ABSTRACT: Aim: The aim of this in vitro study was to evaluate the presence of debris on the dentinal wall of palatal root of maxillary molars and distal root of mandibular molars after instrumentation with rotary Mtwo and Protaper Next files under stereomicroscope. Materials and Methods: Forty freshly extracted human maxillary /mandibular molar teeth were selected for this study. Teeth were divided into two groups of 20 teeth each (group A and B).Teeth were decoronated at the CEJ, palatal and distal roots were taken. In group A, all the 20 canals were subjected to cleaning and shaping with rotary Mtwo files and rotary Protaper Next files in group B. After splitting the roots longitudinally, the dentinal debris of each root canal was evaluated at three areas (coronal, middle and apical thirds of the root) by means of numerical evaluation scale, under a stereomicroscope. The data obtained were analysed statistically using Mann-Whitney Test.
Results: There was no significant difference in the debris scores between the Mtwo group and Protaper Next group in the total canal area. Conclusions: Under the condition of the present study, both the instruments Mtwo and Protaper Next rotary systems can be used to complete the preparation of canals. The use of Protaper Next instruments resulted in better canal cleanliness in the middle part compared with Mtwo.
