| Low level laser therapy | Radiation | The low-level laser applied will be a Diode laser* emitting infrared radiation at a wavelength of 980 nm, in a continuous mode. On the experimental side, subjects will receive LLLT on days 0, 3, 7, 14, and every 2 weeks thereafter, till the termination of the study period (3 months). |
| Measure | Description | Time Frame |
|---|---|---|
| Measurement of alveolar bone density | Bone density will be measured from cone beam computed tomography (CBCT) scans at 2 different locations on each side of the upper arch; between the canine and lateral incisor, and between the canine and second premolar. Bone density will be measured using Hounsfield Units (HU). | 3 months |
| Measurement of alveolar bone microstructure | From the CBCT scans, the maxillary alveolar process between the canine and lateral incisor, and between the canine and second premolar will be examined. Bone microstructures will be measured and calculated with a dedicated software. | 3 months |
| Measurement of buccal bone thickness | buccal bone thickness will be measured from the CBCT scans. Three points will be measured from the buccal bone to the root, at the coronal, mid-root, and apical level | 3 months |
| Measurement of alveolar bone volume | From CBCT scans, bone volume in areas of the maxillary alveolar process between the canine and lateral incisor, and between the canine and second premolar will be measured | 3 months |
| Measurement of bone Microstructure | Using the collected CBCT scans, the region of interest will be selected within the maxillary alveolar process, and fractal dimension analysis will be performed using a special software. | 3 months |
