Oral And Maxillofacial Radiology
Oral and maxillofacial radiology, also known as dental and maxillofacial radiology, is the specialty of dentistry concerned with performance and interpretation of diagnostic imaging used for examining the craniofacial, dental and adjacent structures. Oral and maxillofacial imaging includes cone beam computerized tomography, multislice computerized tomography, magnetic resonance imaging, positron emission tomography, ultrasound, panoramic radiography, cephalometric imaging, intra-oral imaging (e.g. bitewing, peri-apical and occlusal radiographs) in addition to special tests like sialographs. Other modalities, including optical coherence tomography are also under development for dental imaging. Training United States Oral or dental maxillofacial radiology is one of nine dental specialties recognized by the American Dental Association. To become an oral and maxillofacial radiologist one must first complete a dental degree and then apply for and complete a postgraduate cou ...

Computer Tomography Skull
A computer is a machine that can be programmed to Execution (computing), carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as Computer program, programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the Computer hardware, hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devi ...

Occlusion (dentistry)
Occlusion, in a dental context, means simply the contact between teeth. More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest. Static occlusion refers to contact between teeth when the jaw is closed and stationary, while dynamic occlusion refers to occlusal contacts made when the jaw is moving. The masticatory system also involves the periodontium, the TMJ (and other skeletal components) and the neuromusculature, therefore the tooth contacts should not be looked at in isolation, but in relation to the overall masticatory system. Anatomy of Masticatory System One cannot fully understand occlusion without an in depth understanding of the anatomy including that of the teeth, TMJ, musculature surrounding this and the skeletal components. The Dentition and Surrounding Structures The human dentition consists of 32 permanent teeth and these are distributed between the ...

Master Of Science
A Master of Science ( la, Magisterii Scientiae; abbreviated MS, M.S., MSc, M.Sc., SM, S.M., ScM or Sc.M.) is a master's degree in the field of science awarded by universities in many countries or a person holding such a degree. In contrast to the Master of Arts degree, the Master of Science degree is typically granted for studies in sciences, engineering and medicine and is usually for programs that are more focused on scientific and mathematical subjects; however, different universities have different conventions and may also offer the degree for fields typically considered within the humanities and social sciences. While it ultimately depends upon the specific program, earning a Master of Science degree typically includes writing a thesis. The Master of Science degree was first introduced at the University of Michigan in 1858. One of the first recipients of the degree was De Volson Wood, who was conferred a Master of Science degree at the University of Michigan in 1859. Al ...

Canadian Dental Association
The Canadian Dental Association (CDA; French: ''Association dentaire canadienne'') is a non-profit professional association representing Canada's 18,000 dentists. Headquartered in Canada's capital city Ottawa, the CDA serves its members and the public by managing key oral health issues on their behalf and by coordinating dental health awareness programs across the nation. CDA is actively involved with lobbying and advocacy initiatives and uses its leadership role to communicate to the public and the government the profession's concerns regarding managed dental care. History The CDA was founded in 1902. Deborah Stymiest of Fredericton was elected as its first female president in 2008. CDA Seal Program The CDA Seal is a symbol to help consumers know which oral health benefit claims made by a manufacturer have been independently reviewed and are supported by scientific evidence. The seal is designed to help the public and dental professionals make informed choices. It is based on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Postgraduate
Postgraduate or graduate education refers to academic or professional degrees, certificates, diplomas, or other qualifications pursued by post-secondary students who have earned an undergraduate ( bachelor's) degree. The organization and structure of postgraduate education varies in different countries, as well as in different institutions within countries. While the term "graduate school" or "grad school" is typically used in North America, "postgraduate" is often used in countries such as (Australia, Bangladesh, India, Ireland, New Zealand, Pakistan, South Africa, and the UK). Graduate degrees can include master's degrees, doctoral degrees, and other qualifications such as graduate certificates and professional degrees. A distinction is typically made between graduate schools (where courses of study vary in the degree to which they provide training for a particular profession) and professional schools, which can include medical school, law school, business school, and oth ...

