A growing trend in "cold laser" therapy involves using low-level light to stimulate cellular function. PBM is currently used to accelerate wound healing, reduce pain from TMJ disorders, and treat aphthous ulcers (canker sores). Advantages and Patient Outcomes
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. Lasers in dentistry -- current concepts
The primary driver for laser adoption is the . Lasers eliminate the whining sound and bone-shaking vibration of the drill, which are the leading causes of dental anxiety. Furthermore, because lasers seal blood vessels and nerve endings as they cut, patients typically experience less downtime and a reduced reliance on pain medication. Challenges and Future Directions A growing trend in "cold laser" therapy involves
are highly absorbed by water and hydroxyapatite, making them the gold standard for "hard tissue" procedures like cavity preparation and bone contouring. The bactericidal effect of the laser reduces the
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.
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
Despite these benefits, lasers are not a total replacement for traditional tools. They cannot be used to remove old silver (amalgam) fillings or shape teeth for certain high-precision crowns. Additionally, the high cost of equipment and the need for specialized safety training remain barriers to universal adoption. Conclusion
