A sample of 47 untreated children with Class II Division I, deep overbite malocclusions who declined orthodontic treatment, showed that on an average of 11.5 years later, the absence of orthodontic correction will not usually lead to measurable occlusal deterioration in the young adult. This study did not discuss traumatic injuries in these untreated children. Posterior teeth are relatively unaffected. Dilacerated maxillary laterals and pointed teeth in general, showed greater root resorption. Blunted teeth had less resorption.
Adults have significantly more resorption than children in the mandibular anterior teeth only.
Increased tooth length and overjet were correlated with greater root resorption for the maxillary anterior teeth. Asian patients had less root resorption than whites who had less resorption than hispanics. Patients who underwent 4 first premolar extraction therapy had greater resorption than those patients who were treated nonextraction. There were not differences between the sexes. Patients over 80 pounds can be given 400mg of Ibuprofin one hour before their appointment and again six hours after their appointment as needed.
