Cephalometric evaluation of a sample of Iraqi adults with normal occlusion using tetragon analysis


Background: This study aimed to determine the cephalometric values of tetragon analysis on a sample of Iraqi adultswith normal occlusion.Material and methods: Forty digital true lateral cephalometric radiographs belong to 20 males and 20 femaleshaving normal dental relation were analyzed using AutoCAD program 2009. Descriptive statistics and samplecomparison with Fastlicht norms were obtained.Results: The results showed that maxillary and mandibular incisors were more proclined and the maxillary/mandibularplanes angle was lower in Iraqi sample than Caucasian sample.Conclusion: It's recommended to use result from this study when using tetragon analysis for Iraqis to get moreaccurate result.
