The current literature on multiple idiopathic cervical root resorption (MICRR), a rare and aggressive form of external root resorption, is limited to case reports and series. Therefore, we performed a systematic review of this condition. A comprehensive search of PubMed, Embase, Web of science, Cochrane Library, CNKI, and WANFANG was conducted using key terms relevant to MICRR, supplemented by a grey literature search. Risk of bias was assessed using Cochrane's and Joanna Briggs Institute's tools. A total of 36 studies with 47 cases were included. MICRR is more common among younger females and may be related to hormonal changes and denosumab use. Initially, the premolars are usually affected but all permanent teeth may eventually be involved. Cone-beam computed tomography is recommended for diagnosis and assessment of resorptive lesions. The management is focused on complete removal and restoration of the resorptive tissue to maintain the tooth's structural integrity. However, MICRR usually has a poor prognosis. Due to its invasive and aggressive behavior, MICRR requires greater attention. 相似文献

Aim: External apical root resorption is a common consequence of orthodontic treatment. A number of treatment-related factors have been implicated in the pathogenesis of root resorption in orthodontic patients; however recent evidence suggests that genetic factors also play a major role in the development of this condition. Herein, we review prevalence, diagnosis and aetiology of root resorption with a particular emphasis on the effect of genetic variation and orthodontic forces, as well as discuss effective prevention strategies. 相似文献

External resorption is sequelae of necrotic periodontal membrane over a large area of root following an injury to the tooth. This usually occurs after severe dental injuries such as intrusion, severe luxations or exarticulation injuries complicated by a prolonged extra oral period. This case report presents a clinical and radiographic follow up (13 months) of treatment of inflammatory external root resorption on maxillary central incisor using Vitapex. Gradual healing of resorption was observed radiographically with no tenderness or pathological mobility. 相似文献

BACKGROUND: Cases of generalized idiopathic root resorption have been reported in the literature. However the majority of previously reported cases have affected adults, and it has been rare that a possible link to a medical condition has been found. CASE REPORT: The subject of this case report was 11 years old when generalized root resorption was first diagnosed. This case report is unusual in that the resorption may be connected to a bone dysplasia. The possible medical diagnoses and links to tooth resorption have been discussed for this very rare case. CONCLUSION: The investigation into the exact diagnosis of the patient and the treatment of tooth resorption is still ongoing and has required input from many disciplines of Medicine and Dentistry. 相似文献

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. 相似文献

Extracanal invasive resorption originates in the periodontal ligament, making it difficult to determine during treatment whether all resorption cells have been eliminated. Consequently, periodontal defects and recurrence of the process are quite common. This process can occur supraosseously or subosseously and treatment may or may not include endodontic therapy. The pathogenesis, diagnosis, and treatment modalities are presented along with a clinical case with an 18-month follow-up as an example of the challenges associated with treatment of this lesion. 相似文献

Dental root resorption 总被引:4,自引:0,他引:4

This article presents a review of physiologic mechanisms involved in various types of root resorption that may be encountered clinically. Included is a brief overview of suggested homeostatic mechanisms of the periodontal ligament and the role of the intermediate cementum in inhibiting root resorption. Root resorption (surface, inflammatory, and replacement) associated with traumatic injuries is discussed, with emphasis on etiology and the ability to provide treatment. The final discussion relates to other types of resorption, based on a classification of internal, cervical, and external resorption associated with periradicular pathosis and resulting from pressure in the periodontal ligament. 相似文献

AIM: To report a rare case of multiple idiopathic apical root resorption in an adult male. SUMMARY: A 27-year-old male with no history of medical or dental disorders was referred by his family dentist for evaluation of extreme root resorption involving the apical region of most of his teeth. A complete haematological investigation was conducted and all the results were within the normal range. Mobility of the teeth was physiologic and no abnormal periodontal pockets were observed. A diagnosis of multiple idiopathic apical root resorption was made. KEY LEARNING POINTS: *Apical root resorption of multiple teeth can be related to no specific aetiology and is known as idiopathic apical root resorption. *It is mostly seen in young adult males; maxillary teeth are more frequently involved. *No preventive or therapeutic regimen is known and monitoring accompanied by periodontal maintenance is recommended. 相似文献

Abstract – The etiology of internal root resorption is not fully understandable, trauma and chronic pulpitis are considered the main risk factors. Usually the process is asymptomatic and diagnosed upon routine radiographic examination. This case report presents a rapid progression of internal resorption related directly to traumatic injury. A 16‐year‐old female arrived at the emergency room after a mild extrusion of the mandibular incisors. The initial treatment included repositioning and splinting of the teeth. Radiographs performed at repositioning and splinting demonstrated normal configuration of the incisor’s roots. Ten months later progressive internal resorption of the left mandibular first incisor was diagnosed. While treating this tooth similar process was detected in the right mandibular second incisor and in the mandibular left second incisor. The lower right first incisor reacted inconsistently to vitality test. As a result of the severe and rapidly progressive nature of the process, root canal treatments were performed in all lower incisors. The follow‐up radiographs demonstrate arrest of the internal resorption process. 相似文献

Idiopathic root resorption of the entire permanent dentition: systematic review and report of a case
Abstract – A rare case of idiopathic root resorption affecting the entire dentition was described. Root resorptions of all of the maxillary and mandibular teeth were coincidentally diagnosed on patient's radiographic examination. The patient's medical and dental findings were non-contributory, other than the increased mobility of upper incisors. No significant familial findings could be identified. Detailed radiographic examination revealed resorption affecting the apical part of the roots, resulting in vertical shortening of the teeth. The character of the resorption was as if a tapering occurred throughout the lateral root surfaces. Involved teeth were endodontically treated and the patient was subsequently followed-up for 18 months. Following endodontic therapy, all periapical lesions demonstrated clinical and radiographic evidence of healing. Endodontic therapy resulted in a high degree of success to stop resorption process and maintain the dentition. 相似文献

目的:系统评价二膦酸盐对正畸治疗中牙根吸收的影响。方法:检索PubMed等数据库中关于二膦酸盐对正畸治疗中牙根吸收影响的随机对照试验文献,并对纳入文献进行质量评估。结果:共纳入9项研究,其中3项为中等级质量,6项为低等级质量。药物剂量、作用力大小和方式、牙根吸收测量方法不同导致只能进行定性分析。二膦酸盐对正畸诱导的牙根吸收的抑制作用具有剂量和时间依赖关系。结论:二膦酸盐可能减轻正畸治疗中牙根吸收的严重程度,但由于纳入文献的质量不高,该结果的临床推衍存在局限性,仍需统一研究方法的大样本、长时间的随机对照实验以进一步研究。 相似文献
