The panoramic image is a radiographic image that is taken using an extraoral receptor that is positioned outside of the mouth. It has become the standard extraoral image used to survey the patient’s oral and facial structures. The purpose of this image is to provide the dental radiographer an overall view of the maxilla and the mandible on a single projection. A dentist may use a panoramic image to evaluate the following: the dentition and supporting structures, impacted teeth, eruption patterns, growth and development, extent of large lesions, or trauma. (Iannucci, 2017) It may also be used to detect diseases, lesions and conditions of the jaw. Although this image is very useful it does not provide the clinician with as defined or sharp images as intraoral projection. Therefore, a pano. should not be used to diagnose caries, periodontal disease, or periapical lesions. (Iannucci, 2017) A diagnostic panoramic image should contain the following anatomic structure: dentition, teeth arranged in a smile like curve with all crowns and apices seen, the ramus and cervical spine, the nasal cavity and maxillary sinus, the body of the mandible, the …show more content…
The real image results when a structure lies between the receptor and the moving rotation center, it appears in the correct anatomic location. A double image occurs when the anatomic structure is behind the focal trough, an example of this is the hyoid bone, it appears twice on the resultant image. A ghost image occurs when an object is outside the focal trough and close to the x-ray source, it will resemble its true image and is found on the opposite side of the receptor. This can occur with metal objects like an earring or an anatomical structure like the ramus of the mandible. Often times the ghost image makes the resultant pano. image undiagnostic because it obscures important anatomical
For each client I collect several different assessments to help determine a diagnosis and individualized care plans. First, I start with assessing their oral hygiene routine and get a general idea of how important oral hygiene is to the client. After this, I preform an oral cancer screening to make sure all soft tissues appear normal. Next, I preform an assessment of the periodontal tissue color, contour and texture as well as recording a periodontal chart. Once all this information is gathered we take a look at all the information and determine a diagnosis. Then, we set goals and select appropriate interventions
Dental indices are important tools used in examinations to provide a numeric score that quantifies the magnitude of the disease measured.
Bitewing radiographs are an important adjunct to clinical examination and maybe necessary to help the clinician detect and diagnose caries (REF). However ionising radiation from x-ray exposure has the potential to cause malignancy in the patient and therefore clin...
3-D scanning has helped improve orthodontics a lot with finding the problem and being able to understand the problem better. Also it can help see everything in your mouth that a regular x-ray cannot see.
From my shadowing experience, I learnt that attention to detail is crucial when taking diagnostic images where the positioning of the patient and cooperating with the patient to produce accurate images is a large part of the job. A level photography has helped with my attention to detail which is why I better understood the preparations taken by the radiographer when processing accurate diagnostic
After the treatment and procedure is complete, patients leave with healthier, more beautiful teeth, giving them the confidence to ask someone out on a date or the confidence to smile on an important job interview. Dentistry is and has been for centuries, an important aspect of people’s ...
In order to really understand where medical imaging is currently at one must have a basic understanding of where it came from. Twenty years ago radiologist would read and dictate the images on film. They were able to accomplish this by holding the film up to light boxes. This method provided no way for the radiologist to interact or manipulate the images
Intraoral cameras are small cameras (about the size of a toothbrush), that allow your dentist to examine even the smallest details of your teeth. While your dentist is examining your mouth with this small camera, you will be able to watch the process on a monitor. You will see what your teeth look like up close and personal! Your dentist will be able to spot any cracks or broken fillings, and will allow you to see plaque deposits that you may be missing when you brush.
The ability to identify underlying issue and treat them more effectively is just one of the many benefits that are provided with this technology. It is becoming increasingly apparent that oral hygiene is an important part of a person’s overall health. Having technology that can aide a dental hygienist in providing better care to their patients is an advancement that can help propel dental hygiene into the future. Working together with the medical community and focusing on disease prevention, and overall wellness is the main reason that digital dental radiography has become so important in the dental hygiene
What are some of the elements involved in creating visual illusions? What role does culture play?
Initially she would perform the exams as learned in school, but now after finding something abnormal, she now does a more thorough check, especially on patients with previous history of cancer. This incident solidified her belief in early detection and proper documentation. By having the information in the patient’s chart Annette could refer back to it and follow up to see if anything has changed since the last visit. Most patients she sees do not have oral cancer but she is able to identify abnormalities and encourage the patient to have them checked to determine if they are precancerous.
The perspective of a deontologist with this dilemma may seem be a bit contradictory. This is
Image intensification is the process of converting x-ray into visible light. “Early fluoroscopic procedures produced visual images of low intensity, which required the radiologist's eyes to be dark adapted and restricted image recording. In the late 1940s, with the rapid developments in electronics and borrowing the ideas from vacuum tube technology, scientists invented the x-ray image intensifier, which considerably brightened fluoroscopic images” (Wang & Blackburn, 2000, np). We will explore the image-intensification tube, the various gain parameters associated with the tube, and the magnification mode of the image intensifier.
Images of human anatomy have been around for more than 500 years now. From the sketches created by Leonardo da Vinci, to the modern day Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) scan, images have played a great role in medicine. Evolution in medical imaging brought together people from various disciplines such as Biology, Physics, Chemistry and Mathematics, a collaboration which has further contributed to healthcare as a whole. Modern day imaging improves medical workflows by facilitating a non-invasive insight into human body, accurate and timely diagnostics, and persistence of an analysis.
An optical illusion can be a picture that appears to be an elephant with four legs, but when looking closer, a person is unable to count the legs, due to irregular lines. Another example of an optical illusion is the Hermann Grid Illusion, in which a grid with black boxes and gray lines appears to have black dots on the white circles. It does not, in reality,
