Abstract: Objective An investigation was undertaken to assess potential predisposing factors to invasive cervical resorption. Method and materials A group of 222 patients with a total of 257 teeth displaying varying degrees of invasive cervical resorption were analyzed. Potential predisposing factors, including trauma, intracoronal bleaching, surgery, orthodontics, periodontal root scaling or planing, bruxism, delayed eruption, developmental defects, and restorations were assessed from the patients' history and oral examination. Results Of the potential predisposing factors identified, orthodontics was the most common sole factor, constituting 21.2% of patients and 24.1% of teeth examined. Other factors were present in an additional 5.0% of orthodontically treated patients (4.3% of teeth), and these consisted principally of trauma and/or intracoronal bleaching. Trauma was the second most frequent sole factor (14.0% of patients and 15.1% of teeth). Trauma in combination with intracoronal bleaching, orthodontics, or delayed eruption constituted an additional 11.2% of patients (10.6% of teeth). Intracoronal bleaching was found to be the sole potential predisposing factor in 4.5% of patients and 3.9% of teeth, and an additional 10.4% of patients and 9.7% of teeth showed a combination of intracoronal bleaching with trauma and/or orthodontics. Surgery, particularly involving the cementoenamel junction area, was a sole potential predisposing factor in 6.3% of patients and 5.4% of teeth. Periodontal therapy, including deep root scaling and planing, showed a low incidence, as did other factors, such as bruxism and developmental defects. The presence of an intracoronal restoration was the only identifiable factor in 15.3% of patients and 14.4% of teeth, while 15.0% of patients and 16.4% of teeth showed no identifiable potential pedisposing factors. Conclusion These results indicated a strong association between invasive cervical resorption and orthodontic treatment, trauma, and intracoronal bleaching, either alone or in combination.

External root resorption.
TL;DR: Root resorption is a pathological process initiated by specific clastic cells which remove the organic and mineral components of dental hard tissues and requires active and prompt endodontic preparation and medication to allow the control of clastic activity.

Invasive cervical resorption: clinical and radiological diagnosis and treatment of 3 cases.
TL;DR: The clinical and radiological diagnoses and treatment modalities of invasive cervical resorption in 3 patients were described, two of the 3 cases were incidental radiographic findings and the teeth concerned were symptom free.

TL;DR: Maxillary anterior teeth were the most affected in a Taiwanese population and showed no difference in sex or age, and Traumatic injury, periodontal treatment, and orthodontic treatment were the significant predisposing factors.

Managing discoloured non-vital teeth: the inside/outside bleaching technique.
TL;DR: The importance of preventing and eliminating the potential for discoloration will be highlighted and a detailed technical account on the application of the inside/outside bleaching technique is included, with several clinical examples.

Failure of treatment of impacted canines associated with invasive cervical root resorption.
TL;DR: ICRR is a frequently undiagnosed or unrecognized cause of failure of orthodontic resolution of impacted canines and should be distinguished from replacement resorption and CBCT should be used for its early detection and accurate assessment of potential damage to adjacent anchor teeth.

Root resorption--etiology, terminology and clinical manifestations.
TL;DR: This paper is an attempt to summarize knowledge on root resorption from the point of view of clinical relevance and to present a revised terminological system that corresponds to the present understanding of the resorptive processes in teeth.

External resorption associated with bleaching of pulpless teeth
TL;DR: The clinical circumstances of the cases described in this report strongly suggest such a relationship between external resorption of cervical crown and root structure and bleaching of endodontically treated pulpless teeth.

Incidence of external root resorption and esthetic results in 58 bleached pulpless teeth
TL;DR: The results caution against indiscriminate use of bleaching with hydrogen peroxide, and emphasize the importance of preventive measures and postoperative follow-up of bleached pulpless teeth.

Effect of cementum defects on radicular penetration of 30% H2O2 during intracoronal bleaching
TL;DR: The penetration of hydrogen peroxide was significantly higher in teeth with cementum defects at the cementoenamel junction than in those without defects and the penetration of H2O2 penetrating through open dentin tubules can initiate an inflammatory reaction which could result in root resorption.

Incidence of invasive cervical resorption in bleached root-filled teeth.
TL;DR: It was found that a total of four teeth from the sample group (1.96 per cent) had developed invasive cervical resorption during the review period, and all of these teeth had a history of traumatic injury and the level of gutta-percha was at the CEJ.
