Causes Of Failure

Background: In medical practice, clinicians come across a lot of obstacle during a treatment , that can lead to a failure, like other dental treatments, endodontics too can fail. Inappropriate mechanical debridement, persistence of bacteria in the canals and apex, poor obturation quality, over and under extension of the root canal filling, and coronal leakage are some of the commonly attributable causes of failure. Despite the high success rate of endodontic treatment, failures do occur in a large number of cases and most of the times can be attributed to the already stated causes. Purpose: Endodontic retreatment of a failure is required by the increased desire to preserve the tooth on the dental arch, preventing the need for dental extraction that may have adverse consequences in terms of functional and psychological effect on patients. Case: This article presents a case report about dental retreatment with 2 common failure, that was under filling obturation and non-fit post. Case management: The failure was corrected with endodontic retreatment, and finally restored with fiber post and porcelain fused to metal crown. Conclusion: Endodontic retreatment was done successfully on underfilling obturation and non-fit post. The patient was satisfied with the result.

Causes Of Failure

ABSTRACTInappropriate mechanical debridement, persistence of bacteria in the canals and apex, poor obturation quality, over and under extension of the root canal filling, and coronal leakage are some of the commonly attributable causes of failure. Despite the high success rate of endodontic treatment, failures do occur in a large number of cases and most of the times can be attributed to the already stated causes. With an ever increasing number of endodontic treatments being done each day, it has become imperative to avoid or minimize the most fundamental of reasons leading to endodontic failure. This paper reviews the most common causes of endodontic failure along with radiographic examples.

Root Canal Retreatment

Background: Iatrogenic complications such as accidental perforation of the root or the floor of the pulp chamber may occur. Case Report: Patient was referred for root canal retreatment of the mandibular left second molar with periapical lesion evidenced through radiographic examination. During post removal, iatrogenic perforation occurred at the mesial face of the distal root. After clinical localization of the perforation and bleeding control, MTA was applied. In a second appointment, the root canal filling was removed and the chemical-surgical retreatment of the canals was performed, followed by the obturation with gutta-percha and sealer. Patient returned after three days reporting no pain. After 6 months, 3, 7 and 10 years of follow-up. Conclusion: Absence of pain, normal periodontal probing and lack of radiolucent area at the region of perforation and the periapices were detected, which evidenced the successful repair of the tooth.

Endodontic Retreatment

It is a well-recognised fact that incomplete cleaning, shaping and obturation of root canals will lead to endodontic failure. Mandibular second premolars usually have a single root and a single root canal. The presence of four separate roots and four root canals is quite rare. Hence, a comprehensive knowledge about the normal canal configuration along with its variations becomes an indispensable pre-requisite to achieve the success of endodontic treatment. Authors hereby present a case of a 26-year-old male patient and describe its succesful treatment of the mandibular second premolar with four roots and four root canals. The clinical implications of this paper aim at establishing an accurate diagnosis of the root canal system using diagnostic aids such as angulated radiographs and making use of advanced endodontic instruments for successful retreatment of endodontic therapy (C+ files and NiTi rotary endodontic instruments).

Endodontic Retreatment

Endodontic retreatment is an attempt to reachieve a healthy periapical after it was previously been carried out an inadequate or reinfected endodontic retreatment that has been filled due to the leakage of apical and coronal. One stage in this retreatment is an uptake of obturasi material using hedstrom file (H-file). The solvent material used in this endodontic retreatment is xylol. Case report. A 22-year-old male patient came to the Clinic of Conservative Dentistry Dental Hospital Prof. Soedomo, Faculty of Dentistry, Gadjah Mada University (UGM) wanted to treat his mandibular second right premolar (45) that has been painful since two months ago. The tooth had root canal treatment one year ago. The pain suddenly appears and disappears as soon as the patient consumes painkillers. Dental preoperative (periapical) radiograph tooth 45 showed a picture of gutta percha root canals and radiolucent images at the tip of the root of the tooth. Diagnosis of tooth 45 is non-vital tooth after root canal treatment accompanied by apical, symptomatic periodontitis. The operator performed a root canal treatment by dismantling the restoration on the occlusal part of tooth 45 and taking gutta percha using a hedstrom file followed by treatment of the root canal, crown lengthening, installation of individual formable fiber post and porcelain fused to metal crown. Conclusion. Retreatment of root canal treatment with non-surgical methods still can be conducted effectively and obtain good results with the final treatment results in smaller lesions in the apical portion of tooth 45.

