Title: The use of laser therapy in Dentistry
The current trend in dentistry is the incorporation of less invasive and innovative methods in order to minimize pain and discomfort during and after dental interventions. Thus, it is believed that laser therapy is an excellent treatment option, since it has beneficial effects on the irradiated tissues, such as microcirculation activation, vascular permeability, anti-inflammatory and analgesic effects, as well as stimulating growth and cellular regeneration. The understanding of the interaction between lasers and tissues is mainly based on the understanding of the reactions that can be induced in these tissues by laser light. This work aims to demonstrate the relevance of the physical properties of the laser as well as its interaction with the biological tissues. Low-level laser can be safely applied to accelerate the resolution of pain, cutaneous wounds and others, although this fact is closely related to the election of parameters such as doses, time of exposure and wavelengt. The quality of life improved after the sessions of laser therapy and it can be seen that the most significant changes occurred in areas related to pain, appearance, swallowing, chewing, speech, taste and salivation, corroborating for the studies that indicate low laser power as efficient tool in Dentistry.
