E. Murray, A. J. Smith, L. J. Windsor & I. A. MjorOral Biology, Indiana University School of Dentistry, Indianapolis, IN, USA.Oral Biology, School of Dentistry, The University of Birmingham, Birmingham, UK.NIOM, Scandinavian Institute of Dental Materials, Oslo, Norway.College of Dentistry, University of Florida, Gainesville, FL, USA.Aim.To evaluate pulp responses as a function of remaining dentine thickness (RDT) of 98 class V cavity preparations in 49 teeth of 31 patients aged 10-16 years. Conclusions.Cavity RDT mediates a powerful influence on underlying pulp tissue vitality but it has little effect on reactionary dentine secretion and inflammatory activity. Gross tissue injury explains the poor pulp capping prognosis following exposure and underlies the need to avoid this type of injury. Following restoration, a RDT of 0.5 mm or greater is necessary to avoid evidence of pulp injury. muveqqeti@gmail.com (JofER editor) Thu, 25 Dec 2008 00:00:00 -0600 http://endodonticsjournal.com/articles/133/1/Radiographic-features-and-outcome-of-root-canal-treatment-carried-out-in-the-Lodz-region-of-Poland/Page1.html E. Boltacz-Rzepkowska & H. Pawlicka Department of Conservative Dentistry, Institute of Dentistry, Medical University of Lodz, Poland.  Aim.The aim of this study was to assess the radiographic features and factors affecting the long-term results of root canal treatment in the Lodz region of Poland. Conclusion.The radiographic technical quality of the root canal treatment was associated with the outcome that root fillings of adequate standard were associated with health more often than inadequate root fillings. Pulpotomy was associated with periapical disease in the majority of cases. muveqqeti@gmail.com (JofER editor) Tue, 23 Dec 2008 00:00:00 -0600 http://endodonticsjournal.com/articles/132/1/Oral-treponemes-in-primary-root-canal-infections-as-detected-by-nested-PCR/Page1.html I. N. Rocas, J. F. Siqueira Jr, A. F. B. Andrade &M. UzedaDepartment of Endodontics, Faculty of Dentistry, Estacio de Sa UniversityDepartment of Microbiology, State University of Rio de Janeiro, and Institute of Microbiology, Federal University of Rio de Janeiro, Rio de Janeiro, RJ, Brazil.Aim.To investigate the prevalences of four Treponema species in primary root canal infections using a nested PCR assay. Conclusions.The species T. denticola was detected in a large number of the cases examined; the prevalence of T. socranskii was also relatively high. The species T. vincentii and T. pectinovorum were also found, but in a smaller number of cases. Based on these data, the recognized pathogenicity of these microorganisms and their involvement with other oral diseases, they should be included in the restricted set of putative endodontic pathogens. muveqqeti@gmail.com (JofER editor) Thu, 18 Dec 2008 00:00:00 -0600 http://endodonticsjournal.com/articles/131/1/Effect-of-X-ray-beam-angulation-and-intraradicular-contrast-medium-on-radiographic-interpretation-of-lower-first-molar-root-canal-anatomy/Page1.html H. J. Naoum, R. M. Love, N. P. Chandler & P. HerbisonDepartments of Oral Rehabilitation, Stomatology, Preventive and Social Medicine, University of Otago, Dunedin, New Zealand.Aims.To compare evaluator radiographic interpretation of noncontrasted and contrasted root canal anatomy on radiographs taken at a 0 or 308 mesial angle to the orthoradial orientation. Conclusions.Under the conditions of this study, conventional radiographs taken at a 08 orientation provided more information than 308 radiographs. Contrast medium improved radiographic interpretation of canal anatomy, especially when used with 308 radiographs. muveqqeti@gmail.com (JofER editor) Thu, 18 Dec 2008 00:00:00 -0600 http://endodonticsjournal.com/articles/130/1/Biocompatibility-of-dental-materials-used-in-contemporary-endodontic-therapy-a-review-Part-1-Intracanal-drugs-and-substances/Page1.html C. H. J. Hauman & R. M. LoveDepartments of Oral Rehabilitation, and 2Stomatology, School of Dentistry, University of Otago, Dunedin, New Zealand.Irrigation solutions and intracanal medicaments are used within the root canal to clean and aid in disinfecting the dentinal walls. Although these materials are intended to be contained within the root canal, they invariably contact the periapical tissues, either through inadvertent extrusion through the apex or leaching. This paper is a review on the methodology involved in biocompatibility testing followed by a discussion on biocompatibility of contemporary