Obturation of iatrogenically damaged root canals with injectable thermoplasticized gutta-percha: a case report

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.

Triple Antibiotic Paste

In teeth with pulpal and periapical infection, various group of microorganisms are present. Inhibition of the growth of these microorganisms and suppression of their antimicrobial activity play a crucial role in the success of the endodontic management. Triple antibiotic paste has been reported to have an excellent antimicrobial efficacy and it can be useful in management of teeth with severe infection. A 12-year-old female child reported with pain and swelling in relation with a lower left first permanent molar. Clinical examination of the tooth revealed deep occlusal caries and dentoalveolar abscess. Radiographically, the carious lesion was seen involving the pulp with periodontal ligament widening and inter-radicular bone loss was observed (endo-perio lesion). Considering the position of the tooth and its strategic importance, a conservative approach to salvage the tooth using Triple Antibiotic Paste (TAP) as a medicament was employed with complete radiographic healing by 12 weeks. Subsequent obturation using lateral condensation with gutta percha followed by composite restoration and preformed stainless steel crown was performed. This case report focuses on the endodontic management of perforated first permanent molar with compromised periodontal support and significant bone loss TAP as medicament and Mineral Trioxide Aggregate (MTA) as perforation repair material. Based on the results it can be concluded that Triple Anitibiotic Paste (TAP) can be effective in the disinfection and sterilization of the root canals and repair of complex lesions.

Root Canal System

Introduction: Knowledge of the anatomy and root canal system is of fundamental importance for a successful endodontic treatment. Maxillary canines unusually possess two root canals. Aim: The present study aims to present a maxillary canine with two roots and two canals through a clinical case. Case report: A male patient was referred for the treatment of a root perforation of the tooth 23. Clinical examination revealed the presence of vestibular fistula and mild pain with vertical and horizontal percussion. Through a tomographic examination, the presence of two roots and two root canals was observed in addition to a radiolucent lesion at the middle third of the roots but without perforation in the middle third. Coronary opening and the localization of the vestibular and palatal canals were performed. The root canal length was performed with Romi Apex A-15® foraminal locator and instrumentation was conducted by using Protaper Next® system. Due to the presence of fistula, calcium hydroxide manipulated with propylene glycol was used as intracanal medication for 30 days. After this period, the root canals were filled with gutta-percha and AH Plus® cement and a new tomographic examination was undertaken, which confirmed the complete filling of the root canals and the absence of root perforation. Conclusion: Given the above, endodontic professionals shall be aware of possible anatomical variations and make use of auxiliary resources when appropriate, such as cone beam computed tomography (CBCT), to ensure correct diagnosis and, consequently, a successful root canal treatment.

Root Canal Morphology

Introduction. This clinical case report presents the successful endodontic treatment of a maxillary second molar that has a mandibular molar-like anatomy with no palatal root and with each of its roots containing two separate root canals. Cone-beam computed tomography (CBCT) was used to confirm this unusual anatomy.Methods. A 34-year-old male patient was referred to the Department of Endodontics at Inonu University’s Faculty of Dentistry because of severe pain in his right maxillary second molar. Clinical and radiographic examinations identified unusual roots and root canals anatomy, and CBCT was planned in order to understand the nature of these variations. Cleaning and shaping procedures were performed using the crown down technique with Sybron Endo (Glendora, CA, USA) rotary instruments, and endodontic treatment was completed with gutta-percha cones and AH Plus resin sealers using the cold lateral compaction technique.Conclusions. The maxillary second molar exhibits aberrations and variations in terms of the numbers and configurations of its roots and root canals, and CBCT can be a useful imaging technique in endodontics.

