Use of an existing post to rerestore an endodontically treated tooth with a new post-and-core complex and crown: a case report.

Replacement of a post-and-core restoration that has failed because of caries or fracture presents a restorative challenge to the general dentist. This case report describes a new technique that enables the utilization of an unremovable preexisting post in the fabrication of a new post-and-core complex. This complex served as a foundation for a restoration that restored form and function to the patient's dentition.     

Use of a bondable reinforcement fiber for post-and-core buildup in an endodontically treated tooth: a case report.

The restoration for an endodontically treated tooth should be conservative and should not increase horizontal and vertical forces. A recently developed bondable reinforcement fiber is reported to be an alternative to conventional post materials because of its esthetic qualities, mechanical properties, and the neutral color of the reinforcing material. This article describes the treatment of one patient, in whom a bondable polyethylene ribbon was used as a post-and-core build-up material.     

Radicular cyst associated with endodontically treated deciduous tooth: a case report

This article presents a case report of radicular cyst associated with an endodontically treated deciduous second molar causing displacement of the permanent successor, with accompanying buccal expansion. Cystic sac was removed surgically along with the involved tooth under general anesthesia. Healing was uneventful. Histopathologically the cystic sac was consistent with the features of radicular cyst. Unusual amorphous, eosinophilic, atubular material incorporated within the cystic epithelium was observed.     

A case of mistaken identity: periapical cemental dysplasia in an endodontically treated tooth

Abstract A case of a patient with a history of root canal treatment and re-treatment and a persistent periapical radiolucency is reviewed. Following surgery, biopsy material was submitted and diagnosed as periapical cemental dysplasia (PCD). With careful diagnosis, PCD should be readily differentiated from endodontic pathosis, thus avoiding unnecessary root canal treatment. In this case, surgery was necessary to rule out other inflammatory disease or benign odontogenic entities.     

Use of MTA and intracanal post reinforcement in a horizontally fractured tooth: a case report

Abstract –  Root fracture is one of the consequences of dental traumatisms. The possibility of saving the fractured tooth depends on the level of the fracture and also on pulp vitality. This case report describes the use of MTA in association to an intracanal post to reinforce a maxillary central incisor with horizontal root fracture in its cervical third.     

牙体缺损桩核修复的系统评价

目的评价各种牙体缺损桩核修复方法失败率,为临床应用提供指导。方法通过计算机及手工检索有关根管治疗后桩核修复的临床随机对照和半随机对照试验,评价纳入文献的质量并进行系统评价。结果共检索出2 100篇文献,有6篇符合纳入标准,其中3篇为比较纤维桩和金属桩修复效果的试验,Meta分析结果显示,使用纤维桩和金属桩修复短期疗效差异无统计学意义;3篇为比较使用纤维桩和不使用桩修复效果的试验,Meta分析结果显示4个侧壁缺失有箍效应并已行根管治疗的患牙,使用纤维桩修复较不使用桩修复失败率低。结论 4个侧壁缺失的患牙应使用纤维桩修复;现有的研究结果尚不能判断纤维桩与金属桩修复根管治疗后牙体缺损的临床效果何者更为优越,仍需更多临床随机对照试验的结果进行验证。     

Draining fistulas associated with an endodontically treated tooth

A case of periapical actinomycosis is presented. Although apparently uncommon, actinomycosis should be considered when a chronic periapical lesion, often in the maxilla, is associated with an endodontically treated tooth or a previous history of trauma. Histologic examination of the tissue or the presence of "sulfur granules" in the exudate will usually establish the diagnosis. Treatment consists of local curettage and antibiotic therapy.     

Inflammatory follicular cyst associated with an endodontically treated primary molar: a case report

This is a case study of an inflammatory follicular cyst associated with an endodontically treated deciduous molar with radiographic and microscopic diagnosis. This cystic lesion represents a typical follicular cyst that arose in association with periapical inflammation from a non-vital deciduous molar and involved the follicle of the unerupted successor premolar. This paper describes the case and discusses diagnosis, histogenesis, and controversies regarding terminology.     

Apical healing of an endodontically treated tooth with a temporary restoration

A 35-yr-old, healthy male presented to the graduate endodontic clinic at Indiana University School of Dentistry for treatment of tooth #26. Two and one-half yr after treatment, the patient returned to the dental school for comprehensive treatment. The canal access opening had been restored with an intact interim restorative material restoration. The tooth was asymptomatic, and radiographic examination showed evidence of apical healing. In this article, a review of the literature concerning crown-down leakage is presented. A case report is given in which healing occurred after the tooth was restored with only an interim restorative material for an extended period of time.     

Management of a vertically fractured endodontically treated tooth

The case of a vertically fractured endodontically treated tooth in which an amalgam platform was constructed on the root face is presented. A modified post crown was erected on this base. No exploratory endodontic surgery was performed. Over a 2-year follow-up period, neither the clinical nor the radiographic appearance of the tooth had deteriorated.     

Cermet reinforcement of a weakened endodontically treated root: a case report.

Many clinical applications have been recommended for glass-cermet cement because of its improved properties compared to the original glass-ionomer cements. It has also been accepted as a dentinal substitute that can strengthen teeth. In this paper, an additional clinical application for glass-cermet cement, the reinforcement of weakened endodontically treated roots, is suggested. This technique is in keeping with the trends of tooth conservation and the use of an adhesive restorative material in the restoration of severely damaged teeth by a conservative approach.     

Restoration of the endodontically treated tooth

It has been the purpose of this article to provide a rationale for the restoration of endodontically treated teeth. Treatment recommendations have been made in the areas of post design, placement technique, cements, core materials, and definitive restorations, based on a review of the clinical and laboratory data.     

The assessment of the endodontically treated tooth

This paper reviews the assessment of success and failure following endodontic treatment and highlights the fact that many referrals for specialist management of endodontic failure do not take into consideration established guidelines in this important area.
