About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

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.

Treatment and study plan

Primary outcomes

  1. Volume of total tooth and resorbed area

    Time frame: 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)

  2. Measurement widest mesio-distal length, bucco-lingual length and corono-apical length of the resorbed lesion

    Time frame: 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)

  3. 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

    Time frame: 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)

  4. The corono-apical length was measured on sagittal sections where the tooth axis was perpendicular to the ground plane.

    Time frame: 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)

  5. the axial section of the tooth was divided into eight parts and regional settlement classification was performed

    Time frame: 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)
