Description
Lasers are used for various soft tissue procedures like gum contouring, frenectomy, and removal of oral lesions with minimal bleeding and postoperative discomfort. They can effectively remove dark patches or pigmentation from the gums to enhance esthetics. Laser-assisted periodontal therapy can help remove infected tissue and promote gum reattachment in cases of gum disease. They can be used to remove decayed tooth structure, reducing the need for traditional drilling and preserving more healthy tooth material. Dental lasers can help alleviate tooth sensitivity by sealing open dentinal tubules and reducing nerve exposure. Laser-assisted teeth whitening procedures can accelerate the bleaching process, enhancing the effectiveness of in-office whitening treatments. Lasers can precisely remove tooth structure for dental restorations and cavity preparations, minimizing discomfort for patients.
Résumé
- Lasers in dentistry have evolved significantly since their initial exploration in the 1960s, encompassing a range of wavelengths and applications. They operate on the principle of light amplification by stimulated emission of radiation (LASER), relying on the stimulated and spontaneous emission of photons. Key to laser function is the interaction with tissue chromophores, which absorb light at specific wavelengths, leading to different tissue effects like absorption, transmission, scattering, and reflection.
- Understanding laser physics is crucial for effective implementation in dental practice. Lasers can be broadly categorized as soft tissue, all-tissue, low-level, and diagnostic, each possessing unique characteristics. Soft tissue lasers typically range from 445 to 1064 nanometers, while all-tissue lasers span from 1064 to 10,664 nanometers.
- Laser tissue interaction can lead to various biological effects, including photochemical, photobiomodulating, photothermal, and photodisruptive actions. This results in responses such as long-term healing, delayed responses, and immediate physical effects. The desired laser-tissue interaction includes efficient cutting or ablation with sufficient hemostasis and coagulation. Diode lasers require tip initiation for effective cutting, utilizing a hot tip to incise the tissue.
- Practical applications of lasers in dentistry are extensive, including gingival recontouring, crown lengthening, frenectomies, gum depigmentation, non-surgical periodontal treatment, and biopsies. Different wavelengths and settings are suitable for each procedure. Diode lasers, for instance, are versatile for soft tissue procedures, while erbium family lasers are favored for all-tissue applications.
- Laser safety is paramount, requiring the designation of a laser safety officer (LSO) and comprehensive training for personnel. Essential safety measures include wearing appropriate laser protective eyewear, controlling access to the laser beam, and implementing warning signs. Maintaining accurate records of training and audits are critical for compliance and a safe environment.
