For this reason, efforts are made to reduce radiation exposure and utilize only the necessary amount to assess the area of interest. Overall, the benefits of obtaining X-ray images for diagnosis far outweigh the risks, as they play a vital role in identifying oral health issues that may not be visible during routine exams (University of Michigan School of Dentistry).
To illustrate the radiation levels of dental X-rays, the following table compares the exposure to common sources of radiation:
| Source of Radiation | Equivalent Exposure (in microsieverts) |
|---|---|
| Single Dental X-Ray | 0.005 |
| Natural Background Radiation (per day) | 0.010 |
| Flight from New York to Los Angeles | 3.0 |
| Chest X-Ray | 100 |
Digital vs. Traditional X-Rays
When comparing digital to traditional dental X-rays, the differences in radiation exposure are significant. Digital dental X-rays utilize approximately 80% to 90% less radiation than traditional X-rays, making them a safer option for most patients.
Digital X-rays offer added advantages, including faster imaging results and reduced need for re-takes due to improved image quality. Additionally, the images can be easily stored and shared electronically, enhancing the diagnostic process.
While both types of X-rays are essential for revealing structures like jaw bones and teeth roots that are not visible during a routine check-up, patients should discuss with their healthcare provider which type would be most suitable for their specific needs.
