Fracture Necrosis: Diagnosis, Prognosis Assessment, and Treatment Recommendations

Journal of Endodontics — Fri, 19 Feb 2010 14:02:33 +0100

Conclusion: Pulp necrosis, in the absence of restorations, caries, or luxation injuries, is likely caused by a longitudinal fracture extending from the occlusal surface and into the pulp. Based on the available literature, these types of teeth may have a poor prognosis after endodontic treatment, with the potential ramification of extensive periodontal and/or periapical bone loss. Extraction may be considered as the primary treatment option. (Source: Journal of Endodontics)

Anesthetic Efficacy of Articaine and Lidocaine for Incisive/Mental Nerve Block

Journal of Endodontics — Fri, 19 Feb 2010 14:02:33 +0100

Conclusions: Articaine promoted higher anesthesia success and longer duration of anesthesia than lidocaine for most of the teeth after IMNB although anesthesia success could be considered clinically appropriated only for premolars. The volume of local anesthetic used in the present study may not be appropriate for procedures lasting longer than 10 minutes. (Source: Journal of Endodontics)

Comparison of Organic Tissue Dissolution Capacities of Sodium Hypochlorite and Chlorine Dioxide

Journal of Endodontics — Thu, 28 Jan 2010 14:09:59 +0100

In this study, 5.25% NaOCl, 13.8% ClO2, and, as a control, isotonic saline solutions (0.9% NaCl) were used. Thirty bovine pulp specimens were previously weighed and immersed for 20 minutes in each test solution (changing the solution every 2 minutes). The pulp specimens were then blotted dry and weighed again. The percentage of weight loss was calculated and statistically analyzed by using one-way analysis of variance and post hoc Tukey honestly significant difference tests. Saline solution did not dissolve the organic tissue. Both 5.25% NaOCl and 13.8% ClO2 dissolved the tissue pieces more effectively than saline control (P < .05). No statistically significant difference was found between the tissue-dissolving properties of 5.25% NaOCl and those of 13.8% ClO2 (P > .05). Within the limita...

Effect of MTAD on the Differentiation of Osteoblast-like Cells

Journal of Endodontics — Thu, 28 Jan 2010 14:09:58 +0100

Conclusions: These results suggested that MTAD is a less cytotoxic irrigant and does not affect differentiation into osteoblasts compared with other intracanal irrigants, such as H2O2, NaOCl, ethylenediaminetetraacetic acid, and chlorhexidine. (Source: Journal of Endodontics)

Effect of Proinflammatory Cytokines on the Expression and Regulation of Human Beta-Defensin 2 in Human Dental Pulp Cells

Journal of Endodontics — Thu, 10 Dec 2009 13:57:30 +0100

Conclusion: These results suggest that TNF-α and IL-1α up-regulate HBD-2 expression in HDP cells through the PKC, JNK MAPK, p38, ERK, NF-κB, and AMPK pathways. Thus, the induction of hBD-2 by proinflammatory cytokines might up-regulate the pulpal host immune defense system. (Source: Journal of Endodontics)

Identification of Bacteria Enduring Endodontic Treatment Procedures by a Combined Reverse Transcriptase–Polymerase Chain Reaction and Reverse-Capture Checkerboard Approach

Journal of Endodontics — Thu, 10 Dec 2009 13:57:29 +0100

Conclusions: The present study with a combined molecular approach revealed that bacterial diversity was overall markedly reduced by treatment procedures. Although bacterial taxa more frequently identified in post-treatment samples emerge as potential risk factors for persistent disease, this remains to be determined by longitudinal studies.

Fate of the Tissue in Lateral Canals and Apical Ramifications in Response to Pathologic Conditions and Treatment Procedures

Journal of Endodontics — Thu, 10 Dec 2009 13:57:28 +0100

Conclusions: Overall, the belief that lateral canals must be injected with filling material to enhance treatment outcome was not supported by literature review or by our histopathologic observations. It appears that strategies other than finding a technique that better squeezes sealer or gutta-percha within LC/AR should be pursued to effectively disinfect these regions.

Challenges in Regenerative Endodontics: A Case Series

Journal of Endodontics — Mon, 07 Dec 2009 00:00:00 +0100

Conclusions: Results from this case series show that revascularization is a technically challenging but effective treatment modality for the immature tooth with apical periodontitis. Based on this case series, the following recommendations are made to help with the revascularization technique: (1) clinicians should consider the use of an anesthetic without a vasoconstrictor when trying to induce bleeding, (2) a collagen matrix is useful for the controlled placement of MTA to a desired and optimal level, (3) patients/parents should be informed about the potential for staining, especially in anterior teeth when the paste contains minocycline, and (4) patient/parent compliance with the necessary multiple appointment treatment plan may be significant for case selection.

