Abstract
Background:One of the most important factors in the planning of orthodontic treatment and the assessment of treatment changes is to evaluate the soft tissue. For this purpose, quantitative assessments of soft tissue have been performed using lateral cephalometric radiographs classically, and several cephalometric analyses have been developed and proposed. It is not possible to evaluate the soft tissues from the frontal view using cephalometric radiographs. In addition to cephalometric radiographs, soft tissue evaluation has been carried out by means of different methods such as anthropometry, two- or three-dimensional photogrammetry, and three-dimensional imaging techniques. Among these methods, two-dimensional photogrammetry has the advantage of being a basic, non-invasive, cost-effective, and quick method that requires minimal time and equipment in the assessment of soft tissue. Aim:This study aims to assess the reliability of photogrammetry in assessing the frontal facial proportions in comparison to anthropology. Materials and Methods:Frontal photographs of 18 male and 18 female healthy young adults were taken in natural head position and frontal facial proportions were assessed in software on the photograph, and real-life measurements were taken on the subject using Vernier calipers. Two indices were assessed upper face-to-face height index and lower face-to-face height index. An independent sample t-test was used to assess the difference among the two methods used. Results:No statistically significant difference between manual and photogrammetric measurements was seen. Conclusions:Photogrammetry can be effectively used as an alternative to anthropometry when similar technique is used for acquiring the photograph of the subjects.
