Child and Parental Satisfaction of Bioflx Crowns Compared to Zirconia Crowns In Primary Molars

Evaluation Of Child and Parental Satisfaction Of Bioflx Crowns Compared To Zirconia Crowns On Primary Molars

The goal of this clinical trial is to evaluate the child and parents satisfaction of Bioflx crowns compared to zirconia crowns in the restoration of primary molars. The main question[s] it aims to answer : Is there a difference in the child and parents satisfaction levels between BioFlx crowns and zirconia crowns in the restoration of primary molars?" The study will also assess the clinical performance of both types of crowns in terms of Retention, occlusal wear, gingival health, as well as preparation time.

The management of severely decayed primary teeth in pediatric dentistry often requires the use of crowns to restore function and aesthetics. Traditional stainless-steel crowns (SSCs) have been widely used due to their durability and cost-effectiveness; however, their metallic appearance and lack of aesthetic appeal have prompted the development of alternative materials such as zirconia and Bioflx crown. Zirconia crowns are recognized for their superior aesthetics and biocompatibility, making them a preferred choice for parents who prioritize appearance. However, they can present challenges in terms of retention, preparation requirements, and cost. Bioflx crowns, a newer material in pediatric dentistry, aim to combine aesthetic appeal with flexibility and improved adaptability to tooth anatomy. Despite their growing popularity, limited research directly compares the child and parental satisfaction between zirconia and Bioflx crowns. It remains unclear which material offers the best balance of functional, aesthetic, and patient-centered outcomes.This gap in knowledge hinders evidence-based decision-making when selecting crowns for pediatric patients. Zirconia crowns have gained prominence in pediatric dentistry as an alternative to stainless steel crowns for primary molars. While SSCs have long been valued for their durability and ease of placement, their metallic appearance often presents an aesthetic concern for parents and patients. Zirconia crowns provide a more natural, tooth-colored alternative, making them a preferred option in cases where aesthetics is a priority. One of the main advantages of zirconia crowns is their biocompatibility, as they demonstrate lower plaque accumulation and gingival inflammation. Additionally, zirconia crowns offer superior mechanical properties, including high flexural strength and excellent fracture resistance, making them a long-lasting restorative option. Their wear resistance further supports their use in pediatric patients, particularly those with heavy occlusal forces. This study stems from the need to bridge the gap in current research regarding the satisfaction and the effectiveness associated with Bioflx crowns. Understanding whether Bioflx crowns offer superior aesthetic and functional outcomes compared to Zirconia crowns could influence clinical decision-making in pediatric dentistry. This is especially relevant as parents increasingly seek restorations that provide both durability and a natural appearance for their children.
