UNLABELLED Orthodontically induced root resorption is an irreversible process that can have medical, ethical and legal implications. AIM The objective of this research was to identify morphological risk factors, in order to prevent it. MATERIAL AND METHODS We realized a retrospective study on 50 patients and made correlation between the prevalence and gravity of radiological identified root...

Root shortening as a result of apical root resorption is an undesirable consequence of orthodontic treatment. The objective was to determine the prevalence of external apical root resorption in a sample of Sudanese orthodontic patients treated with fixed appliances and to evaluate the association of treatment duration, age, gender and the type of malocclusion on the degree of external apical ro...

This clinical study evaluated factors related to root resorption before (T1) and after (T2) orthodontic treatment. Ninety-six subjects between 9 and 34 years (34 males and 62 females) who had been treated using fixed appliances for at least 1 year and who had panoramic radiographs at T1 and T2 were selected. The relationship between root resorption at T1 and T2, with regard to gender, age, extr...

AIM To evaluate the presence of root resorption in the lateral incisor after active orthodontic treatment in the early mixed dentition. METHODS Twenty-six children treated at the Children's Clinic of the Schulich School of Medicine and Dentistry at the University of Western Ontario were examined radiographically for lateral incisors root resorption before and after early active treatment to a...

Root resorption is the destructive process of the cementum and/or dentine layers of a tooth root due to clastic cell activity which leads to a subsequent loss root structure of a tooth. This process may be physiological or pathological. Physiological root resorption of deciduous teeth naturally occurs when the permanent teeth begin to erupt. It may also occur to a small degree in the permanent ...

Odontoclastic root resorption is a significant clinical issue in relation to orthodontic tooth movement, and resorption of the roots of primary teeth is an intriguing biological phenomenon. The functional coordination of the OPG/RANKL/RANK system seems to contribute not only to alveolar remodeling, but also to resorption during orthodontic tooth movement and physiological root resorption. Serum...

This case report presents an unusual complication, cervical root resorption, after a conventional connective tissue grafting procedure and tetracycline root conditioning. The recession was 7 mm high, with 0.5 mm of keratinized tissue present, a 2-mm probing depth, and was classified as Miller Class III. The clinical result was satisfactory and 5 mm of root coverage was achieved. However, after ...

background: this randomized trial was undertaken to investigate the effect of experimentally induced allergy on orthodontic induced root resorption. materials and methods: a total of 30 wistar rats were divided randomly into test and control groups. starting from the first 3 days, the rats in the test group were injected intra-peritoneally by 2 mg ovalbumin as allergen and 0.5 mg alume as adjuv...

STATEMENT OF PROBLEM One of the major outcomes of orthodontic treatment is the apical root resorption of teeth moved during the treatment. Identifying the possible risk factors, are necessary for every orthodontist. PURPOSE The aim of this study was to compare the rate of apical root resorption after fixed orthodontic treatment with standard edgewise and straight wire (MBT) method, and also t...
