title: Effect of mixing process on microleakage of glass ionomer cements used in atraumatic restorative treatment on primary molars.
abstract: Aiming to assess the effect of mixing process on microleakage, 40 primary molars were filled with encapsulated glass ionomer cements (GICs) (Vidrion, RCaps and Fuji, IXGPFAST) or with GICs stored in bottles (Vidrion, R and Fuji, IX). Dye penetration was assessed using scores. Encapsulation and mechanical mixing have reduced significantly marginal microleakage levels in class II restorations performed with conventional GICs if compared to the values obtained by their bottled correspondents (p=0.000).