intracanal drugs and substances used in endodontics. muveqqeti@gmail.com (JofER editor) Mon, 15 Dec 2008 00:00:00 -0600 http://endodonticsjournal.com/articles/129/1/Microorganisms-from-canals-of-root-filled-teeth-with-periapical-lesions/Page1.html E.T. Pinheiro, B. P. F. A. Gomes, C. C. R. Ferraz, E. L. R. Sousa, F. B.Teixeira & F. J. Souza-Filho Endodontic Department, Piracicaba Dental School, State University of Campinas, UNICAMP, Piracicaba, SP, Brazil.Aim.The objective of the present study was to identify the microbial flora within root canals of teeth with failed root-canal treatment and to determine the association of the various species with clinical features. Conclusion.The microbial flora in canals after failure of root-canal treatment were limited to a small number of predominantly gram-positive microbial species. Facultative anaerobes, especially E. faecalis, were the most commonly isolated microorganisms, however, polymicrobial infections and obligate anaerobes were frequently found in canals of symptomatic root-filled teeth. muveqqeti@gmail.com (JofER editor) Wed, 10 Dec 2008 00:00:00 -0600 http://endodonticsjournal.com/articles/128/1/Prodromal-herpes-zoster-a-a-diagnostic-challenge-in-endodontics/Page1.html I. Fristad, A. Brdsen, G. C. Knudsen & O. Molven Department of Odontology â€" Endodontics, School of Dentistry, University of Bergen, Bergen, Norway.Key learning points.A long lasting prodromal stage is an unusual event. Symptoms combined with inadequate technical standard of root fillings may confuse the diagnostics. No available data support or suggest the use of antiviral treatment as a diagnostic tool. muveqqeti@gmail.com (JofER editor) Fri, 05 Dec 2008 00:00:00 -0600 http://endodonticsjournal.com/articles/127/1/A-comparative-study-of-lateral-condensation-heat-softened-gutta-percha-and-a-modified-master-cone-heat-softened-backfilling-technique/Page1.html D. Da Silva, U. Endal, A. Reynaud, I. Portenier, D. Orstavik & M. HaapasaloDepartment of Endodontics, Dental Faculty, University of Oslo, Oslo.NIOM, Scandinavian Institute of Dental Materials, Haslum, Norway.Aim.The aim of the study was to compare the quality of root fillings completed by lateral condensation (LC), Thermafil (TF), and a new technique using Thermafil for backfilling (BF), with special emphasis on control of overfilling. Conclusions.LC and BF techniques resulted in fewer overfills than TF. Voids were absent in TF fillings, whilst small voids were found in the LC and BF groups. muveqqeti@gmail.com (JofER editor) Fri, 05 Dec 2008 00:00:00 -0600 http://endodonticsjournal.com/articles/126/1/Location-arrangement-and-possible-function-of-interodontoblastic-collagen-fibres-in-association-with-calcium-hydroxide-induced-hard-tissue-bridges/Page1.html Y. Kitasako, S. Shibata, C. F. Cox & J. TagamiCariology and Operative Dentistry, Department of Restorative Sciences and Maxilofacial Anatomy, Department of Maxillofacial/ Neck Reconstruction Maxillofacial Biology, Graduate School, Tokyo Medical and Dental University, Tokyo, Japan.Departments of Restorative Dentistry and Biomaterials, University of Alabama, Birmingham, AL, USA.Aim.To assess the location, arrangement and possible function of interodontoblastic collagen fibres in association with calcium hydroxide-induced hard tissue bridges by using light and transmission electron microscopy techniques and immunohistochemical staining localization. Conclusions.Interodontoblastic collagen fibres were routinely detected throughout early dentine bridges. Interodontoblastic collagen fibres are thought to be important for initial dentine bridging to induce and support a dentinogenesis framework. muveqqeti@gmail.com (JofER editor) Wed, 03 Dec 2008 00:00:00 -0600 http://endodonticsjournal.com/articles/125/1/Indirect-digital-images-limit-of-image-compression-for-diagnosis-in-endodontics/Page1.html M. Siragusa & D. J. McDonnell Department of Endodontics, School of Dentistry, Universidad Nacional de Rosario, Santa Fe, Rosario, Argentina.Aim.To analyze the impact of the loss of information that results from the compression of a file containing a radiographic image. Conclusions.The compression ratio calculated as the quotient between the file sizes and the standard deviation of the values corresponding to the image that resulted from digital subtraction may be employed to assess the outcome of the compression process and guarantee adequate quality. muveqqeti@gmail.com (JofER editor) Wed, 03 Dec 2008 00:00:00 -0600
