Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Marginal adaptation

    Alpha (A) Restoration adapts closely to the tooth structure; there is no visible crevice Bravo (B) There is a visible crevice, the explorer will penetrate, without dentin exposure. Charlie(C) The explorer penetrates into a crevice in which dentin or the base is exposed.

    T0= Baseline 24 hours postoperative. T1= 6 months follow up. T2= 12 months follow up.

Secondary Outcomes (5)

  • Anatomical form

    T0= Baseline 24 hours postoperative. T1= 6 months follow up. T2= 12 months follow up.

  • Marginal discoloration

    T0= Baseline 24 hours postoperative. T1= 6 months follow up. T2= 12 months follow up.

  • Surface roughness

    T0= Baseline 24 hours postoperative. T1= 6 months follow up. T2= 12 months follow up.

  • Secondary caries

    T0= Baseline 24 hours postoperative. T1= 6 months follow up. T2= 12 months follow up.

  • Postoperative sensitivity

    T0= Baseline 24 hours postoperative. T1= 6 months follow up. T2= 12 months follow up

Study Arms (3)

Silane coupling agent(Comparator)

ACTIVE 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.

Other: Silane coupling agent

.Adhesive containing silane.(Intervention 1 )

ACTIVE COMPARATOR

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

Other: Adhesive containing silane.(Intervention 1 )

Acid resistance silane containing adhesive.(Intervention 2)

ACTIVE COMPARATOR

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

Other: Acid resistance silane containing adhesive.(Intervention 2)
