Summary
The dental operating microscope (DOM) significantly enhances root canal detection in mandibular molars. This advanced visualization tool increases the number of located root canal orifices, improving endodontic treatment planning.
Area of Science:
- Dentistry
- Endodontics
- Microscopic Imaging
Background:
- Locating all root canal orifices is crucial for successful endodontic treatment.
- Mandibular molars present anatomical complexities that can obscure canal openings.
- Traditional methods may not always reveal all accessory canals or orifices.
Purpose of the Study:
- To evaluate the efficacy of the dental operating microscope (DOM) in identifying additional root canal orifices in mandibular molars.
- To quantify the increase in located canals when using magnification compared to the naked eye.
Main Methods:
- Ninety-three extracted mandibular first molars and 111 second molars were analyzed.
- Access cavities were prepared and canals counted using the naked eye.
- The same teeth were re-examined under a DOM at x8-x13 magnification to identify additional canals.
Main Results:
- A total of 641 canals were initially observed with the naked eye.
- The DOM examination revealed 50 additional canals, a 7.8% increase in detection.
- Of the newly identified canals, 35 were in first molars and 15 in second molars.
Conclusions:
- The dental operating microscope significantly increases the number of detectable root canal orifices in mandibular molars.
- Enhanced visualization with DOM improves the thoroughness of root canal detection.
- DOM use is recommended for comprehensive endodontic evaluations of mandibular molars.
