Have you ever wondered how x-ray machines work? This technology is used every day by hospitals and dentists to see inside the body where the naked eye cannot. It helps reveal the underlying causes of a range of health conditions and gives doctors an accurate depiction of what is going on with their patients. In particular, dentists use x-ray machines to assess a person's jaw structure and for detecting possible tooth decay; before these devices were invented, they had to rely on judgment for administering a treatment plan. Tooth decay can be caused by many factors, including poor genetics, improper oral hygiene and excessive intake of foods high in sugar and starch. Given that it is one of the most common dental health afflictions, x-rays are an essential tool for every dentist.
What are X-rays?
X-rays are a type of electromagnetic radiation that allows dentists to take internal pictures. The energy emitted by the machine passes directly through the body, albeit at safe levels, which in effect illuminates everything it comes into contact with. Since x-rays react differently to denser materials, the image that results will contain the colors black (air), white (metal fillings) and gray (teeth and gums). The visible contrast between each of these is what gives dentists the information they need. If a problem like a tooth decay is present, they will immediately be able to pinpoint its location and act accordingly.
What Types of Dental X-Rays are Used?
Dentists use many types of x-rays, depending on the specific needs of the patient and the purpose and intent of the test. For instance, bitewing x-rays are taken to assess the alignment between the upper and lower teeth, as well as bone loss which could be caused by gum disease such as gingivitis. On the other hand, a periapical x-ray is geared towards taking images of individual teeth; it provides a comprehensive view of a tooth in its entirety, from the crown to the underlying roots. This test is often implemented when oral diseases are suspected in the gum and jawline. Other popular x-rays include Occlusal (an image of the lower region of the mouth), Panoramic (an expansive view of the mouth and nasal passage). Advancements in technology have also led to the development of digital x-rays, giving the dentist the ability to save patient images on a computer. Since these x-rays can be used to compare oral changes, they are bound to become more popular in the coming years.
A dental x-ray is something most people will have to get in their lifetime. This technology is safe and extremely effective at detecting problems and was previously unnoticed.
