Volumetric Analysis of Resorption Types on CBCT

Completed

• Conditions: Endodontic Disease; Tooth Resorption

• Registration Number: NCT04617301
• Lead Sponsor: Recep Tayyip Erdogan University Training and Research Hospital

Brief 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.

Detailed 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.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 43

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.

Primary Outcome Measures

Name	Time	Method
The corono-apical length was measured on sagittal sections where the tooth axis was perpendicular to the ground plane.	for three months from the beginning of the study	Linear measurement were measured with used Planmeca ProMax 3D Classic (Planmeca Promax 3D; Planmeca Oy; Helsinki, Finland)
Volume of total tooth and resorbed area	for three months from the beginning of the study	The total volume and the resorption volume were measured with used 3D semi-automatic segmentation program (ITK-SNAP 2.4)
Measurement widest mesio-distal length, bucco-lingual length and corono-apical length of the resorbed lesion	for three months from the beginning of the study	Linear measurement were measured with used Planmeca ProMax 3D Classic (Planmeca Promax 3D; Planmeca Oy; Helsinki, Finland)
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	for three months from the beginning of the study	Linear measurement were measured with used Planmeca ProMax 3D Classic (Planmeca Promax 3D; Planmeca Oy; Helsinki, Finland)
the axial section of the tooth was divided into eight parts and regional settlement classification was performed	for three months from the beginning of the study	Segmentation were made with used Planmeca ProMax 3D Classic (Planmeca Promax 3D; Planmeca Oy; Helsinki, Finland)
