- Primary Outcome Measures
Name Time Method 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 Outcome Measures
Name Time Method <br> 1. Canine angulation change, measured using Panorex film taken at the week 3 and week 21<br> 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)<br> 3. Complications:<br> 3.1. Tooth vitality, assessed using Electric Pulp Vitality Testing (EPT) at week 0 and week 21<br> 3.2. Root resorption, assessed using parallel films at pre-treatment and post-treatment<br>
