Influence of infiltration technique and selected demineralization methods on the roughness of demineralized enamel: An in vitro study.

BACKGROUND: The decalcification of enamel leads to an increase in tissue roughness. The development of carious lesions may be halted or these lesions may heal, which results in a smoother surface. OBJECTIVES: The objective of the study was to assess the impact of selected agents on the roughness of demineralized enamel on the smooth surfaces of teeth. MATERIAL AND METHODS: A total of 25 samples with exposed enamel surfaces were examined in the study. The samples were randomized into groups and they were exposed to a demineralizing solution, after which the following agents were applied: Icon (Ic), Elmex gel (El), GC Tooth Mousse (TM), Colgate Total (K+) - a positive control group, and distilled water as a negative control group (K-). The impact of selected agents on the roughness of demineralized enamel was assessed with a profilometer. The parameters Ra, Rz and Rq were analyzed. RESULTS: Following infiltration and demineralization, the Ra coefficient declined in groups Ic, TM, K+ and K-, Rz decreased in groups Ic, TM and Rq was lower in groups Ic, TM and Kafter using agents when compared with demineralization. The lowest Ra, Rz and Rq values, i.e. the highest degree of surface smoothness, were observed in group Ic. An increase in all coefficients (Ra, Rz and Rq) was noted in group El. CONCLUSIONS: Demineralized enamel can be smoothed out through the one-time application of Icon resin or the long-term application of GC Tooth Mousse. The least effective agents turned out to be those with a high fluoride content.
