Abstract | Recently, the Er:YAG and CO2 lasers have been
applied in periodontal therapy. However, the characteristics
of laser-irradiated root cementum have not been fully analyzed.
The aim of this study was to precisely analyze the
alterations of root cementum treated with the Er:YAG and
the CO2 lasers, using non-decalcified thin histological sections.
Eleven cementum plates were prepared from extracted
human teeth. Pulsed Er:YAG laser contact irradiation was
performed in a line at 40 mJ/pulse (14.2 J/cm2/pulse) and
25 Hz (1.0 W) under water spray. Continuous CO2 laser
irradiation was performed in non-contact mode at 1.0 W,
and ultrasonic instrumentation was performed as a control.
The treated samples were subjected to stereomicroscopy,
scanning electron microscopy (SEM), light microscopy
and SEM energy dispersive X-ray spectroscopy (SEMEDS).
The Er:YAG laser-treated cementum showed minimal
alteration with a whitish, slightly ablated surface,
whereas CO2 laser treatment resulted in distinct carbonization.
SEM analysis revealed characteristic microirregularities
of the Er:YAG-lased surface and the melted,
resolidified appearance surrounded by major and microcracks
of the CO2-lased surface. Histological analysis
revealed minimal thermal alteration and structural degradation
of the Er:YAG laser-irradiated cementum with an affected
layer of approximately 20-μm thickness, which
partially consisted of two distinct affected layers. The
CO2-lased cementum revealed multiple affected layers
showing different structures/staining with approximately
140 μm thickness. Er:YAG laser irradiation used with water
cooling resulted in minimal cementum ablation and thermal
changes with a characteristic microstructure of the superficial
layer. In contrast, CO2 laser irradiation produced severely
affected distinct multiple layers accompanied by
melting and carbonization. | pt_BR |
