Radiographic Assessment of Soft Tissue Thickness at the Anterior Area of Maxilla and Mandible in A Patient With Different Dental Malocclusions
Keywords:
CBCT, lateral cephalometric, gender, malocclusionAbstract
Background: Concerns about the accuracy and reliability of soft tissue thickness using CBCT and lateral cephalometric techniques.
Objective: The aim of the study is to estimate the accuracy and reliability of soft tissue thickness with CBCT and lateral cephalometric imaging for gender determination and to indicate the difference in soft tissue thickness in different dental malocclusions.
Material and methods: This study was conducted using 57 radiographic images (35 CBCT and 22 lateral cephalometric). Measurements for the thickness of soft tissue were done on the area of the anterior maxilla and mandible for both techniques.
Results: males have significantly thicker soft tissue than females in the area of the chin and distance from the labial surface of upper and lower central incisors to the surface of the lip, with p-values (0.0325,0.010,0.0094) respectively. An individual with Cl III shows a significant increase in soft tissue thickness in the area of distance from the labial surface of the upper central incisor to the surface of the upper lip, with a p-value 0.0018.
Conclusion: Males were characterized by thicker facial soft tissue compared with female patients in Class I. Individuals with Cl III show a reduction in the thickness of soft tissue in the area of the chin and an increase in the thickness in the area of the upper lip.
