Resumen
This in vitro study compared microleakage along the dentin-restorative interface using a spectrophotometer protocol and two conventional single-surface methods (scores and percentages), using an organic dye (0.5% buffered methylene blue) or a tracer (50% silver nitrate). Occluso-proximal preparations with gingival margins in dentin were made in 40 human teeth. The teeth were divided into four groups (n = 10) according to the solution dyes and adhesive system used: group 1, single bond/methylene blue; group 2, single bond/silver nitrate; group 3, Clearfil SE Bond/methylene blue; and group 4, Clearfil SE Bond/silver nitrate. The dye penetration measurements were made in all groups, using scores and percentages. Groups 1 and 3 were also assessed by UV spectrophotometer. For percentage measurement, the data were submitted to ANOVA and Tukey's test. For the material factor, there was a statistically significant difference between groups 1 and 3. For the dye factor, there was a statistically significant difference between groups 3 and 4. The score results were submitted to Kruskall-Wallis test and showed differences between groups 1 and 3 and groups 2 and 3. For spectrophotometer measurement, no significant difference was observed between groups 1 and 3. The results of dye penetration suggest that there was a difference between dyes and measurement methods, and this should change the interpretation of microleakage tests. © Springer-Verlag 2006. 10 4 317 323 Alani, A.H., Toh, C.G., Detection of microleakage around dental restorations: A review (1997) Oper Dent, 22, pp. 173-185 Alonso, R.C., Cunha, L.G., Correr, G.M., De Goes, M.F., Correr-Sobrinho, L., Puppin-Rontani, R.M., Sinhoreti, M.A., Association of photoactivation methods and low modulus liners on marginal adaptation of composite restorations (2004) Acta Odontol Scand, 62, pp. 298-304 Arrais, C.A., Giannini, M., Morphology and thickness of the diffusion of resin through demineralized or unconditioned dentinal matrix (2002) Pesqui Odontol Bras, 16, pp. 115-120 Camargo, D.A., Sinhoreti, M.A., Consani, S., Sobrinho, L.C., In vitro evaluation of marginal leakage on class II composite restorations (2002) Braz J Oral Sci, 1, pp. 84-88 Camargo, D.A., Sinhoreti, M.A., In vitro evaluation of the penetration capacity of dyes and tracers used in microleakage studies (2002) J Dent Res, 81 (SPEC.
