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.

The first section of this book deals with microbiologic and pathophysiologic aspects of the different manifestations of apical periodontitis, while the second section describes the best evidence for predictable treatment and prevention of the disease. Clinical techniques and protocols to treat endodontic infections are described in detail. This new edition boasts a team of renowned authorities in the field that contribute state-of-the-art evidence about the biology and practice of the endodontic treatment of teeth with infected root canals. The content is supplemented with numerous full-color illustrations and radiographs. This book is a definitive guide to those involved with the prevention and treatment of endodontic infections.
Download or read book Dental Adhesive Systems Loaded with Antimicrobial Drug silica Co assembled Particles for Interfacial Biodegradation and Recurrent Caries Reduction written by Kimberly Ngai and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resin composite restorations fail prematurely mainly due to biodegradation and bacterial attack, leading to recurrent caries. It is hypothesized that 1) dental adhesives containing drug-silica-co-assembled-particles (DSPs) inhibit interfacial bacterial-biodegradation-markers (BBMs) and reduce interfacial demineralization and cavitation; 2) photothermal radiometry and luminescence (PTR-LUM) technology correlates positively with micro-computed-tomography (μCT) in recurrent caries detection. In vitro models based on simulated human salivary esterases and cariogenic bacteria to evaluate the effects of DSPs on interfacial biodegradation and recurrent caries development show long-term reduction in BBMs and interfacial demineralization and cavitation, suggesting that DSP-loaded dental adhesives are efficacious in reducing interfacial biodegradation and recurrent caries. PTR-LUM technology (the Canary System Numbers), was positively correlated to demineralization and cavitation measurements by μCT. Provision of antimicrobial-antidegradative properties to dental adhesives is a promising strategy to improve the longevity of resin composite restorations. Additionally, PTR-LUM technology may aid dental professionals in detecting recurrent caries, without radiation exposure.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: The primary reason for endodontic treatment failure is microbial infection inside the root canal system by different microbes including Enterococcus faecalis. Endodontic sealers with Chitosan (CS), a compound with antimicrobial effects, can decrease the growth of microorganisms and potentially prevent failure. Purpose: The aim of this study was to assess the antimicrobial activity ex-vivo and flowability of calcium silicate root canal sealers with added CS fillers. Materials and methods: EndoSequence (BC) sealer was mixed with CS fillers in two different concentrations (5% and 10%wt). Flowability was analyzed according to ISO-6876. The antibacterial assessment was conducted using an ex-vivo model. Extracted single-rooted teeth were infected with E. faecalis for 7 days. Follow the root canal treatment, the sealers (BC, BC+CS-5%, BC+CS-10%, N=6) were used for obturation and re-incubated in the bioreactor for 24 hours. Untreated teeth were used as positive control. Cell viability (CFU/mL) and fluorescence microscopy were used to determine the number of bacteria at the bonded interface. ANOVA was used for statistical analysis. Results: Addition of CS fillers into BC resulted in a significant decrease in flowability (BC:22mm, BC+CS-5%:19mm, BC+CS-10%:16mm). All evaluated sealers showed antibacterial activity. The addition of CS significantly reduced the viable cells (log(CFU/mL)) (CS-5%:5.3, CS-10%:4.6) compared with the BC (5.9) and positive control (7.2). Fluorescence analysis showed that CS-Sealers group had an increased number of dead cells (CS-10%:77.3%, CS-5%:64.4%) compared with the BC-Sealer (37.9%) and positive control (23.3%). Conclusion: Endodontic sealers with added CS enhanced antimicrobial effects of the sealer. However, adding more than 5% of CS affects the flow properties of the sealer.

Available in PDF, EPUB and Kindle. Book excerpt: Mineral trioxide aggregate (MTA) was developed more than 20 years ago to seal the pathways of communication of the root canal system. It’s currently the preferred material used by endodontists because of its superior properties such as its seal and biocompatibility that significantly improves outcomes of endodontic treatments. Dr. Torabinejad, who was the principle investigator of the dental applications of MTA, and leading authorities on this subject provide a clinically focused reference detailing the properties and uses of MTA, including vital pulp therapy (pulp capping, pulpotomy), apexification, pulp regeneration, repair of root perforations, root end filling and root canal filling. Line illustrations and clinical photographs show proper technique. An accompanying website features photographs and video presentations for selected procedures using MTA. Mineral Trioxide Aggregate: Properties and Clinical Applications is an ideal book for dental students and endodontic residents learning procedures for the first time as well as practicing dentists and endodontists who would like to improve outcomes of endodontic treatments.

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.

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.
