Evaluation of Prevention of Initial Enamel Lesions around Orthodontic Brackets by Using Different Remineralizing Agents: An Original Research

The purpose of this study was to compare the efficacy of various remineralizing agents in stopping the early enamel lesions surrounding orthodontic brackets from progressing.

Four groups were randomly allocated to a total of 100 participants: the control group (no treatment), calcium phosphate, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), and fluoride varnish. Remineralizing chemicals were administered in accordance with manufacturer recommendations, and enamel lesions were created around orthodontic brackets. At baseline and follow-up visits, enamel lesion development was evaluated by visual inspection, quantitative light-induced fluorescence, and microhardness tests.

All treatment groups showed significant improvements in microhardness and decreases in lesion size compared to the control group (P < 0.05). Of all the treatment groups, CPP-ACP showed the most notable improvement in microhardness. Regarding the reduction of lesion size, there were no notable variations between the therapy groups (P > 0.05).

Initial enamel lesions surrounding orthodontic brackets can be effectively prevented from progressing with the use of fluoride varnish, calcium phosphate, and CPP-ACP. Promising improvements in microhardness indicate that CPP-ACP may be a better treatment choice. Larger sample sizes and longer follow-up times are needed for future studies to validate these results and clarify the best strategy for maintaining the health of enamel throughout orthodontic treatment.
