The rumors about @BALRdunno if true,but about cucundah i'd say some of them are. But is better with @Chukundahin game than without.
Enjoy the game boyz,the curse is real anyways.

Lets talk for real boyz. I'm courious what opinion has my fav dentist from Craiova city about microleak'
SHRINKAGE AS THE PREDICTOR OF MARGINAL DETERIORATION.[3.2] POLYMERIZATION Composite restorations are subjected to polymerization shrinkage which occurs due to affiliation of the resin molecules with one another and formation of chemical bonds which reduce the material sbulk[23]The C-factor plays an major role in determining the amount of shrinkage. C factor is defined as the ratio between the bonded and unbounded cavity surfaces. Increasing this ratio also increases the stress from polymerization shrinkage.[24]Shrinkage of composites results in stresses, cuspal deflection which inturn leads to enamel cracks, hypersensitivity, marginal degradation, microleakage. It also includes potential debonding of the tooth composite interface.[25]The amount of shrinkage and stresses varies with the composite filling material used.[26][27].It is influenced by material flow, chemistry, curing dynamics and the size and shape of the preparation, hygroscopic expansion. The intensity and duration of curing have been found to affect polymerization.[28] Polmerization shrinkage stress of composite resin is about 13-17MPa.Therefore adhesive agents should have a good bond strength higher than this amount.[29][30]Polymerization shrinkage of composites can lead to microleakage which can cause an immediate inflammatory reaction in pulp.[31][32][33].Three different strategies to reduce polymerization stress includes modification to placement technique, altered curing schemes, use of a resilient liner on dentin.[34][35]
