An observational study in Dental Diseases, sponsored by University Hospital, Toulouse. Recruiting at 9 sites in France. Open to participants aged 12 Years to 18 Years. Per ClinicalTrials.gov, last updated 2026-05-12.
Sponsored by University Hospital, Toulouse · Observational
The main objective of this study is to assess the prevalence of dental discoloration (dental dyschromia) in children who experienced high levels of bilirubin in their blood (hyperbilirubinemia) during their early years. The study will also examine risk factors associated with this condition, such as the duration and severity of hyperbilirubinemia, underlying diseases, and treatments received.
The researchers hypothesize that the quality of life of individuals with dental dyschromia is lower than that of individuals without dyschromia. The results of this study will be used to discuss coverage for dental care with health insurance for children affected by this condition.
