Precision dentistry leverages cutting-edge technologies, with lasers emerging as a powerful tool in dental procedures for enhanced accuracy and efficiency. Laser dentistry offers a minimally invasive approach, allowing for more precise tissue removal while minimizing damage to surrounding healthy structures. The laser advantage in precision dentistry extends to various applications, including cavity preparation, soft tissue surgeries, and periodontal treatments. Lasers enable dentists to perform procedures with increased control, reducing the need for anesthesia in some cases and enhancing patient comfort. The pinpoint accuracy of lasers facilitates selective removal of diseased tissues, promoting conservative and targeted dental interventions. Precision with lasers also contributes to faster healing times, as the technology minimizes trauma to the treated areas, reducing post-operative discomfort. Dental lasers find utility in cosmetic dentistry, allowing for precise shaping of gum tissues, teeth contouring, and teeth whitening procedures.
Ringkasan
- Dr. Madvi Shetti, an endodontist, discusses the use of lasers in endodontics and conservative dentistry. Lasers have various applications outside of dentistry, including in CD players, printers, and medical fields like ophthalmology and aviation, and tattoo removal. Laser energy is precise and avoids fractures, and a laser transforms light of various frequencies into chromatic radiation.
- The history of lasers includes Newton's characterization of light as particles, Maxwell's concept of electromagnetic radiation, Einstein's theory of wavelength, and the first laser developed by Theodor Maiman, utilizing Ruby rods. Lasers are classified based on output energy (low/soft/therapeutic, high/hard/surgical), state of gain medium (solid state, gas, aymer, diode), and oscillation mode (continuous wave, pulse wave).
- Advantages of lasers in dentistry include reduced anxiety, less noise, potential for needle-free dentistry, and faster healing, whereas disadvantages involve slower enamel removal, potential cumbersome use compared to high-speed handpieces, and an inability of some laser types to remove gold and amalgam.
- Key laser terminologies include wavelength, modes of operation, pulse energy, repetition rate, pulse width, thermal relaxation time, laser power, spot size, and fluence. Laser wavelengths near infrared are poorly absorbed by dental mineral, while the absorption increases at the blue end and into ultraviolet regions. Lasers' interaction with tissues involves photochemical, photothermal, photoch mechanical, and photoelectrical processes.
- Different types of lasers used in dentistry are argon, diode, Nd:YAG, holmium:YAG, erbium family, and CO2, each having unique properties and applications. Laser applications in conservative dentistry include diagnosis, carries prevention, cavity preparation, bonding, curing composites, alleviating dental hypersensitivity, and bleaching.
- Laser Doppler flowmetry assesses blood flow for pulp diagnosis, using helium-neon and diode lasers at low power. Pulp capping and pulpotomy involve preserving the pulp by encouraging dentin formation. Cleaning root canal systems involves optical fibers for irrigation and disinfection, and PIPS (photoacoustic streaming) enhances cleaning solutions.
- Laser safety involves manufacturing, proper operation, and personal protection, with lasers classified from Class 1 to Class 4 based on hazard potential. Appropriate laser safety glasses are essential due to the potential for serious eye and skin damage, and fire and explosion hazards.
