Sponsor

The University of Hong Kong

Enrollment

50 participants

Start Date

Jan 20, 2024

Study Type

INTERVENTIONAL

Conditions

orthodontics Root Resorption

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

Min Age: 18 YearsMax Age: 35 Years

Interventions

DEVICEphotobiomodulation therapy

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.

OTHERorthodontic fixed-appliance

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.
