Resumo
Various laser systems have been used in treatment of hard tissue with efficiency and safety. The action of the
Nd:YAG laser in caries prevention has been reported for many research groups. Caries is a bacterial disease
that affects a significant part of world population, causes minerals reduction and may lead to a total loss of
the dental tissue. The aim of this study was to evaluate the use of short pulses Nd:YAG laser in caries prevention. The dependency between physico-chemical parameters like hardness and the mineral composition
of dental enamel is outlined. Thirty human enamel samples were divided into two groups. The laser used
emits radiation wavelength of 1.064 nm, energy of 73 mJ per pulse and 10 ns of pulse width. X-Ray
Fluorescence, SEM and Vickers microhardness techniques were used. Obtained results are consistent with
other studies and indicated greater Ca/P ratio in lased groups in comparison to the unlased group. The present
study suggests that the use of the Q-Switched- d:YAG laser in enamel surfaces contributes to increase
the hardness and decrease the mineral loss by bacterial acid attack.
