Comparison of Angular and Linear Measurements of Soft Tissue Profile between Cephalogram and Photograph in Subjects with Class I and Class II Malocclusion
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2018, Vol 6, Issue 12
Abstract
Abstract: The reliability of hard and soft tissue landmarks on lateral cephalometric radiographs has been well documented. However; there is limited evidence about the reliability of facial soft tissue landmarks on photographs. Thus the aim of the present study was to compare angular and linear measurements of soft tissue profile between cephalogram and photograph in subjects with class I and class II malocclusion using Nemoceph software. Samples consist of digital lateral cephalogram and profile photograph of 30 subjects (15 Class I and 15 Class II) between age ranges of 18 to 35 years (mean22 ± 2.32). All records were taken in natural head position, centric occlusion and lips in relaxed position. 7 angular and 14 linear parameters were measured for soft tissue analysis on both lateral ceph and photograph using Nemoceph software. Student’s t-test was done for making adequate comparison. There was no statistically significant difference in the angular and linear parameters measured for soft tissue on cephalogram and photographs. Though cephalometric remains the method of choice for evaluation of dentoskeletal and soft tissue structure of patients, it can be summarized from the results of this study that photographs might be used as an alternative for large-scale epidemiologic studies, especially when there is a need for a low-cost, noninvasive method that can be used in diverse clinical and field settings.
