One of the main principles of endodontic treatment is the three-dimensional root canal filling, with a focus on filling the apical third of the root. The management of cases with periapical lesion and severe resorption internal and external, still remains a clinical challenge. Biological approaches of tissue engineering will yield new diagnostic and therapeutic way to repair soft tissue as well...

Root resorption is a physiologic event for the primary teeth. It is still unclear whether odontoclasts, the cells which resorb the dental hard tissue, are different from the osteoclasts, the cells that resorb bone. Root resorption seems to be initiated and regulated by the stellate reticulum and the dental follicle of the underlying permanent tooth via the secretion of stimulatory molecules, i....

Hereditary hemorrhagic telangiectasia (HHT) is an inherited syndrome characterized by mucocutaneous telangiectases that commonly involve the tongue, lips, fingers, and conjunctiva. While root resorption has been reported in association with central hemangiomas of bone, the association of HHT with external cervical root resorption has not been described to date. We report a case of a 57-year-old...

Introduction:Orthodontic treatment is associted with a risk of root resorption.The aim of this study was to determine the risk of moderate and sever root resorption in orthodontic patients treated with fixed orthodontic appliance.   Method:A case-control study was performed on 70 orthodontic treated patients with moderate and sever root resorption and 70 controls matched for age,sex,duration ...

INTRODUCTION This systematic review evaluated root resorption as an outcome for patients who had orthodontic tooth movement. The results could provide the best available evidence for clinical decisions to minimize the risks and severity of root resorption. METHODS Electronic databases were searched, nonelectronic journals were hand searched, and experts in the field were consulted with no lan...

INTRODUCTION The effect of zoledronic acid, a potent and novel bisphosphonate, on tooth movement and orthodontically induced root resorption in osteoporotic animals systemically treated with zoledronic acid as similarly used in postmenopausal patients has not been elucidated. Therefore, this study was undertaken. METHODS Fifteen 10-week-old female Wistar rats were divided into 3 groups: ovari...

The aim of this study was to evaluate the risk of root resorption during orthodontic treatment of patients with aplasia, and to analyse the relative importance of some anamnestic and treatment variables. The subjects comprised 68 orthodontically treated patients with 1-16 congenitally missing teeth. The age of the patients was 11-20 years (mean 15 years). All patients were treated with fixed ed...

Idiopathic root resorption is a very rare phenomenon. Resorption in tooth is brought about by odontoclastic activity. Special mechanisms in the periodontal ligament exist to prevent mineralization of the periodontal ligament and these periodontal ligament cells produce factors that inhibit mineralized tissue resorption and are capable of regulating bone and cementum formation. When this mechani...

The aim of this study was to analyse serum IgG levels and salivary secretory IgA (sIgA) levels in human dentine extract (HDE) before (T0) and 6 months after (T6) orthodontic treatment and to correlate anti-HDE autoantibodies to root resorption. Fifty orthodontic patients were selected, 19 males (15.6 ± 8.5 years) and 31 females (21.4 ± 11.2 years), 19 in the mixed dentition (10.3 ± 1.9 years) a...

root resorption (rr) is defined as the loss of dental hard tissues because of clastic activity inside or outside of tooth the root. in the permanent dentition, rr is a pathologic event; if untreated, it might result in the premature loss of the affected tooth. several hypotheses have been suggested as the mechanisms of root resorption such as absence of the remnants of hertwig's epithelial root...
