Abstract

Objective: The aim of this study was to evaluate the effect of different remineralization agents-Proshield Fluoride Varnish (FV), GC MI Varnish (MI), and ROCS Medical Mineral Gel (ROCS MMG)-on the shear bond strength (SBS) of orthodontic brackets after application at various time intervals.

Methods: A total of 120 human premolar teeth were divided into 10 groups (n = 12). The experimental groups received different remineralization agents (FV, MI, ROCS MMG) at time intervals of 1, 15, and 30 days, while the control group received no application. The enamel surfaces were etched, and metal orthodontic brackets were bonded using a light-cured composite adhesive. SBS was measured using a universal testing machine, and adhesive remnant index (ARI) scores were assessed after bracket debonding.

Results: No statistically significant differences were observed in SBS among all experimental groups and the control group (P = 0.307). SBS values for the FV, MI, and ROCS MMG groups did not differ significantly at the 1, 15, or 30-day intervals. ARI scores also showed no significant differences between groups (P = 0.370).

Conclusion: The application of Proshield Fluoride Varnish, GC MI Varnish, and ROCS Medical Mineral Gel at different time intervals did not affect the shear bond strength of orthodontic brackets. These remineralization agents can be safely used to prevent white spot lesions and caries before orthodontic treatment at time intervals of 1, 15, and 30 days without compromising bond strength.

Clinical relevance: Proshield FV, GC MI Varnish, and ROCS MMG safely prevent white spot lesions and caries without affecting bracket bond strength.

期刊介绍： The journal Clinical Oral Investigations is a multidisciplinary, international forum for publication of research from all fields of oral medicine. The journal publishes original scientific articles and invited reviews which provide up-to-date results of basic and clinical studies in oral and maxillofacial science and medicine. The aim is to clarify the relevance of new results to modern practice, for an international readership. Coverage includes maxillofacial and oral surgery, prosthetics and restorative dentistry, operative dentistry, endodontics, periodontology, orthodontics, dental materials science, clinical trials, epidemiology, pedodontics, oral implant, preventive dentistiry, oral pathology, oral basic sciences and more.
