Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcomes of the study are the presence of dental plaque (measured with a modified Silness and Loë Plaque Index), gingival bleeding (measured with the Bleeding on Marginal Probing Index), and self-reported oral health behaviors. The plaque index will be used to describe the amount of plaque on the buccal surfaces of the first premolars, canines and incisors using a mouth mirror and a probe. The buccal surface of each tooth is divided into four zones according the position of the orthodontic bracket: mesial, distal, gingival and incisal to the bracket. Each of the four sites of the buccal tooth surface is given a score from 0 (absence) to 3. For the bleeding score, three sections (mesio-vestibular, vestibular, disto-vestibular) of the vestibular surfaces of the first premolar, canines and incisors will be assessed to determine whether probing elicited marginal bleeding (score 1) or not (score 0). Data are collected at baseline, and 6 and 12 weeks follow-up. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcomes include changes in psychosocial factors of the HAPA model, such as outcome-expectancies, intention, action-self-efficacy, coping planning and action control. A self-administered digital questionnaire contains questions with both single and multiple response items concerning oral health behaviors and their psychosocial factors. Data are collected at baseline, and 6 and 12 weeks follow-up. | — |
