Introduction: The tooth root surfaces are modified by different agents for better removal of the smear layer, the formation of fibrin clots, and the attachment of blood cells. This in vitro study compared the removal of the smear layer, the formation of fibrin clots and the attachment of blood cells after exposing periodontally compromised root surfaces to ER:YAG and CO2 laser beams. Methods: Eighteen dentin block samples were prepared from freshly extracted periodontally compromised teeth that were deemed hopeless, and they were divided into 3 groups: exposed to Er:YAG laser beams, exposed to CO2 laser beams, and the control group. The samples were evaluated using scanning electron microscopy and micrographs were taken. Smear layer removal and blood cell attachment were scored. Data were analyzed using Kruskal-Wallis and MannWhitney tests. Results: In the Er:YAG laser group, the smear layer was removed completely. In the specimens exposed to blood, better fibrin clot formation and blood cell attachment were observed in the Er:YAG laser group. In the CO2 laser group, the smear layer was also removed; however, there were no significant differences between the CO2 laser and control groups in fibrin clot formation and blood cell attachment. Conclusion: The application of the Er:YAG laser to the root dentin appears to result in the formation of a suitable surface for fibrin clot formation and blood cell attachment. Further clinical studies are necessary to support these results.

ABSTRACT Objectives Erstwhile studies have emphasized the importance of establishing a secure fibrin linkage between the tooth-soft tissue interface for formation of a new connective attachment. Thus, periodontal regeneration is reliant on the constant adhesion, maturation and absorption of fibrin clots to the root surfaces which are compromised periodontally. Improved fibrin clot formation and blood cell attachment is being aimed by modification of the root surfaces with different agents. Limited studies have evaluated the attachment of blood cell component on various laser treated root surfaces individually. Hence, the aim of this in vitro study was to evaluate and compare the adhesion of blood components on the root surfaces treated with citric acid, Nd:YAG, Er:YAG and CO2 lasers by scanning electron microscopy (SEM). Materials and methods The proposed study was conducted on 35 root specimens (5 × 5 × 1 mm) obtained from extracted periodontally compromised permanent teeth. The root specimens were randomly divided in five groups depending upon the type of treatment rendered. Group I: Untreated control group, group II: Citric acid (pH:1), group III: Nd:YAG laser (112.5 m J/pulse), group IV: CO2 laser (12.5 J/cm2), group V: Er:YAG laser (120 m J). Following the respective treatments, fresh human whole peripheral blood obtained from a healthy donor was applied to the external surface of all root specimens. The specimens were then analysed and scored for the adhesion of the blood components with photomicrographs of SEM. Results Statistically significant increase in the adhesion of blood components was seen in all the test groups compared to control group both citric acid and Er:YAG laser showed higher adhesion of blood cells to the root surface than the Nd:YAG laser and CO2 laser. Conclusion Er:YAG laser enhanced the adhesion of blood components over the treated root surfaces. Hence, it can be safely used as a root bio-modifier ensuring stable fibrin linkage to promote periodontal regeneration. How to cite this article Sabnis S, Gayathri GV, Chandra KK, Mehta DS.
