How do you fix a cone cut?
To correct a cone-cut error, the beam should be re-centered toward the area of non-exposure. Improper assembly of receptor holding devices can also cause cone-cuts. When assembling these devices, make certain that the entire receptor can be seen when looking through the indicator ring.
What causes cone cut dental X-ray?
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.
Can dental x-rays harm you?
Repeated exposure to dental X-rays may result in various health problems including head and neck tumors and various systemic problems.

What is a cone cut in X-rays?
Collimator cuts (also known as cone cuts) result from incorrect centering of the collimator over the receptor and its holder apparatus, if the latter is in use. Cone cuts are fairly common when tightly confined X-ray beams characterized by rectangular collimation are used (Figure 8). Regardless of whether a beam alignment device is implemented, collimator cuts will occur if the beam cross-section fails to expose the entire receptor. To decrease the likelihood of cone cuts, the radiographer must carefully align properly positioned detectors and holders to assure that the X-ray beam’s cross-section includes the entire receptor.
Why do dentists use bitewing radiographs?
According to the American Dental Association, bitewing radiographs should be used to help detect interproximal caries in the context of patient risk factors, age, and information gleaned from previous radiographs. 2. FIGURE 1.
Why is my bitewing image not horizontal?
One of the most common errors when exposing bitewing images is failing to prevent horizontal overlapping. Horizontal overlap is a result of the X-ray beam not passing through the open interproximal area at right angles to a properly positioned detector.
Which image should show the distal surfaces of the maxillary and mandibular canines?
The maxillary and mandibular arches should be equally imaged. The premolar image should display the distal surfaces of the maxillary and mandibular canines. The molar image should show the distal of the second premolar and completely include the terminal molars on each side of the patient’s mouth.
What is digital based imaging?
Digital-based systems typically include software that enhances the image quality of problematic exposures, thus avoiding the need to re-expose the patient to ionizing radiation. The choice of digital detector, or receptor and geometrical alignment device can also introduce errors.
What is the best technique for taking a radiograph?

How to minimize gagging?
In addition to being aware of accommodations for missing teeth, bony growths, and narrow or shallow palates, it is also essential to work in a sequence. To minimize the potential for patient gagging, begin by taking the most anterior image. If you are taking a full-mouth series, start with anterior periapical images. For bitewings, begin with the premolar bitewing over the molar bitewing. This will help the patient be more compliant as the procedure continues. 2
What is a handheld xray unit?
Handheld units should be held at the mid-torso height to benefit from the safety effects of the backscatter shield. If clinicians hold the handheld device outside the “safe zone,” they are at risk for radiation exposure.6 Aiming devices are available for handheld devices to prevent operator error. Dentsply Sirona’s XCP-ORA short indicator arms do not interfere with the backscatter shield and allow proper alignment to the patient’s face (figure 5). The universal color-coded pins are helpful and may be used with sensors, PSPs, and film biteblock receptors.
How does digital radiography work?
Digital radiography provides the convenience of electronic images while reducing radiation exposure to patients. Depending on the digital sensor being used, there is a 50% to 90% decrease in radiation exposure. 2 Phosphor storage plates (PSPs) and sensors have become somewhat of a norm. With that said, care instructions and placement are slightly different. When it comes to sensor care, careful handling and proper cord management are two essential parts of maintaining sensor longevity. Phosphor storage plates should be handled with care to avoid scratching or damage to the plates.
