Resumen

It is a known fact that there is a relationship between magnitude of bonded area and laboratory tensile test results. This relationship has been described for a range of areas between 1 and 100 mm2, in extracted, nonperfused teeth. The aim of this study is to test this relationship in perfused teeth, with bonden areas ranging from 0.7 to 110.9 mm2. Dentin of 92 sound third human molars was exposed and perfused, and three groups of bonden areas (BA) were delimited: small (0.69-1.89 mm2), medium (8.66-19.54 mm2), and large (58.91-110.86 mm2). Tensile bond strength (TBS) of three adhesive restorative systems was found. The best nonlinear curve estimation was searched (SPSS 9.0) between TBS and BA, for each and all materials. The best estimation was, for all materials, TBS = 4.17 + 10.35/BA (p minor to 0.0001)
