Design Details

  • Primary Purpose: Diagnostic
  • Allocation: Non-Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Manual segmentation technique of CBCT images of the condyles.
Using the manual edition built in tool, first a brush of small size will be used to demarcate the outline of the condyle in the sagittal cuts. Then shading the demarcated condylar area with a brush of larger size in each slice. The outline of the condyle will be refined on all cuts. The software built in tool 'create surface' will be used to create the segmented 3D volume
Radiation: CBCT radiation
CBCT scanning
Experimental: Semiautomatic segmentation technique of CBCT images of the condyles.
Using the water shed built in tool, first a brush of small size will be used to demarcate the outline of the condyle by the 'background' option in all planes. Then using the 'foreground' option, a brush of larger size will be used to shade the condylar area. The software built in tool 'expand water shed' will be used to include the whole condyle. At last, 'create surface' option will be used to create the segmented 3D volume.
Radiation: CBCT radiation
CBCT scanning
No Intervention: Actual physical measurements of the condyles on the dry mandibles

For linear measurements, actual physical measurements will be done on the dry mandibular condyles, using digital caliper, as mentioned before.

For volumetric measurements, water displacement technique will be used. The mandibular condyle will be immersed in a graduated beaker containing water till the level of the glued gutta percha. The volume of the displaced water will be measured and will represent the actual volume of the condyle

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Linear assessment of the condyles
Time Frame: one month
Linear measurements will be calculated in millimeters by Built-in measuring tool (ruler) in the software + digital caliper on the dry mandibles
one month

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Volumetric assessment of the condyles
Time Frame: one month
For volumetric measurements, the volume of the segmented condyle, either by manual or semiautomatic segmentation technique, will be automatically calculated by the software. Volumetric measurements will be calculated in cubic millimeters.
one month
