Predictability of Yen Angle & Appraisal of Various Cephalometric Parameters in the Assessment of Sagittal Relationship between Maxilla and Mandible in Angle’s Class II Malocclusion
Journal Title: People's Journal of Scientific Research. - Year 2012, Vol 5, Issue 1
Abstract
The study was aimed to check the predictability and variability of Yen angle along with other sagittal discrepancy parameters and to discuss the correlation existing between them, so as to obtained a more reliable and least variable parameter for antero-posterior cephalometric analysis. The lateral cephalograms of 120 Class II malocclusion in Indian subjects were obtained and traced for seventeen different sagittal discrepancy parameters. The age of subjects ranged from 17-24 years. Study revealed that, Yen angle was highly reliable (CV= 1.81) and most homogenously distributed angular parameter to assess antero-posterior sagittal discrepancy. Other parameters like FABA, APDI/ PABA, SGn-AB and Beta angle also exhibit homogenous distribution and less variability in comparison to other parameters. As all the parameters used in the study share statistically significant correlation amongst themselves, instead of relying on one single parameter, others also should be checked and should be correlated with clinical findings.
