Treating pediatric patients with early childhood caries can be challenging. For clinicians, managing a young child while ensuring high-quality treatment is difficult. It is essential to have the best equipment and materials available. Today, aesthetics are crucial in managing decayed teeth, with zirconia crowns often preferred for their visual appeal, although they require substantial preparation. The newly developed Bioflx crown, combining stainless steel and zirconia properties, offers an alternative solution.

| Bioflex Crowns | Other | A preformed crown of similar size will be selected. Tooth preparation will be done using a tapered diamond bur to reduce the occlusal surface, including the central groove, by 1-1.5 mm. The proximal surfaces will be prepared by approximately 0.5 mm to clear the contact area. |

| Change in clinical success | The crowns were evaluated clinically according to the following criteria: 1. Length: the margin is at the gingival crest or is extended to the cemento-enamel junction. 2. Position: crown is not rotated. 3. Polish: no scratches or roughness. 4. Cement: no excess cement remains in the sulcus. If all criteria fulfilled the crown is considered acceptable clinically, if not it is considered unacceptable. | baseline, 6 months, and 12 months |
| parental satisfaction | The questionnaire for assessing parental satisfaction includes four main categories for rating the aesthetic characteristics: size, shape, color, and stain. Responses will be recorded on a five-point Likert scale, ranging from 1 (not at all satisfied) to 5 (very satisfied). | through study completion, an average of 6 months |

| Stainless steel crown | Other | An appropriately sized preformed stainless-steel crown will be selected. Tooth preparation will involve using a tapered bur ) to reduce the occlusal surface by 1 to 1.5 mm, with interproximal reduction made on the mesial and distal sides. The selected crown size will be checked, and a trial fit will be conducted prior to cementation. Crimping pliers will be used, and the crown will be cemented with Type 1 glass ionomer cement. Any excess cement will be removed, and proper occlusion will be verified. |
