APPARATUS AND METHODS FOR PERFORMING A DENTAL COLD SENSITIVITY TEST AND FOR CONTROLLING SWAB SATURATION

Abstract:

The present disclosure is generally directed to a swab and an apparatus for testing dental cold sensitivity. The swab comprises a hollow tube and an absorbent tip fixedly attached to the distal end of the hollow tube. The dispensing apparatus includes a pressurized container and an actuator. The actuator may include a flow control valve to limit the flow of coolant to the absorbent tip or to limit the volume to a metered dose and to prevent the swab from being ejected from the actuator due to excess force.
