وصف
Rotary endodontics includes an electrically powered instrument which performs the root canal treatment and replaces the traditional stainless- steel manual files. The tip of the hand tool is used out of nickel titanium,it is more flexible than traditional stainless steel. The instrument that enables dental health professionals to remove or reduce the tooth matter, dental materials and to shape during the procedures. The steps for endodontics treatment includes diagnosis, access, extirpation, debridement, drying, obturation and the restoration.

- Rotary endodontics simplifies cleaning and shaping root canals compared to traditional 2% file methods. It offers greater speed, ease, and accuracy, which can facilitate easier obturation. A learning curve exists, particularly because undergraduate dental programs often lack sufficient training in rotary techniques.
- Dental knowledge gaps exist, especially concerning advanced procedures like rotary endodontics and implants. Postgraduate courses are often necessary to bridge this gap and provide practical experience. Starting with extracted teeth is crucial for mastering access opening and canal location before treating patients.
- Common complications include ledge formation due to skipping glide path steps, perforations from improper canal location, and excessive dentin removal. Following recommended file sequences and using hand files for initial negotiation is essential to avoid these issues. Regular patency maintenance with hand files is also important.
- Sinus tracts with openings may allow for single-visit root canal treatments, while multiple visits are required if swelling must subside first. The two percent files are used to negotiate the canal. The orifice open-off technique improves canal visibility. Four and six percent rotary files are used for shaping and cleaning.
- The apical diameter dictates the need for four or six percent files, starting with hand files is important, particularly in narrow canals. Different rotary file systems have varying sequences and specifications (RPM, torque), requiring familiarity with a few preferred systems and extracted tooth practice before patient use. Calcified canals should be negotiated with hand files initially.
- Hand files must be used, especially C and D-finders, to create a glide path before introducing rotary instruments, even in calcified canals. Hand protapers are invaluable in gaining the tactile sensation needed. Rotary endodontics simply aids in the cleaning and shaping, it is not required. There are many different files in the market to use.
- GP selection involves achieving a "tub bath" at the apex for proper seal. The last file size used is usually the proper cone size. Tourque and RPM are set according to the manufacturer's instructions. Periapical bleeding, assuming no perforation, could arise from pulp tissue, missed canals, or improper access opening, necessitating thorough exploration and cleaning.
- Rotary endodontics is not obligated in every canal. Root canals can successfully be performed using hand files, rotary endodontics just helps. A file going beyond the apex in the PA area, requires the adjacent roots be adequately treated. It also will require clinical judgment and anti-inflammatory drugs, or surgical means to recover tooth and pain issues. The file may also be inert and the body might encapsulate it.
- The re-treatment success rate has a success rate is reduced tenfold. Retreatment is easier if zinc oxide cement was used, since resin cement is difficult to remove. Resin based sealer as just a sealer, there are just as many positives and negatives to both, and is a preferred material for most.
