Orthodontic adhesives containing bioactive glass (BAG) particles/nanoparticles (including Ag-, Zn-, fluoride-, or Ga-doped BAG) vs Conventional/control orthodontic adhesive (e.g., Transbond XT) or negative control

In vitro, most bioactive glass-containing orthodontic adhesives (9 of 13 studies) showed significant enamel remineralization/anti-demineralization versus control, but the evidence is weak (predominantly high risk of bias, methodological heterogeneity, no meta-analysis; ungraded).
