“…Cold atmospheric plasmas (CAPs) have attracted much attention from researchers due to their unique features, such as low gas temperatures, abundant chemically reactive species and flexible operations with the removal of vacuum system, and have bright application prospects in the fields of bio-medicine, advanced materials synthesis and modifications, energy saving and environmental protection, etc. Among the preceding CAP applications, biological and medical applications of the CAPs have become one of the research focuses in the interdisciplinary fields of plasma physics and chemistry, biochemical engineering, medical science and clinical operations [1][2][3]. As one of the most three promising application fields in plasma medicine at the present time, i.e., cancer therapy, dermatology and stomatology, study of the CAPs in dentistry can also be regarded as a miniature of the plasma medicine, including indirect applications of CAPs for the surface modifications of biomedical materials, and direct applications of CAPs for the medical therapy [2,3].…”
