Comparative assessment of clinical performance and Streptococcus mutans adherence in primary molars restored with Bioflx and Zirconia crowns: A split-mouth pilot study

Within the limitations of this 6-month evaluation, ZCs demonstrated superior esthetics, while both Bioflx and ZCs showed comparable retention and similar reductions in S. mutans counts; however, long-term, multicenter studies are necessary to confirm the durability, longevity, and overall clinical performance of both crown types.
