Once certified in taking the thermographs, some things become obvious to the technician, such as extreme hot spots. In a black-and-white thermal image, the darker colors are hotter. Shades of red and white display areas of inflammation. When examining a thermograph, blue is cold. Victoria DaCosta, RDH, started a company to provide training about thermographic imaging. A thermograph may be able to help the doctor make an earlier diagnosis and start treatment earlier. For instance, consider patients who return time and time again to say a tooth hurts or is bothering them, but radiographs find nothing. False positives are rare and save thousands of hours in worry and heartache in tens of thousands of women with benign cysts and other artifacts apparent in the traditional mammography.Īlthough breasts are far afield of dentistry, thermography can help us detect early inflammatory changes in the oral cavity long before it shows up on the film. Thermal changes in breast tissues occur long before the mass is detectable. In cancer lingo, any measurable size is approaching late stage. In traditional mammography, a mass must grow to a detectable size in order to show up on the screen-the difference between an early symptomatic lesion and one that shows up on radiographs. Thermography has been proven to detect changes earlier than mammography. Since the 1950s, scientists have been measuring minute temperature changes in human tissue. Did you know that a medical technology in the 1950s was developed and refined to where it can now detect temperature changes to within a 100th of a degree up to 3 centimeters below the surface with high accuracy? All inflamed tissues, by definition, are exothermic. The answer to this crazy problem diagnosis of oral inflammation may be the yet unexploited feature of inflammation: heat. Fluorescence will show only surface inflammation, such as gingivitis. Bring the heatįluorescence in caries and decay detection is great. The drive to find less invasive diagnostics is on. Blood sampling can be a huge financial boon in the dental practice, but we just mop it up and toss it, much as we do with saliva. I'm not sure why, as the patient bleeds more during a dental procedure than any physician's procedure. The inflammation can come from periodontal disease, early apical lesions, undetected cancers, sprained ankles, or adipose tissue.īut blood tests are not well received in the dental office. They don't really tell where the problem lies. As part of a blood panel for treating periodontal disease, high sensitivity C-reactive protein (hs-CRP) tests can give vital information. Doing a test to measure C-reactive protein can give a clinician a great way to find inflammation somewhere in the body. Unless it is on the surface and obviously red and hot, there are very few ways to measure inflammation.

Inflammation is difficult to quantify and locate. READ | Dental hygiene career options: Dental systemic thermographer The bigger story is the system-wide inflammation due to the cardiovascular superhighway. Periodontal pathogens have been found in the heart, brain, placenta, amniotic fluid, and the lungs of stillborn infants. Researchers have found periodontal pathogens in organs far from their normal habitat. In the recent past there has been a huge wave of science supporting the link between periodontal inflammation and cardiovascular disease. Wait, what does that heart attack have to do with anything? A second procedure was performed at age 45 the patient had a heart attack and the tooth was removed shortly after. 30? Well, the root canal therapy performed was successful for only three years before it started acting up. Two other teeth have occlusal prosthetics. The rest of the teeth in the mouth are fine. Then, at age 34, a root canal was performed. By the time the patient was 25, the tooth needed a crown at age 32, recurrent decay forced a buccal resin. At that time, it was replaced by a two-surface prosthesis that grew into a three-surface prosthesis. The first prosthesis (an occlusal flowable composite) lasted just five years. As one of the first permanent teeth in the mouth, its history was not stellar. The image on the screen is a black-and-white skeletal rendering of a tooth the patient has been dealing with his entire life. Thermal imaging may provide diagnostic clues that may not appear with other resources
