Presented is an unusual case of multiple external root resorption. Although the cause of this resorption was not determined, several possibilities are presented. Trauma from occlusion, periodontal andpulpal inflammation, and resorption of idiopathic origin are all discussed as possible causes.

Physical properties of root cementum: Part 24. Root resorption of the first premolars after 4 weeks of occlusal trauma
2014, American Journal of Orthodontics and Dentofacial Orthopedics
In orthodontics, adding restorative materials on occlusal or lingual surfaces is a common method to create a mini-biteplane to increase patients' vertical dimension temporarily to facilitate several treatment procedures. However, this method transmits excessive occlusal forces through the periodontal ligament and causes trauma. In this prospective randomized clinical trial, we measured and compared quantitatively the volumes of root resorption after 4 weeks of occlusal trauma.
Forty-eight maxillary and mandibular first premolars of 12 patients (6 girls, 6 boys) comprised the sample for this study. One side of each patient was randomly selected as the control. On the contralateral side, a light-cured glass ionomer cement (Transbond Plus Light Cure Band Adhesive; 3M Unitek, Monrovia, Calif) was bonded onto the occlusal surface of the mandibular first premolar so that the cement was in contact with the maxillary first premolar. After 4 weeks, both first premolars were extracted. Each sample was imaged using a microcomputed tomography system (1172; SkyScan, Aartselaar, Belgium) and analyzed with specially designed software for volumetric measurements of resorption craters. Furthermore, pain was evaluated with a visual analog scale for 7 days.
There were significant differences in the amounts of root resorption between the control and the experimentally traumatized teeth. No significant difference among the buccal, lingual, mesial, and distal surfaces was found in either jaw. Furthermore, no significant difference existed in the amount of root resorption among the cervical, middle, and apical thirds of both jaws. There was no correlation between age, sex, volume of the root resorption craters, and pain.
Restorative buildups, used to increase the vertical dimension by 2 mm for 4 weeks, caused root resorption along the sides of the teeth during the active bite-increase period.
Bilateral extensive idiopathic apical root resorption in supraerupted maxillary molars: a case report

Citation Excerpt :
Clinically, the resorption involves normal clinical appearance of teeth and periodontal tissues, root resorption associated with vital or endodontically treated teeth, lack of periodontal and periradicular inflammation, alveolar bone levels within normal limits, absence of local etiologic factors, the patient is asymptomatic until very late in the pathologic process; when increased tooth mobility is reported, commonly found as an incidental finding on radiographs, and there is an intramaxillary and intermaxillary symmetric pattern of root resorption. Only 26 clearly identified cases of multiple idiopathic apical root resorptions have been reported in the literature (Table I), all of which were in relatively young individuals, aged from 14 to 39 years, with no gender predilection.4-23 There appears to be a predilection for premolar and molar teeth, in a symmetric pattern.
Multiple idiopathic external root resorptions of permanent teeth are an infrequent phenomenon. A case report of a patient with multiple idiopathic external apical root resorptions is presented. This case is unusual in that extensive resorption is found bilaterally in supraerupted maxillary molar teeth. The pattern of severe resorption affecting only maxillary supraerupted teeth appears to be unique. No significant systemic, dental, or familial findings could be identified as a possible cause.
Update on the etiology of tooth resorption in domestic cats

A different approach for a possible role of occlusal stress in the development of FORL is presented in this article. Surface resorption of cementum and superficial dentin may develop in response to normal masticatory stress [76] and excessive occlusal force [77–80]. Apical root resorption has been linked with bruxism in human beings, although the apical defect in that case report could also have resulted from endodontic disease [81].
Idiopathic root resorption: Report of a case
2000, Journal of Endodontics
A case of multiple idiopathic apical root resorption in a 26-yr-old female patient is presented. A review of the literature revealed that extensive idiopathic root resorption is unusual. Neither local nor systemic etiological factors were found in our case. Examination of parents and siblings did not reveal a familiar tendency. Radiographs and clinical evaluation showed a very poor prognosis for most of the teeth present in the mouth of our patient.
Multiple idiopathic resorption in the primary dentition
1999, Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics
Resorption of primary teeth is a normal physiologic process, except when it occurs prematurely. Resorption of permanent teeth is considered abnormal, and multiple etiologic factors have been implicated. A significant number of cases are represented by idiopathic resorption. Multiple idiopathic root resorption stands as a separate physiologic entity that has been described as affecting the entire permanent dentition. Multiple idiopathic resorption of primary teeth has not been previously reported. A case is described and a differential diagnosis is provided. The specific radiographic diagnostic criteria for this condition affecting the primary dentition are outlined. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 1999;88:501-5)
Extensive idiopathic apical root resorption. A case report
1994, Oral Surgery, Oral Medicine, Oral Pathology
Multiple idiopathic external apical root resorption is an unusual phenomenon. A brief review of cases in the literature is presented as well as a report of a patient with severe resorption. No significant systemic, dental, or familial findings could be identified as a possible cause. Careful chronologic radiographic documentation showed that roots with normal length began to resorb several years earlier, and the resorption continued over a defined period of time, terminating spontaneously before tooth loss or obvious pulp damage. Because the pathogenesis is generally unknown, no specific treatment modalities exist at present.
