Available in PDF, EPUB and Kindle. Book excerpt: This book covers knowledge of recent root canal sealers used in dentistry in a simplified manner. Properties of sealers, their effect on culture cells depicting their cytotoxicity level in a timely fashion. sealers were tested in vitro to simulate the conditions in vivo. Biological compatibility of root canal sealers is of importance as these materials frequently come into contact with periapical tissues. The tissue response to these materials may influence the final outcome of the root canal treatment. A sealer should not hinder tissue repair, but aid or stimulate the reorganization of injured structures. Various researches and studies have been done previously to test the biocompatibility of different material classes and products of root canal sealers. The results of these studies varies considerably depending upon the methods employed and other factors affecting the efficacy of test. The study, "Comparative evaluation of cytotoxicity profile of different root canal sealers: An in vitro analysis" was conducted in the Department of Conservative Dentistry and Endodontics, King George's Medical University, Lucknow in collaboration with Central Drug and Research Institute, Lucknow.

Download or read book Endodontic Sealers An Overview written by Neha Saini and published by LAP Lambert Academic Publishing. This book was released on 2014-07-23 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The endodontic triad; consisting of biomechanical preparation, microbial control and complete obturation of the canal space; remains the basis of endodontic therapy. Complete obturation of pulp space as efficiently and three dimensionally as possible is considered to be an important part of root canal treatment. Endodontic literature reports the need to seal the root canal in a hermetic way i.e. the canal system should be sealed apically, coronally and laterally. Leonardo and Leal (1991) affirmed that to seal a root canal means to fill it in all its extension with an inert, antiseptic material, obtaining the most hermetic seal possible. Various endodontic materials have been advocated for obturation of the radicular space. Most techniques employ a core material and a sealer. All core materials require a sealer. There are no exceptions to this rule. Although there are a large number of filling materials, the combination of gutta-percha and a sealer is most widely used in clinical practice. The purpose of sealing root canals is to prevent periapical exudates from diffusing into the unfilled part of the canal, to prevent re-entry and colonization of bacteria .

Download or read book Root End Resection Retro Preparation and Retrograde Root End Filling Materials written by Dr Pooja Phabyani and published by GRIN Verlag. This book was released on 2019-11-11 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2016 in the subject Medicine - Dentistry, grade: A, , course: MDS, language: English, abstract: This book analyses different types of retrograde filling materials. The major goals of root canal treatment are to clean and shape the root canal system and seal it in 3 dimensions to prevent reinfection of the tooth. Although initial root canal therapy has high degree of success, failures can still occur after treatment. Recent studies reported failure rates of 14%–16% for initial root canal treatment. Lack of healing is attributed to persistent intraradicular infection residing in previously uninstrumented canals, dentinal tubules, or in the complex irregularities of the root canal system. The extraradicular causes of endodontic failures include periapical actinomycosis, a foreign body reaction caused by extruded endodontic materials, an accumulation of endogenous cholesterol crystals in the apical tissues, and an unresolved cystic lesion. This book is composed of ten chapters and begins with the need of root-end resection. The succeeding chapters deal with the method and concept of root-end resection, root end preparation to receive the material, ideal requirements of materials to be placed in the resected and prepared root-end. The concluding chapters describe various root-end materials available in the market so far and their properties, focusing on each individual material one by one, their advantages and disadvantages. This book will prove useful to Endodontists and Researchers in the field of endodontic surgeries & root-end filling materials. Also it would provide the undergraduate and postgraduate students an easy way of reference for covering a broad spectrum of Root-end filling Materials available today, in lucid and simple language.

Download or read book Root Canal Sealers written by Preeti Mishra and published by LAP Lambert Academic Publishing. This book was released on 2015-11-12 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sealer is to fill the gaps between the core material and the walls of the root canal. A hermetic seal cannot be obtained without the use of a sealer which forms a fluid tight seal and barrier between the dentin and core material apically, laterally and coronally. All sealers are required to possess certain physical and biological properties. These properties include biocompatibility, strength, sealing ability, adequate working and setting time, flow, solubility and various other characteristics. However, no sealer has been shown to be totally satisfactory for clinical use.

