EVALUATION OF ROOT RESORPTION IN RELATION TO 2 ORTHODONTIC TREATMENT REGIMES - A CLINICAL EXPERIMENTAL-STUDY

The aim of the investigation was to evaluate the effect of a treatment pause on teeth in which apical root resorption was discovered after a n initial treatment period of 6 months with fixed appliance. Forty pat ients with initial apical root resorption in 62 upper incisors were in cluded in the study. In 20 patients treatment continued according to t he original plan and in 20 patients active treatment was interrupted d uring a pause of 2-3 months. After the pause active treatment was resu med. Assessment of apical root resorption was performed on standardize d radiographs taken with individual film holders. The amount of root r esorption was significantly less in patients treated with a pause than in those treated without interruption.
