Comparison of Different Root Canal Disinfection Protocols for Bacterial Reduction in Teeth With Apical Periodontitis Using Two Analytical Microbiological Methods: a Randomized Clinical Study
State University of New York at Buffalo
Summary
Evaluate and compare the disinfecting efficacy of two supplementary antimicrobial protocols in teeth with apical periodontitis
Description
This study aims to evaluate and compare the disinfecting efficacy of two supplementary antimicrobial protocols in teeth with apical periodontitis: Er,Cr:YSGG laser activated irrigation and ultrasonic activation using a piezoelectric ultrasonic device (Dentsply International Inc., York, PA, USA) and Irrisafe tip (Satelec/Acteon, Merignac, France), comparing the detection of bacteria before and after instrumentation. Secondary aims are to assess presence of bacteria before and after chemomechanical preparation using two microbiological methods: * ATP level analysis using the Endocator device *…