Radiologist
Radiology ( ) is the medical discipline that uses medical imaging to diagnose diseases and guide their treatment, within the bodies of humans and other animals. It began with radiography (which is why its name has a root referring to radiation), but today it includes all imaging modalities, including those that use no electromagnetic radiation (such as ultrasonography and magnetic resonance imaging), as well as others that do, such as computed tomography (CT), fluoroscopy, and nuclear medicine including positron emission tomography (PET). Interventional radiology is the performance of usually minimally invasive medical procedures with the guidance of imaging technologies such as those mentioned above. The modern practice of radiology involves several different healthcare professions working as a team. The radiologist is a medical doctor who has completed the appropriate post-graduate training and interprets medical images, communicates these findings to other physicians by m ...

Specialty (dentistry)
In the United States and Canada, there are twelve recognized dental specialties in which some dentists choose to train and practice, in addition to or instead of general dentistry. In the United Kingdom and Australia, there are thirteen. To become a specialist requires training in a residency or advanced graduate training program. Once a residency is completed, the doctor is granted a certificate of specialty training. Many specialty programs have optional or required advanced degrees such as a master's degree, such as the Master of Science (MS or MSc), Master of Dental Surgery/Science (MDS/MDSc), Master of Dentistry (MDent), Master of Clinical Dentistry (MClinDent), Master of Philosophy (MPhil), Master of Medical Science (MMS or (MMSc); doctorate such as Doctor of Clinical Dentistry (DClinDent), Doctor of Medical Science/Sciences (DMSc), or PhD;or medical degree: Doctor of Medicine/ Bachelor of Medicine, Bachelor of Surgery (MD/MBBS) specific to maxillofacial surgery and som ...

Optical Coherence Tomography
Optical coherence tomography (OCT) is an imaging technique that uses low-coherence light to capture micrometer-resolution, two- and three-dimensional images from within optical scattering media (e.g., biological tissue). It is used for medical imaging and industrial nondestructive testing (NDT). Optical coherence tomography is based on low-coherence interferometry, typically employing near-infrared light. The use of relatively long wavelength light allows it to penetrate into the scattering medium. Confocal microscopy, another optical technique, typically penetrates less deeply into the sample but with higher resolution. Depending on the properties of the light source ( superluminescent diodes, ultrashort pulsed lasers, and supercontinuum lasers have been employed), optical coherence tomography has achieved sub-micrometer resolution (with very wide-spectrum sources emitting over a ~100 nm wavelength range). Optical coherence tomography is one of a class of optical tom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sialogram
Sialography (also termed radiosialography) is the radiographic examination of the salivary glands. It usually involves the injection of a small amount of contrast medium into the salivary duct of a single gland, followed by routine X-ray projections. The resulting image is called a sialogram. Sialography has largely been replaced by sialoendoscopy and cross-sectional imaging, such as CT, MRI and ultrasonography. Uses This procedure is indicated when there is recurrent swelling and pain on the face but ultrasound has not revealed any problems. If Sjögren syndrome (also known as Sicca syndrome, an autoimmune disease that affects the lacrimal and salivary glands, causing reduced tears and saliva production) is suspected, this procedure is useful. Besides, when interventional proecudre is planned such as stone removal from salivary ducts or dilatation of the strictures in the salivary gland, this procedure is also indicated. However, for those who are pregnant, with allergy to iod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitewing
Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor. Teeth appear lighter because less radiation penetrates them to reach the film. Dental caries, infections and other changes in the bone density, and the periodontal ligament, appear darker because X-rays readily penetrate these less dense structures. Dental restorations (fillings, crowns) may appear lighter or darker, depending on the density of the material. The dosage of X-ray radiation received by a dental patient is typically small (around 0.150 mSv for a full mouth series), equivalent to a few days' worth of background environmental radiation exposure, or similar to the dose received during a cross-country airplane fl ...
