Summary
The root canal anatomy of Burmese permanent maxillary first molars is complex, particularly the mesiobuccal root. Micro-computed tomography revealed intricate canal types and a high prevalence of lateral canals.
Area of Science:
- Endodontics
- Dental Anatomy
Background:
- Understanding root canal anatomy is crucial for successful endodontic treatment.
- The Burmese permanent maxillary first molar (BMFM) presents unique anatomical variations that require detailed investigation.
Purpose of the Study:
- To investigate the root canal morphology of BMFMs using micro-computed tomography (micro-CT).
- To analyze Vertucci's canal types, lateral canal incidence, isthmus characteristics, and apical foramina in BMFMs.
Main Methods:
- 101 extracted BMFMs were scanned using micro-CT.
- 3D models were reconstructed to analyze root and internal canal anatomy.
- Parameters examined included Vertucci's types, lateral canals, isthmuses, and foramina.
Main Results:
- 82.18% of mesiobuccal roots showed multiple canals, predominantly Vertucci type IV.
- Distobuccal roots mostly exhibited type I canals (86.1%), while palatal roots consistently showed type I.
- A high prevalence of lateral canals (2.38 per specimen) and apical ramifications was observed, especially in mesiobuccal roots.
Conclusions:
- BMFM root canal anatomy is complex, with significant variations in the mesiobuccal root.
- Vertucci type IV is predominant in mesiobuccal roots, while type I dominates distobuccal and palatal roots.
- Micro-CT imaging revealed complex canal configurations and a higher incidence of lateral canals than previously reported.
