New white crowns for Kids' cavities could replace metal smiles
NCT ID NCT06713330
First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study compares a new flexible white dental crown (BioFLX) to the standard stainless steel crown for treating cavities in baby molars. Researchers want to see if the white crown works just as well as the metal one in terms of gum health, plaque buildup, wear, and staying in place. The trial involves 50 children aged 2 to 5 who need crowns under general anesthesia.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BioFLX crown (flexible white resin crown)
- What this could lead to
- If successful, this could offer a more natural-looking, metal-free option for dental crowns in children, potentially improving aesthetics and comfort.
- What could go wrong
- This is a small pilot study with only 50 children, so results may not apply to all kids. The new crown might wear faster or not stay in place as well as the metal version.

Inclusion Criteria: * CCHMC pediatric dental patients between the ages of 2 years to 5 years and 11 months, at the time of recruitment, who present to any CCHMC dental clinic location and then are found to need full mouth dental rehabilitation. * Patients who speak the most common languages at CCHMC will be able to be recruited for the study. o English, Spanish, Arabic, Uzbek, Nepali, Chinese Mandarin, Russian, French. * These patients must qualify for treatment at the CCHMC dental in-office general anesthesia (IOGA) area or the Procedure Center (PC). IOGA and the PC will be selected as a venue of treatment to control behavioral factors. This is not specific to the study and would occur due to their treatment needs. * Participants will have at least one pair of contralateral primary molars with the need for a full coverage restoration in the same arch. * For example, tooth A \& J, B \& I, S \& L, or T \& K * For each participant, a minimum of one SSC or one PRC will be randomly assigned via a split mouth design to be placed as part of the study. * Need for Full coverage and high caries risk will be defined by AAPD Best Practice Guidelines 2,16 o Teeth With 1. Extensive caries 2. Cervical decalcification 3. Developmental defects (e.g., hypoplasia, hypocalcification) 4. When failure of other available restorative materials is likely (e.g., interproximal caries extending beyond line angles, patients with bruxism) 5. Following pulpotomy or pulpectomy 6. For definitive restorative treatment for high caries-risk children as defined by the AAPD 7. For patients who exhibit high caries risk and whose treatment is performed under sedation or general anesthesia. This would be normal and not specific to the study. * Participants who consent to the study, and who can be available for follow-up recall appointments. * All participants will be ASA I or ASA II as defined by the American Society of Anesthesiologists.15 Exclusion Criteria: * Participants who do not meet inclusion criteria will be excluded. * Participants whose teeth do not meet the inclusion criteria. * Participants who do not wish to participate in the study. * Patients who do not wish to or cannot reliably return for follow-up visits. * Red dye allergy as patient will not be able to be plaque disclosed during follow-up visits. * Participants who do not speak English, Spanish, Arabic, Uzbek, Nepali, Chinese Mandarin, Russian, French.
