Diagnosis in orthodontics is rather different from diagnosis in medicine since it involves not merely localization of the disease or an anomaly but also a plan to normalize the existing malocclusion in the context of age. Comprehensive orthodontic diagnosis is established by use of certain clinical implements called diagnostic aids, which are further classified into essential and non– essential.  Radiology has long played a critical in orthodontic diagnosis and treatment planning.  Radiology has both direct and indirect effects on living system. The aim of the present study was to further burrow the impact of panoramic radiograph, lateral cephalogram and  additional hand wrist radiograph  in orthodontic diagnosis and treatment planning.
