White-spot lesions, Dental caries, Ahesive dental coating


Introduction: the treatment of early proximal carious lesions represents a challenge to modern conceptions of cariology and operative dentistry. The possible solutions include, besides an early diagnosis, development of new materials to control early caries progression. The objective of this in vitro study was to evaluate the degree of penetration of three adhesives: Excite (Ivoclar-Vivadent), Prime & Bond NT (Dentsply), and Single Bond (3M-ESPE), in the process of sealing white-spot non-cavitated proximal lesions. Methods: 117 extracted human premolars with ICDAS 2 white-spot non-cavitated proximal lesions mounted on plaster, to simulate oral cavity conditions, were randomly sorted out in each of the three groups. The lesions were sealed with each of the materials previously mixed with methylene blue; longitudinal sections of 250 µm were obtained, and they were later analyzed on photographs taken with a stereo microscope. These variables were evaluated: total lesion coating, lesion’s histologic depth (in micrometers), and the adhesive’s maximum penetration. Results: a total of 116 teeth were analyzed. Entire lesion coating was found in 52.5% of the cases; 75% were located in the enamel’s internal half, with an average depth of 854 ± 493 μm. The adhesive’s maximum average lesion penetration was 697 ± 412 μm. No statistical significant differences were found among the groups (Kruskal Wallis and Spearman correlation; p > 0.05). Conclusion: these three low-viscosity adhesives with high amounts of TEGDMA and HEMA effectively achieved covering and penetrating of the material for sealing early proximal carious lesions.
