Clinical trial Recruiting at 2 sites Interventional Ages 4 to 9

Fast versus standard light-curing for composite fillings in baby molars

Official title: A Multi-center, Randomized-controlled, 12-month, Split-mouth, Non-inferiority Clinical Trial to Compare the Safety and Performance of Two Different Curing Modes in the Direct Filling Therapy With a Flowable Bulk Fill Composite in Class I and II Deciduous Teeth

Run by Ivoclar Vivadent AG · NCT07212660 · Data updated 2026-11-12

This test tries whether a very quick 5-second high-intensity light cure or the usual 10-second cure is safe and works well for composite fillings in primary molars in young children.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are children whose legal guardians consent and who have two deciduous molars in different quadrants needing class I or II direct fillings and who can cooperate during treatment.

Probably not a fit

Children with active severe tooth pain, badly resorbed roots, need for direct pulp therapy or pulpotomy, allergies to study materials or anaesthetics, or who cannot be adequately isolated or are noncompliant are unlikely to benefit from this comparison.

What this trial studies

This interventional comparison enrolls children who need direct posterior composite restorations in primary molars and treats teeth with either a fast curing mode (5 seconds at 2000 mW/cm²) or a conventional curing mode (10 seconds at 1200 mW/cm²) using a flowable composite. Treatments are performed in routine dental clinic settings and clinical performance and safety of the restorations are followed over time. The trial targets common practical issues in pediatric dentistry, such as limited cooperation and moisture control, by shortening light-curing time in the experimental arm. Outcomes will include restoration survival, clinical performance measures and any adverse events related to the materials or procedures.

Why it matters

Potential benefit: If successful, children could receive safe composite fillings with much shorter chair time, reducing stress and improving comfort during dental visits.

How similar studies have gone: High-intensity, short-duration light-curing has been explored in other dental settings and some reports suggest comparable immediate outcomes, but long-term data specifically in primary molars are limited.

Inclusion Criteria:

* Consent of a legal representative (usually parents)
* 2 deciduous molars in the need of direct filling therapy class I and/or II in different quadrants (primary or secondary caries, filling loss)

* Sufficient language skills of legal representative and children
* Teeth in the need of indirect pulp capping if necessary (Operator decision)

Exclusion Criteria:

* Cognitive impairment not age-appropriate
* Sensitive tooth (pain at night, irritation-persistent pain, buccal swelling, percussion sensitivity)
* Teeth with severely resorbed roots (anormal tooth mobility)
* Direct pulp capping
