ItsanArtDeterminingToothColorinCompositeResinRestorations

It takes a lot of skill, experience, talent and artistry to create tooth restorations that look so natural that no one can tell them apart from the originals. To do so requires understanding of the normal anatomy of a tooth as well as of the interactions of light and color.

How the anatomy of a tooth determines color

The color that we perceive when looking at a tooth results from the combined appearance of the tooth’s center core (dentin layer) and its covering enamel. Going from the outside in, the enamel is made of tightly packed crystals of calcium, which cause it to be one of the hardest substances naturally produced by animals. The crystals are also responsible for a tooth’s brilliance and translucence. The dentin is more like bone, a porous living tissue composed of microscopic tubes, interspersed with more calcium crystals. In the very center of the tooth is a central chamber containing the pulp and nerves.

Each of these layers has its own physical and optical properties. Since the enamel is translucent and the dentin is more opaque, most of the tooth’s color comes from the dentin and is transmitted through the enamel layer. Factors that affect this transmission include the thickness and age of the enamel as well as external tooth whitening.

If the enamel is more translucent, more of the color of the dentin shows through. If it is more opaque, the enamel absorbs and reflects light so that less color is visible and the enamel looks brighter.

The language of color composition and reflected light

Color means the whole spectrum in the rainbow. The spectrum is made up of the three primary colors — red, blue, and green. When all are combined, they create white light.

Hue refers to the brightest forms of the colors. The color we perceive depends on the dominant wavelength of light that is reflected by an object.

Value refers to a color’s lightness or darkness. A brighter color has a higher value.

Chroma is the amount of identifiable hue in a color. An achromatic color (without hue) appears gray.

Saturation is a measure of a color’s intensity.

This terminology of color is used not only by dentists and dental technicians, but also by a wide range of artists. It implies expertise and understanding of how colors work, how they vary and change and affect one another.

3ReasonsforBloodPressureChecksDuringDentalVisits

You may have been surprised by a new addition to your regular dental appointment routine—we took your blood pressure at the start. While you might expect this at a medical clinic, it seems unusual at the dentist’s office.

But not anymore: blood pressure checks at dental offices are quickly becoming routine, including during regular cleanings and checkups. Here are 3 reasons why checking your blood pressure is now part of your dental visit experience.

Your blood pressure could be an issue during dental work. While we do everything possible to make you comfortable, undergoing dental work can create stressful feelings. Blood pressure normally increases when stress occurs, including before dental procedures. If you already have issues with hypertension (high blood pressure), any circumstance that might increase it could lead to health problems or even an emergency like a stroke. If your blood pressure is high, we may forgo any planned procedures and refer you to a physician for further examination.

Local anesthesia can affect blood pressure. Local anesthesia is an important part of dental work—without it we couldn’t provide maximum comfort during procedures. But many anesthetics include epinephrine, which helps prolong the numbing effect. Epinephrine also constricts blood vessels, which in turn can elevate blood pressure. We may need to adjust the anesthesia drugs and dosages we use in your case if you have high blood pressure.

It could save your health—and your life. The symptoms for hypertension can be subtle and often go unnoticed. A blood pressure screening check is often the first indication of a problem. That’s why blood pressure screenings in a variety of healthcare settings are so important. A routine blood pressure check at your dentist (who hopefully sees you at least every six months) is one more opportunity to find out. Discovering you may have high blood pressure is the first step to controlling it and hopefully avoiding more serious conditions like diabetes or cardiovascular disease.

If you would like more information on monitoring vital signs during dental visits, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Monitoring Blood Pressure.”

BitewingX-RaysSafelyRevealallAboutBackTeethtoPreventToothDecay

Modern dental care wouldn’t be the same without x-rays. Since dentists began capturing x-ray images a century ago to detect beginning tooth decay, billions of teeth have been preserved.

“Catching it early” is the key to staying ahead of this aggressive bacterial infection. Once it breaks through the protective defenses of tooth enamel, it can advance toward the center of the tooth, the pulp, damaging dentin as it goes. While we can effectively stop it at this point with a root canal treatment, it’s better for the tooth’s long-term health to detect and treat any decay early on with a less-invasive filling or other treatment method.

X-ray imaging helps make that possible, revealing decay much easier than we can see with the unaided eye. And while we can often detect decay in front teeth by visual examination or by using very bright lighting, that’s not as easy with the less accessible back teeth. For those teeth we use a special x-ray technique known as the bitewing.

The name comes from the small frame used to hold the film. It’s held in place in the mouth by the patient biting down on small tabs or “wings” extending from the frame. The x-ray beam travels through the outer cheek and teeth to the film being held in the frame on the back side of the teeth. When exposed, we’ll be able to view the interior of these back teeth: a set of four bitewings gives us a full view of all the upper and lower molars and pre-molars on each side of the jaws.

Like other forms of radiation energy, too much or too frequent exposures to x-rays can lead to serious health problems. But bitewing x-rays carry little risk to health. That’s because they fit well with the ALARA principle, meaning “As Low As Reasonably Achievable,” which helps guide our use of x-rays. Patients receive a fraction of the radiation exposure from routine bitewing x-rays than they receive annually from the natural environment.

Without bitewing x-rays and other diagnostic methods, the chances are high that tooth decay or other dental problems can go undetected in their early stages. Using this important tool can help us head off major damage before it occurs.

If you would like more information on the role of x-rays in dental care, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Bitewing X-Rays: A Routine Part of Your Dental Exam.”