This book was released on 2013 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main problems of dentists and endodontic for treatment of teeth in need for root canal therapy is the lack of perfect seal at the apical area to meet their requirements. The sealing properties of root canal filling materials is one of the most important factor that can influence apical seal. When filling the root canal system, the sealer plays an important role in reducing microleakage . A great variety of endodontic sealers are available commercially, and they are divided into groups according to their chemical composition such as zinc oxide eugenol sealers, epoxy resin sealers, and calcium hydroxide sealers. The aim of this research is to present an investigation regarding the in vitro comparison of apical leakage of RSA ( Roekoseal Automix ) and Roth 801 and AH26 sealers in lateral condensation technique using dye leakage method using new method for the leakage measurement.

This book was released on 2011 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: New sealers have been placed on the market to improve the property of a hermetic seal within the root canal and decrease the gap between the gutta-percha and dentin wall. Differences in the adhesive properties of endodontic sealers may be expected because their interaction with either dentin or gutta-percha may vary with their chemical composition. No specific interaction either with dentin or gutta-percha is expected from the setting reaction of calcium hydroxide based sealers and the epoxy-based sealers. The setting reaction of the zinc oxide-eugenol mixtures is a chelation reaction occurring with the zinc ion of the zinc oxide. Development and maintenance of the seal are essential to optimize the long-term success rate of root canal treatment. An ideal endodontic sealer should, in part, adhere firmly both to dentin and gutta-percha. PURPOSE: The purpose of this study is to evaluate the sealing properties of EndoSequence BC sealer TM, a bioceramic sealer, and Roth's sealer using gutta-percha with warm vertical condensation and using the single cone technique with the EndoSequence BC sealer only. The goal is to see if there is a significant difference in microleakage between teeth sealed with the bioceramic sealer and teeth sealed with Roth's sealer. MATERIALS & METHODS: Eighty-five single-rooted maxillary anterior teeth were used for this study. Endodontic cleaning and shaping of each root canal system was accomplished using K-type hand files and NiTi Rotary files. Group A consisted of twenty-seven anterior teeth, which were obturated using EndoSequence BC sealer and gutta-percha with System B and Obtura. Another twenty-seven anterior teeth, Group B, was obturated using Roth's sealer and gutta-percha with System B and Obtura. A final group, Group C with 27 teeth was obturated using the single cone technique by means of a single gutta-percha point with Endosequence BC sealer. Two teeth were used as a positive control group, and two other teeth as a negative control group. A microbial leakage apparatus was constructed using a similar two-chamber method described by Torabinejad et al. E. faecalis ATCC 29212 was the test bacteria which was used in this study to determine microleakage The outcome of interest (bacterial turbidity) and time-to-leakage (in days), will be determined for each of the samples. Survival analysis will be used to compare the two groups, with a Kaplan-Meier plot to visualize the results and a nonparametric log-rank test for the group comparison RESULTS: No microleakage was observed in the negative control or group B. Microleakage was observed in all the positive control. Group A and C had a significantly higher proportion of samples with microleakage than group B (p

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Endodontic sealers are intended to entomb residual bacteria and prevent reinfection of the root canal system. However, current endodontic sealers either have no antimicrobial properties or lose their antimicrobial activity after setting. Objective: To assess the effect of incorporating a novel highly-loaded antimicrobial drug-silica co-assembled particles (DSPs) on the flow and antimicrobial properties of root canal sealers. Materials: DSPs were mixed homogenously with either epoxy-resin sealer or calcium silicate-based sealer. The sealers' antimicrobial activity against planktonic and biofilms of Enteroccocus faecalis ATCC 47077 infected dentin was investigated using in vitro tooth model. Results: DSPs had no effect on the antimicrobial properties of epoxy-resin sealer; however, it improved the antimicrobial performance of calcium silicate-based sealer throughout the 30-day experiments while maintaining the flow compliant with the ISO parameters. Conclusion: Depending on the sealer, DSPs could potentially prevent interfacial biofilm formation and proliferation, potentially decreasing the risk of persistent/secondary endodontic infections.
