Transtheoretical model of behavioral change associated with caries risk eating behavior.

Stages of Change Defined by Prochaska and Di Clemente [41]	Definition of the Stage of Change	Example in the Presence of a Caries Risk Eating Behavior (Soda Consumption)
1—Pre-contemplation	The patient is not involved. The patient does not consider any action in favor of a change in behavior within six months.	The patient does not change sugar intake.
2—Contemplation	The patient is concerned and heeds the information. He/she expresses the intention to change his/her behavior in the next six months and may take a first step.	The patient agrees to complete a weekly sugar drink diary to estimate the daily consumption of sugar.
3—Preparation	The patient prepares for the action-decision to change: he/she intends to act in the short term (within 30 days) with a stated realistic plan.	The patient speaks in favor of decreasing the frequency of soda intake.
4—Action	Initiation of change: implementation of a new behavior: The patient has concretely engaged in observable actions to modify his/her behavior during the last six months. These actions must be sufficient to promote health and be maintained over time.	The patient chooses sugar-free sodas and implements a gradual and quantifiable reduction in intake: only during meals, then only one per day, then one per week, and then reserved for festive moments... and uses a straw. At this stage, it must be encouraged.
5—Relapse	Maintaining the change. Maintainence of his/her behavior for a period of more than six months, with vigilance for relapse.	The patient comes to the follow-up consultations over a long period of time and maintains the new oral health behaviors.
