Introduction:
The present study aims to evaluate the root canal morphology of permanent lower incisors by cone-beam computed tomography (CBCT) according to Vertucci's classification (1984), and to correlate the findings with sex, age group, and side of the dental arch.
Materials And Methods:
This was a descriptive observational study that used a sample of mandibular CBCT scans performed between 2021 and 2024 at a private dental radiology service. When none of the Vertucci configurations was applicable, type 0 was assigned.
Results:
Type I was the predominant morphological configuration, followed by type III, for all variables analyzed. Regarding sex, type I was more common among females (71.1%), while type III accounted for 21.2% in both males and females. With respect to age, type I was more common among minors (76.8%), and type III among older adults (23.3%). The type I configuration was more frequently observed on the right side of the dental arch (70.3%), and type III on the left side (21.9%).
Conclusion:
The anatomical observations of the lower incisors highlight the need for careful analysis of their internal morphology during endodontic treatment.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
