INTERVENTIONAL
Conditions
Summary
The aim of this study is to investigate the effects of photobiomodulation therapy (PBM) on the dental and periodontal health of patients undergoing fixed-appliance orthodontic treatment, including orthodontically induced root resorption, orthodontic pain, space closing rate, and dental microbiome profile in dental plaques.
Eligibility
Inclusion Criteria5
- Patients aged between 18 and 35 years old with permanent dentition
- Patients who undertake orthodontic treatment using fixed appliances
- Patients who require extraction of premolars in either their upper or lower dental arch
- Patients who have fair oral hygiene habits
- Patients who are systemically healthy
Exclusion Criteria5
- Patients with generalized dental caries and severe chronic periodontitis in stages III and IV
- Patients with congenital or severe craniofacial anomalies which necessitate orthognathic surgery
- Patients with physical or mental impairment, and those who smoke or undertake systemic medications
- Patients with current root resorption at any of the teeth
- Patients with endodontic treatment and/or large restorations on premolars to be extracted

Interventions
Patients in the PBM group will be delivered a portable PBM device (PBM Healing Ortho) at the beginning of orthodontic treatment and will be instructed to use it daily at home for 8 minutes (4 min per arch) after tooth brushing.
All eligible patients will receive orthodontic treatment with a pre-adjusted fixed appliance (0.022'' × 0.028'' slot system, MBT, 3M Unitek) provided by the same practitioner. At the start of treatment, a cantilever auxiliary arch bent with a 0.017'' × 0.025'' Stainless Steel wire (3M Unitek) will be used to apply a 100 g intrusion force to the premolars that will be extracted in 3 months. All other teeth will undergo regular orthodontic treatment with a standard archwire protocol (0.014'' NiTi, 0.016'' NiTi, 0.018'' NiTi, 0.017'' × 0.025'' NiTi, 0.019'' × 0.025'' NiTi, and 0.019'' × 0.025'' SS, 0.019'' × 0.025'' TMA) for alignment, leveling, space closure, detailing, and finishing. For en masse retraction, a 150 g force will be applied by coil springs, allowing bracket slots to slide along the 0.019'' × 0.025'' SS.
