DOES THE ULTRASONIC ACTIVATION OF CALCIUM SILICATE-BASED SEALERS AFFECT THEIR PHYSICOCHEMICAL PROPERTIES?

This study aimed to evaluate the influence of ultrasonic activation (UA) on the physicochemical properties of calcium silicate sealers. Nine experimental conditions were created based on the calcium silicate sealers (Bio-C Sealer, Sealer Plus BC, and Bio Root RCS) and the ultrasonic activation (no activation, 10 seconds, and 20 seconds). Then the experimental groups were BC-NA, BC-10, BC-20, SPBC-NA, SPBC-10, SPBC-20, BR-NA, BR-10, and BR-20. The sealers were handled according to the manufacturer's instructions. A 3 mL syringe was adapted to receive 1 mL of sealer. Activation was performed with an ultrasonic insert 20/.01. The mold for the physicochemical analysis was filled and evaluated according to the ANSI/ADA specification nº. 57: initial and final setting time, flow, radiopacity and solubility. Tests were also performed to evaluate pH and calcium ion release with experimental periods of 1, 24, 72, and 168 hours with a pH meter and colorimetric spectrophotometer. Data were analyzed by one-way analysis of variance and post-hoc Tukey tests. The significance level was set at 5%. The time of UA progressively delayed the initial setting time for all calcium silicate sealers (P < .05). Twenty seconds of UA increased the mean flow values of Sealer Plus BC and Bio-C Sealer compared to NA (P < .05). UA did not influence the radiopacity and solubility of the tested sealers (P > .05). UA for 20 seconds enhanced the pH levels and the calcium ion release of Sealer Plus BC and Bio-C Sealer at 168h (P < .05). UA for twenty seconds interferes with some physicochemical properties of calcium silicate sealers

PHARMACOLOGICAL MANAGEMENT OF ANXIETY ON PAIN OCCURRENCE DURING ROOT CANAL TREATMENT: A SYSTEMATIC REVIEW

This study aims to answer the question: “Does the pharmacological management of dental anxiety influence on pain occurrence during root canal treatment?” Searches on MEDLINE/PubMed, Cochrane Library, Web of Science, Scopus, EMBASE and Open Grey were conducted until February 2021. Only randomized clinical trials were included. Cochrane risk of bias tool for randomized trials (RoB 2) was used. Overall quality of evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. Initial screening resulted in 510 studies. 43 were excluded for being duplicates. Of 467 eligible papers, ten studies met the inclusion criteria and were selected for full-text reading and four studies were included for final analysis. GRADE analysis demonstrated a low quality of evidence. There is no sufficient evidence to determine whether the pharmacological control of anxiety can influence in the intraoperative pain occurrence
