Article Synopsis
- - The study assessed the effectiveness of Myracrodruon urundeuva extract with calcium hydroxide (CH) paste, focusing on cell viability, antimicrobial properties, calcium ion release, and pH changes over time.
- - Results showed that the aroeira-CH paste exhibited antibacterial activity against Enterococcus faecalis, while maintaining stable pH levels and calcium ion release, as well as not negatively impacting cell viability.
- - The findings suggest that the aroeira extract can be a useful vehicle for calcium hydroxide paste in dental applications due to its antimicrobial properties and compatibility with biological systems.
Electrochemical dissolution is a method in which fluoridated solution in direct contact with the fractured instrument receives an electrical current that speeds up fragment dissolution. The aim of this study was to assess the integrity of dentinal walls during the electrochemical dissolution of fractured rotary endodontic instruments in extracted human teeth. Forty-five human mandibular incisors subjected to the electrochemical dissolution process using fluoride solution with low NaCl concentration (LC group: NaF 12 g/L + NaCl 1 g/L, pH = 5.
