Resumo
The aim of this study was to evaluate in vitro the adhesion of
blood components on root surfaces irradiated with Er:YAG
(2.94??m) and GaAlAs Diode (808 nm) lasers and these effects
on irradiated root surfaces. It was obtained 100 samples of
human teeth. They were scaled and divided into five groups of 20
samples each: G1 (Control); G2 -Er:YAG laser (7.6 J/cm2); G3 - Er:YAG laser (12.9 J/cm2); G4 -Diode laser (90 J/cm2) and G5 -
Diode laser (108 J/cm2). After these treatments were conducted,
10 samples of each group received a blood tissue, and the reminiscent
10 samples did not receive such treatment. After laboratorial
treatments the samples were analysed by scanning electron
microscopy. The results have shown that there were no significant
differences between the Control Group and the groups treated
with Er:YAG laser (p=0,9633 and 0,6229); G4 and G5 were
less effective than the Control Group and the Er:YAG laser
groups (p<0,01). No proposed treatment increased the adhesion
of blood components in a significant way when compared to the
Control Group; although the Er:YAG laser did not interfere in the
adhesion of blood components it caused
more changes on the root surface, while the Diode laser inhibited
the adhesion.
