Class I Dental Caries

Procedure: class I restoration placement
Registration Number
NCT05559333
Lead Sponsor
Hacettepe University
Brief 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. 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.

Primary Outcome Measures
NameTimeMethod
Retention Alpha for at least 90% of the restorations24 months

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.

Secondary Outcome Measures
NameTimeMethod
marginal adaptation score alpha24 months

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.
