Exam 2 CH 41 Nonsurgical Therapy

Question 1

Term; LPS complex found in cell wall of many gram-negative microorganisms; contained superficially within periodontally involved cementum

Answer 1

Endotoxin

Question 2

Term; Dental biofilm removal and control, supragingival and subgingival scaling, root planning, and adjunctive treatments such as the use of chemotherapy; the basic objectives are to restore periodontal health; arrest or slow the progression of early periodontal disease; for more advanced disease, to prepare the tissues for more complex periodontal therapy

Answer 2

Nonsurgical periodontal therapy

Question 3

What is the focus of treatment?

Answer 3

• Elimination of the contributing factors of the infection

- the primary sources of infection are periodontal pathogenic microorganisms in the biofilm

Question 4

Term; The therapeutic washing of the pocket and root surface to remove endotoxins and loose debris?

Answer 4

Lavage

Question 5

Term; Ultrasonic scaling device that generates a magnetic field and produces tip vibrations by the expansion and contraction of a metal stack or rod?

Answer 5

Magnetostrictive

Question 6

Term; Ultrasonic scaling device activated by dimensional changes in crystals housed in the handpiece?

Answer 6

Piezoelectric

Question 7

Term; Type of mechanical power-driven scaler that functions from energy delivered by a vibrating working tip in the frequency of 2,500-7,000 cps; driven by compressed air, the handpiece connects directly to a conventional rotary handpiece tubing

Answer 7

Sonic Scaler

Question 8

Term; Magnetostrictive inserts made of flat metal strips stacked, or sandwiched, together; metal in stack acts like an antenna to pick up magnetic field and cause vibration?

Answer 8

Stack

Question 9

Term; Action created by the formation and collapse of bubbles in the water by high frequency sound waves surrounding an ultrasonic tip

Answer 9

Cavitation

Question 10

What is the purpose of the O-ring?

Answer 10

Holds tip in place and seals the water

Question 11

What is the expected outcome of Nonsurgical Therapy?

Answer 11

Interrupt or stop the progress of disease: reduce formation of dental biofilm

Question 12

What are the changes in bacterial flora after NSP?

Answer 12

Subgingival bacteria flora is changed from primarily anaerobic, gram-negative, motile forms to aerobic, gram-positive, nonmotile.

Question 13

Water spray does what in ultrasonic scaling?

Answer 13

Keeps the water tip cool.

Question 14

What does oscillation do in ultrasonic scaling?

Answer 14

Oscillation of tip; turbulence=disruptive effect

Question 15

Term; A minimally invasive diagnostic procedure used in medicine to examine inaccessible tissues by inserting a fiber-optic tube into the body?

Answer 15

Endoscopy

Question 16

Term; Treatment by means of chemical or pharmaceutical agents?

Answer 16

Chemotherapy

Question 17

Term; Tubular instrument placed in a cavity to introduce or withdraw fluid?

Answer 17

Cannula

Question 18

Term; Available for absorption by the body?

Answer 18

Bioabsorbable

Question 19

Term; Susceptible of degradation by biological processes, as by bacterial or other enzymatic action

Answer 19

Biodegradable

Question 20

Term; Area on tooth where instrumentation is confined; area where calculus and altered cementum are located and treatment is required?

Answer 20

Instrumentation zone

Question 21

Term; Use of specific chemical or pharmaceutical agents for the control or destruction of microorganisms, either systemically or at specific sites?

Answer 21

Antimicrobial therapy

Question 22

The system of scaling in two long appointments completed within a 24 hour period under anesthesia with assistance of a chair side assistant?

Answer 22

Full mouth disinfection

Question 23

Which sterilization method should be avoided for ultrasonic tips?

Answer 23

Question 24

What is the main action of the ultrasonic and sonic scaler?

Answer 24

Mechanical Action

Answer 25

42

Question 26

What is the most significant measure of success in periodontal debridement?

Answer 26

Tissue response

Question 27

Tissue response is manifested by clinical features commonly referred to as the?

Answer 27

Endpoints of therapy

Question 28

Endotoxins are embedded in what areas?

Answer 28
