quiz 106 Dental dams

single tooth isolation

is used for selected restorative procedures for endodontic treatment, 1 or 2 teeth

multiple tooth isolation

3-4 teeth , when anterior teeth are being treated maximum stability is achieved by canine to canine

key punch hole

In dental dam application, the hole that covers the anchor tooth. it is placed one or two teeth distal to tooth receiving the treatment

Anchor tooth

tooth on which the dental dam clamp is placed; usually one or two teeth distal to the tooth or teeth being restored

punching a hole too large

dam will not fit tightly around the tooth, saliva can leak through

punching a hole too small

dam will not slip easily over the tooth, dam can stretch and tear

punching a hole too close

dam can stretch or tear leaving gingiva exposed and can cause leakage

punching a hole too far

excess material is present between the teeth blocks dentals vision

winged clamp

height of contour

widest part on the facial and lingual tooth

the clamp must

be positioned with all four prongs firmly in place on the tooth before the clamp forceps are loosened

Posterior dental dam clamps

Used for the maxillary and mandibular posterior teeth, these are universal and can be clamped on either quadrant

Clamps 7 and W7

universal mandibular molar clamps

Clamps 8 and W8

universal maxillary molar clamps

Clamps 9 and W9

anterior dental clamps

anterior dental clamps are

designed to retract the gingiva on facial surface, improve visibility for the restoration of cervical class V cavities, permit isolation of an anterior tooth during endodontic treatment

Water-based lubricant

placed on the underside of the dam to help materials slide over the teeth and through inter-proximal spaces

petroleum based lubricant

placed on patients lips for comfort

dont use petroleum based

on dam it interfers with the setting of dental materials
