Assisting patient with dental floss (EFDA) --CORRECT ANSWER--Preparing
the floss
1) Cut a piece of floss about 18 inches long. Wrap the excess floss around the
middle or index fingers of both of your hands, leaving 2-3 inches of working
space exposed.
2) Stretch the floss tightly between your fingers, and use your thumb and index
finger to guide the floss into place.
3) Hold the floss tightly between the thumb and forefinger of each hand. These
fingers control the floss and they should be no farther away than 1/2 inch apart.
Flossing the teeth
4) Pass the floss gently between the patient's teeth, using a sawing motion.
Guide the floss to the gumline. Do not force or snap the floss past the contact
area. The floss may cut or injure the tissue.
5) Curve the floss into a C shape against one tooth. Slide it gently into the space
between the gingiva and the tooth. Use both hands to move the floss up and
down on one side of the tooth.
6) Repeat these steps on each side of all teeth in both arches; including the
posterior surface of the last tooth in each quadrant.

,7) As the floss becomes frayed or soiled, move a fresh area into the working
position.

Using an instrument intraorally (EFDA) --CORRECT ANSWER--1) Seat and
place the pt in the supine position.
2) Position yourself as the operator.
3) Adjust the dental light to illuminate the oral cavity.
4) Using a pen grasp, pick up the mirror with your nondominant hand and the
explorer with your dominant hand.
5) Instruct your pt to open his/her mouth and turn toward or away from you,
depending on the location of the mouth.
6) Establish a fulcrum close to the area that you will be exploring with your
instrument.
7) Adapt the explorer to the most posterior tooth in the upper right quadrant. A
well-adapted instrument prevents damage to the tooth and surrounding tissue.
8) Follow around the tooth with the mirror and the explorer, and examine all
surfaces through visualization and touch.

,Preparing, placing, and removing the dental dam (EFDA) --CORRECT
ANSWER--Patient preparation
1) Check the pt's record for contrainidications, and identify the area to be
isolated. Inform the pt of the need to place a dental dam, and explain the steps
involved.
2) Assist the dentist in the administration of local anesthetic. The dentist will
determine which teeth are to be isolated and will note whether any malposed
teeth must be accommodated.
3) Apply lubricating ointment to the pt's lip with a cotton roll or cotton-tipped
applicator. Pt's comfort is a matter of concern throughout placement and
removal of the dental dam.
4) Place yourself in the operator's position, and adjust your pt for easier access.
5) Use the mouth mirror and the explorer to examine the site where the dam is
to be placed. It should be free of plaque and debris. If the dam is placed in an
area with plaque and debris, the dam could push the plaque and debris into the
sulcus and irritate the gingival tissues. If debris and plaque is present, selective
coronal polishing is performed on these teeth before dam is applied.
6) Floss all contacts involved in placement of the dental dam. Any tight contacts
may tear the dam.
Punching the dental dam
7) Use a template or stamp to mark on the dam the teeth to be isolated.
8) Correctly punch the marked dam according to the teeth to be isolated. Be
sure to use the correct size of punch hole for the specific tooth.

, 9) If teeth have tight contacts, lightly lubricate the holes on the tooth surface
(undersurface) of the dam. This eases placement of dam.
Placing the clamp and the frame
10) Select the correct size of the clamp.
11) Secure the clamp by tying a ligature of dental tape on the bow of the clamp.
12) Place the beaks of the dental dam forceps into the holes of the clamp. Grasp
the handles of the dental dam forceps, and squeeze to open the clamp. Turn
upward, and allow the
Applying topical fluoride gel or foam (efda) --CORRECT ANSWER--Selecting
the tray
1) Select a disposable tray that is of the appropriate size for the patient's mouth.
The tray must be long and sufficiently deep to cover all erupted teeth
completely without extending beyond the distal surface of the most posterior
tooth. Trays are available in sizes to fit primary, mixed, and adult dentition. If
the patient's mouth can accommodate it, you may use a double-arch tray. This
saves time by treating both arches at the same time. Remember, trays are
discarded after a single use & if you try a tray in the mouth but do not use it that
tray must be discarded.
