Resumo
Objective: The aim of this study was to evaluate in vitro, by scanning electron
microscopy (SEM), the adhesion of blood components on root surfaces irradiated
with Er:YAG (2.94 lm) and GaAlAs Diode (808 nm) lasers and the effects on the
morphology of irradiated root surfaces.
Methods: One hundred samples of human teeth were obtained. They were previously planed and scaled with manual instruments and divided into five groups of
20 samples each: G1 (control group) – absence of treatment; 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, 10 samples of each group
received a blood tissue but the remaining 10 did not. After laboratory treatments,
the samples were obtained by SEM, the photomicrographs were analysed by the
score of adhesion of blood components and the results were statistically analysed
(Kruskall–Wallis and Mann–Whitney test).
Results: In relation to the adhesion of blood components, the study showed no
significant differences between the control group and the groups treated with
Er:YAG laser (p ¼ 0.9633 and 0.6229). Diode laser radiation was less effective
than control group and Er:YAG laser radiation (p < 0.01).
Conclusions: None of the proposed treatments 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, whereas the Diode laser inhibited the adhesion.
