Summary
Dynamically navigated access preparations for root canals are faster and more precise, resulting in less tooth structure loss compared to traditional freehand methods in simulated calcified canals.
Area of Science:
- Endodontics
- Dental Technology
- Minimally Invasive Dentistry
Background:
- Root canal access preparation is crucial for endodontic treatment success.
- Calcified root canals present a significant challenge in locating the canal orifice.
- Traditional freehand techniques may lead to increased tooth structure removal and procedural errors.
Purpose of the Study:
- To compare the speed, precision, and tooth structure loss between freehand and dynamically navigated access preparation techniques.
- To evaluate these techniques in simulated calcified root canals using 3D-printed teeth.
Main Methods:
- Forty 3D-printed central incisors with simulated calcified canals were used.
- Access preparations were performed using freehand and dynamically navigated techniques.
- Postoperative cone-beam computed tomographic scans assessed qualitative precision and quantitative tooth structure loss.
Main Results:
- Dynamically navigated accesses showed significantly less mean substance loss (27.2 vs 40.7 mm³).
- Optimal precision was higher with dynamic navigation (75% vs 45%).
- Dynamically navigated accesses were prepared significantly faster (2.2 vs 7.06 minutes).
Conclusions:
- Dynamically navigated access preparations offer significant advantages over freehand techniques for locating simulated anterior calcified root canals.
- This technique leads to reduced tooth structure loss and improved efficiency.
- The findings suggest potential for enhanced precision and conservation in endodontic access preparations.
