Lasers have been used in dentistry since the 1960s, with applications in prosthodontics, pre-prosthetic surgery, implantology, and forensic dentistry. They are categorized into soft and hard lasers, including CO2, Nd, and diode lasers. Lasers offer precision in tissue treatment, minimize bleeding, reduce tissue shrinkage, and are used for welding dental materials like titanium. In implantology, lasers enable immediate impression-taking after surgery and reduce tissue trauma. Safety precautions are essential for operators during laser procedures.
