A Digital Method for Measurement of Palatal Asymmetry in Twins

Not Applicable

Completed

• Conditions: Identity, Body; Palate; Deformity
• Interventions: Device: Intraoral scanning and data acquisition

• Registration Number: NCT05349942
• Lead Sponsor: Semmelweis University

Brief Summary

The aim of the study is to evaluate the digital palatal model as a possible tool of human identification.

Detailed Description

In this research, the investigators investigate the individual characteristics of the human upper and lower dentition and palate. The investigators use digital dentistry, record the data using an intraoral scanner, and store the extracted open source file format on a secure cloud-based server. Data validation is repeated annually. By comparing the initial and control digital samples, the investigators draw conclusions about the usability of the extracted information. The aim of the study is to develop a method and data storage protocol that will allow the patient data to be used years or decades later to replace or restore lost information.

Primary Outcome Measures

Name	Time	Method
Deviation value between 3 human palatal scans	30 second between data acquisition	The deviation value will be measured in mm between three human palatal scans of the same individual by GOM Inspection software.
Deviation value among scans	30 second between data acquisition	The deviation value will be measured in mm between 9 comparisons of twin siblings by GOM Inspection software.
Deviation value between 2 scans	30 second between data acquisition	The deviation value will be measured in mm between 2 human palatal scans of the same individual by GOM Inspection software.
Deviation value between original scans and mirrored scans of the individual	30 second between data acquisition	The deviation value will be measured in mm between the original human palatal scans and mirrored human palatal scans of the same individual by GOM Inspection software.
Deviation value between original human palatal scans and mirrored human palatal scans of the twins	30 second between data acquisition	The deviation value will be measured in mm between the original human palatal scans and mirrored human palatal scans of twin siblings by GOM Inspection software.
