Yu-Yao Teoh, Laurence J Walsh
This laboratory study assessed removability of endodontic alkaline cements and resin sealers using coronal cross-sectional slices of roots with single canals. Materials were labelled with 0.1% (w/w) sodium fluorescein prior to mixing so that confocal microscopy could be used to quantify material remaining on the walls of post spaces, to assess cleanliness. Roots of extracted teeth were prepared using rotary NiTi instruments then obturated using lateral condensation with gutta percha and epoxy resin sealers (AH-Plus™ or Zirmix™), or were filled by injecting mineral trioxide aggregate (MTA) cement (GC Nex™ MTA or MTAmix™) or a hard-setting calcium hydroxide cement (Supercal™)...

Successful root canal treatment requires management of the bacterial infection within the root canal space and protection of residual tooth structure with direct/indirect restorations. Long-term success depends upon prevention of re-infection of the root canal space as well as ensuring favourable distribution of the occlusal forces throughout the residual tooth structure. Appropriate planning and design of the final restoration prior to initiating root canal treatment is paramount in achieving this objective...

INTRODUCTION: Previous studies in patients with irreversible pulpitis have reported increased success of the inferior alveolar nerve block (IANB) using premedication with ketorolac. Preemptive nitrous oxide administration has also shown an increase in the success of the IANB. Recently, ketorolac has been made available for intranasal delivery. Perhaps combining ketorolac and nitrous oxide would increase success. Therefore, the purpose of this prospective, randomized, double-blind study was to determine the effect of a combination of intranasal ketorolac and nitrous oxide/oxygen on the anesthetic success of the IANB in patients presenting with symptomatic irreversible pulpitis...

Dilaceration is a rare disturbance in traumatised permanent teeth, which constitutes about 3% of the injuries to developing teeth. It usually occurs as a result of trauma to the deciduous predecessors and results in non axial displacement of the already formed hard tissue portion of the developing crown. Endodontic treatment of such teeth presents a challenge to clinicians, and careful management is required to successfully address the root canal anatomy and other possible variations. The C-shaped canal configuration is most frequently seen in mandibular second molars, but this variation may also occur in mandibular first molars, mandibular third molars, maxillary molars, mandibular first premolars, and even in maxillary lateral incisors, with rare reports of such variations occurring in the maxillary central incisors...

BACKGROUND: The quality of the coronal seal of root canal filling material is important for periapical health. Absorption of water or saliva by the temporary restorative materials leads to dimensional changes, loss of retention, staining and breaking in margin contours. Hence this study was carried out to evaluate and compare the sealing properties, water absorption and solubility of IRM (intermediate restorative material), Cavit G and GC Caviton. STUDY DESIGN: Experimental, in vitro intergroup randomized control trial...

Root canal configuration is an important subject in endodontic practice and dentists should be familiar with all possible types of root canal configuration. A forty-three year old male was referred for root canal treatment of his maxillary left second molar tooth with symptomatic irreversible pulpitis. Pre-operative radiographs showed a three rooted molar. However, after access cavity preparation two palatal and one buccal orifices were detected. The patient was informed of the unusual root canal anatomy and cone-beam computed tomography (CBCT) was ordered for precise evaluation of the anatomy...

Fractured endodontic instrument is an unfortunate endodontic mishap which may obstruct thorough cleaning and shaping of the root canals with potential impact on the endodontic prognosis and treatment outcome. When the fractured segment lies apical to canal curvature, overzealous removal of tooth structure is required to gain access to the separated segment which in turn increases the likelihood of root fracture. In infected cases, the stage at which instrument separation occurs is crucial as root canal disinfection is jeopardized...
