introduction : furcal perforations are one of the most challenging causes of endodontic failures. several materials including mta have been used for non surgical repair of these perforations. the aim of this study was to compare treatment outcome of furcal perforation treatment in primary molars using root mta and proroot mta. materials and methods: this in vitro study was conducted on 54 prima...

Detection of iatrogenic root perforation during post-space preparation especially in labiolingual plane can be challenging due to the two-dimensional nature of conventional radiography; this can be even more challenging if the cemented post is radiolucent. Cone-beam computed tomography (CBCT) scans were shown to be a valuable diagnostic aid in diagnosis of such cases. However, in this case, the...

A perforation is an artificial communication that occurs between the root canal system and tissues enclosing a tooth. It can be made by dentist during tooth preparation passage into system, or it happen naturally due to resorption dental decay cause connectivity periodontium. Both iatrogenic non-iatrogenic factors lead being perforated. Most often, happens at coronal aspect of Iatrogenic perfor...

Root perforations may occur due to pathological processes or treatment consequences. Such perforations are severe complications and are associated with dramatically compromised endodontic treatment outcomes, especially when bacterial infection is allowed to establish and if the seal between the endodontic space and periradicular tissue is not provided. A new known material, mineral trioxide agg...

internal inflammatory root resorption (iirr) is a rare condition of the root canal and if it is left untreated it may lead to destruction of the surrounding dental hard tissues. odontoclasts are responsible for this situation which can potentially perforate the root. many initiating factors have been mentioned for iirr, almost all causing chronic inflammation in the vital pulp. iirr is usually ...

A detailed understanding of the complexity of root canal systems is imperative to ensure successful root canal therapy. The aim of this study was to evaluate the ability of an optical coherence tomography (OCT) system in imaging root canal walls after endodontic preparation and to correlate these images to histologic sections. Ten extracted mandibular incisors were prepared to size 50 with K-fi...

This article presents the successful surgical management of a failed mineral trioxide aggregate (MTA) orthograde obturation of a tooth with a history of impact trauma and perforated internal root resorption. A symptomatic maxillary lateral incisor with a history of perforation due to internal root resorption and nonsurgical repair using MTA was referred. Unintentional overfill of the defect wit...

statement of problem: mineral trioxid aggregate (mta) cement is widely used for root-end filling, pulp capping, perforation repair and other treatments in endodontics. investigations have shown similar physical and chemical properties for portland cement (type i), root mta and proroot mta. purpose: the aim of this in vivo study was to evaluate the reaction of dog canine pulp after pulp capping ...
