Summary
Hand instruments provided superior root canal preparation smoothing compared to engine-driven systems. One engine-driven system (3-LD) showed limited utility in specific cases, while another (3-LDSY) was inefficient.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Root canal preparation is crucial for endodontic treatment success.
- Evaluating novel engine-driven instruments is essential for improving clinical outcomes.
Purpose of the Study:
- To compare the efficacy of hand instruments versus two engine-driven instruments for root canal preparation.
- To assess the surface smoothness of root canal walls achieved by different preparation methods.
Main Methods:
- Extracted teeth underwent root canal preparation using hand instruments, KaVo Intraendokopf 3-LDSY, or 3-LD engine-driven instruments.
- Prepared root canals were examined using light and scanning electron microscopy.
Main Results:
- Hand instruments yielded the smoothest root canal walls.
- The 3-LD instrument demonstrated utility in specific challenging canal anatomies.
- The 3-LDSY instrument exhibited binding issues, preventing full working length achievement.
Conclusions:
- Manual root canal preparation remains the gold standard for achieving smooth canal walls.
- Engine-driven instruments offer potential benefits but require careful selection and application.
- Further research is needed to optimize engine-driven instrumentation for diverse root canal morphologies.
