Why are Dental X-Rays Important?

September 27, 2011 in Dentistry by McCarl Dental Group

Sometimes our patients ask “why is it important that I have x-rays taken when I come for my check-up?” The short answer is dental x-rays also called  radiographs can show us things that we cannot clinically see with our own eyes.

The dentists and dental hygienists at the Millersville and Greenbelt offices of McCarl Dental Group follow guidelines determined by the American Dental Association (ADA). The ADA standard of care is to perform routine intraoral radiographs once a year for most patients. These are the films that we normally refer to as “bitewing” x-rays. The other type of radiographs, Panoramic or Full Mouth Series of films, are normally taken once every 5 years. Occasionally there will be the need to take an x-ray of just one tooth for treatment or monitoring. To help provide incentive for people to get very important preventive care, we offer special discounts for an introductory visit with teeth cleaning, evaluation by a dental hygienist, dental x-rays as necessary and an exam by a dentist. The comprehensive dental exam also includes an oral cancer screening.

Each type of dental radiograph works in a different way. A panorex/panoramic film shows us a broader view of the entire oral cavity, bone structures and anatomy surrounding the teeth. This allows us to screen for any problems such as cysts, bone degeneration or missing teeth.

Bitewing x-rays are more detailed and allow us to closely look into the contact area between your back teeth. This is an important area to watch for early signs of decay and periodontal disease. A periapical x-ray will show us more of an individual tooth than a bitewing, and allow us to see around the tip, or apex of the tooth. These smaller films, the bitewing and PA, also allow us to detect abscesses and monitor the quality of existing dental work.

Without x-rays, we might not be able to see dental problems like failing restorations, recurrent decay, or a tooth abscess in the earliest stages. By the time many of these symptoms become evident visually, they are advanced and causing notable discomfort. That’s why coming in for routine dental hygiene cleaning and dental examinations can prevent more advanced treatments later. Our goal is to prevent dental problems and maintain a healthy smile. Dental x-rays help us achieve that goal.

Dental x-rays are extremely safe. They use minimal levels of radiation, and newer digital x-ray equipment uses even less. We are able to view and discuss digital x-rays with our patients on a large television screen in the dental operatories. This allows our patients to see what we are seeing and understand the treatment process better. Patients who have an increased risk of decay, or who suffer from periodontal disease may need more frequent radiographs. This is to help us monitor any suspected areas and intervene with therapy before problems progress to a more severe stage.

If you’re behind on your dental care or need to schedule your routine dental cleaning and exam, call us at our Millersville, MD dental office (410) 987-8800 or Greenbelt dental office (301) 474-4144 to schedule a check-up. www.mccarldental.com

Do Dentists Really Recommend Chewing Gum?

September 19, 2011 in Dentistry by McCarl Dental Group

We all know that gum can be bad for you. Sugar containing gum actually increases our risk for tooth decay. Cavities that develop from chronic gum chewing often are not very noticeable in plain view. A small hole will be evident on the tooth enamel, but when an x-ray is taken, half of the tooth is “bombed out” on the inside. This type of decay is unique to gum chewing. Even when excellent oral hygiene habits are in place, frequent gum chewing continues to cause decay of the teeth. (i)

Sugary chewing gum can increase your risk of tooth decay.

Sugary chewing gum can increase your risk of tooth decay.

Now there are now chewing gums available that have the sweetener Xylitol. Xylitol containing gums have actually been shown to reduce tooth decay and encourage enamel remineralization.(ii) Further studies show that chewing a gum with Xylitol encourages healthier gums, reduces bleeding, and decreases harmful bacteria.(iii) For patients who are actively fighting gum disease and recurrent tooth decay, chewing these gums may be beneficial to their oral health.

According to the American Dental Association, chewing gum may also be beneficial for patients with dry mouth. Medications and certain medical conditions are a common cause of dry mouth. Radiation therapy may also be the culprit, as it can destroy the salivary glands within the mouth. When there is no saliva to cleanse the teeth on a normal basis, decay becomes rampant. Xylitol containing gum promotes salivary production and can help decrease the decay rate. Dry mouth can also be very uncomfortable, and salivary supplements that don’t damage your teeth are extremely important. While the old school of thought might have been to suck on a peppermint, we know this is not the healthiest option for our teeth. Within just 5 to 10 minutes of chewing gum, saliva production will peak.(iv) Chewing a Xylitol gum may be a good option to decrease the dental consequences and discomfort of dry mouth.

Research indicates that chewing  gum containing Xylitol can be beneficial to dental health. Check the labels of different brands of chewing gum. You’ll be able to see on the front side of the package, usually in the corner, whether or not Xylitol is an ingredient. Brands like Orbit and Trident use this sweetener in most all of their products. If you or your children enjoy chewing gum, the American Dental Association recommends that you choose gum that contains Xylitol.

It is important to have routine dental hygiene cleaning and preventative oral health care.

iTero Dental Digital Oral Scanner

September 15, 2011 in Dentistry by McCarl Dental Group

Have you seen our  iTero Digital Scanner? It looks like R2D2 and talks to us in a robot voice! It makes crowns, bridges and veneers from hundreds of images of your teeth instead of from rubber impressions.

