Remineralization properties of 2 orthodontic primers
Researchers have compared the efficacy of two orthodontic primers.
In a study published in the Journal of Dentistry, the researchers used field emission scanning electron microscopy and energy dispersive X-ray spectroscopy to evaluate the demineralization resistance, length of the antidemineralized zone surrounding the orthodontic bracket, and remineralization properties of graphene/hydroxyapatite and graphite fluoride/bioactive glass primers.
The researchers found that there was a homogenous distribution with calcium and fluorine without agglomeration, a notable expansion in the antidemineralization zone as well as high levels of calcium and phosphate ions — lasting up to 112 and 168 days in the graphene/hydroxyapatite primer and graphite fluoride/bioactive glass primer, respectively. Further, after performing pH cycling to create white spot lesions on the teeth included in the study, the researchers noted maintenance of the mineral content with the graphite fluoride/bioactive glass primer followed by the graphene/hydroxyapatite primer.
The findings indicated that the remineralization effects of both primers may be favorable.
