3D-Printed Resin Crowns Versus Bioflx Crowns in Primary Molars
Sponsor: Faculty of Dental Medicine for Girls
Summary
This randomized comparative clinical trial will evaluate and compare the clinical performance of preformed three-dimensional (3D)-printed resin crowns and Bioflx crowns in children with pulp-treated primary molars requiring full coronal restoration. The study will use a split-mouth design in which eligible children have two comparable contralateral primary molars treated with the two crown types, with the crown allocation to the right or left tooth determined by a computer-generated random sequence. Crown survival will be the primary outcome. Secondary outcomes will include the modified plaque index, modified gingival index, and occlusal wear. Clinical assessments are planned at one week and at 3, 6, and 12 months after treatment.

Interventions
Preformed 3D-Printed Resin Crown
Preformed three-dimensional (3D)-printed resin crowns will be used for full coronal restoration of pulp-treated primary molars in children aged 3-9 years. The clinical performance of these crowns will be evaluated in a randomized split-mouth design, with each participant receiving a 3D-printed resin crown on one primary molar and a Bioflx crown on the contralateral molar. Outcomes will be assessed at 1 week and 3, 6, and 12 months after treatment.
Bioflx Crown
Bioflx crowns will be used as the comparison intervention for full coronal restoration of pulp-treated primary molars in children aged 3-9 years. In this randomized split-mouth study, each participant will receive a Bioflx crown on one primary molar and a preformed 3D-printed resin crown on the contralateral molar. Outcomes will be assessed at 1 week and 3, 6, and 12 months after treatment.
