Reliability of E Analysis in Assessing Skeletal Class II Malocclusion in Kerala Population
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2018, Vol 3, Issue 2
Abstract
Aim: The objective of this study was to assess the reliability of the E analysis in subjects with skeletal class II malocclusion based on their ANB and WITS appraisal values. Materials and Methods: This retrospective study was conducted in the Department of Orthodontics and Dentofacial Orthopedics, A.B Shetty Memorial Institute of Dental Sciences, comprising of lateral cephalograms and case history records of 30 skeletal Class II patients (15 males and 15 females). The lateral cephalograms were traced and the ANB, Wits Appraisal and E analysis. The values were correlated using pearsons co relation test. Gender differences for the E analysis values were calculated using the unpaired t test. Results: There was no significant difference in the mean values of E analysis variables between males and females. There was a positive correlation in all the parameters. M-HPp – D-HPp correlates statistically significant with ANB angle and Wits appraisal with a Pearson’s correlation coefficient of 0.602 and 0.405. Conclusion: Any M-HPp – D- HPp value of 2mm or more can be considered as a skeletal class II malocclusion in the kerala population. The E analysis does serve as a very stable and useful cephalometric parameter which can help us in better diagnosis and treatment planning.
