Orthodontics and External Apical Root Resorption

Seminars in Orthodontics, 2007
External apical root resorption (EARR) is a common complication of orthodontic treatment. Many factors have been investigated to explain differences seen among individuals in their susceptibility to EARR. Our central hypothesis is that in addition to the environmental component (increased stress and strain on the teeth, surrounding periodontal ligament,

Effect of Allergen Sensitization on External Root Resorption

Journal of Dental Research, 2013
In orthodontic tooth movement (OTM), we should be concerned about external root resorption (ERR) as an undesirable iatrogenic problem, but its mechanisms are not fully understood. Since our previous epidemiologic studies found that patients with allergic diseases showed higher rates of ERR during orthodontic treatment, we explored the possible effect ...

Possible etiologic factors in external root resorption

American Journal of Orthodontics, 1975
The causes of external root resorption have remained an enigma to the dental profession since oral roentgenography was introduced. Numerous investigators have implicated various etiologic agents with root resorption, and, with the exception of those studies evaluating root loss following orthodontic treatment,8s 9, 2x, 32 they are generally ...
