The PhD thesis consists of five laboratory studies which focused on the investigation of the effect of a new strontium-doped bioactive glass on dental hard tissues. The dataset contains various measurements for assessing the antibacterial effect, remineralizing effect and preventive effect of this study bioactive glass. SEM, TEM images show the typical morphology of newly formed apatite, XRD and other means display the typical pattern of the apatite. Other data acted as a supplementary to my study.
