Clinical Performance and Immediate Child and Parental Satis-faction With BioFlx Crowns in Primary Molars: A Prospective, Single-Arm, Non-Randomized Interventional Study

Informed consent was obtained from the parents/guardians of participating children after a detailed explanation about the treatment along with possible outcomes, risks, benefits, and discomforts is provided. In addition, assent forms were obtained from the participating children who are seven years and older. Healthy children or children with mild, stable systemic medical conditions, who were cooperative and required at least one full-coverage restoration in a primary molar were recruited from the pe-diatric dentistry clinics at King Abdulaziz University Faculty of Dentistry. BioFlx crowns were placed by trained pediatric dentistry residents under a consultant's supervision. Immediately after crown cementation, proximal contact and occlusion were recorded. At three- and six-month fol-low-up visits, clinical outcomes evaluated were the proximal contacts, occlusion, crown retention, staining, wear of the opposing tooth, marginal integrity, and any changes in the crown material surface. In addition, plaque accumulation and gingival health around each crowned tooth were assessed at the tooth level. Immediate post-treatment satisfaction of children and their parents was assessed following crown cementation.
