Summary
The Mecasonic system with Shaper files demonstrated the highest dentin removal efficiency in 1 minute. For 2-minute instrumentation, the Cavi-Med with Shaper files was most effective, highlighting system and file type impact.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Efficient dentin removal is crucial for successful root canal treatment.
- Current endodontic systems vary in their dentin removal capabilities.
- Optimizing instrumentation time and technique is essential for predictable outcomes.
Purpose of the Study:
- To compare the dentin removal efficiency of six different endodontic systems.
- To evaluate the impact of instrumentation duration (1 and 2 minutes) on efficiency.
- To assess the influence of file type and activation mode on dentin removal.
Main Methods:
- Six endodontic systems were tested: Giromatic, Sonic-Air, Mecasonic, Cavi-Med (with K files and Shapers), and Excalibur.
- Dentin removal was quantified per 1 mm of canal axial length.
- Systems were evaluated for working times of 1 and 2 minutes.
Main Results:
- The Mecasonic system with Shaper files was most efficient at 1 minute.
- The Cavi-Med system with Shaper files showed the highest efficiency at 2 minutes.
- Ultrasonic Shaper files were more effective than K files; Excalibur and Mecasonic systems showed comparable sonic efficiency.
Conclusions:
- Endodontic system efficiency is dependent on instrumentation duration, file type, and activation mode.
- The Mecasonic and Cavi-Med systems, particularly with Shaper files, offer high dentin removal efficiency.
- Shaper files demonstrate superior performance in ultrasonic applications compared to K files.
