Root Canal Therapy: Why Are ProTaper Rotary Files Important?
Root Canal treatment is used to treat an infected or inflamed pulp of a tooth. In it, the elimination of debris/infection is conducted using various endodontic techniques. Moreover, the protection and decontamination of the affected area are also done to prevent further infection/debris pile-up.
The Importance of ProTaper Rotary Files in Root Canal Therapy:
Compared to traditional filing systems, ProTaper rotary files have a fixed taper. Each endodontic ProTaper file hones a changing taper with a helical angle and pitch on the cutting blade themselves.Due to its curvature, this reduces the risk of the instrument getting screwed into the canal. Moreover, every ProTaper rotary file has a non-cutting guiding tip which helps the instrument follow the safe portion in root canal therapy. The small flat edge present at the tip allows the instrument to be better guided through debris, helping find the apex of the tooth much quicker and reducing overall steps and fractures by a significant margin.Performance Requirements for ProTaper Rotary Files
Considered as the future of endodontics, ProTaper rotary files have some stringent requirements that must be taken into account. And these points are a part of the ProTaper endodontic filing system’s design:- Torsional Loads: Under equal loads, ProTaper rotary file systems show the lowest amount of stress leading to a reduction in the number of steps and inadvertent screwing.
- rotary endodontic files with good fatigue resistance can avoid medical accidents caused by broken rotary files.
- Cross-Sectional Design: ProTaper files have a continuously changing pitch and helical angles over the active length of their blades which helps improve their cutting action. Moreover, its progressively tapered design prevents each instrument from screwing into the canal as well. At present, the cutting efficiency of the triangular cross-section is relatively high.
