| thickness of dental dam | the thickness or gauges are usually thin (light), medium, and heavy |

| medium | ____ thickness is widely used in operative procedures |
| heavy | ___ thickness is selected when tissue retraction and extra resistance to tearing is important |
| dental dam frame | a frame or holder is necessary to stabilize and stretch the dam so that it fits tightly around the teeth and is out of the operator's way |
| plastic and metal | frames are available in ____ and ____ |
| plastic U shaped frame | what frame is placed under the dam, it is radiolucent |
| young's frame | stainless steel U shaped holder with sharp projections on it's outer margin's, placed on the outside of the dam and is stretched over the projection of the frame, the patient feels comfortable by holding it away from the patient's face |

| dental dam clamps | the ___ ___ ____ are the primary means of anchoring and stabilizing the dental dam |
| bow | rounded portion of the clamp |
| jaws | the ___ encircle the tooth and are shaped into four prongs, all four prongs must be firmly seated on the tooth to create the facial to lingual balance necessary to stabilize the clamp |

| fitting the dental dam clamp | the jaws of the clamps are designed to fit on the cervical area of the tooth below the height of contour and at or slighly below the CEJ |
| posterior dental dam clamps | for the maxillary and mandibular posterior teeth |
| anterior dental dam clamps | used to retract the gingiva on the facial surface, improves visiblitiy for the restoration of the cervical class 5 cavities, permits isolation of an anterior tooth during endodontic treatment |
| ligatures | dental floss should always be attached to the bow , it is an important safety step that must always be done, the ligature makes it easy to retrieve a clamp if it should accidentally fall off the tooth |
| poked through holes | teeth are isolated when ___ ____ ____ |
| one step method | the dam and clamp are placed at the same time |
| two step method | first the clamp is placed and then the dental dam material is stretched over it |
| root canals | plastic frames and butterfly clamps are used for ___ ____ |
| throat | the bow always goes towards the ___ on the occlusal surface |
| malaligned | displaced out of line, especially teeth displaced from normal relation to the line of the dental arch |
| posterior | 6 by 6 inch is used for ________ teeth |
