Apical root resorption six and 12 months after initiation of fixed orthodontic appliance therapy.
The low explained variance of identified risk factors for apical root resorption in orthodontic patients suggests effects of parameters related to individual predisposition. Our purpose was to explore this hypothesis. We evaluated standardized periapical radiographs of the maxillary incisors made before treatment (T1) as well as at about six and 12 months after bracket placement (T2 and T3) of ...
متن کاملExternal apical root resorption following orthodontic treatment.
This study investigated the association of appliance type and tooth extraction with the incidence of external apical root resorption (EARR) of posterior teeth following orthodontic treatment. Pre- and posttreatment orthopantomograms were compared for 97 patients and a 4-grade ordinal scale used to measure EARR. The incidence of EARR was positively associated with tooth position (P < .001), appl...
متن کاملAnalysis of correlation between initial alveolar bone density and apical root resorption after 12 months of orthodontic treatment without extraction
OBJECTIVE The aim of the present study was to investigate the correlation between initial alveolar bone density of upper central incisors (ABD-UI) and external apical root resorption (EARR) after 12 months of orthodontic movement in cases without extraction. METHODS A total of 47 orthodontic patients 11 years old or older were submitted to periapical radiography of upper incisors prior to tre...
متن کاملComparing The Rate of External Apical Root Resorption During Orthodontic Treatment in Posterior Permanent Endodontically Treated and Vital Teeth
Background and Aim : One of the concerns about orthodontic treatment is the external apical root resorption(EARR).Therefore, the aim of this study was to compare the rate of EARR in posterior permanent endodontically treated and vital teeth after orthodontic treatment. Materials and methods: This observational and retrospective study was performed on 112 roots in 28 patients in the age range o...
متن کاملApical root resorption after orthodontic treatment -- a retrospective study.
The purpose of the study was to compare the incidence and severity of apical root resorption in patients treated with different orthodontic appliances and to evaluate the effect of treatment duration on the degree of apical root resorption. A further aim was to analyse the degree of apical root resorption in different tooth groups in patients presenting with root resorption. The sample consiste...
