Objective: To evaluate the level of dental anxiety (DA) and dental pain (DD) at different times in root canal treatment during the COVID-19 pandemic. Materials and methods: Observational, descriptive, and longitudinal study. The sample consisted of 68 participants from the Stomatology Clinic of the Hospital Militar Central (HMC), who met the inclusion and exclusion criteria. The procedure consisted of recording the level of AD and DD of the patients at different times during root canal treatment using a visual analog scale (VAS). Results: Before the procedure, participants showed 3.66±1.83 of AD and 4.54±1.79 of DD; during the procedure, they obtained values of 3.13±1.96 and 2.09±1.39 of AD and 2.96±1.57 and 1.82±1.09 of DD; and at the end of the procedure, they had 0.75±0.74 of AD and 0.53±0.72 of DD. Conclusions: AD and DD were found to be present before starting treatment, but...

Traditionally, calcium hydroxide (HC) was considered the material of choice for direct pulp capping (RPD); but this has changed over the years due to the various disadvantages it presents. Calcium silicate-based cements (CSC) have properties that are advantageous to HC such as: bioactivity, biocompatibility, shorter setting time, sealing capacity and resistance, which they are used in a variety of endodontic procedures, including RPD.This review article compiles information from the manual search of original scientific research articles and literature reviews of the Medline / PubMed database. The varieties of CSC, their mechanism of action, disadvantages, related factors and rates of clinical success in their application in cases of RPD are described.