Canal Morphology

A comprehensive knowledge of the root canal morphology and its variations is a basic requisite for the success of the endodontic treatment. Mandibular molars may present a third or additional root, which if located lingually is called radix entomolaris or bucally is referred as radix paramolaris. This case report shows an endodontic retreatment of a radix entomolaris and details some variations in the approach to guarantee a successful terapy.

<p><strong>Objective: </strong>Failures in endodontic treatment may occur by several reasons. Endodontic retreatment is an interesting alternative to manage this clinical problem. However, it is not possible to completely remove the root canal filling by any current retreatment technique. The aim of this study was to evaluate the presence of residual root canal filling materials after endodontic re-instrumentation. <strong>Material and Methods:</strong> Sixty extracted anterior human teeth were prepared by step-back technique with Flexofiles, K-files and Gates-Glidden (GG) burs. Between the use of each file or bur, root canals were irrigated with sodium hypochlorite (NaOCl). Smear layer was removed by irrigation with ethylenediaminetetraacetic acid and NaOCl. After drying with paper points the root canals were randomly divided into 5 groups (n = 12), according to filling material: Resilon cones/Real Seal sealer or gutta-percha cones and Endofill, Sealapex, AH Plus or MTA Fillapex sealers. After one week, root canal fillings were removed using Eucaliptol and K-files. Root canals were re-instrumented with K-files and GG burs sized larger than the first ones. The removal of root canal filling material was analyzed by radiography and scanning electron microscopy (SEM). Statistical analysis was performed using Binary Logistic Regression test (P &lt; 0.05). <strong>Results: </strong>Radiographic and SEM analysis showed that material from the<strong> </strong>MTA Fillapex group was better removed than that from Endofill, Sealapex, AH Plus and Real Seal groups. <strong>Conclusion: </strong>After re-instrumentation<strong>, </strong>MTA Fillapex group showed less remnants into the root canals than Endofill, Sealapex, AH Plus and Real Seal groups. Residual material was most often found in the apical third.</p><p><strong>Keywords </strong></p><p>Dental radiography; Endodontic retreatment; Root canal filling materials; Scanning electron microscopy.</p>

Mandibular First Premolar

Abstract Background Understanding the anatomical morphology of the root canal is key for successful root canal treatment. The aims of this case presentation are to report a unique case of root canal treatment involving five root canals in the mandibular first premolar and to highlight the importance of variation in root canals of mandibular first premolars in clinical practice. Case presentation A 25-year-old male with intermittent pain in relation to the lower right posterior teeth over 3 weeks was diagnosed with symptomatic pulpitis in tooth #44. Four root canals were found, including mesiobuccal, distobuccal-1, distobuccal-2, and distolingual roots, and the Mtwo rotary system was used for root canal preparation. The four root canals were filled after 2 weeks, when a fifth canal was found, located in the buccal cavity. The fifth canal was confirmed to be the mesiolingual root canal by cone beam computed tomography (CBCT) and was found to be curved. After completion of the root canal filling, CBCT was performed, and a three-dimensional root canal image was reconstructed. After 1 week of observation, the tooth was repaired using composite resin filling. Conclusions This is the first case presentation of a fifth canal of the mandibular first premolar and advances our understanding of variations in the anatomy of the mandibular first premolar. This case report provides a reference for the treatment of mandibular first premolars.
