding motions

replaced more slowly. Osteoporosis is more likely to develop if you have poor nutrition or do not get enough calcium or vitamin D. Other lifestyle factors can also play a role.

Fibrodysplasia ossificans progressiva is one of the rarest and most disabling disease known to mankind. The disease progression is caused when connective tissue such as; muscle, tendons, or ligaments are slowly replaced by bone. Eventually, the additional bone formation outside the skeleton will constrict movement and imprison the body. The literature on fibrodysplasia ossificans progressiva is sparse, which could account for the extremely high rate of misdiagnoses of the disorder. An important

The bones are important components that provide support to the human body. Bones are composed of calcium, phosphorus and magnesium. Osteoporosis is a disease characterized by low bone mass and deterioration of bone tissue. This leads to increased bone fragility and risk of fracture. Two essential cells are involved in the daily turnover of the bone, osteoblast cells and osteoclast cells. although over activity of the osteoclast cell leads to osteoporosis, There is no single cause of osteoporosis

The right balance of calcium is needed to properly build and maintain bones. Too little calcium can result in lost bone mass (Griffin). This is where calcium supplements could come into play. The purpose of calcium supplements is to balance out calcium absorption by making up for the calcium that is not obtained from food (Griffin). Calcium should primarily be acquired through food, but if a diet is lacking calcium, a supplement may be recommended by a physician. Proper calcium absorption can only

Tap water, the water humans drink daily has always been corrosive and yet not most people are aware of that. What is the water being consume daily really made up of? Can the corrosion in the water have irreversible damage on a human body? After doing a little bit of research the actual question is, how can we make our water less corrosive or even better how can we make it 100% pure? As most of the citizens in town know, our water has already been used a few times from other cities which means our

or both. Calcium and phosphate are two essential minerals for normal bone formation. Throughout youth, the body uses these minerals to produce bones. Calcium is an essential component for proper functioning of the heart, brain, and other organs. The body reabsorbs calcium that is stored in the bones to maintain blood calcium levels and also to keep those critical organs functioning properly and continually. If calcium intake is not sufficient or if the body does not absorb enough calcium from the

Bone is one of the most important connective tissues found in the body. It is very intricate, complex and specialised. In addition to providing mechanical support, bone also acts as a reservoir for minerals, mainly calcium and phosphate. The tissue in itself is highly dynamic as it possesses a self-remodelling nature that allows the bone remodel itself depending upon the mechanical loading it encounters, moreover bone can also self-regenerate to a large extent that allows repairing of tissue without

Chapter One Introduction 1.1. Introduction: Nutrition refers to the processes by which a living organism ingests digests, absorbs and excretes nutrients. Nutrition as a clinical area is primarily concerned with the properties of food that build sound bodies and promote health. a good nutrition for a person is essential to good healthy body and prevents diseases and other health problems, the individual should be provided with knowledge about nutrition and the body nutritional requirement

Osteoporosis also known as porous bones is defined as the loss of bone mass in which the density and quality of bones are reduced, leading to bone fragility and susceptibility to fractures. It is known as a ‘silent disease’ as the loss of bone occurs without symptoms and progressively. Bone is made of tough, elastic fibers and materials and it is a living tissue that makes up and resorbs bone. Osteoblasts are the cells that make the matrix of the bone while osteoclasts are cells that resorb bone

Fibrodysplasia Ossificans Progressiva which is sometimes referred to FOP is a very rare genetic disorder in which bones grow uncontrollably to the point of causing disability (Fibrous Dysplasia). As one of the rarest and most disabling diseases, FOP causes bone to form in and over muscles, tendons, ligaments, and other connective tissues (What is FOP). Bridges of this extra bone develops across joints which causes immobility (What is FOP). These bridges also create a second skeleton that imprisons

Compression sleeve for heel spurs The heel bone or calcaneus bone which is the largest bone in the foot experience an abnormal growth is a scenario where heel spurs occur. The area where the plantar fascia pulls away from the heel, form calcium deposit. This situation is common to those who are flat footed but in some cases, a person with high arches experience heel spurs. In most cases, a heel spur measures quarter of an inch in length that makes it not visible to the naked eye. While plantar fasciitis

What Causes Bone Spurs? A bone spur (also called osteophyte) is a bone growth that forms on bone or near a cartilage or tendon. This extra bone develops as the body repairs itself in response to constant pressure, friction, or stress over a bone, usually in the spine, the shoulder, hand, hip, knee, or foot. What causes bone spurs? Here are the common causes why people develop extra bone over bone. 1. What Causes Bone Spurs? • Osteoarthritis Osteoarthritis is a degenerative bone condition that affects
