Abstract
ABSTRACTBackground: This study aimed to establish the mean value of Anteroposterior Dysplasia Indicator (APDI), asmeasurements of the sagittal discrepancy and Overbite Depth Indicator (ODI), as measurement of verticaldiscrepancy, in a sample of Iraqi adults with different skeletal classes.Materials and Methods: Ninety dental students, 30 subjects have class I (15 males and 15 females), 30 subjects haveclass II (15 males and 15 females) and 30 subjects have class III (15 males and 15 females) were chosen for this study.Each student was subjected to clinical examination and digital true lateral cephalometric X-ray. The radiographswere analyzed using AutoCAD 2007. Descriptive statistics obtained for the variables for both genders, independentsamples t-test was performed to evaluate the gender difference, and ANOVA then LSD tests were applied tocompare the measurement among the skeletal classes.Results and Conclusions: The mean value of APDI and ODI were established for class I, class II and class III, the APDIand ODI values showed high statistically significant differences among the different skeletal classes for both genders.The mean value of APDI was greater for class III group, and the mean value of the ODI was greater for class II groupand it was smaller in class III group.Keyword: APDI, ODI.
