Hirschfeld's method

Hirschfeld's method

Etymology: Isador Hirschfeld, American dentist, 1881-1965

a tooth-brushing technique in which the bristles are vigorously rotated in very small circles against the gingivae and the axial surfaces of the teeth at a slight incisal or occlusal angle.

---

method,

n a manner of performing an act or operation; a technique.

method, Callahan's,

n.pr See method, chloropercha.

method, Charters',

n.pr a method of toothbrushing in which the brush is held horizontally, with the bristles lying against the teeth and gingivae and pointed in a coronal direction at 45 degrees so that the bristles lie half on the teeth and half on the gingivae. A vibratory cycle of a very constricted diameter is negotiated so that the brush head moves in a circular movement but the brush bristles remain fairly stationary while being agitated. The circular vibration loosens debris and pumps the bristles into interproximal areas to massage the tissues.

method, chloropercha

(klō´rpur´ch),
n (Callahan's method, Johnston's method), the method of filling root canals in which gutta-percha cones are dissolved in a chloroform-rosin solution in the root canal. The canal is flooded with the chloroform solution. A preselected gutta-percha cone is then pumped carefully into and out of the canal. As the cone dissolves, the material is forced into the apex as a plastic mass. Other cones and occasionally additional chloroform solution are added until the canal is sealed.

method, Collis,

n a variation of toothbrushing that employs short, repetitive strokes with a Collis curved brush. Collis's brush design allows for brushing three surfaces of the tooth simultaneously. A 45° angle is used when brushing in and around the gingivae line. Favored by special needs patients, as well as parents and caretakers who perform the task of brushing for others. Also called
simultaneous sulcular.

method, Fones',

n.pr (Fones' technique), a toothbrushing technique in which, with the teeth occluded and with the brush at more or less right angles to the teeth, large sweeping, scrubbing circles are described. With the jaws parted, the palatal and lingual surfaces of the teeth are scrubbed using smaller circles. Occlusal surfaces are brushed in an anteroposterior direction.

method, Hirschfeld's,

n.pr a toothbrushing method in which the bristles are placed against the axial surfaces of the teeth, with slight incisal or occlusal inclination from a right-angled application, in simultaneous contact with teeth and gingivae, and then rotated in a circle of exceedingly small diameter. Occlusal surfaces are brushed energetically.

method, Howard's,

n.pr a method of artificial respiration. The patient is placed on the back, with the hands under the head, and a cushion is placed so that the head is lower than the abdomen. The physician applies rhythmic pressure upward and inward with the hands against the lower lateral parts of the patient's chest.

method, Howe's silver precipitation,

n.pr a method of depositing silver in enamel and dentin by the application of ammoniacal silver nitrate solution and its reduction with formalin or eugenol.

method, indirect restorative,

n the technique of fabrication of a restoration on a cast or model of the original (e.g., the indirect method of inlay construction, in which a die of amalgam or other material is made from an impression of the prepared tooth, a wax pattern is formed, and the cast inlay is fitted and finished on the die and then cemented to the tooth).

method, Johnston's,

n.pr See method, chloropercha.

method, lateral condensation,

n the method in which a preselected gutta-percha cone is sealed into the apex of the root. The balance of the space is filled with other gutta-percha cones forced laterally with a spreader.

method, Leonard,

n.pr a method of teeth cleaning that advocates a vigorous drawing of the toothbrush up and down across the teeth. The teeth are held apart, so that each section is brushed separately. Also known as
vertical toothbrushing.

method, modified Stillman,

n.pr a toothbrushing technique characterized by the placement of the toothbrush head against the gingiva, vibrating it, then rolling the bristles over the rest of the tooth's surface. Each stroke is repeated five times for each section of the oral cavity.

Modified Stillman method.

method, prebook,

n a method of scheduling appointments in which the patient schedules the next appointment while checking out from the current one. A reminder postcard is filled out at this time, to be mailed later, or an e-mail reminder is stored.

method, rolling stroke,

n a simple, introductory toothbrushing technique that does not include brushing of the gingival sulcus. Often taught to children as a precursor to the modified Stillman method, or as a preliminary framework for a more advanced technique incorporating vibration of the brush.

method, segmentation,

n the method in which a preselected gutta-percha cone is cut into segments. The tip section is sealed into the apex of the root. The other segments are usually warmed and condensed against the first piece with a plugger. Additional pieces are then used until the space is obliterated.

method, silver cone,

n the method in which a prefitted silver cone is sealed into the apex of the root canal. The space not sealed with the cone is obliterated with gutta-percha or sealer.

method, Smith's,

n.pr a toothbrushing technique referred to as physiologic, in which the brush strokes mimic the path taken by food when it is chewed.

method, SOAP (subjective, objective, assessment, plan),

n an acronym for the method for making notes to the problem-oriented record in which S stands for subjective data obtained from the patient or family;
O refers to objective data acquired by observation, inspection, or testing;
A relates to the assessment of the patient's current situation and progress made throughout the course of treatment; and
P represents the actual patient care plan.

method, split cast,

n 1. a procedure for checking the ability of an articulator to receive or to be adjusted to a maxillomandibular relation record.
n 2. a procedure for indexing casts on an articulator to facilitate their removal and replacement on the instrument.

method, Stillman's,

n.pr a toothbrushing technique that incorporates gingival stimulation and dental cleansing, in which the toothbrush is held against both the gingival and the dental surfaces and manually vibrated.

method, sulcal

n a toothbrushing technique for controlling plaque involving placement of the bristles in the sulcus at an angle of 45° to the tooth's long axis and vibrating the bristles in a quick manner from side to side. Also called the
Bass method.
