Sellado marginal en esmalte dental en cavidades Clase I obturadas con materiales de obturación provisional. Estudio in vitro

Abstract

Provisional fillings protect the coronary tooth remnant for a short period of time (between one appointment and another), while permanently sealing. Microfiltration is the passage of bacteria, fluids and molecules between the cavity wall and the restorative of the material placed in it, which could cause post-operative sensitivity, risk in the development of recurrent caries and pulpal pathologies. The objective of this investigation was to evaluate the marginal microfiltration in class I cavities filled with three provisional obturation materials that were submitted to methylene blue nitrate stain 0.45 gr / ml and some to the thermocycling process. The test of the median x 2 p = .0062 implies significant differences between the materials used. x 2 = 0006 for microfiltration in dentinal tubules implies significant differences between methods 1 (Cinquenol) method 2 (Coltosol F) and 3 (Clip F). The result obtained with the Kruskal-Wallis H test p = 0.0049 8.00, implies that methods 2 and 3, are those that have lower penetration of the dye at the level of the dentinal tubules, following the method 1.
