Tsurumachi, M. Hayashi & O. TakeichiDepartment of Endodontics, Nihon University School of Dentistry, Tokyo, Japan Aim.To describe the clinical management of an unusual dens invaginatus type 2. Summary.A case of dens invaginatus in a maxillary lateral incisor with a periapical lesion is reported. The patient presented with pain and localized swelling. Despite the complex anatomy and diagnosis of dens invaginatus , non-surgical root canal treatment was performed successfully. Key learning points.• Dens invaginatus may be presented in many forms, and the aetiology of this phenomenon is not fully understood.• Due to abnormal anatomical configuration, dens invaginatus presents technical difficulties in its clinical management.• Non-surgical root canal treatment can be performed successfully. muveqqeti@gmail.com (JofER editor) Wed, 23 Jan 2002 00:00:00 -0600 http://endodonticsjournal.com/articles/10/1/Incidence-of-root-fractures-and-methods-used-for-post-removal/Page1.html P. V. AbbottSchool of Dental Science, University of Melbourne, Melbourne, Victoria, Australia Aim.This study was undertaken to determine the incidence of root fractures during post removal, as well as the methods used and the success rates achieved with various post removal devices and techniques. Conclusions.This study indicates that, with good case selection, post removal is a predictable procedure. If appropriate techniques and devices are used for the particular type of post being removed, then root fracture is a rare occurrence. muveqqeti@gmail.com (JofER editor) Tue, 22 Jan 2002 00:00:00 -0600 http://endodonticsjournal.com/articles/9/1/Root-and-canal-morphology-of-Thai-mandibular-molars/Page1.html K. Gulabivala, A. Opasanon, Y.-L. Ng & A. AlaviDepartment of Conservative Dentistry, Eastman Dental Institute for Oral Health Care Sciences, University College London, London, UK Aim.To investigate the root and canal morphology of 351 mandibular permanent molars collected from an indigenous Thai population. Conclusions.This study suggests that Thai molars exhibit features of both Caucasian and Chinese teeth. muveqqeti@gmail.com (JofER editor) Mon, 21 Jan 2002 00:00:00 -0600 http://endodonticsjournal.com/articles/8/1/In-vitro-cytotoxicity-of-a-composite-resin-and-compomer/Page1.html C. A. Quinlan, D. M. Zisterer, K. F. Tipton & M. I. O’SullivanDublin Dental HospitalDepartment of Biochemistry, Trinity College, Dublin, Ireland Aim.This work was designed to investigate the potential cytotoxicity of two of the newer dental restorative materials, Spectrum® composite resin and Dyract® AP compomer. Conclusions.These results indicate the restorative materials to be potentially toxic, particularly if the degree of light-cure is inadequate. muveqqeti@gmail.com (JofER editor) Sat, 19 Jan 2002 00:00:00 -0600 http://endodonticsjournal.com/articles/7/1/A-comparative-study-of-root-canal-preparation-using-ProFile-04-and-Lightspeed-rotary-NiaTi-instruments/Page1.html J. Versümer, M. Hülsmann & F. SchäfersDepartment of Operative Dentistry, University of Göttingen, Germany Aim.The purpose of this study was to compare several parameters of root canal preparation using two different rotary nickelâ€"titanium instruments: ProFile .04 (Dentsply/Maillefer, Ballaigues, Switzerland) and Lightspeed (Lightspeed Technology Inc., San Antonio, TX, USA). Conclusions.Both systems under investigation respected original root canal curvature and were safe to use. Both systems can be recommended for clinical use. muveqqeti@gmail.com (JofER editor) Fri, 18 Jan 2002 00:00:00 -0600 http://endodonticsjournal.com/articles/5/1/Occlusal-loading-of-EBA-and-MTA-root-end-fillings-in-a-computer-controlled-masticator-a-scanning-electron-microscopic-study/Page1.html C.I. Peters & O.A. PetersEndodontic Division, Department of Preventive Dentistry, Cariology and Periodontology, University of Zurich, Zurich, Switzerland Aim.The aim of this investigation was to assess the marginal adaptation of Super-EBA (EBA) and Pro Root MTA (MTA) root-end fillings and the occurrence of microcracks in resected root-ends of extracted teeth before and after occlusal loading for a five-year equivalent period in a computer-controlled masticator. Conclusions.Both EBA and MTA displayed