The article presents a study to evaluate two techniques in posterior resin placement for their abilities to persist microleakage when the floor of the preparation is below the cementoenamel junction. In the study, extracted human premolars were used. Teeth were found to be free of caries, restorations and enamel defects after inspection. Teeth were divided into two groups for restoration. In the one group the liner was used to cover all the cut dentin. While in the second group a small amount of cut dentin was left exposed at the gingival floor.

    We investigated the bond strength between restorative resin and dentin pre-treated with mixtures of HEMA and glutaraldehyde. It is suggested that the mixture acts by forming a chemical bond of HEMA molecules to a collagen-glutaraldehyde reaction complex. Subsequently applied resin will then...