Photodynamic Therapy with Two Different Photosensitizers as a Supplement to Instrumentation/Irrigation Procedures in Promoting Intracanal Reduction of Enterococcus faecalis

Journal of Endodontics — Mon, 07 Dec 2009 00:00:00 +0100

Conclusion: These in vitro results suggest that PDT with either MB or TB may not exert a significant supplemental effect to instrumentation/irrigation procedures with regard to intracanal disinfection. Further adjustments in the PDT protocol may be required to enhance predictability in bacterial elimination before clinical use is recommended. (Source: Journal of Endodontics)

High-throughput Gene and Protein Expression Analysis in Pulp Biologic Research: Review

Journal of Endodontics — Mon, 07 Dec 2009 00:00:00 +0100

Conclusions: Even though the adoption of the high-throughput transcriptomic and proteomic techniques in pulp biology has been fairly slow, their use is increasing and will significantly increase the understanding of pulp tissue physiology and pathology. The comprehensive data of the transcriptome and proteome of the pulp tissue and the odontoblasts will facilitate the understanding of their functions during health and disease and provide novel target molecules for diagnosis and treatment. Identification of the genes controlling odontoblast differentiation might lead to development of methods enabling induction of reparative dentin formation under carious lesions. Identification of the genes active during dentinogenesis might lead to recognition of regulatory factors, which would cause seco...

Identify and Determine the Metrics, Hierarchy, and Predictive Value of All the Parameters and/or Methods Used During Endodontic Diagnosis

Journal of Endodontics — Tue, 24 Nov 2009 14:05:45 +0100

Abstract: A Consensus Conference on Terminology was convened by the American Association of Endodontists in Chicago on Oct 3, 2008 to review solicited papers on focused questions. This paper addressed the question: Identify and determine the metrics, hierarchy, and predictive value of all the parameters and/or methods used during endodontic diagnosis. The best available clinical evidence was used to determine the sensitivity, specificity, and predictive value of pulpal and periapical testing methods and imaging technologies. Diagnosis of dental pulp diseases suffers from operator's inability to test/image that tissue directly due to its location within dentin. In general, current pulp tests are more valid in determining teeth that are free of disease, but less effective in identifying tee...

Diagnostic Terminology: Report of an Online Survey

Journal of Endodontics — Tue, 24 Nov 2009 14:05:44 +0100

Conclusions: Data from the online survey provided trends and preferences toward particular diagnostic terms and beliefs. The limitations of such a survey are multiple including the limited size and nature of the respondent group, responses based on opinion, and question design. The online survey results suggest an awareness for the specialty to develop better diagnostic tools and terminology that are biologically and metric based. (Source: Journal of Endodontics)

AAE Consensus Conference on Diagnostic Terminology: Background and Perspectives

Journal of Endodontics — Tue, 24 Nov 2009 14:05:44 +0100

Diagnostic terminology in endodontics has been a topic of discussion, controversy, and debate for decades. Confusion in terminology naturally arises when educators, clinicians, and researchers use a wide array of diagnostic diction and schematics; when there are distinct differences in definitions of terms; when key endodontic textbooks promulgate histologically based characterizations for clinically based diagnoses; and when there are strong proponents of specific classification systems. Reasons for these disparities are myriad and multifactorial because diagnosis is already, in its own right, a complex and challenging process. Furthermore, there is a lack of biologically based terms that can represent the true status of the pulp and periapical tissues, poor correlations exist between cli...

Evaluation of Antimicrobial Efficacy of Herbal Alternatives (Triphala and Green Tea Polyphenols), MTAD, and 5% Sodium Hypochlorite against Enterococcus faecalis Biofilm Formed on Tooth Substrate: An In Vitro Study

Journal of Endodontics — Mon, 16 Nov 2009 00:00:00 +0100

Conclusions: 5% sodium hypochlorite showed maximum antibacterial activity against E. Faecalis biofilm formed on tooth substrate. Triphala, green tea polyphenols and MTAD showed statistically significant antibacterial activity. The use of herbal alternatives as a root canal irrigant might prove to be advantageous considering the several undesirable characteristics of NaOCl. (Source: Journal of Endodontics)

Effect of Various Chemicals as Solvents on the Dissolution of Set White Mineral Trioxide Aggregate: An In Vitro Study

Journal of Endodontics — Wed, 11 Nov 2009 00:00:00 +0100

Conclusions: Carbonic acid can be effectively used as an adjunct to dissolve set WMTA even after 21 days, whereas 2% chlorhexidine gluconate showed significant surface dissolution only within 24 hours of WMTA placement. Thus, usage of chlorhexidine gluconate as a root canal irrigant in which WMTA is used during endodontic procedure should be avoided for 24 hours. Solutions with EDTA have no effect on surface hardness of WMTA. (Source: Journal of Endodontics)
