EFFECT OF CASEIN PHOSPHOPEPTIDE AMORPHOUS CALCIUM FLUORIDE PHOSPHATE VARNISH ON WHITE SPOT LESIONS AND SHEAR BOND STRENGTH OF ORTHODONTIC COMPOSITE: AN IN-VITRO STUDY

Introduction: Notwithstanding progress in caries prevention methods, avertingenamel demineralization during orthodontic treatment remains a significant challengefor clinicians. Orthodontic treatment primarily aims to improve both dental andfacial aesthetics, yet protecting the enamel from demineralization continues to be acritical concern. Aim: This research aims to assess the enhancements that occurredaround orthodontic brackets as a result of the application of Casein PhosphopeptideAmorphous Calcium Fluoride Phosphate (CPP-ACFP) varnish, as well as to investigatethe impact that this varnish had on the shear bond strength of orthodontic composite.Materials and Methods: For the purpose of this in vitro experiment, enamel specimenswere randomly assigned to two primary groups, with each group consisting of twentyspecimens. The groups were determined by the surface treatment that was applied to theenamel. In Group I, which served as the control group, there was no surface treatmentapplied, but in Group II, the surface was treated with CPP-ACFP varnish. After then,each group was divided into two subgroups, each of which contained ten specimens.Subgroup A was subjected to a pH cycling procedure, whilst Subgroup B was immersedin a Streptococcus mutans suspension. Results: CPP-ACFP varnish groups showedthe greatest resistance to discoloration represented by the least color change withoutsignificant effect on shear bond strength. Conclusions: Using CPP-ACFP varnish inorthodontic treatment demonstrates potential benefits specifically in reducing whitespot lesions and maintaining bond strength.
