Aim: 1. To evaluate the gutta percha removal using Rotary Retreatment Files And Nd:YAG laser. Materials and Method: 20 extracted single rooted teeth were selected for the study. Cleaning and shaping were done till rotary protaper F3. The teeth were obturated using gutta percha and zinc oxide eugenol. The teeth were randomly divided into 2 groups: Group A: Gutta percha removal with Protaper Rotary Retreatment Files Group B: Gutta percha was softened using Nd:YAG laser and then removed with Protaper Rotary Retreatment Files. The teeth were then sectioned using a chisel and mallet. The sectioned teeth were analysed for the guta percha remaining using MVI500 software (Chroma systems) and stereomicroscope
