23 Patients were instructed on how to safely place, use and remove the device and how to store and transport the device (Figure 2.4 A-D). The application of LED device was given to each patient in accordance with the manufacturer’s recommended LED device use of 21 minutes per day (i.e., one phototherapy cycle). This protocol was based on prior studies on the effect of low level laser therapy and on pilot studies by the manufacturer assessing the intra-alveolar light received from the current LED device. Therefore, patients were instructed to complete one LED cycle per day until their next orthodontic appointment (i.e. T1 or T2). Compliance was logged by the device’s controller. In addition, a manual record of LED use was also kept by each patient, using a paper calendar to document the days on which they completed an LED phototherapy cycle. The compliance rate for each patient in a given time period was calculated by dividing the number of days of LED use by the total prescribed days of LED phototherapy. 2.5 Data and Statistical Analysis For each patient the following data was collected: • Age • Sex • Wire size during the extraction space closure phase • Extraction space size at T0, T1, T2 • The side of the dental arch that received LED phototherapy • The number of days that the LED was used (device data log and paper calendar) • The number or days for each time period (T0T1) and (T1T2)
