Correlation Between Facial Measurements and Tooth Size and Pulp Volume

Study Overview
=================
Brief Summary
-----------------
The aim of this study was to investigate the correlation between the measurements of the specific points of the face (lower face height, midface height, the distance between zygomatic, pupillary distance,interalar distance, epicanthus distance, the distance between commissar) and the dimensions of the maxillary sixth molar tooth (mesiodistal distance, buccal palatal distance, root length, pulp volume).

Detailed Description
-----------------
Radiographic images of patients who have been indicated for cone-beam computed tomography for the upper jaw for various reasons (such as impacted teeth, sinusitis, skeletal anomalies) will be reviewed retrospectively. Facial measurements (lower face height, midface height, inter-zygomatic distance, inter-pupillary distance, interalar distance, epicanthus distance, the distance between commissures) of the patients who received cone beam computed tomography will be measured in the clinic. Mesiodistal distance, buccal palatal distance, root length, pulp volume of maxillary sixth tooth will be measured using cone beam computed tomography. The data obtained will be compared.
