Abstract
Undesired contact with dental debris is minimized by a disposable dental trap which is provided with a removable top cover and a pivotable handle. The useful capacity of the trap is increased with a corrugated filter which increases the available filter surface area and thereby reduces the frequency of trap replacement.
