Evaluation of Using Self-adhering Flowable Resin Composite Versus Conventional Nano-filled Flowable Resin Composite in Repairing Old Defective Resin Composite Restorations Over 18 Months Follow up. (A Randomized Clinical Trial)

This research proposal is evaluating the clinical performance of using self-adhering flowable resin composite in repairing old occlusal defective resin composite versus conventional flowable resin composite restoration over 18 months.

Inclusion Criteria:

• Patients (18-35 y)
• patients with defective resin composite class I restorations that need repair.
• dental motivated patients who attends regularly.
• Vital posterior teeth with repairable defective resin composite class I restorations.
• Localized marginal defect or marginal staining FDI 3& 4.
• Teeth with no or minimum mobility & healthy peridontium.
• No history of any irreversible pulpal pain or necrosis in the teeth to be restored.

Exclusion Criteria:

• • Patients with defective restorations that dictate replacement

  • Uncooperative behavior limits the isolation techniques throughout the procedure.
  • Presence of parafunctional habits.
  • Patient with history of systemic medical disease, or any other serious relevant problem.
  • High caries risk patients. Periodontal disease that may affect the prognosis of the restoration or the tooth itself.
  • Fractured or visibly cracked teeth.
  • Symptoms of any pulp pathosis.
  • Defective resin composite restorations that dictate replacement.
