Continuous Chelation Concept in Endodontics

Background:Continuous chelation can be defined as the concept of using a single mix weak chelator with NaOCL throughout entire root canal preparation procedure without causing reduction in antimicrobial and proteolytic activity NaOCL. Etidronic acid, also known "1-Hydroxyethylidene-1, 1-Bisphosphonate" HEBP, or HEDP, is soft biocompatible utilized direct combination sodium hypochlorite to form an all-in-one deproteinizing, disinfecting, chelating solution. It's only available certified commercial product, "Dual Rinse HEDP," approved for endodontic usage. This review aims analyze bring up-to-date data about continuous protocol HEDP irrigation. Data: papers that were published electronically searched within review. Sources: “Google Scholar”,” PubMed” websites used searching by following keywords: : Bisphosphonates, Continuous chelation, Dual rinse Etidronate, HEBP. The most relevant related topic chosen, specifically original articles clinical studies, including English-language from 2005 September 2022. Conclusion:Combining solution, irrigation solution mixture tissue dissolving ability antibacterial properties capability created, which considered good alternative conventional (sequential irrigation) followed strong such EDTA. obvious benefit one required cleansing decontamination, decreasing time providing better conditioning walls root-filling materials
