| ABSTRACTBackground: This study was designed to investigate the relationship between the ramus notch depth and some of thecraniofacial measurements in Iraqi adults with skeletal Cl I, Cl II and Cl III; and to find out if there were any differences inthe ramus notch between the skeletal classes.Materials and method: The sample consisted of 174 pretreatment digital lateral cephalometric radiographs of Iraqis agedbetween 18-25 years old (85 females and 89 males). Seven linear and six angular measurements were analyzed usingAutoCAD (2007) software computer program. Descriptive statistics and gender differences were done for themeasurements. ANOVA test compared the ramus notch depth between the skeletal classes, while Pearson correlationcoefficient test was used to identify the correlations between ramus notch depth and other measurements.Results: From linear measurements only the ramus notch depth was not significantly different between genders. Nonsignificantdifferences of the ramus notch depth between the skeletal classes were revealed by ANOVA test. Significantpositive correlations of the ramus notch depth were found with the ramus length, total anterior facial height, loweranterior facial height, posterior facial height and the saddle angle for the total sample.Conclusions: The ramus notch depth is not affected by gender or sagittal jaws relationship. The increased ramus notchdepth may be one of the signs of the long face syndrome without openbite. Deep ramus notch is associated with themandibular retrusion or backward position of the ramus.Key words: Ramus notch, craniofacial measurements. skeletal patterns.
