Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Materials and Methods : 45 patients were recruited for this study from patients attending the restorative dentistry clinics for postgraduate students, Jordan University of Science and Technology. Each patient had at least two defected posterior composite restorations that are indicated for repair. With this selection, 116 restorations with localized anatomical deficiencies and/or secondary caries were randomly assigned into three groups according to the type of surface treatment each tooth will receive before the application of the new composite material (Filtek Z250,3M,USA). The teeth in the control group (n = 45): were treated with 37% phosphoric acid etching and conventional one step adhesive (Single Bond,3M,USA). In the Silane-Adhesive group (n = 26): teeth were treated with acid etching and silane coupling agent application (Bis-silane) prior to adhesive bond (Adper single bond). In the Sandblast-Silane-Adhesive group (n = 45): teeth were treated with intra-oral sandblasting and silane coupling agent application (Bis-silane) prior to (Adper Single Bond). The reason of repair, age of old restorations and the location of the restoration-repair interfaces were recorded for every failed restorations. Two examiners followed-up and evaluated the restoration quality after an average of 6 months using modified USPHS criteria. The results of clinical performance were assessed using Chi-square test.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control: traditional acid etch treatment group
Traditional acid etching to the tooth and old restoration surfaces and then adhesive application.
composite restoration repair by traditional acid etch treatment procedure and adhesive.
Recurrent caries surrounding the defective restoration was removed and the surfaces were coditoned with acid and adhesive then new repair composite was addded to repair the old restoration and restore the carious cavity.
Silane-Adhesive treatment group
Acid cid etching of prepared tooth tissues and old restoration surfaces, silane solution application, and then adhesive application.
Composite restoration repair by acid etching, silane solution application, and then adhesive.
Recurrent caries surrounding the defective restoration was removed and the surfaces were coditoned with acid, then silane applied, next adhesive then new repair composite was addded to repair the old restoration and restore the carious cavity.
Sandblast-Silane-Adhesive treatment group
First sandblasting the old composite filling surfaces, then acid etching of prepared tooth tissues the restoration, then silane application followed by adhesive application.
Composite restoration repair by sandblasting first, then acid etching, silane solution application, and then adhesive.
Recurrent caries surrounding the defective restoration was removed, the old restoration surface were sandblasted, and the tooth and restoration surfaces were coditoned with acid, then silane applied, next adhesive then new repair composite was added to repair the old restoration and restore the carious cavity.
