Q: Mrs. Jones came into the office with her daughter Jan, who is in for her 6-month recare appointment. Jan will soon be getting orthodontic appliances, and Mrs. Jones asks you how they will be attaching the braces. You explain:
- the orthodontic brackets and bands will be cemented to the teeth
- the orthodontic brackets and bands will be bonded to the teeth
- the orthodontic brackets will be cemented and the bands will be bonded to the teeth
- the orthodontic brackets will be bonded and the bands will be cemented to the teeth
A: the orthodontic brackets will be bonded and the bands will be cemented to the teeth

Q: Removal of orthodontic appliances requires a debonding/cement removal appointment. Removal of brackets may cause more damage to the surface of the tooth due to:
- higher bond strength in cements than in resins
- higher bond strength in resins than in cements
- the use of carbide finishing burs
- both B and C
A: both B and C

Q: You have just completed debonding on your patient Mary Ann. At the end of the appointment, Mary Ann's mother is very concerned about the “white spots” on Mary Ann's teeth, especially since she was an excellent brusher. What procedure could help you determine whether the spots were a result of the orthodontic treatment?
- Taking a Panorex radiograph
- Taking bitewing radiographs
- Taking good impressions
- Taking good before/after intraoral photos
A: Taking good before/after intraoral photos

Q: When placing brackets on the teeth, which one of the following steps helps to provide greater strength for retention?
- Polishing the tooth with a fluoride paste before bracket placement
- Using a carbide finishing bur on the tooth before bracket placement
- Using a pumice paste before bracket placement
- Using acid etch before bracket placement
A: Using acid etch before bracket placement

Q: Which one of the following procedures will provide the greatest amount of protection to the surfaces of the teeth immediately after bracket placement?
- Having the patient brush immediately
- Applying a fluoride varnish
- Having the patient use a disclosing agent
- Having the patient rinse with mouthwash
A: Applying a fluoride varnish

Q: Which one of the following resin properties provides additional strength but can be more difficult to remove when debonding?
- Heavily filled resins, longer etching time
- Heavily filled resins, shorter etching time
- Lightly filled resins, longer etching time
- Lightly filled resins, shorter etching time
A: Heavily filled resins, longer etching time

Q: When debonding and removing resin on the tooth, the proper steps for removal are:
- use moderate pressure, keeping the finishing bur on the tooth at all times
- use light pressure, keeping the finishing bur on the tooth at all times
- use moderate pressure and a brush-like stroke with the finishing bur
- use light pressure and a brush-like stroke with the finishing bur
A: use light pressure and a brush-like stroke with the finishing bur

Q: The bond strength of the bracket is greater if:
- a heavily filled resin and a thinner layer of material is used
- a heavily filled resin and a thicker layer of material is used
- a lightly filled resin and a thinner layer of material is used
- a lightly filled resin and a thicker layer of material is used
A: a heavily filled resin and a thinner layer of material is used

Q: Your patient John is in for his 6-month recare appointment. You see that John has full orthodontic appliances. He asks you to explain how you are going to clean his teeth with all of the wires and brackets in place, and you reply:
- I will use an ultrasonic instrument
- I will use a pointed rubber cup
- I will use a carbide finishing bur
- I will use a brush attachment on the prophy angle
A: I will use an ultrasonic instrument

Q: Which one of the following is the ideal debonding technique?
- Laser
- Carbide finishing bur
- Ultrasonic instrument
- None of the above
A: None of the above

Q: Bands are generally removed with:
- a YAG laser
- orthodontic pliers
- a carbide finishing bur
- an ultrasonic scaler
A: orthodontic pliers

Q: You have just finished a prophylaxis on your 16-year-old patient, Tom, who recently had his braces removed. Upon checking the facial surface of #22 and 25, you notice a light gray line left behind from the explorer on the surface of the tooth. What is this a result of?
- The gray line indicates possible fluorosis
- The gray line indicates biofilm accumulation
- The gray line is due to using an explorer that is too sharp
- The gray line indicates that residual resin is abrading the explorer
A: The gray line indicates biofilm accumulation

Q: Which appliance is used to give support to the teeth while the bone and other supporting tissues are stabilizing after the removal of fixed appliances?
- Bracket
- Band
- Elastomer
- Retainer
A: Band

Q: Your patient Michael has just been given his new retainer. What instructions should you give him?
- Keep the retainer wrapped in a Kleenex or paper towel when not wearing it
- Keep the retainer in a container with water when not wearing it
- Keep the retainer in the mouth continuously
- Avoid cleaning the retainer, as this can damage it
A: Keep the retainer in a container with water when not wearing it

Q: At the end of the debonding appointment, which one of the following should be performed?
- An impression and bite registration is taken
- Sealants are placed
- Periodontal charting is completed
- All of the above
A: Periodontal charting is completed
