Progressive, Generalized, Apical Idiopathic Root Resorption and Hypercementosis

Journal of Periodontology, 2005
Background: Root resorption is a multifactorial process that results in loss of tooth structure. The causes of root resorption may vary, leading to several types of resorptions. Some factors have been identified and may be categorized into physiological resorption, local factors, systemic conditions, and idiopathic resorptions.

Apical Root Resorption after Lingual Orthodontic Therapy

Journal of Orofacial Orthopedics/Fortschritte der Kieferorthop�die, 2003
Apical root resorptions are among the undesirable side effects of orthodontic therapy. The aim of the present study was to investigate radiologically whether and to what extent resorptions occur in patients treated solely with a fixed lingual appliance, as well as the pathogenetic relevance of the extent and direction of the therapeutically induced ...

Apical root resorption in orthodontically treated adults

American Journal of Orthodontics and Dentofacial Orthopedics, 1996
This study analyzed the relationship in orthodontically treated adults between upper central incisor displacement measured on lateral cephalograms and apical root resorption measured on anterior periapical x-ray films. A multiple linear regression examined incisor displacements in four directions (retraction, advancement, intrusion, and extrusion) as ...

Genetic predisposition to external apical root resorption

American Journal of Orthodontics and Dentofacial Orthopedics, 2003
External apical root resorption (EARR) can be an undesirable sequela of orthodontic treatment. Previous studies have suggested that EARR has a substantial genetic component. Linkage and association were examined between polymorphisms of the interleukin IL-1 (IL-1A and IL-1B) genes and EARR in 35 white American families. Buccal swab cells were collected

Periodontal fiber attachment and apical root resorption

Dental Traumatology, 1988
Abstract Apical root resorption is frequent after physiological and orthodontic tooth movement. Current resorption concepts emphasize a protective effect due to cell and fiber attachment to surfaces at risk. The present study investigated relationships between fiber attachment to the root surface and susceptibility to root resorption.

Orthodontics and External Apical Root Resorption

Seminars in Orthodontics, 2007
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,

Assessment of apical root resorption using digital reconstruction.

Dentomaxillofacial Radiology, 1998
To assess the in vitro and in vivo accuracy of a mathematical computer-based reconstruction of two images that are not taken with the same recording geometry for the measurement of apical root resorption following orthodontic treatment.A gold standard for root resorption in vitro was developed from 10 extracted upper central incisors using calipers ...

Imaging of External Apical Root Resorption

2020
The importance of quality images in the clinical diagnosis and treatment of EARR cannot be understated. The apex is difficult to visualize accurately, and quality images are needed. Digital panoramic radiographs are the most utilized and available throughout the world.

[Apical root resorption during orthodontic treatment].

Fortschritte der Kieferorthopadie, 1989
Pre- and posttreatment radiographs of 2050 orthodontically treated patients were examined and apical root resorptions of more than 2 mm were identified. 30 patients (211 teeth) were affected. Treatment characteristics and objectives of this group (with severe apical root resorption) were compared to a treated group of 30 patients (with no resorption ...
