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...

The present study compared the efficacy of cone beam computed tomography using different voxel sizes in the diagnosis of simulated external root resorption. The presence or absence of simulated defects on buccal, mesial and distal root surfaces of 20 premolars was evaluated. The defects were small (0.26 mm in diameter and 0.08 mm deep), medium (0.62 mm in diameter and 0.19 mm deep) and large (1...

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...

OBJECTIVES To investigate root resorption after 6 months of active orthodontic treatment and its relation to possible risk factors. MATERIALS AND METHODS Ninety-seven patients (10-18 years) with a Class I malocclusion and crowding treated with fixed appliance and premolar extractions were examined with cone beam computed tomography before and after 6 months of active treatment. The exposure c...
