Digital X-ray


digital xrays at Star City Dental in Lincoln, NE Just as with many other medical exams, there is only so much that a dentist can detect with a visual exam. Here at Star City Dental, we often have to make use of more advanced diagnostic tools to discover problems that lurk beneath the surface. Digital radiography provides a means by which our team can make an accurate diagnosis and prescribe the correct treatment.

Digital radiography is how current dental x-rays are developed. A sensor is placed in your mouth to help capture images. It needed to a computer where the images are transmitted to, and the image is projected on to the screen for our dentist to see.

Merits of Digital Radiography


When compared to traditional dental x-rays, digital radiography offers much less radiation exposure. Digital x-rays reduce exposure by as much as 90% vis-à-vis film x-rays. This should reduce any anxiety if they may need to be taken severally with more complicated dental problems.

The speed at which the images are brought into view also means quicker diagnosis for the patient, and shorter appointments. Rather than having to go and come back later, the results are instantly developed, allowing any problems to be attended to immediately by our team.

Not only are the images that appear much clearer than with traditional film x-rays, but they can also be more easily manipulated. Our dentist can magnify, brighten, or contrast the image as desired to get a better view. This makes for diagnosis that is more accurate. Even the smallest of cavities can be better detected and allow for early and minimally invasive treatments.

Film x-rays used to be problematic, not just because they often came out fuzzy, but also the method by which they were developed. The chemicals used were often hazardous, and special rooms had to be designated for this use. Now all the equipment can be stored in the exam room without the risk of hazardous chemicals.

Storage of client information is also made easier as these images can easily be saved on a computer and even transferred to another office in case of a referral. This helps reduce the need for cabinet space in our offices and you no longer have to carry around an envelope with bulky x-rays.

How It Works


The digital images go through an analog to digital conversion (ADC) process. ADC is a two-step process that begins with sampling. During sampling, a small series of voltage values are taken as a single value. When sampled, each sampled signal is assigned a value. When the computer receives the pixel data, it must organize the information into their correct location and display shades of gray that correspond to the value assigned. This part of the process is referred to as quantization.

An x-ray tube head is used to bombard the sensor plate with photons that convert the analog image into digital. This data is what is transferred to the computer as pixels. Pixels are image matrixes of rows and columns that indicate the varying gray levels of each location of the image. Using digital imaging software allows these pixels to be translated into a coherent image with varied gray shades that bring out a clear image of the teeth being examined.
