Clinical Trial Summary

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.

Description:

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.

Eligibility

Inclusion Criteria:

• Cases of resorption that had CBCT images

Exclusion Criteria:

• 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.

Type	Measure	Description	Time frame	Safety issue
Primary	Volume of total tooth and resorbed area	The total volume and the resorption volume were measured with used 3D semi-automatic segmentation program (ITK-SNAP 2.4)	for three months from the beginning of the study
Primary	Measurement widest mesio-distal length, bucco-lingual length and corono-apical length of the resorbed lesion	Linear measurement were measured with used Planmeca ProMax 3D Classic (Planmeca Promax 3D; Planmeca Oy; Helsinki, Finland)	for three months from the beginning of the study
Primary	Linear measurements for thinnest dentin (buccal, distal, mesial and lingual/ palatinal) and resorbed area (mesio-distal length and bucco-lingual length) were made on axial sections	Linear measurement were measured with used Planmeca ProMax 3D Classic (Planmeca Promax 3D; Planmeca Oy; Helsinki, Finland)	for three months from the beginning of the study
