title: [Assessment of microleakage of adhesive restorative materials in deciduous teeth].
abstract: The microleakage of Chelon-Fil, Vitremer, Compoglass-F and Z100 was evaluated in deciduous teeth. Class V restorations were placed in the buccal aspect of 40 extracted primary canines; they were thermocycled, and immersed in 0.5% basic fuchsin. Three slices of each tooth were obtained in order to analyze the penetration of dye in the gingival and occlusal walls, under magnification of 40 X. The results showed that Chelon-Fil had the highest degree of marginal leakage. Vitremer, Compoglass-F and Z100 presented similar penetration of dye. The microleakage of Chelon-Fil and Vitremer was greater in the gingival wall than in the occlusal wall. Microleakage was the same in both gingival and occlusal walls when cavities were filled, either with Z100 or with Compoglass-F.
