What are the disadvantages of bitewing radiographs?
Bitewing radiography is the most widely used clinical technique for caries detection. However, it has disadvantages such as patient discomfort. Variable levels of expertise of the operators often result in increased patient radiation dose due to the need for retakes [3].
What is the main limitation of bitewing radiography?
Bitewing radiography has a low sensitivity for the detection of early proximal lesions that extend only into enamel. This leads to the assumption that very early lesions (extending in the outer enamel histologically) will usually remain undetected.
What is the purpose of a bitewing radiograph?
Bitewing X-rays detect decay between teeth and changes in the thickness of bone caused by gum disease. Bitewing X-rays can also help determine the proper fit of a crown (a cap that completely encircles a tooth) or other restorations (such as bridges). It can also see any wear or breakdown of dental fillings.
Are dentin and enamel lesions visible on Bitewings?
In the bitewing digital images, 47 teeth presented visible radiolucency, circumscribed, in dentin under occlusal enamel (enamel-dentin caries lesions).
What is cervical burnout?
Cervical burnout appears as a radiolucent band around the necks of teeth and is more pronounced at the proximal edges. The X-ray photons overpenetrate or burn out the thinner tooth edge and create the radiolucent area that mimics cervical caries [26] (Figure 1).
What does a panoramic radiograph allow the dentist to see?
The panoramic X-ray provides the dentist with an ear-to-ear two-dimensional view of both the upper and lower jaw. The most common uses for panoramic X-rays are to reveal the positioning of wisdom teeth and to check whether dental implants will affect the mandibular nerve (the nerve extending toward the lower lip).
Why are they called Bitewings?
Why are they called that? The name “bitewing” refers to how the film — or sensor, in the case of a digital x-ray — is positioned in the mouth: The patient bites down on a little tab or wing that holds the apparatus in place.
How do you test for interproximal caries?
Conclusions: NILT examination has an appropriate sensitivity and diagnostic accuracy for detecting early interproximal caries lesions and can be considered as a method of choice for detecting caries without the use of ionizing radiation.
How do you explain the concept of caries control?
Caries care/management/control are actions taken to interfere with mineral loss at all stages of the caries disease [Nyvad and Fejerskov, 2015], including non-operative and operative interventions/treatments.
What causes a cone cut?
Cone cut may be caused by various reasons. The most common being the image receptor is not in line with the position indicating device (PID)/radiographic cone. Hence, the collimator which reduces the size and shape or cross-sectional area of the X-ray beam doesn’t completely exposes the film resulting in cone cut.
