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,

Calcium hydroxide in the treatment of external root resorption

The Journal of the American Dental Association, 1989
A case is presented in which calcium hydroxide was used in endodontic treatment of external root resorption in a tooth with a necrotic pulp, during active orthodontic movement. A calcified deposit formed, filling a defect, and the tooth was subsequently obturated with gutta-percha. Thus, both types of therapy--endodontic and orthodontic--were performed

External root resorption caused by luxation of rat molars

European Journal of Oral Sciences, 1973
abstract – Following elevator luxation of the mandibular first right molar in 36 10‐weekold male Wistar SPF rats, three different kinds of external root resorption were observed. Surface resorption, found mainly on the sides where pressure was exerted, was recorded histometrically from 3 to 21 d after the trauma.
