Nowadays, the preservation of dental pulp vitality is an integral part of our daily therapies. The success of these treatments depends on the clinical situation as well as the biomaterials used. Mineral Trioxide aggregate and Biodentine are commonly used as pulp capping materials. One objective of vital pulp therapy is the repair/regeneration of the pulp. In addition to the initial inflammatory status of the pulp, the nature and quality of the new mineralized tissue obtained after pulp capping directly influence the success of the treatment. In order to characterize the reparative dentin, in the current study, the chemical composition and microstructure of the dentin bridge after direct pulp capping using Biodentine™ and mineral trioxide aggregate (MTA) was studied by using Raman microspectroscopy and scanning electron microscopy, respectively. The results showed that the reparative dentin bridge observed in both groups presented dentin tubules and chemical composition similar to primary dentin. With the limitations of this study, the calcium-silicate-based cements used as pulp capping materials provide an optimal environment for pulp healing, resulting in a reparative dentin resembling on certain points of the primary dentin and the regeneration of the pulp.

Background Indirect pulp capping (IDPC) is a preferred treatment for pulp preservation in primary teeth. However, the survival rate of IDPC in primary teeth and impact factors is still equivocal.Aims To evaluate the survival rate of IDPC in primary teeth with a deep carious lesion approximating the pulp but without irreversible pulpitis or periapical disease.

Aim: Clinical and radiographic evaluation of SDF versus MTA as indirect pulp capping agents in deeply carious first permanent molars.
Methodology: This study was conducted on (30) first permanent molars indicated for indirect pulp capping (IPC) randomly allocated to either SDF or MTA groups (n = 15). The molars were finally restored with glass hybrid glass ionomer restoration.

Aim: The present case-control study was planned to assess the comparative efficacy of resin-modified calcium silicate, resin-modified glass ionomer, and Dycal as pulp capping agents in indirect pulp therapy for deeply carious young permanent molars.
Materials And Methods: Thirty deeply carious young posterior teeth were treated by indirect pulp therapy. During the treatment, the cavity floor was lined with TheraCal or resin-modified glass ionomer cement (RMGIC) in the study group and with Dycal (control group) followed by GC IX and composite restoration.

Long-standing challenges including notorious side reactions at the Zn anode, low Zn anode utilization, and rapid cathode degradation at low current densities hinder the advancement of aqueous zinc-ion batteries (AZIBs). Inspired by the critical role of capping agents in nanomaterials synthesis and bulk crystal growth, a series of capping agents are employed to demonstrate their applicability in AZIBs. Here, it is shown that the preferential adsorption of capping agents on different Zn crystal planes, coordination between capping agents and Zn ions, and interactions with metal oxide cathodes enable preferred Zn (002) deposition, water-deficient Zn ion solvation structure, and a dynamic cathode-electrolyte interface.
