Study summary

The clinical performance of a bioactive composite (alkasite-based), a nanohybrid resin composite and a bulk-fill resin composite in class II restorations will be evaluated and compared. After recruiting participants with at least 3 approximal caries lesions, all restorations will be placed by a single clinician. All caries lesions will be removed before restoring. Cavities will be divided into three groups: a bioactive composite [Cention Forte Ivoclar Vivadent, Schaan, Liechtenstein], a nanohybrid resin composite [Tetric N-Ceram2 (Ivoclar Vivadent, Schaan, Liechtenstein)] and a bulk-fill resin composite [Tetric N-PowerFill2 (Ivoclar Vivadent, Schaan, Liechtenstein)], All restorative procedures will be conducted according to manufacturers' instructions. Restorations will be scored using FDI criteria after a week (baseline) 6, 12, 24, 36 and 48 months. Descriptive statistics will be performed using chi-square tests.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Apr 2026; primary completion for Jun 2026, 2 months later.

Of 32 non-industry interventional studies with no phase under Tooth Diseases, half reached primary completion within 8 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 18. This study's planned 2 months is below that.

Counting every sponsor, half of 39 studies reached it within 12 months; a quarter within 4 and three quarters within 42.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 1, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
