Bioflx crowns vs. celluloid strip crowns for front baby teeth

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this randomized study, 40 children aged 3 to 5 with bilateral front primary teeth needing full coronal restoration receive a Bioflx crown on one tooth and a Celluloid strip crown on the opposite tooth. Outcomes are measured at 3, 6, and 9 months using USPHS criteria for marginal integrity, color match, restoration integrity, and proximal contacts, along with plaque and gingival indices. The aim is to compare clinical performance and durability between the two crown types in a pediatric population. Results will inform choices for restoring primary anterior teeth in young, cooperative children.

Inclusion Criteria:

* Healthy children aged 3-5 years with cooperative behavior (Frankl's behavior rating scale 3-4).

Exclusion Criteria:

* Non-restorable teeth
* Teeth with single-surface restorations.
* Previous full-coverage restoration or large unsuccessful restoration on the target tooth.
