Bilateral External Root Resorption

The Journal of the American Dental Association, 1980
Root resorption in bilateral maxillary canines was diagnosed in two patients who had histories of orthodontic treatment of the canines when the patients were teenagers. Periodontal surgery exposed the resorbed root areas. Surface restorations and endodontic therapy using guttapercha as the filling material completed therapy.

Differential diagnosis of internal and external root resorption

Journal of Endodontics, 1976
An effort has been made to arrive at a predictable method for correctly differentiating internal and external root resorption. The criteria for the differential diagnosis are presented.

Orthodontic external root resorption—Endodontic considerations

Journal of Endodontics, 1983
External root resorption in posttreatment orthodontic patients, if severe, may jeopardize the retention of the tooth or teeth involved. Numerous studies (1-5) have been undertaken to determine the relationship between the frequency and severity of external root resorption and orthodontic movement.

External root resorption: An experimental radiographic evaluation

Oral Surgery, Oral Medicine, Oral Pathology, 1989
Radiographs of a human mandibular premolar, in which five holes (resorptive defects) of differing diameters were drilled before its replacement into a human mandible, were evaluated by 11 dental faculty members. The radiographs were made at various exposure times and angulations. The observers' results were evaluated statistically.

External Root Resorption — Part II

Australian Endodontic Newsletter, 1996
AbstractRoot resorption is a pathological process initiated by specific clastic cells which remove the organic and mineral components of dental hard tissues. Clastic cell activity in teeth is associated with a number of factors which include biomechanical forces, mechanical, surgical and chemical trauma, endodontic microorganisms and their toxins ...

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

[External root resorption].

Schweizer Monatsschrift fur Zahnmedizin = Revue mensuelle suisse d'odonto-stomatologie = Rivista mensile svizzera di odontologia e stomatologia, 2006
Root resorption may be a physiological (resorption of deciduous teeth) or a pathological process (resorption of permanent teeth). In the latter case an external and an internal form of resorption can be distinguished. Root resorption may occur on one tooth or on several teeth within a dentition and it may be caused by trauma, periodontitis, orthodontic

External cervical root resorption following bleaching

Journal of Endodontics, 1986
A case of external cervical root resorption is reported as a sequela to internal bleaching techniques and possible trauma. The etiology of cervical root resorption is reviewed. Treatment implications are also discussed with emphasis on prevention. The clinician must consider the cosmetic benefits of bleaching in light of the potential risk of root ...

Multiple external root resorption. Case report

Australian Dental Journal, 1993
AbstractA case of a patient with multiple external root resorption affecting principally the molars and premolars is described. This case is unusual in that although both right and left molar and premolar teeth are involved, the resorption is worse on the left side and affects only the distal roots of the molars.

Effect of Allergen Sensitization on External Root Resorption

Journal of Dental Research, 2013
In orthodontic tooth movement (OTM), we should be concerned about external root resorption (ERR) as an undesirable iatrogenic problem, but its mechanisms are not fully understood. Since our previous epidemiologic studies found that patients with allergic diseases showed higher rates of ERR during orthodontic treatment, we explored ...
