Abstract

Aim: To evaluate the validity of Yen, W and Beta angle and to compare it with other commonly used sagittal measurements in Eastern Indian population.
Materials and Methods: Sample size of 100 subjects (males -50, females 50, mean age - 25.5+-2 years) of indo aryan race were taken from the OPD of the College. The lateral cephalograms were traced for ANB, Wits appraisal, Beta angle, W angle and YEN angle. Lateral Cephalometric Head film was obtained with the patient positioned in Natural Head Position, seated Condyle, and with Passive Lips. The cephalograms were further traced by the same operator, this comprised the Cephalometric database for the study. The final results obtained were compared between Males and Females of the study to verify the acceptable standards of them.
Results: There was no statistically significant gender wise difference. Hence a common normative range applicable for both the genders can be proposed. The results show that all five-skeletal cephalometric sagittal analyses i.e. ANB angle Wits analysis, BETA angle, YEN angle and W angle are reliable and can used in different populations without any gross deviations in the findings.
Conclusion: Based on the present study, it can be concluded that no statistically significant differences in all parameters were found between the subjects of the Local Palamau population and also between the males and females. From the above statement ANB angle, Wits analysis, BETA angle, YEN angle and W angle can be used as they are reliable. All

Keywords: Cephalometric norms, W angle, YEN angle, Beta angle.
