The CAT scan is a relatively recent technique in dentistry, used to get an image of what’s happening deep within your jaws. You may be wondering what a CAT scan tells us that a conventional x-ray picture does not, and whether it is worth the extra expense to get one. And how does a CAT scan compare with a conventional x-ray in terms of radiation exposure?
CAT stands for “computer assisted tomography.” Often it’s just called a CT scan, for “computerized tomography.” The word “tomography” comes from roots meaning “slice” and “write.” Tomographic techniques take repeated two dimensional pictures, similar to repeatedly slicing through an object, and then assembles them with a computer to produce a three dimensional (3-D) image.
The latest type of CT scan used in dentistry is called CBCT, or Cone Beam Computed Tomography. The Cone Beam refers to a spiral beam of x-rays, which is used to create a series of two dimensional images from which a computer creates a 3-D image. Such an image is of great value in assessing problems and planning treatment.
Here are just a few examples of how a CBCT scan can be used. Orthodontists can see skeletal structures and developing teeth that are still inside the jawbone while planning strategies for directing the teeth in order to arrive at a better bite. Oral surgeons can find impacted or missing teeth, see their locations, and view their proximity to nerves and sinuses, assisting them in planning surgeries. These scans are particularly useful for root canal specialists because they show root canals that are less than a millimeter wide and even reveal accessory canals that may not be visible on conventional x-rays. In cases of sleep disorders such as sleep apnea, a CBCT during sleep can be used to view a person’s airway and how it may be blocked by the tongue and other soft tissues in a person’s throat during sleep.
Compared to background radiation, the amount of radiation delivered in dental x-rays is minimal. A CBCT delivers a dose of radiation that is less than a typical full mouth x-ray series but more than a typical two dimensional panoramic radiograph. Generally CBCT scanners deliver lower doses than medical CT scanners.
With one low-dose CBCT scan, we can get an accurate idea of the internal structure of your bones and teeth and how they are situated in relation to each other. Prior to the availability of such images, many of these relationships had to be discovered in the course of a surgery or other treatment. Thus such a scan can aid greatly in the quality of treatment you will receive.
What does spring mean to you? The season officially starts on March 20th, but depending where you live you might start seeing the signs earlier or later. We often think of spring as a time of new beginnings—when the first green buds appear and the earth wakes up from its winter sleep. Spring is also a great time to break out of those old winter routines and make positive changes in your life; for example, learning to manage stress, improving sleep habits and getting more exercise. To those worthy aims, we'd like to add one more suggestion: This spring, make it a goal to improve your oral hygiene!
Maintaining good oral hygiene often results in fewer cavities, reduced gum disease and better checkups at the dental office. But for some people it can mean a lot more. A growing body of research points to a connection between oral health and overall health—especially when it comes to systemic (whole-body) diseases such as diabetes, cardiovascular disease, rheumatoid arthritis and others. In many instances, improving oral health can lead to better management of these diseases.
So how do you start improving your oral hygiene? Glad you asked! Here are a few tips to get you started:
- Brush twice a day with fluoride toothpaste, AND floss once a day—every day! Use a soft-bristled toothbrush for gentle, effective cleaning.
- Limit between-meal snacks to give your mouth a chance to neutralize the acids that can cause tooth decay.
- Stay away from sweetened and acidic drinks like soda (even diet), so-called "sports" and "energy" drinks, and other foods and beverages with a high sugar content.
- Drink plenty of water to increase production of healthful saliva and keep your whole body properly hydrated.
- Visit the dental office regularly for checkups and professional cleanings. This is essential for good oral hygiene. A professional cleaning can remove hardened plaque deposits that can't be cleaned effectively at home. A thorough dental exam can find and resolve small problems before they become big headaches (or toothaches)—and even help prevent them from happening!
Practicing good oral hygiene is the best way to keep your smile healthy for your whole life. And having a bright, healthy smile is a great way to greet the new season!
