U.S., Aug. 7 -- ClinicalTrials.gov registry received information related to the study (NCT07105969) titled 'Strontium-Hydroxyapatite Coated Mini-Screws: Antibacterial Effect and Stability' on June 30.
Brief Summary: This randomized controlled clinical trial aims to evaluate the antibacterial efficacy and stability of strontium-incorporated hydroxyapatite (Sr-HA) coated orthodontic mini-screws (OMSs) used for maxillary canine retraction. A double-blind, split-mouth design was employed, involving 20 patients (aged 16-20 years), each receiving two titanium alloy mini-screws (1.6 mm x 8 mm): one coated with Sr-HA (5% concentration via electrochemical deposition) and one uncoated control. A total of 40 mini-screws were assessed. Following upper...
