What is periapical image?
A periapical x-ray or “PA film” will show one or two teeth in their entirety in one single image, right from the crown of the tooth which is the part exposed in the mouth to the very tips of the tooth roots located in the jawbone, as well as the surrounding bone supporting this tooth.
What is intraoral radiography?
There are two main types of dental X-rays: intraoral (meaning the X-ray film is inside the mouth) and extraoral (meaning the X-ray film is outside the mouth). Intraoral X-rays are the most common type of dental X-ray taken. Extraoral X-rays show teeth, but their main focus is the jaw and skull.
What is periapical radiograph?
Periapical X-rays show the whole tooth — from the crown, to beyond the root where the tooth attaches into the jaw. Each periapical X-ray shows all teeth in one portion of either the upper or lower jaw. Periapical X-rays detect any unusual changes in the root and surrounding bone structures.
What is periapical Radiolucency?
Periapical radiolucency is the radiographic sign of inflammatory bone lesions around the apex of the tooth. We determined the prevalence and predictors of periapical radiolucency in patients with cirrhosis and the association with systemic inflammation status and cirrhosis-related complications.
What is extraoral radiograph?
Abstract. Extraoral radiography means that both the image detector and the X-ray machine are placed outside the patient’s mouth. The X-ray source and the image detector have to be aligned in order to generate the desired image quality.
What is an extraoral radiograph?
What are Extraoral Radiographs? Like the first part of the name suggests, extraoral X-rays are made with the film outside the mouth. This type of X-ray still shows the teeth but can also provide important information about the jaw and skull.
What is a periapical Radiolucency?
Periapical radiolucency is the descriptive term for radiographic changes which are most often due to apical periodontitis and radicular cysts, that is, inflammatory bone lesions around the apex of the tooth which develop if bacteria are spread from the oral cavity through a caries-affected tooth with necrotic dental …
What is extraoral imaging?
Extraoral imaging. An image of the teeth and bones made by placing the film or cassette against the face or the head and projecting the x-rays from the opposite side.
What is transesophageal echocardiography?
Transesophageal Echocardiography (TEE) What is transesophageal echocardiography? Transesophageal echocardiography (TEE) is a test that produces pictures of your heart. TEE uses high-frequency sound waves (ultrasound) to make detailed pictures of your heart and the arteries that lead to and from it.
What is a Teetee test used for?
TEE is often used to provide information during surgery to repair heart valves, a tear in the aorta or congenital heart lesions. It’s also used during surgical treatment for endocarditis, a bacterial infection of the inner lining of the heart and valves.
