And it’s uses in Dentistry.

 Infection control  Accidental aspiration  Moisture control  Visibility  Efficiency  Retract lips, tongue, and tissue  Protects tooth from contamination (Saliva)

 Asthma  Respiratory congestion  Allergies to latex  Herpetic Lesions  Lesions of the commissures  Claustrophobic  Bad experience

 Explain procedure to patient  Check medical history for latex allergy  Tooth should be free of plaque and debris

 Made of latex or latex free materials  Sizes, Thickness, Color, and Scents  Adult 6x6  Children's 5x5  Thin is usually for RCT.  Medium is used for restorations.  Thick is used as needed for stronger tissue retraction.

 Dental Dam Napkins  A disposable napkin is placed between the patients face and the dam.  Helps to absorb moisture and increase the patients comfort.  Protects the patients face from direct contact with the dental dam to decrease latex sensitivity.

 Dental Frames  Plastic U shaped Frame  Otsy Frame  Young's‘ Frame

 A stamp is can be used to mark the dental dam with predetermined markings to be punched out by the assistant.

 Template  A template has holes where the teeth should be marked. It’s placed on the dental dam and a pen is used to mark through the template to indicate the location where to punch the hole.

 IF holes are:  Too big – Dam will not fit tight  Too small – Dam will tear when going over teeth  Too close – Dam will stretch to far – leakage  Too Far apart – too much material between teeth – will bunch

 Clamps to the Anchor tooth  Stabilizes the dental dam  Opposite end of the dental dam must be stabilized (also called ligating the dam) a. Can use another clamp. b. Can use a stabilizing cord-Wedget. c. Can use dental floss or tape.

 Clamps are available in many sizes.  Winged clamp  Extra extensions for better retraction and retention  Help retain the dental dam in place because the wings are angled toward the gingival.  Used during the one-step dental dam placement method.

 Wingless Clamps  Do not have any projections.  Names usually begin with a W (ex. W7)  Used during the two-step dental dam placement method.  Clamps that begin with “A” have jaws that bend sharply downward toward the gingiva.  Clamps without the “A” have jaws that are on a flat plane

 Universal means that the same clamp may be placed on the same type of a tooth in the opposite quadrant.

 Also called Cervical clamps or 9 and 9W.  Designed to:  Retract gingiva or facial surface gum tissue.  Improves visibility for the restoration of a cervical class V cavity.  Isolates anterior tooth during RCT procedures.

 Bow  Arched metal  Jaw  Expanding  Forceps hole  Forceps attach  Jaw point s  Contact tooth

 Punch plate  Stylus

 Beaks  Lock – sliding bar  Never leave in locked position

 Lubricate the patients lips.  Inversion- tuck the dental dam around the tooth.  Stabilizing cord- Wedgets  Ligatures- Means to tie down, can use floss or tape.  Single tooth isolation- A one hole punch.

 Multiple tooth isolation  6 to 8 isolated teeth provides the most stability.  Remember to include 1-2 teeth posterior to the tooth being treated.

 Missing fragments  Tears in the material  Cut or ripped septa  Always check the interproximals of all the teeth involved, and if you should discover cut or ripped septa in between the teeth, gently floss it out.

 Tell the Patient what you’re about to do, and explain the steps.  Select the proper clamp for the tooth that you’re going to anchor.  Punch the desired holes for the arch that you are working on.  Decide whether you’ll use a one step or two step procedure in placing your rubber and clamp.  Using the forceps, place the clamp on the tooth.  Then your frame.  Then stretch your holes over the teeth and use a wedget to secure it.  Floss the dental dam down in between the teeth, and use your greg 4/5 to invert the material.  Dry the surface of the dental dam and prepare to begin procedure.

 When preparing a tooth for a restoration often there are times we will need to have an artificial wall in place of the missing wall of surface.

 Replaces the missing walls of the tooth.  Restores natural contours to the tooth structure.  Prevents excess materials from getting near the gum tissues (gingiva).

 Tofflemire matrix- Used with a tofflemire retainer, to replace the walls of the prep.  Automatrix- A preformed band that is placed around the tooth, and tightened with a tightening device.  Clear Mylar strips- A clear strip that placed around the anterior teeth to hold and form the composite in the prep.  Shell matrix- Premolar and molar size.

 Tofflemire retainers are most commonly used when the posterior amalgams are placed ex. (Class ll)  The larger circumference is the occlusal edge.  The smaller circumference is the gingival edge.  The center of the matrix band must be shaped in the proximal contact area so it will make contact with the tooth next to it.

 Triangular or round wedges.  Made of plastic or wood.  Placed into the embrasure to position matrix band firmly against gingival margins of the preparation of the surface to be restored.  They also slightly separate the teeth when necessary.

 Placed with  Hemostat  Cotton Pliers  Howe Pliers  Placed from the lingual surface

 The results of an improperly placed wedge and band- a. Overhang- excess restoration material extending beyond the preparation. b. Cupping- a gap of indention in the restoration.
