It’s A Tale of Two Hygienists’ monthly student roundtable episode, which means Andrew and Michelle have invited a quartet of guests to educate student listeners on a chosen topic. Today’s topic is subgingival irrigation, a form of hydrotherapy used to prevent further deterioration of tooth structure.   Spring Hatfield is a dental hygienist and co-founder of Dental Masterminds, LLC, which offers study clubs and CE courses for dental professionals. Spring’s work focuses on the connection between oral and systemic disease. Daniel Lopez is a hygienist with Access Community Health Center in Manhattan who works with patients affected by HIV.   In this episode, our guests introduce, summarize and discuss the studies they’ve brought to the table, explain why ozone application needs to be “just right,” and examine the bias where a journal’s country of origin can unconsciously affect how seriously we take it.     EPISODE HIGHLIGHTS:   Interview starts: 4:03   - Spring summarizes the findings of a study on ozone-infused waters and oils used in subgingival irrigation.   - Explaining “the Goldilocks principle” and how ozone relates to it.   - What is a “free radical” and why should hygienists be concerned about them?   - Daniel discusses a study that makes the case for using 10% povidone-iodine during irrigation.   - Why it’s vital to overcome one’s bias toward certain journals based on their country of origin.   - Debating the merits of doing a pre-procedural rinse.       QUOTES:   “We do kinda graduate thinking that only our research is relevant.”   “Homecare is where it’s at, period.”   “That rinse with an alcohol-based mouthwash really helps decrease that blood flow.”   “See what is available to you, see what’s out there, for those patients you otherwise just can’t help.”   LINKS:   Daniel's email: lopez.j.daniel@gmail.com    Spring’s email: springhatfieldrdh@gmail.com    “Effect of Subgingival Application of Topical Ozonated Olive Oil…” - https://pubmed.ncbi.nlm.nih.gov/22976566/    “Efficacy of subgingival irrigation with 10% povidone-iodine...” - http://www.ijdr.in/article.asp?issn=0970-9290;year=2017;volume=28;issue=5;spage=514;epage=518;aulast=Sindhura THIS EPISODE COUNTS FOR CE! - but read the disclaimer below as it might not count for your state.
