WebMaterial and Methods: This was an in vitro intergroup comparative study, which consisted of 2 groups- Group I (Conventional acid etch sealant, Clinpro) and Group II (Self etching sealant, Prevent Seal). Out of 32 selected teeth 16 were used to study microleakage, with the help of dye penetration test using {\"o}vreb{\"o} and Raadal criteria. WebDye Liquid Test (DPT) is one of one simple and oldest Non-Destructive Inspection methods. Also, known how the Solid penetration test, the Dye penetrant test is widely previously to detect surface discontinuities like cracks, fractures, porosity, grinding defects, incomplete meld, and flaws include joints.

Penetrant dwell time is the total time that the penetrant is in contact with the part surface. The dwell time is important because it allows the penetrant the time necessary to seep or be drawn into a defect. Dwell times are usually recommended by the penetrant producers or required by the specification being followed.
