NCT ID: NCT05500430 Completed - Repair Clinical Trials

Evaluation of Air Abrasion Surface Pretreatment in the Repairing Capacity of Defective Composite Restoration

Start date: January 20, 2022
Phase: N/A
Study type: Interventional

This study is conducted to compare the efficacy of surface pretreatment using air abrasion sandblasting aluminum oxide particles (Al2O3) versus not pretreatment in the repair capacity of defective composite restoration indicated for repair.

NCT ID: NCT03214445 Completed - Dental Caries Clinical Trials

Sealing Defective Margins of Composite Restorations With Fluid Composite Resin Nanofiller Reinforced

SEAL2
Start date: March 1, 2015
Phase: N/A
Study type: Interventional

the patient (n=60), with at least 3 composite resins with marginal defects , randomized into 3 groups A=Sealed with flow composite reinforced with nanofiller , B= Sealed with resin sealant , and C=Control, without intervention , and then assessed by the FDI criteria for clinical performance and longevity of restorations

NCT ID: NCT02043873 Completed - Replacement Clinical Trials

Can Repair Increase the Useful Life of Composite Resins?

REPCOMP
Start date: August 2003
Phase: N/A
Study type: Observational

Objectives: The aim of this prospective, randomized, triple-blind cohort study was to assess the longevity of repairs to localized clinical defects in composite restorations that were initially scheduled to be treated with a restoration replacement Methods: 28 patients aged 18 to 80 years with 50 composite restorations were recruited.Restorations with clinically diagnosed secondary caries (Charlie) or undercontoured anatomical form defects (Bravo) were randomly assigned to the Repair (n = 25) or Replacement (n = 25) group, the quality of the restorations was scored according to the modified USPHS criteria. A Wilcoxon test was performed for comparisons between the same groups (CI=0.05). A Friedman test was utilized for multiple comparisons between different years of the same group.
