Prepare to Quit - A Clinical Trial to Help People Quit Smoking in a Community Dental Clinic Setting

October 25, 2016 updated by: Dr. Douglas James Brothwell, University of Manitoba

Prepare to Quit - A Randomized Clinical Trial to Help People Quit Smoking in a Community Dental Clinic Setting

The objectives of this study are:

  1. To determine the effect that an intensive, community dental clinic centered, stop-smoking program using a motivational interviewing approach has upon cessation rates for interested, smoking inner-city dental patients.
  2. To determine the effect that providing a tooth whitening incentive, in a community dental clinic stop-smoking program, has upon cessation rates for interested, smoking inner-city dental patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Motivational Counseling
The extended counseling group will receive one to three, 45-minute individual motivational counseling sessions using a motivational interviewing approach to Express empathy, Develop discrepancy, Roll with resistance, and Support self-efficacy.
Behavioral: Motivational Counseling
Normally three counseling sessions. Session #1: Introductions; discuss habits, feelings, pros and cons of smoking; degree of addiction; previous quit attempts and relapse; reinforce patient confidence; open-ended questions to illicit self-efficacy; homework includes Pack-Track and Why Test. Session #2: Discuss smoking patterns, triggers, and risk situations; discuss methods to resist triggers, need for medications; prepare environment and back-up plan; discuss quit date; homework to review self-help workbook. Session #3: Reinforce previous concepts; review resistance plan; discuss and arrange pharmaceutical cessation aids; set quit date; homework to finalize all self/home preparations; offer tooth polishing on quit date; follow-up by telephone or appointment.
Other Names:
  • Motivational Interviewing
Experimental: Tooth Whitening Incentive
The tooth whitening group will receive all of the interventions previously described for the Motivational Counseling Group, and as an extra incentive against relapse, will also be offered complimentary tooth whitening procedures if biochemically verified as tobacco-free by Carbon Monoxide monitor (bleaching at 3-weeks, whitening strips at 3-months, and whitening touch-up at 1 year).
Behavioral: Motivational Counseling
Normally three counseling sessions. Session #1: Introductions; discuss habits, feelings, pros and cons of smoking; degree of addiction; previous quit attempts and relapse; reinforce patient confidence; open-ended questions to illicit self-efficacy; homework includes Pack-Track and Why Test. Session #2: Discuss smoking patterns, triggers, and risk situations; discuss methods to resist triggers, need for medications; prepare environment and back-up plan; discuss quit date; homework to review self-help workbook. Session #3: Reinforce previous concepts; review resistance plan; discuss and arrange pharmaceutical cessation aids; set quit date; homework to finalize all self/home preparations; offer tooth polishing on quit date; follow-up by telephone or appointment.
Other Names:
  • Motivational Interviewing
Behavioral: Tooth Whitening
1. A dental check-up will ensure the absence of contraindications to tooth whitening (cavities, soft tissue pathology, severe periodontitis) 2. Removal of calculus, plaque, or stains with a dental polishing 3. Treatment time is approximately 1 hour total4. Lips are retracted, tongue protector is placed and protective eyewear used 5. Saliva is suctioned and teeth are air dried 6. A liquid rubber dam material is applied to protect gums and cured by visible light. 7. The bleaching material is placed on the enamel surface of the involved teeth and is replaced if drying occurs 8. After 15 minutes, the bleach is suctioned, mouth rinsed and process repeated 9. Three to four applications are typically used
Other Names:
  • Extrinsic vital bleaching
