BACKGROUND
Composites are the widely used restorative materials, and over the year, newer restorative composites have been introduced to eliminate the drawbacks of previous ones. The recent advance in restorative dentistry is bioactive restorative materials. However, bacterial plaque formation on these restorations is the primary reason for secondary caries.
AIMS AND OBJECTIVES
The purpose of this study was to do the comparative evaluation of bioactive restorative composites (Beautifil Flow Plus, Activa BioACTIVE, and Filtek Z250 XT as control) for their antibacterial efficacy under in vitro conditions.
MATERIALS AND METHOD
Thirty material blocks were used for this evaluation. Antibacterial efficacy was checked against Streptococcus mutans and observed under confocal laser scanning microscopy.
RESULTS
The results showed that Activa BioACTIVE shows maximum number of dead bacteria on the material surface compared to other groups.
CONCLUSION
It can be concluded as it has maximum antibacterial efficacy among tested materials.
背景
复合材料是广泛使用的修复材料，近年来，出现了更新的修复复合材料以消除之前材料的缺点。最近在修复牙科领域的进展是生物活性修复材料。然而，这些修复体上细菌菌斑的形成是继发龋的主要原因。
目的
本研究的目的是在体外条件下对生物活性修复复合材料（Beautifil Flow Plus、Activa BioACTIVE 和 Filtek Z250 XT 作为对照）进行抗菌效果的比较评价。
材料和方法
本评估使用了 30 个材料块。使用激光共聚焦扫描显微镜检查对变异链球菌的抗菌效果。
结果
结果表明，与其他组相比，Activa BioACTIVE 材料表面的死菌数量最多。
结论
可以得出结论，它在测试材料中具有最大的抗菌效果。
