Root resorption associated with pressure or mechanical stimulation may be seen in individuals undergoing orthodontic treatment and can be caused by the application of excessive force. It occurs in the apical region and the resorbed area undergoes repair and remodeling when the cause is removed. It is possible that excess force could cause an aseptic death of the periodontal ligament, followed by inflammation. Pressure may also be a factor in root resorption associated with tumors or, occasionally, cysts involving the roots of teeth. Continue reading
