ABSTRACT:Objective: To determine and compare the relationship between pharyngeal volume in subjects with class II div I and div II malocclusions. And To determine the relationship between different growth patterns and pharyngeal volume.
Materials and Method: This study was conducted among 60 patients in the age group of 18 to 45 years of North Indian origin with class II malocclusions requiring CBCT, reporting to the department of Orthodontics and Dentofacial Orthopaedics at RUHS College of Dental Sciences, Jaipur out of which 30 were class II div I (15 vertical and 15 horizontal growth pattern) and 30 were class II div II (15 vertical and 15 horizontal growth pattern Cone beam computed tomography scans were taken using Carestream CS9300 imaging system (CS 3D Imaging v3.5.7; Carestream Health Inc New York, USA) using FOV of 17x11 cm. Two characteristics in each cbct were measured using the dr Able ( 3d doctor) software : pharyngeal volume in (cm) cube in relation to type of class II malocclusion and pharyngeal volume in (cm) cube in relation to type of growth pattern in class II malocclusion.
Results: No significant difference in pharyngeal volume found between skeletal class II div I and div II group Significantly Reduced pharyngeal volume found in vertical growth pattern group.
Conclusion: Pharyngeal volume in class II div II group was less as compared to class II div I group but difference was statistically insignificant Vertical growth pattern patients have lower pharyngeal volume as compared to horizontal growth pattern in both sub divisions of class II malocclusion confirming an association between pharyngeal airway space and a vertical skeletal pattern.
