Composite Repair Using Silane Coupling Agent
Sponsor: Cairo University
Summary
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.

Conditions
Interventions
Silane coupling agent
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
