简要总结
More accurate management of resorption can be achieved thanks to the three-dimensions volumetric and linear analysis, and the axial classification presented in this study.
详细描述
The aim of this study was to investigate the volumetric and linear analysis, and to present the axial classification of root resorptions using cone beam computed tomography (CBCT).
A total of 43 teeth of external cervical resorption (ECR) (n=27), external replacement resorption (ERR) (n=4) and internal root resorption (IRR) (n=12) were identified from 34 patients. The volume of resorption and total tooth, the widest lengths of these resorptions, and the amount of thinnest dentin thickness around them were measured and compared according to age and sex. Additionally, the eight regional axial classification was performed and the percentages in these regions were evaluated. Significance was set at p=0.05 for statistical analysis.
More accurate management of resorption can be achieved thanks to the three-dimensions volumetric and linear analysis, and the axial classification presented in this study.

入选标准
- •Cases of resorption that had CBCT images
排除标准
- •those presenting pathologic lesions, congenital/developmental anomalies or teeth with root canal filling
- •those whose CBCT scans failed to present satisfactory quality.
- •Additionally, SR, TAP, and EIR cases were excluded because their true dimensions could not be completely determined before resorption.
