Treatment of non-vital immature teeth with apical periodontitis has always been a challenge in Endodontics. Regenerative endodontic treatment (RET) has been successfully used for the management of these cases. The aim of this study is to present a case of RET used for the retreatment of a previously endodontically treated permanent tooth with an open apex. A 14-year-old boy with a poor endodont...

Background: The aim of the present study was to evaluate canal transportation and centering ability ProTaper, HeroShaper two Ni-Ti rotary systems developed for retreatment (ProTaperRetreatment R-Endo). Materials Methods: One hundred twenty mesial canals mandibular molars with curvatures between 30-40 degrees radii 4-9 mm were embedded in a modified muffle system. teeth randomly divided into 8 g...

O retratamento não cirúrgico é atualmente a terapia mais afetada na Endodontia em termos de desfecho clínico. presente estudo tem como objetivo avaliar estratégias modernas para abordagens complementares remoção material obturador. Assim foi realizada uma revisão narrativa da literatura nas bases dados PubMed. Cochrane Library e Web of Science com as seguintes palavras-chave diferentes ordens: ...

Adequate removal of the previous filling material may be pivotal to a favorable outcome root canal retreatment teeth with post-treatment periodontitis in order permit access irrigants and medicaments persistent bacteria. However, even recent technological advances, including introduction specially designed instruments, no technique has been shown predictably promote complete removal. Supplement...

introduction: advantages of endodontic treatments over tooth extraction have increased the demands for these treatments. success rate of these treatments is generally lower than the primary root canal therapies. recently, single visit treatments have gained more popularity. but, the influence of completing retreatment in a single appointment on success of the treatment is still a controversy. t...

The benefits of using sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA) as endodontic irrigants, and calcium hydroxide as an inter-appointment medicament, are well known to dentists. Many steps undertaken during endodontic treatment and retreatment are rather mechanical in nature, and less attention is committed to understanding the biological issues underlying endodontic t...

Root resorption is a pathological process involving loss of hard dental tissues. It may occur as a consequence of dental trauma, orthodontic treatment, and bleaching, and occasionally it accompanies periodontal disease. Although the mechanism of resorption process is examined in detail, its etiology is not fully understood. Wide open apical foramen is more difficult to manage and the root canal...

invasive cervical resorption is a condition that affects the root surface area below the epithelial attachment. multiple treatment modalities are advocated, involving exposure of the invasive defect, removal of the granulation tissue and sealing with various restorative materials. this report demonstrates conservative treatment of a patient presenting with peri-apical periodontitis in upper rig...