Aim: This Case Report describes two rare cases of clinical management of maxillary first molars with six root canals with special reference to radiographic interpretation and diagnosis. Background: The study reports 2 clinical cases of endodontic treatment of maxillary first molars with six root canals. Case Description: The access cavity was prepared using a slow speed round bur. The teeth were diagnosed with irreversible pulpitis and then anesthetized for an endodontic access cavity preparation. Clinical evaluation of the internal anatomy revealed 3 principle root canal systems: mesiobuccal (MB), distobuccal (DB), and palatal in each tooth. The working length was determined and the radiographs were taken for all the roots i.e mesiobuccal, distobuccal and palatal separately after placing instruments in each. The cleaning and shaping was performed using ProTaper Universal rotary instruments. Irrigation between each instrument was done. The canals were dried and obturation was performed using cold lateral compaction of gutta-percha and a resin-based sealer. The teeth were then restored with a posterior composite restoration. The patients were advised a full-coverage crown. Conclusion: A good knowledge of tooth morphology, careful interpretation of angled radiographs, proper access cavity preparation and a detailed exploration of the interior of the tooth is needed to ensure a proper endodontic treatment. Clinical Significance: Prevalence of teeth with such complex internal anatomy is a rare anomaly. However, a sound knowledge of the internal anatomy can aid in its adequate management.

Root Canal System

Introduction. The success of endodontic treatment depends on the adequate biomechanical preparation and obturation of the entire root canal system. The untreated or poorly debrided/obturated root canals are among the most frequent causes of endodontic treatment failure. The endodontic treatment of maxillary molar has the highest failure rates due to the complexity of their root canal anatomy. The aim of the study is to present the endodontic treatment of maxillary second molar with two roots and two canals. Case report. The clinical case report presents the endodontic treatment of maxillary second molar with two roots and two canals in a patient, aged 32 years. After the analysis of preoperative diagnostic radiograph, opening the pulp chamber and access cavity preparation, two canal orifices were localized. After the biomechanical preparation, root canals were obturated with the Gutta-percha points and sealer during the same visit. Conclusion. Although maxillary second molar most commonly varies in terms of the number of root canals in the buccal roots, less common variations in anatomical and morphological traits, such as the presence of two roots and two canals, should be considered during endodontic treatment.

The mandibular canine is usually considered a single-rooted tooth with a single root canal. However, two canals and more rarely two roots may also occur. This paper reports the case of a patient with bilateral mandibular canines with two roots and two root canals. The initial periapical radiographs of the mandibular right and left canines for endodontic treatment revealed the presence of two roots in each tooth. After coronal opening, the cervical third was prepared with a SX file of the ProTaper® system and root canal length was confirmed using Root ZX electronic apex locator. Root canal preparation was completed with the series of ProTaper® instruments and the root canal was filled with gutta-percha and an epoxy resin-based endodontic sealer according to Tagger's hybrid technique. The final radiographs showed two well-obturated canals ending at the electronically located apexes. The 6-month posttreatment follow-up showed apparent clinical and radiographic success. Clinicians should always consider the presence of anatomical variations in the teeth during endodontic treatments. Despite the low prevalence, variations may occur in the number of roots and root canals of mandibular canines, as demonstrated in this case report.

Background: This work aimed to evaluate the efficacy of sonic agitation of a binary mixture of solvents (methyl ethyl ketone/tetrachloroethylene) on filling remnants removal and compare the effects of solvent agitation with the enlargement to the next instrument size. Methods: Twenty-four mandibular incisors were prepared with ProTaper Next (X1, X2) and obturated with the single-cone technique and AH Plus sealer. The teeth were retreated with ProTaper Universal Retreatment and ProTaper Next and divided into two groups (n = 12) according to the final instrument (X3 or X4). All canals were submitted to a supplementary procedure consisting of a mixture of solvents―methyl ethyl ketone/tetrachloroethylene, agitated with EndoActivator. The volume of filling remnants was assessed through micro-computed tomography in the apical 5 mm. Statistical analysis was performed with a significance level of 5%. Results: The supplementary procedure of agitation of the solvent mixture was beneficial in both groups (p < 0.05). There were no statistically significant differences between canals re-prepared until X4 and canals re-prepared until X3 plus solvent (p > 0.05). Conclusions: An additional step with a two-solvent solution potentiated by EndoActivator showed to be very effective for the removal of gutta-percha and resinous sealer remnants from apical root canals of mandibular incisors, avoiding further enlargement.
