Parent Satisfaction With Zirconia, Bioflx, and 3D-Printed Crowns for Primary Molars

This study will compare parent satisfaction with three different types of dental crowns used to restore primary (baby) molars in children: zirconia crowns, Bioflx crowns, and 3D-printed crowns. Children between 3 and 7 years of age who need a full-coverage restoration of a primary molar will be invited to participate. Participants will be randomly assigned to receive one of the three crown types. All crowns will be placed by the same dentist using standardized treatment procedures. After treatment, parents will be asked to complete a questionnaire about their satisfaction with the crown. The questionnaire will evaluate several aspects, including the crown's appearance, size, shape, color, durability, and overall satisfaction. Parent satisfaction will be assessed immediately after crown placement and again one month later. The purpose of this study is to determine whether there are differences in parent satisfaction among these three crown options. The results may help dentists and families make informed decisions when choosing esthetic full-coverage restorations for primary teeth.
