Abstract

In recent years, the desire of Dental Clinicians and patients to use lasers for the treatment of Dental conditions has increased. Knowledge of laser functions and biological features of oral tissues is crucial for understanding the effect of dental lasers. Choosing a suitable dental laser for different tissues effectively reduces tissue damage. Other types of lasers are used in dentistry, which effectively treats lesions by providing innovative and minimally invasive treatments that also have biostimulation, anti-inflammatory, and analgesic effects. Among lasers, erbium lasers, being less invasive and having caries removal properties, have been optimally considered in pediatric dentistry. Lasers in children can also have efficient antiseptic effects on vital and non-vital pulp therapies of primary teeth. One of the most common oral problems in children is dental trauma. Laser-based therapies can significantly reduce pain and surgical problems. Laser therapy is a suitable and valuable treatment strategy in children despite surgery problems and provides practical health solutions. Findings have shown that different lasers, based on their wavelength, can cause incisions on the soft and hard tissues of the mouth and teeth in the form of various mechanisms such as vaporisation or ablation, and these effects vary according to the wavelength used; however, choosing an infrared laser allows the dentist to better interact with specific targets such as gums, mucous membranes, and mouth injuries. This chapter examines the critical effects of lasers in pediatric dentistry.
