CAVALCANTI, Thiago Maciel et al. Knowledge of the physical properties and interaction of laser with biological tissue in dentistry. An. Bras. Dermatol. [online]. 2011, vol.86, n.5, pp.955-960. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962011000500014.
The trend in dentistry is to incorporate less invasive methods to minimize pain and discomfort during and after dental intervention. Therefore, it is believed that laser therapy is an excellent treatment option, since it has beneficial effects for the irradiated tissues, such as activation of microcirculation, production of new capillaries, inflammatory and analgesic effects, in addition to stimulation of growth and cell regeneration. The comprehension of the interaction between lasers and tissue is based mainly on understanding the reactions that can be induced in those tissues by laser. This work intends to show how important it is to know the physical properties of laser as well as its interactions with biological tissues, since its effects and mechanisms of action are complex and are the object of various studies to better understand its forms of application and indications.
