INTRODUCTION This article describes 3 cases that presented persistent symptoms after appropriate endodontic treatment. Histopathologic and histobacteriologic investigation were conducted for determination of the cause. METHODS Three cases are reported that presented with persistent symptoms after endodontic retreatment (cases 1 and 2) or treatment (case 3). Periapical surgery was indicated an...

OBJECTIVE The purpose of this study was to determine the factors associated with posttreatment pain in patients receiving root canal retreatment (RCR) and in those receiving initial root canal treatment (IRCT). STUDY DESIGN Eighty four patients scheduled for RCR or IRCT completed questionnaires on pretreatment pain levels (Visual Analogue Scale, 0-100) and demographic data. Diagnosis and orig...

Introduction. Root perforations may occur following endodontic treatment, thus compromising the root integrity and treatment outcome. Case Report. A patient presented with a canal perforation an earlier of upper left lateral incisor (tooth 22). Once diagnosis symptomatic periapical periodontitis was established, decision made to retreat using mineral trioxide aggregate perform apicoectomy. The ...

Instead of extraction this case report presents an alternative treatment option for a maxillary incisor with a vertical root fracture (VRF) causing pain in a 78-year-old patient. After retreatment of the existing root canal filling the tooth was stabilized with a dentine adhesive and a composite restoration. Then the tooth was extracted, the VRF gap enlarged with a small diamond bur and the exi...

This article describes a case of persistent apical periodontitis that required several nonsurgical and surgical approaches for resolution. A 28-year-old woman presented with a large symptomatic apical periodontitis lesion associated with the maxillary left lateral incisor that persisted in spite of previous nonsurgical and surgical endodontic treatment. Root canal retreatment was accomplished, ...

AIM To evaluate the solubility of five different root canal sealers (AH Plus Jet, RealSeal SE, MTA Fillapex, Tubli-Seal, and Acroseal) in chloroform, eucalyptol and Endosolv-E solvents. MATERIALS AND METHODS Ninety root canal sealer samples were prepared and then divided into three groups for immersion in a solvent for 2, 5 or 10 minutes. The mean values of the root canal sealers' dissolution...

This in vivo study investigated the time of degradation of root filling material (trans 1,4-polyisoprene) retrieved from endodontically treated teeth and correlated the occurrence of degradation with the longevity of endodontics. Thirty-six root-filled teeth with different filling times (2 to 30 years) and with and without periapical lesions were selected. All teeth presented clinical indicatio...

Background: This study aimed to compare the continuous rotation and reciprocating movements of rotary files in achieving apical patency root canal retreatment. Materials Methods: vitro, experimental evaluated 64 extracted mandibular molars. The teeth were prepared up F3 with ProTaper Universal obturated using lateral compaction technique. divided into four groups (n = 16) based on mesiobuccal c...
