“…The use of desensitizers can safeguard dental pulp and distinctly release related symptoms (Clark & Levin, 2016; Felix & Ouanounou, 2019), which is economical, effective, and practical. As one kind of desensitizers, bioactive glass (BAG) has been introduced in the treatment of DH in recent years, especially 45S5 (Bakry et al, 2011; Bevilacqua, Catelan, AraÚJo, Saraceni, & Sampaio, 2016; Chen et al, 2013). Embodying oxides of Ca, P, Na, and Si, BAG can induce calcium and phosphorus ions to generate hydroxyapatite, which can seal or reduce the diameter of dentinal tubules, thus isolating external stimulation and acquiring anesis of DH (Tirapelli, Panzeri, Soares, Peitl, & Zanotto, 2010).…”
