ABSTRACT
Background and objective: In recent years, researchers have been looking for new relationships between respiratory function and the chance of developing malocclusions, and early diagnosis and treatment algorithms have been created. In this study, an observation was done to evaluate how hard and soft tissues, as well as upper airway morphology, differed by gender in patients with normal sagittal occlusion and Angle Class II malocclusion.
Materials and methodology: 119 pre-orthodontic patients with normal or increased ANB angle were randomly selected for the study after clinical and radiological data were evaluated. The cephalometric radiographs were traced manually and by a machine device for obtaining pharyngeal airways and soft tissue profile
Results: The cephalometric showed that patients with class Il anomalies had a statically significantly increasing in ANB angle, the upper pharyngeal width was statically significantly wider, and the facial convexity angle was bigger in class I than class II patients. According to gender, only the upper lip thickness at point A for males were very highly significant than females in class I patients.
Conclusion: It was noticed that the upper lip thickness was greater in males than in females for both class I and class II patients, the upper pharyeang| width was wider in class I than class II patients, Angle Class II patients they had more constricted airways.
