| Sumario: | Root resorption detectable histologically can be a preliminary step toward external apical root resorption that is permanent and detectable radiographically. When root resorption exceeds the reparative capacity of cementum, root resorption ensues. External apical root resorption is a reduction of root structure involving the apices. This occurrence has been reported with and without orthodontic treatment and can be diagnosed by orthodontists during routine diagnostic, progress and post-treatment radiographs. It has been reported that 5 mm or more of apical root resorption may occur in 5% of orthodontic patients. There is an association of root resorption in those who have not received orthodontic treatment with missing teeth, increased periodontal probing depths, and reduced crestal bone heights. Individuals with bruxism, chronic nail biting, and concomitant tongue thrust may also show an increased extent of EARR before orthodontic treatment. Dental trauma, especially with re-implantation of an avulsed tooth, is also associated with root resorption. Since mechanical forces and other environmental factors do not adequately explain the variation seen among individual expressions of root resorption, interest has increased on genetic factors influencing the susceptibility to resorption. The reaction to orthodontic force, can differ depending on the individual’s genetic background. |
