Several different methods are currently being implemented to determine the microleakage. Our method, utilizes the molecular characteristics of the methylene blue in which pH adjusted to 6.98, and the surface area covered by the methylene blue dye adsorbed in the areas where leakages have occured subsequent to the thermal conversion similar to the traditional methods. Within the framework of this study, 20 primary molars were divided into two groups, and restorations were made in one group with the glass ionomer cement plus amalgam while the other group of teeth was treated with glass ionomer cement and composite. These two groups were evaluated for surface area measurements using the Mann-Whitney U test with SPSS 10.0 statistical package, and were found to be statisticaly different (p<0.001). It is therefore concluded that this method may be used as a new technique for the determination of microleakage and that it may even be further developed.eninfo:eu-repo/semantics/openAccessArticle1911811872-s2.0-1384429701410.1080/13102818.2005.10817178N/A