At McCarl Dental group in Greenbelt and Millersville, MD we are excited to be using the advanced iTero technology that almost completely eradicates the need for conventional dental impressions. Instead, the iTero device allows a virtual 3D impression to be taken of the patient’s teeth in about the same amount of time that it used to take impression material to set and harden.

iTero technology works by using an intra-oral scanner that takes approximately 300 slices of information with 100,000 points in each picture. A voice-guided computer program navigates the clinician on proper placement of the scanning mechanism, so that a thorough image is recorded. These different layers of information are laced together to create a 3D image of the teeth.

Because the iTero impression technology is extremely accurate, it improves the seating of restorations like crowns and bridges by requiring little to no adjustment to the fit of the restoration when it is permanently placed into the mouth. With conventional impressions there are numerous steps to be taken, all of which require extreme detail, and all of which can alter the way a dental restoration fits into the mouth. With iTero, these other steps are not required, and the precise digital 3D image ensures proper fit of the final restoration.

Our patients love the iTero because there is no need for taking traditional impressions that may trigger a gag reflex. The iTero also saves time for both our patients and our staff by shortening appointment length and doing away with the need to fabricate models in our own dental lab. Instead, the 3D impression is sent wirelessly to the iTero laboratory that takes the information and creates an accurate polyurethane model of the teeth, which is sent to the dental technician who will create the crown, bridge, veneer, or other dental restoration. The need for re-impressions, sometimes needed with conventional impressions, is not a factor with iTero technology.  This also helps McCarl Dental do its part to go green, by reducing consumables and waste products.

The iTero digital impression allows restorations to be made from all types of materials, whether porcelain or gold, it doesn’t matter. McCarl Dental Group uses the iTero to scan for various restorative and cosmetic dental procedures like crowns, bridges, veneers, onlays and inlays.

If you’ve been putting off dental treatment because of dental impressions or other conventional treatment, call our Millersville or Greenbelt, MD locations at (410) 987-8800 or (301) 474-4144 to schedule an appointment.

Advances in Dental Hygiene

We have seven very talented dental hygienists who work at our dental offices in Greenbelt and Millersville Maryland.

Greenbelt and Millersville Maryland Dental Hygienists

Greenbelt and Millersville Maryland Dental Hygienists at McCarl Dental Group

 

Recent years have shown tremendous strides in the advancement of technology in the area of dental hygiene. The Dental Hygienists at McCarl Dental Group stay current with the latest advancements so they are able to deliver the highest quality dental hygiene care.  Several of our hygienists have worked at McCarl Dental Group for more than 20 years! Our patients always give fabulous reviews of their dental hygiene care. Because prevention and early intervention is key at your professional dental cleanings with the hygienists at McCarl Dental Group, we want to take a moment to share some of the technological steps that preventative dentistry is making.

  • Desensitization

For patients who suffer from tooth sensitivity that does not require restorative dental treatment, desensitizing agents are now more effective than ever.  McCarl Dental Hygienists can apply topical gels that make your teeth “pain free.” Fluoride varnish helps block the pain receptors of the hypersensitive tooth surface. Our dentists can also provide prescription strength fluoride toothpaste for everyday use. This allows patients to eat and drink without associated tooth sensitivity and helps ensure dental comfort between dental appointments.

  • Digital Radiography

In the beginning of dental radiography, x-ray films had to be dip processed in 3 separate tanks with chemicals that allowed the films to be viewed. This development process took 20 minutes. Electric processors shortened this time dramatically, usually developing an x-ray within 5-7 minutes after being placed in the machine. In the 21st century with digital radiography, the images are ready for viewing in an instant. McCarl Dental Group uses digital radiography machines for several types of x-rays. This shortens the time it takes to view x-rays and decreases radiation exposure to our patients. While the exposure levels with traditional films were already safe, digital radiography lowers exposure even more. The detail and resolution of digital radiographs is of extremely high quality, and the files can be sent electronically to other dental professionals or insurance companies.

  • Local and Systemic Delivered Medications

For patients who suffer from periodontal disease, in addition to procedures such as Scaling and Root Planing, local delivery of medication to areas with advanced bone loss can improve healing as well as encourage tissue attachment and bone regeneration. (1) These medications are placed below the gum surface into the infected pocket area, and are delivered through fibers, gels, chips, ointments and microspheres.

Recent studies also show that Statin drugs, commonly used to control blood cholesterol, are suggested to improve tissue attachment on the root surfaces of teeth, and encourage bone growth. (2) Azithromycin, another orally delivered medication, has also been shown to improve the success in Scaling and Root Planing therapy. (3)

At McCarl Dental Group  we strive to provide state of the art, quality preventative, restorative and cosmetic dental care to each of our patients. To find out more about the advanced dental care we offer in Millersville, MD and Greenbelt, MD, please call us at (410) 987-8800 or (301) 474-4144.
