Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Evaluation the influence of the use of silane coupling agent application as a separate step versus application of silane or acid resistance silane containing adhesives on the clinical performance of repaired posterior resin composite restorations according to Modified United States Public Health Service (USPHS) criteria over one year.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

some manufacturers have produced silane-containing adhesives in their new products, which might eliminate the need to apply separate silane. However, this silane coupling agent can be hydrolyzed by the acidic monomer in the adhesive making it useless. Acid resistance silane containing adhesive is the update version of the silane containing adhesive which provides a long lasting effective bond between the old and new resin composite restorations

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Silane coupling agent(Comparator)

In the control group, Silane coupling agent (Porcelain primer) will be applied following the acid etch rinsing and drying step, for 30 seconds and then it will be thoroughly dried using air syringe then universal adhesive with regular silane will be actively applied for 20 seconds and then it will be light cured for 20 seconds and final restoration will be done.

.Adhesive containing silane.(Intervention 1 )

Universal adhesive with regular silane will be applied for 20 seconds, air thinned for 10 seconds and then it will be light cured for 20 seconds and final restoration will be done using same resin composite material

Acid resistance silane containing adhesive.(Intervention 2)

Acid resistance silane containing adhesive will be applied for 20 seconds, dry with gentle air for 3 seconds, then with stronger air and light cured for 10 seconds and final restoration will be done
