Magister Scientiae Dentium - MSc(Dent)Introduction: The evolution of Dentistry witnessed an increase in fixed prostheses as
opposed to removable ones. Zirconia (ZrO2) and Lithium disilicate (LDS) are
becoming the material of choice in implant or tooth retained prostheses.
Polyetheretherketone (PEEK) is a recent alternative as it is lighter and causes less
wear of opposing retained teeth. Biofilm formation is a permanent daily struggle for
patients as it can be found in nearly all surfaces exposed to the natural environment.
Therefore, the interest in a new device capable of removing or reducing oral biofilm
from fixed prostheses is increasing. Aquaflosser (AQ) and Waterpik (WP) are
examples of these oral irrigating devices that were introduced to the dental market
recently. They can be effective in removing dental biofilm from different surfaces.
Purpose of study: The purpose of this study is to evaluate biofilm formation on three
fixed dental substructures and to evaluate the efficacy of two oral irrigating devices
on biofilm removal from these three substructures
