Management of Root Perforations Using MTA with or without Er:YAG Laser Irradiation: An In Vitro Study

<table>View of the dentine conditioned by Er:YAG laser (group ML), the Er:YAG laser had removed the smear layer. The tubules are totally opened. The Er:YAG laser produced a selective and preferential ablation of intertubular dentine, while the peritubular dentine (higher mineralization) was less ablated. Magnification: 5000x. Scale bar = 1 <i>μ</i>m.</table>
