Dental lasers offer various applications for soft and hard tissues, but they do not replace conventional dental tools. Dentists should understand laser types and scientific evidence before purchasing.

Area of Science:

  • Dentistry
  • Biomedical Engineering

Background:

  • Lasers have gained significant attention in dental practices over the past two decades.
  • Both soft-tissue (e.g., frenectomy, gingival contouring) and hard-tissue (e.g., caries removal, bleaching) applications have been explored.
  • Patient demand and perception may influence dentists' adoption of laser technology.

Purpose of the Study:

  • To describe different types of dental lasers.
  • To examine the scientific basis for laser applications in dentistry.
  • To inform dentists about the efficacy and limitations of laser technology.

Main Methods:

  • Review of scientific literature on dental laser applications.
  • Analysis of soft- and hard-tissue procedures using lasers.
  • Discussion of the scientific evidence supporting various dental laser uses.

Main Results:

  • Lasers have demonstrated utility in specific dental procedures.
  • Understanding the differences between various laser types is crucial.
  • Scientific literature provides insights into the applications and limitations of dental lasers.

Conclusions:

  • Lasers are valuable adjuncts in dentistry but do not substitute for traditional instruments.
  • Dentists must possess a thorough understanding of laser technology and its scientific backing.
  • Informed decision-making regarding laser investment is essential for effective clinical practice.
