The Importance of Dental Intraoral Cameras

Intraoral cameras have incredible technological features. With LED lighting, a head that rotates from 0 to 90 degrees, and powerful magnifying capabilities (some cameras can zoom in up to 100x), your dentist can examine your mouth in extreme detail. This means he or she can make diagnoses more accurately. The office can attach these photos to your health record to make tracking any changes simple.

Early diagnosis allows for earlier and less invasive interventions such as remineralization therapy or a preventive resin restoration. Pairing advanced diagnostics with the ability for patients to visualize their oral health conditions creates an urgency for patients to move forward with these minimally invasive treatments. Early detection creates a powerful call to action for both the dentist and patient alike.

The dental explorer is said to have an accuracy of about 25%, and traditional radiographs have been reported to be about 68% accurate, but the tooth structure has to undergo enough damage for the lesion to become visible and by that time the patient is definitely getting a filling. These traditional lesion detection modalities are simply not capable of spotting small, early pathologies. But new technologies are now available to help clinicians locate and quantify potential problems in the gingival tissues as well as the teeth.

Each feature that benefits the dentist also benefits the patient—maybe even more. Your dentist understands symptoms and conditions thoroughly, but it’s often difficult to explain precisely what is happening in a patient’s mouth using just a mouth mirror, which is small and hard to see, or an x-ray image, which takes time to print and doesn’t display images clearly.

When your dentist uses an intraoral camera during your examination, however, you’re seeing exactly what he or she sees right then. Dentists can display clear, colorful images, allowing them to point out any issues and discuss them with you immediately. You’ll certainly learn a lot about your mouth! And the more you see and understand, the more confident you can be when making treatment decisions.

The intraoral camera makes record keeping a breeze. Because the camera can take pictures of decay or the beginnings of oral health conditions, images can be printed and placed into patient files. Previously, dentists merely attempted to write an explanation of problems found during exams. Now, dentists can accurately track the progress of treatments or problems for years following a visit. Furthermore, patients can receive printed pictures of the conditions the dentist finds, which may be beneficial for filing insurance claims.

How to Protect Your Eyesight When Using Dental Curing Lights

Curing lights are used primarily in the dental industry, where they are used in fillings, sealants, and adhesives for various dental procedures. Other versions of the curing light can be seen in use in manufacturing, where rapid and even curing can be an important part of the manufacturing process. A number of companies produce curing lights which have been custom designed for particular applications, ranging from electronics to dentistry.

In the dental field, a dental curing light can use ultraviolet or visible light, depending on what it is designed for. Both dentist and patient need to wear eye protection to limit damage to the retina for even the 20 seconds to a minute that the light is in use during rapid curing, and the light needs to be well maintained so that it will work properly and effectively. It’s also important to use the right curing light for the right resin product; many lights are designed to handle a range of resins safety.

When dentists or any member of a dental team uses dental curing lights, protective eyewear or a shield to cover the light-curing unit (LCU) is a must. Ophthalmic research shows that short wavelength light like that commonly used in dental curing lights may contribute to premature aging of the eye’s retina and to senile macular degeneration.

Light with wavelengths of less than 500nm, also known as near ultraviolet or blue light, has been shown to cumulatively harm the eye’s retina and decrease the ability of the macular region of the retina to provide sharp vision. This light may also be connected to the formation of cataracts.

Resin-based restorations and dental sealants are cured by light in the 370nm to 470nm range. Reliable research shows that this area below the 500nm range can be harmful to vision. Therefore, the use of appropriate eye protection or a shield when operating a dental curing light is essential. Any protection should filter out the majority of light that is less than 500nm.

Studies have shown that looking away while curing frequently allows the curing light tip to drift slightly, causing inadequate amounts of energy to be delivered to the restoration. Curing lights in use today provide very intense blue light and very short cure times, so even a slight drift reduces the amount of energy delivered to the restoration by a significant percentage.
