---

stroke,

n 1. a single, unbroken movement made by an instrument or the mandible.
2. a colloquial term for accident, cerebrovascular.

stroke, circular,

n an unbroken spherical movement of approximately 1 to 2 mm in diameter, combined with pressure, that is used to apply paste in polishing.

stroke, circumferential

n a movement used for root and gingival curettage; the blade of the periodontal curet is negotiated mesiodistally while it is in contact with either the root or the inner aspect of the soft tissue wall of the gingival or periodontal pocket.

stroke, exploratory,

n a phase of subgingival root scaling in which the curet is held in a featherlike grasp to ascertain tactilely the amount and extent of the deposits on the root surface; the ingress stroke into the pocket area.

stroke, horizontal,

n a short movement against a tooth that is made parallel to its occlusal surface.

stroke, oblique,

n a single, continuous diagonal movement of an instrument over the external face of the object being worked on.

stroke, placement,

n a single, continuous movement of an instrument over the surface of an object being worked on, which moves the instrument at the intended location.

stroke, power,

n the phase of the working stroke that is designed to split or dislodge calculus from the root surface. It is prefaced by the exploratory stroke and followed by the shaving stroke.

stroke, probe walking,

n the technique of assessing the progression and extent of disease within the oral cavity by inserting a periodontal probe into the sulcus or pocket of the tooth and moving the device up and down between 1 to 2 mm in height while simultaneously advancing forward in 1 mm increments.

stroke, pull,

n a single, continuous movement of an instrument over the surface of an object being worked on. A pull stroke is enacted to remove calculus from the surface of a tooth.

stroke, push and pull,

n the technique of using a subgingival explorer vertically or diagonally to assess a defect of the tooth's surface by inserting the lower shank of the instrument under the gingival margin and into the sulcus or pocket and moving the device up and down while simultaneously applying equal pressure and advancing forward.

stroke, shaving,

n the phase of the working stroke of a periodontal curet that is designed to smooth or plane the root surface. It follows the power stroke, which is designed to dislodge calculus from the root surface.

stroke, vertical,

n a single, continuous movement of an instrument over the external face being treated. The vertical stroke is in a direction that parallels the length of the tooth (from the root to the occlusal surface).

stroke volume,

n the volume of blood put out by the heart per heartbeat. It is directly proportional to the volume of blood filling the heart during diastole.

stroke, working,

n a single, continuous movement of an instrument that achieves a task or treatment.
