Lasers are being used as screening instruments to help diagnose dental illness at an earlier level than conventional approaches. Pit and fissure erosion can be diagnosed by laser fluorescence diagnostic lasers, which can penetrate locations on the biting surfaces of teeth that a typical dental explorer, such as a needle-like pointing instrument, can’t.
Fluorescence is a glowing light that can be seen by a laser detector due to the optical properties of bacteria in decayed teeth. They are a valuable addition to oral exams, assisting in the detection of caries that would otherwise be overlooked by visual observation alone. They also enable teeth to be tracked from one visit to the next, allowing dentists to assess if decay is “arrested” or “progressive,” and thus when care is genuinely required.
Dental calculus under the gums can also be detected and localized using lasers. Calculus, also known as tartar, is a bacterial plaque that has dried or calcified and adheres to the teeth. One of the purposes of periodontal (gum) treatment is to locate and remove this calculus.
Lasers that “fluoresce” healthy oral soft tissue have recently been created. Lasers are being used to diagnose oral cancer at an early stage by distinguishing areas that fluoresce and those that don’t. They also help in the diagnosis and localization of irregular tissues by identifying areas that glow and those that don’t.
Lasers are particularly effective for cutting tissue near the borders or edges of where diseased tissue approaches healthy tissue because of their accuracy. This precise and minimally invasive technique is especially helpful in assessing these limits and precisely where abnormal tissue, whether benign or malignant, can be removed or excised. This indicates that how important the role of lasers has been in the diagnosis of dental illnesses.
