“…Microleakage is determined today by many in vitro techniques with or without thermal cycling, such as staining, scanning electron microscope, bacterial activity, decay, air pressure, chemical agents, markers, neutron activation analysis, radioisotope, ionization, autoradiography and reversible radioactive adsorption 17 . In this study, the dye leakage method was used because it is a simple, inexpensive, fast technique and does not require the use of complex laboratory equipments 13 .…”

The aim of this study was to quantify the marginal leakage of two glass-ionomer cements using spectrophotometer. Method and materials: Standardized class V cavities were prepared on 60 extracted human maxillary permanent first premolars, randomly assigned to two groups of 30 teeth each, group A and group B. Group A was restored with Zirconomer and group B was restored with GC Fuji IX Extra. Teeth were subjected to thermocycling and stained with methylene blue. The microleakage was quantified spectrophotometrically and the data were statistically analyzed with Student t test. Results: Restorations of both the materials showed some microeakage in Class V cavities and there were no significant differences statistically. Conclusion: The sealing ability of GC Fuji IX Extra was much better than Zirconomer and GC Fuji IX Extra exhibit better shade matching compared to Zirconomer at cervical area of the teeth.

“…Another important issue in the microleakage studies arises from the scoring systems. Since the evaluation in these studies largely depends on the observer's interpretation, the leakage scoring is at best a semi-measurable tecnique (4,5,6,7,8,29,33,34).…”

This study was planned to investigate the feasibility of a different approach as an alternative to the methods for determining the microleakages caused by the dental restorations. 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.

“…2% methylene blue dye for 24 hours. (15) After removal from the dye solution, they were cleaned and rinsed with tap water. The teeth were embedded in selfcuring acrylic resin to prevent chipping of the material and the resin blocks were sectioned with a cut buccolingually and parallel to the long axis, into two fragments using diamond disk for sectioning (Germany).…”

Aim of the study: To evaluate in vitro the microleakage of fissure sealant, the effect of using home bleaching agent containing 18% carbamide peroxide and the effect of ethanol as an antioxidant agent on microleakage. Materials and Methods: Twenty four extracted sound human third molars were randomly assigned to 3 groups. After sealant placement, the teeth were thermocycled (125 cycles; 5-55°C), isolated, immersed in 0.2% methylene blue dye for 24 hours, included in acrylic resin and sectioned longitudinally in a buccolingual direction. The sections were analyzed for leakage using an stereomicroscope, and a 4-criteria ranked scale was used to score dye penetration. Results: Microleakage scores increased with significant difference between control and bleached group when home bleach was used for fourteen days, also leakage scores decreased with significant difference when ethanol was used after bleaching to reverse the oxidation process, no significant difference was observed between control versus ethanol group. Conclusions: Microleakage scores increased after bleaching because of reduction in enamel bond strength of sealant when the bonding procedure was carried out immediately after bleaching, use of ethanol or other types of antioxidant reduced the amount of microleakage significantly.
