Article Synopsis
- The study aimed to create a protocol for acid-etching two types of dental cements, Biodentine and Cimmo DTA, by examining their compressive strength, bond strength, and surface characteristics after various etching times.
- Four groups of test specimens (n=12) for each cement were tested at different acid-etching intervals of 0, 5, 10, and 15 seconds.
- Results showed Biodentine had significantly greater compressive strength than Cimmo DTA, and the optimal etching methods differed: selective etching for Biodentine and a full 15-second etch for Cimmo DTA.
Introduction: Determination of the glide path is recommended before using rotary instruments. This study aimed to evaluate the dynamic cyclic fatigue resistance of new and used glider rotary instruments in up to 6 root canals.
Methods: Seventy-two TruNatomy Glider files were used for the preparation of root canals of extracted lower molars, which were then submitted to the dynamic cyclic fatigue test carried out in a curved metallic artificial canal.
Objective: To develop a chitosan-xanthan (CX) membrane associated with Hydroxyapatite (HA) and different concentrations of graphene oxide (GO).
Methodology: The CX complex was associated with the hydroxyapatite-graphene oxide (HAGO) nanocomposite in different concentrations. The experimental groups were:1) CX; 2) Chitosan-Xanthan/Hydroxyapatite (CXHA); 3) Chitosan-Xanthan/Hydroxyapatite-Graphene Oxide 0.
