Detecting and preventing dental caries: Dental assisting
Dental caries, also known as tooth decay, is a significant worldwide health concern for both children and adults. Prevention and early detection of dental caries help to preserve tooth structure, support long-term function, and reduce the need for costly and uncomfortable restorative treatments.
As a dental assistant, you'll play a key role in helping prevent tooth decay, identifying risk factors for dental caries, and assisting the team in spotting early signs of decay before it progresses.
Now, the primary method of detecting dental caries is through visual and tactile inspection. A round-tip, blunt explorer or probe, is used to investigate areas on the teeth that look suspicious due to changes in color or texture.
Carries can appear as discolored spots, and have a sticky texture when the probe is pressed against it, indicating the enamel has weakened.
Radiographs, such as X-rays, are useful in identifying carries that are difficult to diagnose through inspection, such as interproximal carries, which are carries that form between two adjacent teeth, as well as secondary or recurrent carries that form on the edges of an existing restoration.
When carries are present, they appear as dark spots or shadows on the image. It's important to keep in mind that although imaging is an essential tool for detecting dental carries, early carries might not be visible on X-ray.
There are also some advanced carries detection technologies that can increase the accuracy of dental carry's diagnosis. These tools don't replace a thorough clinical exam, but they provide additional information that supports better diagnosis and treatment, while the decay is still small.
The trans illumination fluorescence device is one of those advanced technologies. This device uses a laser to direct a light onto the surface of the tooth, and then collects the resulting fluorescence emitted from the tooth.
Another advanced imaging tool is optical coherence tomography, or OCT. A small handheld device uses light waves to create a detailed cross-sectional image of a tooth.
These images are particularly helpful in detecting decay hidden under restorations and sealants. Now, let's focus on how to assess a patient's risk for dental carries.
First, the CARE Management by Risk Assessment, or CAMBRRA for short, is an evidence-based approach to preventing and treating dental carries early.
The goal of CAMBRA is to assess each patient's unique risk and protective factors for carries, and develop an individualized treatment plan based on whether their risk is low, moderate, high, or extremely high.
Another assessment method is the American Dental Association CARE Classification System, or ADACCS, which identifies the location, site, extent, and activity level of the patient's carious lesions over time to guide individualized treatment.
Lastly, Cy's risk tests, or CRTs are another evaluation tool used to measure the number of mutant streptococci and Lactobacilli bacteria in an individual's saliva, with high numbers indicating a higher risk for dental carries.
Each of these tools aims to promote an individualized prevention and treatment plan tailored to each patient's risk factors and severity of carious disease.
Now, let's take a look at how you can help your patients prevent dental caries. Begin by teaching your patients to limit sugary foods and drinks, starchy foods, and candy.
And recommend chewing some sugar-free gum containing Xylitol or baking soda after snacks, as this will increase saliva flow and help neutralize acids.
Review the importance of consistent oral hygiene, including brushing and flossing, to remove plaque from the surfaces of their teeth.
And explain how fluoride products help to make teeth more resistant to acid. So, using a fluoride-based toothpaste is important, especially if their local drinking water isn't fluoridated.
Also, let them know that the application of dental sealants on the biting surfaces of the back teeth is an excellent way to prevent carries in children and young adults.
Finally, emphasize the importance of regular visits to their dental office for professional cleaning and examination. As a dental assistant, you'll help the dental team identify patient risk factors for dental caries, and assist with diagnostics, planning, and coordination of care.
You'll also provide education to promote oral health and prevent dental caries. All right, here's a quick recap.
Dental caries is a common chronic disease, but prevention and early detection helps preserve tooth structure, support long-term function, and reduce the need for costly and uncomfortable restorative treatments.
As a dental assistant, you'll play a key role in helping prevent dental decay, identifying risk factors for dental caries, and assisting the team to spot early signs of decay before damage to teeth progresses.
