Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Oral and Dental Medicine - Department of Endodontics Summary: Aim To determine the shaping ability and cleaning effectiveness of Revo-S and Typhoon CM wire rotary instruments in-terms of degree and direction of canal transportation. Methodology Mesiobuccal canal of 70 extracted maxillary molars were divided into 2 groups of 35 teeth each and were then prepared using Revo-S and Typhoon CM wire rotary instruments after all teeth showed the following criteria, mesiodistal (clinical) canal curvature range between 25{u00BA}- 40{u00BA}, the radius of curvature of the canal range from 4 - 10 mm, the length of the curved part of the canal between 6 - 8 mm. Pre- and post-instrumentation measurements of root dentine thickness for 40 teeth were assessed using CBCT to determine degree of transportation and centering ability while 30 teeth were assigned for evaluation of cleanliness using stereomicroscope and SEM. Thirty samples (15 from each group) were observed under stereomicroscope for gross detection of the dentin surface. Five samples from each group were randomly selected for examination of smear layer under SEM
