Orbital epitheses replace a missing eyeball and surrounding soft tissue. Perception of epithesis in public gaze and the attention areas on the face are of interest. This study aimed to examine the differences in perception of orbital epitheses by prosthodontists, dentistry students, and laypeople with an objective evaluation tool that utilized eye-tracking technology.
Twenty-four frontal facial images of 12 patients who had orbital epitheses were viewed by 81 observers (prosthodontists, dentistry students, laypeople) in random order for 5 seconds each. Gaze data were analyzed. Kruskal-Wallis H test with Bonferroni correction was used to compare parameters in groups and areas of interest.
First fixation duration at the mouth for symmetrical images were 0.30, 0.28, and 0.25 seconds for prosthodontists, students, and laypeople, respectively. Fixation duration at the mouth for the laypeople (0.27 second) was shorter than students (0.29 second) and prosthodontists (0.31 second) at symmetrical images. Time to the first fixation to epithesis, nose, and eye was significantly lower than the forehead and mouth for all groups. Fixation count at epithesis was 6.36 for prosthodontists, 5.64 for students, and 5.34 for laypeople.
Eyes were of most significant interest for all observer groups in symmetrical images. Individuals dealing with dentistry, especially prosthodontists, paid more attention to the mouth region along with the eyes in symmetrical images, considering fixation duration and fixation count. Attention directed to epithesis by all groups was verified with objective and measurable criteria. Prosthodontists' attention to epithesis and mouth was evident considering the four parameters measured.
眼眶赝复体用于替代缺失的眼球及周围软组织。公众注视下对眼眶赝复体的感知以及面部的关注区域备受关注。本研究旨在使用眼动追踪技术这一客观评估工具，检验口腔修复医生、牙科学生和普通民众对眼眶赝复体感知的差异。
81名观察者（口腔修复医生、牙科学生、普通民众）以随机顺序观看12例佩戴眼眶赝复体患者的24张正面面部图像，每张图像观看5秒。对注视数据进行分析。采用经Bonferroni校正的Kruskal-Wallis H检验比较各组及感兴趣区域的参数。
对于对称图像，口腔修复医生、学生和普通民众在嘴部的首次注视持续时间分别为0.30秒、0.28秒和0.25秒。在对称图像中，普通民众在嘴部的注视持续时间（0.27秒）短于学生（0.29秒）和口腔修复医生（0.31秒）。所有组看向赝复体、鼻子和眼睛的首次注视时间均显著低于额头和嘴部。口腔修复医生在赝复体处的注视次数为6.36次，学生为5.64次，普通民众为5.34次。
在对称图像中，眼睛是所有观察组最感兴趣的部位。考虑到注视持续时间和注视次数，从事牙科工作的人员，尤其是口腔修复医生，在对称图像中除了眼睛还会更关注嘴部区域。通过客观且可测量的标准证实了所有组对赝复体的关注。考虑到所测量的四个参数，口腔修复医生对赝复体和嘴部的关注很明显。
