Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
in the panoramic views the long axes of canines and second premolar will be traced digitally using Digital softwares (microDicom vierwer Simeo Antonov Stoykov 0.7.7) \& (IC Measure 2.0.0.161).
The objective of this study is to assess the root parallelism between maxillary canines and second premolars in adolescents versus adults group of patients requiring maxillary first premolar extraction during the orthodontic treatment.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
adolescent group
Panoramic radiographs of finished orthodontic cases will be collected after fulfilling the inclusion and exclusion criteria. Then the collected data will be divided into two groups according to age either adolescent (12-18 years old) or adult group (after 18 years old).
measurements will be done on the radiograph using digital software.
first premolar extraction and complete canine retraction.
measurements on panoramic radiograph will be done after first premolar extraction and complete canine retraction.
