Brief Summary:
Retrospective Data Analysis will be performed after the CBCT images are pooled from the computer database
Exposure parameters of the scans will vary depending on patients sizes according to the manufacturers recommendations
Images showing lower anterior mandibular teeth with 02 -04 voxel sizes will be reviewed
The topography and the quantity of the mandibular symphysis area will be assessed through the different planes sagittal coronal and axial cuts as well as assessing the prevalence of MIC and its distance from inferior border of the mandible if detected Correlation of results according to gender and age 3 age sub-groups per gender18-35 36- 55 56-75
CBCT images will be interpreted by oral and maxillofacial radiologist blinded from demographic data of the patients
radiologist Principle investigator will evaluate the images for assessing the topography and quantity of bone in symphysial area through measuring dimensions of mandibular symphysis Then will re-evaluate twice with a time lag of two weeks between the two reading sessions The assistant supervisor will evaluate percentage of the scans Any disagreement will be solved by consensus between the two observers
The measurements will be carried out by the principle observer PY and will be repeated 2 weeks later for intra-observer reliability assessment
Mandibular scans will be collected from planmeca machine with 02-04 voxel size to be viewed on Romexis software to do the measurements of mandibular symphysis Vertical height will be measured from the apices of anterior teeth to inferior border of the mandible from the sagittal and coronal cuts with the orientation lines parallel to the buccal cortical plate Also the sagittal cuts will be used to determine the depth of the labial bone from the apices of anterior teeth the labial cortical plate with the orientation lines parallel to the buccal cortical plate Safi Yaser et al2021 Whilst horizontal dimension width will be measured along the outer surface of the labial cortical bone which is determined from the inter-foraminal distance 3D slicer software will be used for this curved measurement on the axial plane since Romexis software can only do the linear and angular measurements Lee Kim et al 2014
Also the sagittal reformatted cuts will be used for the determination of the topography of bone in symphysial area either class I II or III Jussara Constantino et al 2018 Radiographs showing the different topographic types Radiograph A Type I B Type II and C Type III
Through scrolling in sagittal coronal cuts and the reformatted panoramic view the prevalence of mandibular incisive nerve will be detected Borghesi Andrea et al 2022
After collecting the whole data statistically will be correlated to the age and gender
