ABSTRACT
<p><b>OBJECTIVE</b>To observe the morphological transformation and Ca/P changes of the periodontally disease root surfaces irradiated by Er, GrYSGG Laser.</p><p><b>METHODS</b>18 periodontally diseased teeth and 6 wisdom teeth were collected in vitro. After 18 periodontally diseased teeth were planed, 12 teeth were randomly selected as the laser treatment group, the others as the acid treatment group. The 6 wisdom teeth were selected as the healthy control. Then the evaluation for root surfaces morphological transformation was conducted by SEM. An energy spectrum analyzer was used to analyze the Ca/P ratio of root surfaces.</p><p><b>RESULTS</b>The root surfaces were clean and even in the laser treatment group. Smear layer could also be effectively eliminated in the laser treatment group and the acid treatment group, but the SEM results were different. Atom content analysis showed that the Ca/P ratio of the laser treatment group and the acid treatment group had no distinct difference.</p><p><b>CONCLUSION</b>It is effective to remove smear layers and infected cementum of surface layers with Er, CrYSGG irradiating on the planed periodontal root surfaces.</p>
