This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tested two types of tooth-colored fillings for cavities in back teeth: direct composite (placed directly in the tooth) and indirect composite (made in a lab and then cemented in). 90 adults with cavities received one of the two fillings. Researchers checked how well the fillings held up using standard dental criteria. The goal was to see which option works better for larger cavities.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
composite resin (direct and indirect)
What this could lead to
If successful, this could help dentists choose the best filling material for large cavities, balancing durability and cost.
What could go wrong
This is a small, completed study with only 90 participants. Results may not apply to everyone, and long-term outcomes beyond the study period are unknown.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The characteristics of the teeth were recorded prior to any restorative procedures. Periapical radiographs were used to assess the status and extent of caries, as well as to identify any potential periodontal or periapical pathologies that might necessitate endodontic treatment. The treated teeth were vital, asymptomatic, and in occlusal contact. Indirect composite restorations were applied to teeth that had caries, old composite or amalgam restorations, secondary caries, or teeth with cuspid loss where the isthmus width exceeded two-thirds of the intercuspal distance.

Ages
