Evaluating an oral and dental hygiene education based on motivational interviewing in patients with fixed orthodontic appliances 2020-07-22 anticipated 30 Complete https://irct.ir/trial/51985 interventional Randomization: N/A, Blinding: Not blinded, Placebo: Not used, Assignment: Single, Purpose: Education/Guidance. 2 patients undergoing fixed orthodontics. Educational intervention is done in the form of counseling and motivational interview with the patient in the presence of his parents. First, the researcher states the purpose of the consultation and provides information about the causes of gingivitis, how dental plaque forms, and the effect of sugary and acidic foods on caries. Then we talk about the reasons that may affect dental hygiene behaviors. For example, the patient is asked not to delay the time of brushing so that fatigue does not prevent the control of plaque, or be sure to brush each time after the main meals. Apply fluoridated toothpaste, lasting at least two minutes at a time, and after brushing try to simply spit out the water and preferably not rinse the mouth with water. It is recommended that parents monitor their children's brushing. It also explains how oral health control affects the freshness of breathing and improves social relationships and acceptance of others. It is also noted that in the new conditions created by orthodontics in the mouth, the need for increased plaque control should be thoroughly cleaned. The patient is asked to comment and ask questions, positive behaviors are encouraged, identification problems and possible solutions are provided. Then the child is taught to brush and floss first on the model and then inside the mouth. During this stage, the patient follows the steps with the mirror he has, and in the next stage, the patient must repeat what he has learned in front of the mirror . A brochure containing information on how to brush and floss properly is also provided at the end. To motivate and be more effective, the patient is called once a week during the intervention, which is about a month.. No - There is not a plan to make this available Justification or reason for not sharing IPD is Still under investigation.
