Then, the obtained data were compared with T-tests. In the absence of significant differences and the validation of the software method, it is possible to measure facial anthropometric dimensions more easily and quickly in the target populations.</span></span><br> <span style="line-height:115%"><b><span new="" roman="" times="">Result</span></b><span new="" roman="" times=""> The study included 188 participants, with a mean age of 23.20 years. The results showed that out of the 10 dimensions measured, there was a statistically significant difference in five dimensions using the manual method and Scaniverse software (p-value < 0.05). In the other dimensions measured by the two methods, there was no difference in the mean (p-value > 0.05). The internal reliability and agreement of the measurements obtained using the two methods were assessed using the correlation coefficient, which yielded values ranging from 0.90 to 0.97, indicating high agreement and correlation.</span></span><br> <b><span style="line-height:115%"><span new="" roman="" times="">Conclusion</span></span></b><span style="line-height:115%"><span new="" roman="" times=""> While statistically significant differences were observed in five of the 10 facial dimensions, the Scaniverse software showed high agreement (ICC: 0.90-0.97) with manual measurements in all dimensions. These findings indicate that Scaniverse is a suitable alternative for measuring most facial anthropometric dimensions.</span></span></span></span> 3D scanning, Anthropometry, Facial dimensions, Manual measurement, Scaniverse software 219 227 http://hsm.umsu.ac.ir/browse.php?a_code=A-10-333-1&slc_lang=en&sid=1 Negar Semyari Negsim3@gmail.com 10031947532846004205 0009-0003-9128-7368 No Department of Occupational Health, School of Public Health, Urmia University of Medical Sciences, Urmia, Iran Teimour Allahyari allahyarit@yahoo.com 10031947532846004206 10031947532846004206 Yes Department of Occupational Health, School of Public Health, Urmia University of Medical Sciences, Urmia, Iran Vahid Alinejad vahidalinejad64@gmail.com 10031947532846004207 10031947532846004207 No Department of Statistics and Epidemiology, School of Public Health, Urmia University of Medical Sciences, Urmia, Iran
