When you have a dental emergency — whether it's caused by a sudden accident or chronic disease — your teeth and/or the tissues of the mouth that surround them need to receive proper care right away. It's also important to be aware, before you're actually in the situation, of what you can do to ensure the best outcome. Read more about Emergency Dental Care.
This is the branch of dentistry that focuses on the inside of the tooth — specifically the root canals and sensitive, inner pulp (nerve) tissue. When this tissue becomes inflamed or infected, a root canal procedure may become necessary. But contrary to the popular myth, a root canal doesn't cause pain, it relives it. Read more about Endodontics.
If you are missing one or more teeth, dental implants offer the comfort and security of a permanent replacement that looks and functions just like your natural teeth. Dental implants also help preserve the tooth-supporting bone in your jaw that naturally deteriorates when even one tooth is lost. Read more about Implant Dentistry.
Oral health is an essential component of general health and well-being. Good oral health means a mouth that's free of disease; a bite that functions well enough for you to eat without pain and get ample nutrition; and a smile that lets you express your happiest emotions with confidence. Read more about Oral Health.
A major goal of modern dentistry is to help you keep your teeth and gums healthy for a lifetime. By following a conscientious program of oral hygiene at home, and coming to the dental office for routine cleanings and exams, you have the best chance of making this goal a reality. Read more about Oral Hygiene.
The word “surgery” often brings to mind a stay in the hospital, general anesthesia, and perhaps a lengthy recovery period. However, the experience of having oral surgery is usually very different from that. Some common oral surgery procedures include: tooth extractions, dental implant placement, and biopsies of suspicious oral lesions. Read more about Oral Surgery.
Adults and kids alike can benefit from the boost in self-confidence that comes from having a great-looking smile with beautifully aligned teeth. Orthodontic treatment can even improve chewing, speaking and oral hygiene in certain cases. And with today's virtually invisible orthodontic appliances, it's possible to keep your treatment a private matter… until your new smile is unveiled, of course! Read more about Orthodontics.
It's never too early to get your child started on the path toward a lifetime of good oral health, and there are many services to do exactly that. Monitoring your child's dental growth and development, and preventing and intercepting dental diseases along the way, is the primary focus of pediatric dentistry. Read more about Pediatric Dentistry.
If you want to keep your teeth for life — a completely reasonable goal in this day and age — you need to make sure the tissues that surround them are also healthy. Should gum problems arise, you may need periodontal therapy to restore diseased tissues to health. Read more about Periodontal Therapy.
In the field of dentistry, new technology is constantly changing the way diseases are diagnosed, routine procedures are performed, and illnesses are prevented. Although they may seem unfamiliar at first, new and improved dental technologies offer plenty of real benefits for patients. Read more about Technology.
In the early 20th Century, not long after X-rays were discovered, medical professionals recognized their value as diagnostic tools: They could clearly reveal structures hidden inside the body without the need for risky surgery. At the dawn of the 21st century, a revolutionary new technology has entered the diagnostic arena. Today, Cone Beam Computed Tomography (CBCT) promises to change the way many dental problems are diagnosed and treated.
Cone Beam CT has some similarities with conventional X-rays, and also with the standard CT scans you would get in a hospital setting. But it's a quantum leap forward in technology and diagnostic precision. For the dentist, it offers the ability to visualize intricate structures inside the mouth, such as root canals, nerves and sinuses (air-filled spaces) in the jaw — in three dimensions — without surgery. For the patient, it can reduce the need for invasive procedures, shorten treatment time and offer the chance for a better outcome.
The detailed diagnostic images that CBCT provides have made it an essential tool in many dental specialties. But, as with any diagnostic tool that uses radiation, the medical benefits offered must be weighed against the (small) potential risks of the procedure.
How Cone Beam CT Works
X-rays, like visible light, are a form of energy on the electromagnetic spectrum. Just as light makes an image on photographic film (or a digital camera sensor), X-rays can also form an image. The difference is that energetic X-rays can penetrate bone and soft tissue, and reveal its hidden structure by their varying degrees of absorption; in other words, they form a grayscale picture of what's underneath the surface. But conventional X-rays are limited: Like a still-life picture, they show only one perspective on the scene.
Now imagine a “flip book” — the kind of small book made up of a series of pictures, each slightly different. When you rapidly page through it, you may see (for example) an animated cartoon or a still subject from different perspectives. If you could put together a flip book made from a series of X-ray “slices” of the same subject, taken at slightly different angles, you would be able to create an “animation” of the X-rays. And from there, it's only one more step to making a 3-D model.
That's exactly what CBCT scanners do. Using a rotating imaging device that moves around the patient's head, the scanner records between 150 and 600 different X-ray views in under a minute. Then, a powerful computer processes the information and creates a virtual model of the area under study. When it's done, the model appears as a three-dimensional image on a computer screen: It can be rotated from side to side or up and down, examined in greater or less detail, and manipulated in any number of ways — all without the patient feeling any discomfort... or even being present.
Where Cone Beam CT Is Used
The ability to see fine anatomical structures in 3-D has proven invaluable in treating conditions in many areas of dentistry.
- Orthodontics: Having accurate information on the position of teeth and jaws helps determine exactly how and where teeth should be moved.
- Dental implants: Detailed CBCT images are used to determine the optimum location for the titanium implants while avoiding nerves, sinuses and areas of low bone density.
- Orthognathic Jaw Surgery and Temporo-mandibular Joint (TMJ) Disease: Patients benefit when the specialists who treat these conditions can evaluate their anatomy with the three-dimensional perspective that cone beam CT provides.
- Oral Surgery: Treatment for tumors or impacted teeth is aided by the level of fine detail shown in these scans.
- Endodontics: Dentists performing intricate procedures (like complex root canals, for example) can benefit from a clearer visualization of the tooth's anatomy.
- Sleep Apnea: Imaging the tissues and structures of the nose, mouth and throat can aid in diagnosis and treatment of this dangerous condition.
Could Cone Beam CT Benefit You?
Each patient's situation is different, and must be carefully considered by a clinical professional before any test or procedure is performed. While CBCT delivers a smaller dose of radiation (X-rays) than many other diagnostic tests, it still carries a small risk — particularly for younger patients, or those with other health problems. As is the case for any medical procedure, all risks, benefits and alternatives are taken into account before the procedure is recommended.
Getting The Full Picture With Cone Beam Dental Scans Dental imaging took a major leap forward at the beginning of the new millennium with a three-dimensional technology known as cone beam computed tomography (CBCT). The name comes from the cone-shaped beam of x-rays the CBCT machine projects as it rotates around a person's head, taking multiple images that are compiled into a 3-D picture by a computer.
