Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this clinical trial was to compare clinically three different crowns for primary molars; stainless steel crown, zirconia crown and Bioflx crown.

the main questions it aims to answer are: is Bioflex crown is an alternative to stainless steel crown and zirconia crown? Seventy-five patients their age range between 3 and 8 years participated in this study. The participants are divided into three groups representing group A for stainless steel crown (n=25), group B for zirconia crown (n=25) and group C for Bioflx crown (n=25). Plaque index, crown retentivity and gingival index will be evaluated at evaluated at baseline, 6 and 12 months.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

This research was designed as a randomized controlled trial conducted by a single operator to minimize operator-induced errors. A total sample of 75 primary molars was determined, allowing for potential dropouts, and was evenly distributed into three groups of 25. Each group recieved different crown, groups A for stianless steel crown, group B for zirconia crown and group C for Bioflx crown. At 6 and 12 months follow up, each crown was evaluated clinically such as plaque index , crown retentivity and gingival index.

stainless steel crown

Participants in this arm will receive stainless steel crowns for primary teeth.

Group Type ACTIVE_COMPARATOR

stainless steel crown

Intervention Type DEVICE

Participants in this arm received a stainless steel crown for primary teeth restoration. The crowns were selected based on the clinical assessment of the patient's dental need.

Zirconia crown

Intervention Type DEVICE

Participants in this arm received a zirconia crown for primary teeth restoration. The crowns were selected to provide a more aesthetic and durable option compared to stainless steel.

Bioflx crown

Intervention Type DEVICE

Participants in this arm received a Bioflx crown, which is a flexible, biocompatible material often used for pediatric crowns.

zirconia crown

Participants in this arm will receive zirconia crowns for primary teeth.
