Aim:
To investigate the prevalence, severity, and predictors of apical root resorption following orthodontic treatment using cone-beam computed tomography (CBCT).
Methods:
A retrospective analysis was conducted on the CBCT scans of 141 orthodontic patients (76 males and 65 females). CBCT images were meticulously assessed for the presence and severity of apical root resorption using standardized grading criteria.
Results:
The prevalence of apical root resorption was 45.4%. Among those with root resorption, 35.5% exhibited grade 1 resorption, while 10.8% showed grade 2 resorption. Sex was not significantly associated with the severity of root resorption (P = 0.312); however, age had a significant effect (P < 0.05). Younger age groups were more prone to severe root resorption. Additionally, the treatment duration was significantly correlated with the severity of root resorption (P = 0.021), with longer treatment durations associated with increased resorption severity.
Conclusion:
This study provides valuable insights into the prevalence, severity, and predictors of apical root resorption following orthodontic treatment using CBCT imaging. These findings highlight the importance of considering patient demographics and treatment duration in treatment planning to mitigate the risk of root resorption and enhance treatment outcomes.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

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...
