“…It can also be seen further that Yen angle and W angle show least correlation with Wits appraisal with values of r 2 = 0.384 and r 2 = 0.275 respectively, although both ANB angle and Wits appraisal show a good correlation with each other with r 2 = 0.605. This is in contrast to the findings of Mittal et al, 12 where they found a strong correlation of Yen and W angle with Wits appraisal. A good correlation of Yen and W angle with Beta angle was also found in this study with r 2 = 0.462 and r 2 = 0.570 respectively.…”

“…Further, it can be seen in Tables 3 and 4 and Graph 1 that Yen angle and W angle show a good correlation with each other with r = 0.684 and r 2 = 0.467. This finding also correlates with that of Mittal et al 12 (r = 0.735) and Trivedi et al 14 (r = 0.894), who also found a good correlation between Yen angle and W angle. Further, it can also be seen in Table 3 that Yen angle and W angle show best correlation with ANB angle with r 2 = 0.753 and r 2 = 0.571 respectively (Graphs 2 and 3), than either with Wits appraisal or Beta angle.…”

“…In Table 2, the correlation among all the five parameters is calculated, wherein it can be seen that they all show a significant correlation ( < 0.001) with each other, suggesting that all the five parameters can be successfully used in assessing the sagittal jaw discrepancy. This finding correlates with that of Mittal et al, 12 Doshi et al, 13 Trivedi et al, 14 and Alam et al 15 ANB angle and Wits appraisal show a positive correlation with each other, but negative correlation with Beta angle, Yen angle, and W angle. This is due to the difference in the method of assessment used by these indicators.…”

“…The reason being that ANB angle, Yen angle, and W angle use a common reference "point S" for their measurements. The findings of Mittal et al 12 also show a strong correlation of Yen and W angle with ANB angle, whereas the findings of Trivedi et al 14 show a strong correlation only of W angle with ANB angle, but not of Yen angle.…”

Introduction Sagittal jaw relationship is one of the basic criteria assessed for orthodontic diagnosis. ANB angle, Wits appraisal, and Beta angle are the most commonly used measures. Yen angle and W angle have been recently introduced. It was necessary to assess their predictability by comparing them with routinely used sagittal jaw indicators. Aim To assess Yen angle and W angle and compare them with ANB angle, Wits appraisal, and Beta angle in predicting sagittal jaw dysplasia. Materials and methods A total of 40 lateral cephalograms of class I malocclusion subjects were selected and traced as per the inclusion criteria. ANB angle, Wits appraisal, Beta angle, Yen angle, and W angle were measured and compared with each other. Statistical analyses used were independent t-test, Pearson's correlation coefficient, sensitivity, specificity, and accuracy. Results ANB angle, Wits appraisal, Beta angle, Yen angle, and W angle all show a significant correlation with each other. Yen angle and W angle show best correlation with ANB angle showing 100% sensitivity. The values of specificity and accuracy of Yen angle with ANB angle are 73.7 and 81.48% respectively, and that of W angle with ANB angle are 44.4 and 67.74% respectively. Conclusion Yen angle and W angle show a good correlation with each other and with other three measures. Both the angles show highest correlation with ANB angle and the least correlation with Wits appraisal. Yen angle shows stronger correlation with ANB angle than W angle. Yen angle and W angle can be used to assess sagittal jaw dysplasia in addition to the established angles. How to cite this article Kapadia RM, Diyora SD, Shah RB, Modi BN.

: The measurements for assessing the antero-posterior discrepancy between the apical bases are many with their individual benefits and shortcomings. So, it is very important to categorize the reliability of the major diagnostic criteria for successful planning of treatment and to fore see the outcome. The present study assesses the predictability of Wits appraisal, ANB, Beta, Yen, W, µ and Pi angles as an indicators of anteroposterior dysplasia. A total of 120 lateral cephalograms of skeletal Class I, II and III patients were selected based on Down’s facial angle and then tracing was carried out manually to measure Wits appraisal, ANB, Beta, Yen, W, µ and Pi angles. Analysis of variance and correlation coefficient analysis were done to assess the significance of association between these variables. Yen angle is highly predictable and a homogenously distributed angular parameter used to assess sagittal discrepancy. The most desirable differentiation results among the three skeletal relationship were represented by Beta angle followed by Yen angle. Statistically significant correlation among the seven parameters for skeletal Class I relationship were shown by Yen and W angle, for skeletal Class II relationship by Beta angle and µ angle and for skeletal Class III relationship by Beta angle and W angle. No statistically significant correlation existed between Yen Angle and Beta Angle in all the three groups. Yen angle was found to have the most homogenous and predictable parameter. A statistically significant correlation for skeletal Class I relationship were observed between Yen and W angle, for skeletal Class II relationship between Beta and µ angle and for skeletal Class III relationship between Beta angle and W angle and they can be used interchangeably in assessing skeletal jaw relationship.

Background/Objectives An accurate evaluation of skeletal sagittal jaw relationship has an important role in orthodontic diagnosis and treatment planning. This study was done to establish cephalometric norms of all types of malocclusion using ANB, Wits appraisal and Beta angle, and evaluate the significance of W angle in comparison to these parameters. Subjects and Methods Ninety pre-treatment lateral cephalograms of male and female patients aged 18-28 years from Sulaimani City that met the sample criteria were traced digitally by the Easy Dent 4 software program. The sample was divided into three groups of skeletal malocclusion, class I, II, and III, based on ANB angle, Beta angle, and Wits appraisal, each group consisting of 30 patients. For each subject the following cephalometric parameters were measured: ANB angle, Beta angle, Wits apprasial, and W angle.Statistical analysis The Statistical Package for Social Sciences was used for analyzing data. ANOVA test was used to compare means of the three study groups. The post-hoc test was used to compare each two groups, Pearson correlation coefficient (r) was used to assess the strength of correlation between two numerical variables, and coefficient of variability was used to measure the extent of variability of each variable in relation to the population. The p value of ≤ 0.05 was considered statistically significant. ResultsSignificant differences were found in the ANB angle, Beta angle, Wits appraisal and W-angle in all 90 patients. The coefficient of variability showed that Wits appraisal was the most variable parameter and W angle was the least variable parameter. Conclusions ANB angle, Beta angle, Wits appraisal and W-angle are significant parameters to assess the sagittal jaw relationship. The use of W angle, along with other parameters, can provide more accurate assessment of the sagittal skeletal jaw relationship as it has the least coefficient of variance; it should therefore enable better diagnosis and treatment planning for patients.
