Abstract:
Pulp and periapical diseases originate from microbial colonization of root canals. The development of new technologies and instrumentation techniques has provided more effective shaping of the root canal system. Even so, sodium hypochlorite and calcium hydroxide remain examples of auxiliary substances for endodontic treatment. Recently, ozone has emerged as promising in endodontic therapy. This study evaluated the antimicrobial activity of ozonized water and ozonized oils in root canals infected with Enterococcus faecalis, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans, in

Abstract:
The use of ozone in dentistry was suggested because of its antimicrobial, disinfectant, biocompatibility and therapeutic properties. In the last decade, the number of therapeutic ozone fluids has been detected to present frequent dental infections associated with periodontal disease, endodontic treatments and cavities. Despite these advantages, ozone therapy in dentistry is limited due to possible side effects. Therefore, dentists should know about the proper use of ozone therapy that can provide better patient care and significantly reduce the time and costs of treatment. The ozone is success

Abstract Background: The persistent pathogenic microorganisms in root canal system even after chemo-mechanical preparations cause endodontic infection and failure of the treatment. Thus the filling material, in addition to its good sealing ability, should offer long term antimicrobial effect and be non-toxic to cells and dentin. Zinc Oxide Eugenol (ZOE) is the most commonly used root canal sealer in endodontics. Electron beam (e-beam) is an ionizing radiation and known to cause physiochemical and biological changes.

In this study, we sought to demonstrate the toxicity of different concentrations of ozonated water in zebrafish embryos up to 120 hours postfertilization (hpf ) and their antimicrobial activity advantages. For the test, we placed 40 embryos per treatment in Petri dishes containing 30 ml of solution to be tested. The ozone concentrations used were calculated from an initial concentration of 72 μg/ml using the O&L 1.5 RM ozone generator (Ozone & Life, Brazil). Five serial dilutions 1:1 was performed in egg water to produce the ozone treatments. We also analyzed a treatment with 30 ml of

Abstract:
Background: The success of endodontic treatment depends on the complete debridement and disinfection of canal space. Various chemicals have been used for canal disinfection. However, to overcome the adverse effects, toxicity issues, and microbial resistance of most conventional canal disinfectants, alternative agents are needed. Many herbal products have been studied and recommended for canal disinfection. This article aimed to review the role of herbal extracts in canal disinfection as an irrigant, intracanal medicament, and their efficacy in smear layer removal.

However, with the increasing prevalence of antibiotic resistance and the need for new ideas in therapy, adjunctive treatments like ozone therapy have gained attention.

The search for a wide spectrum of antimicrobial agents that can avoid resistance while maintaining reasonable side effects has led to ozonated oils experiencing an increase in scientific interest and clinical applications.
