Figure 7: An overview of the ectomesenchymal influence on craniofacial and dental morphology. Upper left: Profile radiograph of a patient with skeletal open bite. The four dental radiograph images to the right illustrating cervical root resorption, plump root morphology, and short incisor root, which are all conditions predisposing root resorption during orthodontic treatment. Lower: Three radiographs illustrating abnormal root morphology and cervical root resorption in Paget's disease^[8]
