Facialprofile determination using a novel face analyzer orthodontic mobile application.

Objectives: To find out the difference, the type of facial profile, and facial asymmetry between manual methods and mobile application, which is named the face analyzer orthodontic application. Facial profiles can be determined from the side of the face, categorized into three types: straight, convex, and concave profiles. Facial asymmetry refers to the imbalance between facial components concerning size, shape, and opposing positions of planes, lines, or points.

Materials and methods: The research design was a cross-sectional study design using extra oral patient photographs who were treated in Orthodontic Department of Nala Husada Dental Hospital, Surabaya. The technique used was simple random sampling. The number of samples obtained based on inclusion and exclusion criteria was 37 patients, ranged 9-15 years old. The facial profile and asymmetry were determined from extra oral photos before objectively analyzed and processed in face analyzer application by comparing with the manual technique. Wilcoxon test, used to determine the significance value of facial profiles and the facial asymmetry, was analyzed by McNemar's test.

Results: Testing on two variables with two different treatment groups obtained P > 0.05. The Wilcoxon test result (P = 0.157) indicates there is no significant difference, and the McNemar test result (P = 0.375) indicates there was no significant difference in the two groups.

Conclusions: The results of determining the facial profile and facial asymmetry showed no difference between manual and face analyzer orthodontic mobile applications.
