摘要：
A dental mirror instrument has a light waveguide and an airflow conduit that extend along the length of an elongated member to a mirror portion. An airflow exiting from the airflow conduit may be directed over the mirror surface to remove fluids and debris. Light from a light source is transmitted along the light waveguide and is reflected off of a back-side of a land portion through a Fresnel lens to produce a task light. A mirror may have a hydrophobic surface and this surface may have raised portions or a patterned surface that further enhances the removal of fluids or debris. The optical component of the dental instrument may be detachable to a source component and may be disposable. A flexible connector may be coupled with the source component to provide an airflow to the airflow conduit and/or electrical power to the light source.
