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.

External root resorption—fact or fancy

Journal of Endodontics, 1989
A review of external resorption is presented with an emphasis on a wide range of etiological factors. This case report details the possible pitfalls in basing the diagnosis solely on radiographic interpretation.

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 ...

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 ...

Reversal of external root resorption

Journal of Endodontics, 1976
Summary A replanted maxillary left lateral incisor developed extensive external root resorption three months after traumatic intrusion of the tooth and its accidental avulsion during repositioning. The tooth was treated for six months with an intracanal paste of calcium hydroxide and camphorated parachlorophenol.

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 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.

A case of progressive external root resorption

Dental Traumatology, 1991
Abstract This case report describes a radiographical, histological and histochemical study of an extracted mandibular tooth with progressive external root resorption. The cells which appeared to be responsible for the hard tissue resorption showed an intense acid phosphatase activity, similar to that of bone‐resorbing cells.

[Cervical external root resorption].

Nederlands tijdschrift voor tandheelkunde, 2001
Cervical external root resorption is a progressive resorption process occurring at the site of the attached gingiva. It is independent on the condition of the pulp. Prerequisites for its occurrence are a damaged root surface and the presence of vascularized connective tissue. The specific stimulus for the resorption to start is still unknown.
