The effects of radiation can be hazardous to any part of the human body. In this guide I will explain the advantages, and disadvantages of x-ray radiation. I will also discuss the technological advances that we have today then of what we had the past on the human body during radiation exposure. I will explain preventions of exposure and safety precautions that we as dental assistants as well as patients can follow to stay safe.
The X-Ray was invented in 1895 by Wilhelm Conrad Roentgen. It all started with a vacuum tube called a Crookes tube, with this Roentgen noticed that by pressing a button that activated an electric current through it a shadow was projected onto a screen that showed the photograph of his wife’s hand with a ring on it. When he took the first x-ray of her hand it took him 25 minutes to finish the photograph. With this invention Roentgen won a Nobel Peace Prize for physics in 1901.
From 1895 to 2014 there have been many updates to the x-ray. One of those being a cryptoscope, this is a lead glass fluorescent screen. They also introduced the lead glass goggles. These were a centimeter thick pair of glasses that offered protection against cataracts and glaucoma. Since the past the medical field has come a long way since the discovery of the x-ray. They are calling it the “Golden Age of Radiology,” said Kathern A Brodsky. From the past to the present there has been a decrease in exposure effects and an increase in safety technology with radiation exposure.
When the introduction of computers and transistors came along there has been a significant reduction in x-ray radiation. We now have a two-dimensional and three-dimensional imaging system which makes it able to move images that are taken from the x-ray away from static interpretation and make them more of a real-life picture. They are more clear and able to see then what it was in the past. They also have the PID which is also known as the “position indicating device.” This allows the image to be in one general area of the patient other then all over the head and body. The PID can be moved up to the patients mouth where the x-ray needs to be done.
There are many advantages of x-rays in dental radiation. We can use the x-rays to detect and confirm any diseases or lesions that may be in the mouth. They detect any trauma that may have happened to the teeth and or gums. We use x-rays to look and study the growth and development of teeth and gums in children and adults. With the advancement of the x-ray we can also detect any tumors, teeth that are missing or are coming in at an abnormal direction as well as educating the patients about their mouth and teeth.
With the equipment that we have today and with the digital radiography images we are decreasing exposure by 80% in patients. Believe it or not, your appointment can be shorter to the dentist with the advances in the technology. With the use of digital radiology, the x-ray is developed in minutes,...
