CLINICAL COMPARISON OF DIFFERENT GLASS IONOMER-BASED RESTORATIVES AND A BULK-FILL RESIN COMPOSITE IN CLASS I CAVITIES: A 48-MONTH RANDOMIZED SPLIT-MOUTH CONTROLLED TRIAL
A study testing class I restoration placement in people with Class I Dental Caries, run by Hacettepe University at 1 site in Turkey (Türkiye).
Trial summary
The aim of this study is to compare the clinical performances of high-viscosity glass ionomer (GI), glass carbomer (GC), zirconia-reinforced GI (ZIR), and bulk-fill (BF) composite resin restorations.For this purpose, two calibrated operators placed 128 restorations in 30 patients with a mean age of 21 years.

About this study
The aim of this study is to compare the clinical performances of high-viscosity glass ionomer (GI), glass carbomer (GC), zirconia-reinforced GI (ZIR), and bulk-fill (BF) composite resin restorations.For this purpose, two calibrated operators placed 128 restorations in 30 patients with a mean age of 21 years. The restorations will be evaluated by one examiner at baseline and at 6, 12, 18,24, and 48 months using the modified US Public Health Service criteria. The data will statistically analyzed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
class I restoration placementProcedure or surgery
zirconomer, glass carbomer, glass ionomer and composite resin class I restorations were placed.
| Study group | Role | What they receive |
|---|---|---|
| zirconomer | Active comparator | zirconia reinforced glass ionomer cement Receives: Procedure: class I restoration placement |
| Equia Fil | Active comparator | High viscosity glass ionomer cement Receives: Procedure: class I restoration placement |
| glass carbomer | Active comparator | glass ionomer cement containing nano sized- carbonized particles. Receives: Procedure: class I restoration placement |
| Tetric-evo ceram bulk fill | Active comparator | Bulk fill composite resin Receives: Procedure: class I restoration placement |
What is being measured
The primary outcome is the main question the study is designed to answer.
Retention Alpha for at least 90% of the restorations
The primary factor for determining the clinical performance of a restorative material is the retention rate. It represents the survival rates of the restorations after a period of time. According to ADA guidelines, a restorative material should show at leat 90% alpha retention rate after 18 months to be considered as clinically acceptable. The retention is assesed as alpha (retentive restoratation) or charlie (failed restoration). Clinical evaluation is performed to examine if the restoration is in place or has fallen.
Measured: 24 months
Secondary outcomes (1)
marginal adaptation score alpha
It represents the marginal integrity of the restorations. It is scored as alpha (perfect marginal adaptation), bravo (detectable marginal discrepency, clinically acceptable) or charlie (marginal crevice, clinically unacceptable). The examination of marginal adaptation is performed by clinical examination of the restoration with probe.
Measured: 24 months
