Mean while; to find the facial height variations among the Class I, II and III dentoskeletal groups. Materialsand Methods: The sample comprised of 32 lateral cephalometric radiographs (16 for each sex) for each of the Class I, II and III dentoskeletal relationships. The age of the sample subjects was 15–20years. The lateral cephalometric radiographs were traced. The total, upper and lower anterior facial heights and the total, upper and lower posterior facial heights were measured. Results: No significantdifferences among the both sexes and total sample for the dentoskeletal groups were demonstrated. All the facial heights appeared significantly greater in Class II group than Class I group except upperanterior, upper posterior and lower posterior facial heights and was significantly higher than Class III group in upper anterior, lower anterior and upper posterior facial height. Class III group displayedsignificantly lower value in total facial height than Class I group and significantly larger value in lower posterior facial height than of Class I group and Class II group. Conclusion: The facial heights are notaffected by the sex variation, but there are certain variations in facial heights among the dentoskeletal groups.
