Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
skeletal class II subjects
patients with wits appraisal more than 3 mm measured on a cephalometric x ray obtained during diagnosis
blood type test
a blood sample will be withdrawn from the subjects tested by anti A anti B and anti D antigens to detect the individuals blood group and RH. then statistical analysis to detect presence of a relationship between skeletal types of malocclusion and ABO blood groups
skeletal class III subjects
patients with wits appraisal less than -3 mm measured on a cephalometric x ray obtained during diagnosis
blood type test
a blood sample will be withdrawn from the subjects tested by anti A anti B and anti D antigens to detect the individuals blood group and RH. then statistical analysis to detect presence of a relationship between skeletal types of malocclusion and ABO blood groups
skeletal class I patients
patients with Wits appraisal between -3 and +3 that is measured from a cephalometric x ray obtained during diagnosis of arch length discrepancy. this group will serve as control and obtained after recruitment of the other 2 groups in 1 to 1 fashion
blood type test
a blood sample will be withdrawn from the subjects tested by anti A anti B and anti D antigens to detect the individuals blood group and RH. then statistical analysis to detect presence of a relationship between skeletal types of malocclusion and ABO blood groups
