The History of RDA and Modern Erosive Tooth Wear
January 10 @ 7:30 pm – 9:00 pm EST
Free
1.5 CE credits
Overview: Patients are often fixated on the idea of toothpaste abrasiveness as the key factor in tooth wear; however, this talk will demonstrate that acid-mediated tooth wear, so-called erosive tooth wear, is the dominant process for tooth loss in typical individuals. This talk will also focus on how to reduce your risk of erosive tooth wear.
Objectives:
- Establish the history of RDA and abrasion measurements
- Demonstrate the clinical irrelevance of RDA values less than 250
- Consider lifetime dentin and enamel wear amounts based on RDA and clinical studies
- Illustrate the impact of acid on tooth wear and its amplification of tooth loss
- Discuss strategies to reduce the risk of erosive tooth wear
