Background/aim: This study aimed to assess the components of Björk–Jarabak's cephalometric analysis and the facial profile among Yemeni adults.
Methods: This retrospective research comprised 72 (36 males and 36 females) lateral cephalometric radiographs (LCRs) of adult Yemeni samples. Based on their facial profiles, each group was classified into three subgroups: straight, convex, and concave, with 12 participants in each subgroup. The LCRs were analyzed using the five Björk–Jarabak cephalometric analysis parameters via the WebCeph web artificial cephalometric analysis software for genders and subgroups. The LCRs were analyzed, assessed, and measured in terms of three angles (saddle, gonial, and articular) and two lines, namely the anterior and posterior facial heights. Statistical significance was set at p < 0.05 for all tests.
Results: The participants had an overall mean age of 20.32 ± 3.55 years. The articular angle (AA) was significantly different between groups and genders (p = 0.000). Subjects in the convex group showed significantly higher values of AA compared with the concave group (150.47 ± 5.34 vs 143.75 ± 4.66). No significant differences were recorded for the saddle angle (SA), gonial angle (GA), and facial heights between groups.
Conclusion: AA exhibited a considerably greater influence on the convex facial profile, and its adjustment should be evaluated during treatment planning. Higher anterior and posterior facial heights were observed among males.
Clinical significance: The findings can enhance orthodontic diagnosis and treatment planning, particularly for individuals from similar ethnic backgrounds, by offering region-specific normative data and an understanding of facial esthetics.
