Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Distance and rate of canine movement, assessed using a synapse program on 3 digital panorex taken at the start of retraction and after retraction every 9 weeks. The rate of canine tooth movement was gathered at the end of phase 1 (week 3 - week 12 after start of orthodontic treatment), phase 2 (week 12 - week 12 after the start of orthodontic treatment) and over the total time (week 3 - week 21 after the start of the orthodontic treatment) | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Canine angulation change, measured using Panorex film taken at the week 3 and week 21 2. Pain level score after application of LED curing light, measured through self-reported pain raiting on the Numerical Rating Scale (NRS) (0 indicates "no pain", 1-3 indicates "mild pain", 4-6 indicates "moderate pain" and 7-10 indicates "severe pain") after every visit (weeks 0, 3, 6, 9, 12, 15 and 18) 3. Complications: 3.1. Tooth vitality, assessed using Electric Pulp Vitality Testing (EPT) at week 0 and week 21 3.2. Root resorption, assessed using parallel films at pre-treatment and post-treatment | — |
