Correlation Between Facial Measurements and Tooth Size and Pulp Volume

• Conditions: Cone-Beam Computed Tomography

• Registration Number: NCT04346641
• Lead Sponsor: Recep Tayyip Erdogan University Training and Research Hospital

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.

Primary Outcome Measures

Name	Time	Method
interalar distance	5 minute	Distance from ala of one side to other
Height of medium face	5 minute	Distance between glabella and subnasal
Commissural distance	5 minute	Distance from commissar of the lips
interpupillary distance	5 minute	Distance the center of the pupil of the right side to the center of the pupil of the left side
Mesiobuccal root length	5 minute	distance from enamel cement border of the tooth to the mesial root apex
Mesiodistal width	5 minute	Defined as the distance between two parallel planes, tangential to the most mesial and most distal points of the crown side
bizygomatic distance	5 minute	Distance from the most lateral parts of the arch of the zygomas
Height of inferior face	5 minute	Distance between subnasal and gnathion
Epicanthus distance	5 minute	Distance from inner palpebral fissures
Distobuccal root length	5 minute	distance from enamel cement border of the tooth to the distal root apex
Palatal root length	5 minute	distance from enamel cement border of the tooth to the palatal root apex
Pulp volume	2 hours
Buccal palatal width	5 minute	Defined as the maximum distance between two parallel planes, one tangential to the most palatal point of the crown side, and the other tangential to a point on the buccal crown side
Inter first molar distance	5 minute	The linear distance between right and left first molar teeth between the most convex palatal crown faces
