The drive for development of new and novel oral biomaterials has never been more important with many people using oral biomaterials today and seeing their benefits in restoring and improving their oral health for a more enjoyable lifestyle.
The unique properties of biomaterials such as titanium Tizirconia ZrO2 and various polymeric materials have made them materials of choice in oral health: dental implants, oral and maxillofacial surgery, and even regenerative medicine. Oral biomaterials research today is an exciting and intensive multidisciplinary area that encompasses contributions from a wide range of fields from professional dentistry to biology, chemistry, physics, material science, and engineering.
In the course, you will learn about the special properties and benefits of biomaterials including, titanium and titanium alloys, zirconia and other alloys, ceramics, and modern composites. You will gain insights of the practical use of these biomaterials in different aspects of dentistry and clinical implications. You will realize how contemporary dentistry is about unifying synthetic materials to living tooth and bone tissues.
And lastly, you will be introduced to procedures and testing methods used to test significant mechanical properties of biomaterials in the research laboratory. You can get recognition for completion of the course by obtaining a Course Certificate. Great to have sessions on recent material advancements in Dentistry!

Examples include cataract formation, skin reddening erythemaand sterility. Also referred to as non-stochastic effects Stochastic Effects The effect may potentially occur following any amount of exposure there is no threshold.
Examples include cancer and genetic defects. X-rays are very short wavelength electromagnetic radiation. Doubling your distance from the X-ray tube reduces your exposure by a factor of four Tripling your distance from the X-ray tube reduces your exposure by a factor of nine!

What determines the ability of plain films to differentiate between various substances and tissues? What are the limitations of a single radiographic view? In addition to the five categories of density, computed tomography CT technology is able to detect what differences? What are Hounsfield units? The radiology examination that provides the required data with the least amount of radiation, expense, and need for extraneous follow-up supports the best practices of patient care. Although radiologic examinations have become vital adjuncts to clinical problem-solving, they should not replace the process of developing a coherent problem list generated by the patient's concerns, medical history, and physical examination.
The ordering physician critically contributes to the process of radiology interpretation not only by asking the right questions of individual patients, but by selecting the right examination and effectively communicating the questions that need to be answered by imaging to patients, technologists, and radiologists. The physician should request only those studies that will influence management, continually filter the results in the context of the patient, and ensure appropriate follow-up of abnormal and incidental findings.
Practitioners must not only balance risks and benefits of a specific study for an individual patient but also be mindful of the impact of clinical decision-making on populations of patients even if the test is readily available. Ever-expanding technologies will always require the expertise of radiologists in interpretation; however, physicians must have a basic understanding of various imaging modalities, their limitations, risks, and relative costs in order to select the right examination for a specific patient.
Framework for utilization of radiology. Chapter will review principles of patient safety—risks of contrast, radiation exposure, and gadolinium. Subsequent chapters will cover the application of specific imaging modalities.

Molina and Chest Radiology 3 Definition of Radiology Radiology is a medical specialty using medical imaging technologies to diagnose and treat patients.
Can you identify the modality used? High radiation. Nuclear Medicine Physiological imaging, great for specific questions. Ultrasound US Relatively inexpensive, and no radiation.
Highly dependent on patients body size and US operator. Magnetic resonance imaging MRI Relatively expensive, no radiation, not fast.Used 3 shape trios
Unmatched ability to contrast healthy tissue from disease. In hyper-acute renal failure, the creatinine hasnt risen yet. Decreased urine output or anuria is acute renal failure regardless of the creatinine. Remember first do no harm! Non-contrast studies can often be quite helpful. Correctly labeled with patients name, MR, and the date of the study? Technically adequate?Uses sound waves to produce image, transmitted Sending out and listening for echoes Internal architecture Dynamic, US can not penetrate air or bone Operator dependent.
Uses X-rays to produce an image, transmitted Cross sectional imaging No superimposition of structures Requires computer manipulation of images.
Forms of Diagnostic Imaging Nuclear Scintigraphy Uses gamma rays to produce an image, emitted from the patient Radioactive nuclide given IV, per os, per rectum etc. Abnormal function, metabolic activity, abnormal amount of uptake Poor for anatomical information. Forms of Diagnostic Imaging Magnetic Resonance Imaging Uses a strong magnetic field and radiofrequency waves to image structures No ionizing radiation Hydrogen protons water Cross sectional imaging Great for soft tissue.
Forms of Diagnostic Imaging Radiation Therapy Uses radiation to treat and palliate neoplastic and some benign diseases Cobalt Linear Accelerators Must have special training. Form of EM radiation All forms move at the speed of light Vary in energy and wavelength They penetrate matter Can cause fluorescence of some atoms Can expose film Can cause biological damage.
The X ray Tube Cathode is the electron source Tungsten filament Negatively charged concave cup around filament Focal spot Thermonic emission current applied wire heats up and electrons escape.
The X ray Tube Anode is the target which electrons strike Tungsten target Stationary Anode in large block of copper lots of heat Used in portable units. Rotating Disc rotates which spreads electrons around the target thus less heat build up www. The X ray Tube Note the various components and remember what they do.
The surface of the anode is angled Allows for better cooling and maintains detail X rays on cathode side more intense How would this be used in practice? Learn more about Scribd Membership Home.
