Since the effectiveness of occlusal sealing is related to proper seal of the surface, a higher wettability of the sealant would assist in their scattering and avoid the bubble formation, allowing greater adhesion to the enamel structure. So, this study aimed to evaluate the wettability of different resinous sealants front of the smooth and rough glass. The sealants used were: Fluorshield, Helioseal Clear and Defense Chroma Angie. The material wettability was measured by contact angle (sessile drop), using Digidrop goniometer and considering the following groups: 1. Smooth surface; 2. Rough surface of a glass slide. Data were submitted to factorial ANOVA (material x surface) and Tukey's test (p<0.05), using Assistat 7.7 software. There was significant interaction between the materials and surfaces studied (p<0.01). The Helioseal Clear sealant showed the highest wettability on rough glass. Fluorshield and Defense Chroma Angie sealants when applied on smooth glass surface showed lower wettability. Therefore, different sealants exhibit different wettability levels and the type of surface affect this property. The higher wettability was found in the Helioseal Clear sealant when applied onto the rough surface of a glass slide.
