Although all of the following procedures may be necessary phases of periodontal therapy, which of these is absolutely essential for successful treatment and a favorable prognosis?:

Thorough scaling, root planing and curettage

Final evaluation and maintenance on a three-month recall

Periodontal surgery for pocket elimination

Elimination of local etiologic factors through plaque control instruction, and reinforcement at each appointment .

The most effective time to give plaque control instructions on any scaling appointment is:

Before periodontal exam and charting.

After examination and before scaling.

After scaling and before polishing.

After scaling and polishing.

The sequence is not important.

Teeth in the region should be scaled before:

Plaque control instruction is begun.

Before establishing a treatment plan for scaling and root planing it is essential to determine the:

Location and depth of pockets.

Location, nature, and extent of the calculus deposits.

All of the above.

When oral hygiene instruction is given during a scaling appointment, it should:

Follow scaling of the sextant or quadrant.

Decomposes.

Rolling the handle of the explorer between the thumb and fingers is important because it:

Is a key to adapting the working end around line angles and in depressions.

Can cause laceration of the tissue.

Decreases tactile sensitivity.

A very tight grasp will:

Increase tactile sensitivity.

Prevent muscle fatigue of the fingers.

Incorrect adaptation of the tip as shown above would result in:

Gouging of the root surface.

Failure to detect calculus.

Laceration of the tissue with the tip.
