For periodontal (gum) therapy, lasers are used to decontaminate diseased pockets and remove inflamed tissue. The bactericidal effect of the laser reduces the need for systemic antibiotics and significantly minimizes post-operative swelling and bleeding.
The use of lasers in dentistry has transitioned from a futuristic novelty to a cornerstone of modern clinical practice. By utilizing focused light energy, lasers offer a minimally invasive alternative to traditional mechanical tools like the high-speed drill and the scalpel. Current concepts in dental laser technology revolve around increasing patient comfort, enhancing precision, and promoting faster healing through the targeted interaction of light with biological tissues. The Mechanism of Action
Lasers can remove decay and prepare enamel for fillings often without the need for local anesthesia. Unlike the vibration and heat of a drill, lasers use "micro-explosions" of water molecules to remove tissue, which preserves more of the healthy tooth structure. Lasers in dentistry -- current concepts
At the heart of dental laser application is the concept of . Different laser wavelengths are absorbed by specific "chromophores" in the mouth, such as water, hydroxyapatite (the mineral in teeth), or hemoglobin.
Modern dentistry categorizes laser use into three primary domains: For periodontal (gum) therapy, lasers are used to
are primarily absorbed by hemoglobin and melanin, making them exceptionally efficient for "soft tissue" surgeries, such as gingivectomies, where they provide simultaneous cutting and cauterization. Current Clinical Applications
are highly absorbed by water and hydroxyapatite, making them the gold standard for "hard tissue" procedures like cavity preparation and bone contouring. By utilizing focused light energy, lasers offer a
Current concepts in dental lasers emphasize a shift toward "biological dentistry"—procedures that are less traumatic and more conducive to the body’s natural healing processes. As technology advances and units become more affordable, lasers are set to become as common as the dental chair itself, redefining the standard of care through precision and comfort.
