Deep Margin Elevation With Different Restorative Materials in Class II Resin Composite
Study Details
Study Description
Brief Summary
This study was designed to evaluate and compare the 2-year clinical performance of resin composite restorations in class II cavities with deep sub-gingival margins relocated using three different glass ionomer based restorative materials and flowable composite, based on FDI criteria.

Detailed Description
The description of the experimental design followed the Consolidated Standards of Reporting Trials (CONSORT) statement. The present study was a double-blinded (patients and examiner) randomized clinical trial anticipating the parallel design. One hundred and twenty adult patients seeking dental treatment in Operative Department clinic at Faculty of Dentistry, University of Mansoura were enrolled in the current study with a total of 120 Class II restorations. No advertisement was made for participant recruitment, forming a sample of convenience. Each patient much sign a consent form before participating in the current study. The study was conducted from January 2020 to January 2022 as a part of Doctoral dissertation. Mansoura University institution's ethics committee approved the form and protocol before conducting the study. The sample size was calculated based on the clinical success rate (100% success rate at 2 years) of posterior class II restorations restored with open sandwich and deep margin elevation techniques observed in previous studies. According to several parameters including a significance level of 5%, the power of the test was calculated to be 80%, and equivalent limit of 15%. Upon these data, a sample size of 120 subjects was appropriate. Allowing for a 20% drop-out, sample size was set totalizing 120 subjects.

Outcome Measures
Primary Outcome Measures
- Percentage of patients with periodontal problems [2 years after restoration]
The periodontal situation of patients were examined based on bleeding on probing, plaque index and probing depth scores
- Percentage of aesthetic, functional and biological properties for each base material restorations [2 years after restoration]
Percentage of aesthetic, functional and biological properties were clinically assessed using World Dental Federation parameters for each base material group
Secondary Outcome Measures
- Radio graphic examination [2 years after restoration]
Each base material/gingival dentin interface was examined radio graphically each 6 months period.
