Abstract (en)

[origin: WO9922663A1] A filter is disposed along a flow path for fluid to be supplied to a dental patient's mouth. In preferred embodiments, the filter includes a microporous membrane, which may be capable of removing endotoxins or other pyrogens from fluid being filtered. The filter may be installed inside or outside a dental instrument. The filter improves the safety of dental procedures by preventing microorganisms and other undesirable substances from being introduced into a dental patient's mouth.
