Introduction: Craniofacial anthropometry and anthropometric ratios are used in different sciences such as dentistry, medicine, oral and maxillofacial surgery, growth studies, plastic surgery, bioengineering and production of personal protective equipment. The purpose of this study is to introduce Digimizer software to measure facial dimensions and compare manual dimensional measurement and photoanthropometry with this software.
Methods: In This descriptive-analytical study 12 female students of Shiraz University of Medical Sciences participated. Measurement of face dimensions of samples was done manually and by photographic methods and data analysis was performed with SPSS software version 19 and descriptive-analytical tests.
Results: From the ten dimensions of the measured dimensions, a significant difference was observed in the three dimensions of the Subnasal-Nasal Root Length (SNRL), Menton-Nasal Root Length (MNRL) (Face Length) and Bitragion-Menton Arc (TRMA) dimensions,(P <0.05 ). No significant differences were observed in other dimensions. The ICC (Intra Class Correlation) coefficient for both methods was obtained in the range of 0.56-0.94.
Conclusion: This study showed that the use of Digimizer software can replace the use of manual method in measuring the dimensions of the face and in the preparation of anthropometric database of the face in less time is preferable to the manual method.
