| dc.description.abstract | It has been shown thot the use of both manual and rotary instruments result in the formation of o smear layer and debris during root canal treatment. The amount thot is formed depends on the type of instrumentation used as well as the force applied. Aim: The purposes of this study were. To use the scanning electron microscope to compare the cleanliness of the root canal walls following rotary and manual debridement methods 2. To assess the transportation of the apical port of the root canal orifice when using different instrumentation techniques. Materials and Methods: Endodontic treatment was performed on extracted maxillary central incisors following exportation and debridement using the Protaper@ nickel titanium files and K-files. The teeth were randomly divided into three groups. Endodontic therapy performed simulated the clinical procedures, in which the teeth were extirpated using o barbed broach to remove the necrotic pulp. Pre-operative periodical radiographs were used to determine the working length. Root canals were debrided using the two filing methods, with copious irrigation using Sodium hypochlorite solution in o disposable syringe with o 27 gauge needle. A follow up radiograph with o master apicol file in position was used to verify complete debridement in the apicol third of the canal. The teeth were then sectioned vertically using o diamond bur to create an initial groove and then split apart using q flat plastic instrument to separate the sections and to avoid contamination of the sections. These sectioned portions were then studied under o scanning electron microscope. The smear layer as well as the amount of debris was evaluated. | en_US |
