• Preoperative assessment: Begin by conducting a thorough examination of the patient's dental condition, including diagnostic imaging (X-rays) and clinical evaluation, to determine the appropriate treatment plan and identify the root canals that need to be addressed.• Access preparation: Use conventional methods to create access to the pulp chamber, ensuring proper visibility and adequate space for instrument insertion.
• Working length determination: Accurately measure the working length of each canal using an apex locator or radiographic techniques. This step is crucial for determining the appropriate file length and preventing over-instrumentation.
• Glide path creation: Establish a glide path using hand files or dedicated glide path files. This step helps facilitate the safe and smooth insertion of the rotary files and reduces the risk of file separation.
• Irrigation and disinfection: Prior to using the rotary files, thoroughly irrigate the canal with an antimicrobial solution to disinfect the area and remove debris. This step is crucial for maintaining a clean and sterile working environment.
• File selection: Choose the appropriate MTG PRO Hand or Rotary File based on the canal anatomy, size, and curvature. The system typically includes a series of files with different tapers and tip sizes, designed for specific tasks during canal shaping and finishing.
• File sequence: Follow the recommended file sequence provided by DPI which typically involves progressively using the files from the larger to the smaller sizes. This sequence allows for effective and efficient shaping of the canal while minimizing the risk of instrument fracture.
• Mechanical preparation: Insert the selected file into the canal using a slow-speed handpiece or an endodontic motor with the recommended settings. Use a gentle pecking motion and avoid excessive pressure to prevent file binding or ledge formation.
• Irrigation and file cleaning: Regularly irrigate the canal during instrumentation to flush out debris and lubricate the area. This helps prevent file blockage and enhances the efficiency of the rotary files.
