Official Title: Study of the Relationship Between Blood Groups,RH and Skeletal Malocclusion in a Group of Egyptian Population: a Cross Sectional Study

Brief Summary: the study is searching if there is a relationship between the blood groups and RH and the skeletal malocclusion using the skeletal class I as a control group

Detailed Summary: The study will be conducted on the patients seeking medical care in the orthodontic department Cairo University, for six months all patients with class II and class III malocclusion will be recruited based on Wits appraisal measured from the cephalometric X-ray taken routinely during orthodontic examination. Then a group of class I arch length discrepancy patients will be used as control. A blood sample will be withdrawn and taken to the Cairo university laboratory to analyze the blood group and RH .a statistical analysis will be performed to detect a relationship between skeletal malocclusion and the blood groups as compared to the control
Sponsor: Cairo University

Current Primary Outcome: relationship between blood group and skeletal malocclusion [ Time Frame: the recruitment will be for six months ]

If skeletal malocclusion subjects were found to have a high percentage of a certain blood type or RH when compared to the control group it will be reported that there is a relationship between blood group and skeletal malocclusion. If percentages of blood groups are approximately the same in the malocclusion subjects and the control then the investigator will report that there is no relationship between blood groups and skeletal malocclusion


Original Primary Outcome: relationship between blood group and skeletal malocclusion [ Time Frame: the recruitment will be for six months ]

if skeletal class II patients were found to have a high percentage of a certain blood group than the same blood type in the control group we will say there is a realtionship between blood group and skeletal malocclusion.if percentages are approximately the same then no relationship between blood groups and skeletal malocclusion all blood groups are of the same or clode percentage in the malocclusion
