简要总结
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.

结局指标
主要结局
Plaque accumulation
时间窗: 6 months and 12 months
Measured using the Löe and Silness index, where each of the four surfaces of the crown (buccal, lingual, mesial, and distal) was scored from 0 to 3 (0 = no plaque, 3 = abundance of soft matter). The scores from the four areas were added and divided by four to obtain the plaque index
次要结局
- crown retention(6 months and 12 months)
