Abstract Background This study aims to determine the smear layer removal from root canals using different irrigant solutions with diode laser. Methods A set of sixty human upper incisor teeth were chosen. Access cavity preparation was done followed by canal instrumentation. Samples divided into six groups (Group A: sodium hypochlorite NaOCl, Group B: NaOCl + laser, group C: EDTA ethylene diamine tetra-acetic acid solution, D: E: garlic extract, F: extract Examining at coronal, middle and apical thirds electron microscope analysis. Using an energy-dispersive X-ray, calcium/phosphorus Ca/P ratio measured. Results Among examined groups, there not any significant differences regarding removal. The elimination layers coronal greater in all than third. EDX analysis revealed no statistically variation between tested groups. Conclusions laser solution more effective for layers. Garlic could be used as alternative debris
