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).

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.

Inclusion Criteria:

• Upper dental arches which have maxillary first molars
• At least one tooth which has no deep caries, filling or crown restoration must be
• No resorption or pathology in the root of the tooth which disrupt integrity must be
• Healthy subjects

Exclusion Criteria:

• Deep caries, filling or crown restoration
• Resorption or pathology in the root of the tooth

Above 15 years old, healthy subjects