excellent marginal adaptation before masticatory loading. After loading, the amount of continuous margin for both rootend filling materials decreased slightly but was still high. muveqqeti@gmail.com (JofER editor) Thu, 17 Jan 2002 00:00:00 -0600 http://endodonticsjournal.com/articles/6/1/Quantitative-analysis-of-substance-P-neurokinin-A-and-calcitonin-gene-related-peptide-in-pulp-tissue-from-painful-and-healthy-human-teeth/Page1.html L. Awawdeh, F. T. Lundy, C. Shaw, P-J. Lamey, G. J. Linden & J. G. KennedyFaculty of Dentistry, Jordan University of Science and Technology, Irbid, Jordan.School of Dentistry, The Queen’s University of Belfast, Belfast and School of Applied Biomedical Sciences, University of Ulster, Coleraine, UK. Aim.The purpose of this study was to investigate the levels of substance P (SP), neurokinin A (NKA) and calcitonin gene-related peptide (CGRP) in painful and healthy human dental pulps. Conclusions.Elevated levels of these neuropeptides in pulps from painful teeth indicate that they may play an important role in the process of pulpal inflammation and pain. Further investigation of the association between these neuropeptides and pulpal status may help to improve our understanding of pulpal inflammation and dental pain. muveqqeti@gmail.com (JofER editor) Wed, 16 Jan 2002 00:00:00 -0600 http://endodonticsjournal.com/articles/3/1/Effects-of-instrumentation-irrigation-and-dressing-with-calcium-hydroxide-on-infection-in-pulpless-teeth-with-periapical-bone-lesions/Page1.html L. B. Peters, A.-J. van Winkelhoff, J. F. Buijs& P. R. WesselinkDepartments of Cariology Endodontology Pedodontology, and Oral Microbiology, Academic Centre for Dentistry Amsterdam, Amsterdam, Netherlands Aim.The aim of this study was to evaluate the fate of microorganisms in root canals of teeth with infected pulps and periapical bone lesions with and without the use of calcium hydroxide medication. Conclusions.Although a calcium hydroxide paste was placed in the prepared canals, the number of positive canals had increased in the period between visits. However, the number of microorganisms had only increased to 0.93% of the original number of CFU (sample 1). It is concluded that a calcium hydroxide and sterile saline slurry limits but does not totally prevent regrowth of endodontic bacteria. muveqqeti@gmail.com (JofER editor) Mon, 14 Jan 2002 00:00:00 -0600 http://endodonticsjournal.com/articles/2/1/Influence-of-rotational-speed-torque-and-operator-proficiency-on-failure-of-Greater-Taper-files/Page1.html G. M. Yared, F. E. Bou Dagher, P. Machtou & G. K. KulkarniDiscipline of Endodontics and Preventive Dentistry, Faculty of Dentistry, University of Toronto, Canada.Department of Endodontics, Dental School, Lebanese University, Lebanon.Department of Endodontics, Dental School, University Paris 7-Denis Diderot, France. Aim.The purpose of this study was to evaluate the influence of rotational speed, torque, and operator experience on the incidence of locking, deformation, and separation of instruments when using a specific Niâ€"Ti rotary instrumentation technique in extracted human teeth. Conclusions.Preclinical training in the use of the GT rotary instruments when used with a crown-down technique at 150 r.p.m. was crucial in avoiding instrument separation and reducing the incidence of instrument locking and deformation. muveqqeti@gmail.com (JofER editor) Mon, 07 Jan 2002 00:00:00 -0600 http://endodonticsjournal.com/articles/1/1/A-protocol-for-polymerase-chain-reaction-detection-of-Enterococcus-faecalis-and-Enterococcus-faecium-from-the-root-canal/Page1.html Molander A, Lundquist P, Papapanou PN, Dahlen G, Reit C.Departments of Endodontology/Oral Diagnosis, Oral Biochemistry and Oral Microbiology, Faculty of Odontology, Göteborg University, Gothenburg, Sweden. Aim.The present study was set up to develop a protocol for detection of Enterococcus faecalis and Enterococcus faecium from the root canal. Conclusions.The present study demonstrated a good potential for using PCR technology in the detection of E. faecalis and E. faecium from root canal samples. With a high specificity the methodology was able to detect 10 cells of E. faecalis. muveqqeti@gmail.com (JofER editor) Tue, 01 Jan 2002 00:00:00 -0600
