Research on Treating Demineralized Enamel with Different Remineralizing Agents before Bonding Orthodontic Brackets

Many orthodontic clinics have problems with patients who have dental demineralization. This study aimed to evaluate "the shear bond strength (SBS)" of braces after being bonded to demineralized teeth treated with herbal materials. Our study samples were divided into five groups. The first group was left with no treatment. The surfaces of the second, third, and fourth groups were first treated with a demineralizing solution. The second group was left after being demineralized without any subsequent treatment; the third group was treated with rosemary oil; the fourth was treated with ginger-honey. Casein phosphopeptide-amorphous calcium phosphate with fluoride paste (CPP-ACPF) was applied to the fifth group. A universal testing machine evaluated the SBS. A stereomicroscope was used to determine the adhesive remnant index (ARI). The enamel surface changes were observed using surface microhardness (SMH) testing, scanning electron microscopy (SEM), and energy dispersive spectrometry (EDS) to determine the element percentages. Our data revealed that the values of both SBS and SMH were significantly (p < 0.05) increased after remineralization. Rosemary and ginger-honey significantly enhanced the SBS and SMH of the demineralized teeth.
