Abstract:

The aim of this study is to evaluate the morphological changes that may occur on the root surface with the use of hand tools, ultrasound scrapers and the Erbium-Doped Yttrium Aluminum Garnet (Er: YAG) laser. Method and Requirements: 60 teeth have been collected for periodontal reasons. The roots and roots of the teeth were removed by cutting with a diamond frez. There were two groups in each group, with 30 teeth. In the first group, the root surface refining process was done with hand tools and ulrasonic tools. In the second group, root surface refining was done with hand tools, ulrasonic tools and Er: YAG laser. The teeth were then prepared for examination with an electron microscope (SEM) scaned by drying. Foundations: In the root surface examination in the 500X extension, no advanced morphological changes were found in the root surface, such as the erosion, the formation of carbonization. In both groups, calculus was removed on the root surfaces. However, in the laser-applicated group root surface irregularities were more observed. The use of YAG laser with 160 mL/pulse, in addition to hand-to-hand tools and ultrasound scrapers, has caused much more irregularity on the root surface, although it has not caused much further damage on the root surface.
