Summary
Maxillary lateral incisors, typically single-canal, can rarely exhibit two root canals. This finding highlights the importance of considering anatomical variations in endodontic diagnosis and treatment.
Area of Science:
- Endodontics
- Dental Anatomy
- Morphology
Background:
- Root canal morphology exhibits significant variability.
- Maxillary lateral incisors are generally described as having a single root canal.
- Anatomical anomalies in these teeth are considered rare in dental literature.
Observation:
- This report details two clinical cases.
- Both cases involved maxillary lateral incisors.
- Each presented with an unusual two-canal root system.
Findings:
- The study identified two instances of maxillary lateral incisors with double root canals.
- This challenges the established understanding of their typical anatomy.
- Confirms that root canal variations can occur even in teeth with low anomaly frequency.
Implications:
- Clinicians must consider the possibility of complex root canal anatomy in maxillary lateral incisors.
- Thorough endodontic evaluation is crucial for successful treatment.
- These findings may necessitate revised diagnostic protocols for maxillary lateral incisors.
