Summary
The motor-driven lentulospiral technique showed fewer voids in primary anterior teeth obturation compared to hand-held lentulospiral and reamer methods. This suggests it offers a more efficient fill quality for dental procedures.
Area of Science:
- Endodontics
- Pediatric Dentistry
- Dental Materials Science
Background:
- Effective obturation of root canals in primary teeth is crucial for maintaining space and preventing infection.
- Voids in the root canal filling can compromise the long-term success of endodontic treatment.
- Cone-beam computed tomography (CBCT) is a valuable tool for evaluating the quality of root canal fillings.
Purpose of the Study:
- To compare the efficiency of three obturation techniques (motor-driven lentulospiral, hand-held lentulospiral, and reamer) in primary anterior teeth.
- To assess the presence, location, and size of voids using CBCT analysis.
- To determine which technique provides the most optimal fill with minimal voids.
Main Methods:
- Sixty extracted single-rooted primary teeth were prepared and obturated using Zinc Oxide Eugenol (ZOE) paste.
- Teeth were divided into three groups based on the obturation technique: Group I (motor-driven lentulospiral), Group II (hand-held lentulospiral), and Group III (reamer).
- Obturated teeth were scanned using CBCT, and the images were analyzed to evaluate void presence, location, and size.
Main Results:
- The hand-held lentulospiral technique (Group II) exhibited the highest number of voids across all locations compared to the other groups.
- Statistically significant differences in void presence were found at the coronal third and in the overall assessment (p<0.003).
- The motor-driven lentulospiral technique (Group I) demonstrated the smallest mean void size at all locations.
Conclusions:
- The motor-driven lentulospiral technique resulted in a superior quality of fill with fewer voids compared to the hand-held lentulospiral and reamer techniques.
- This technique appears to be more efficient in achieving optimal obturation in primary anterior teeth.
- CBCT analysis confirmed the effectiveness of the motor-driven lentulospiral in minimizing voids.
