Endodontics
Endodontics
Mineral trioxide aggregate (MTA), composed mainly of tricalcic silicate, tricalcic alluminate, bismuth oxide, is a particular endodontic cement. It is made of hydrophilic fine particles that harden in the presence of dampness or blood. It is biocompatible, radiopaque and it is harder to infiltrate, compared to classic materials for root filling such as amalgam, cements, Super-EBA, and IRM. and SEM studies of sections and copies in resin of root neoapices filled with amalgam, IRM, Super-EBA and MTA, as well as tests of microinfiltration have shown that MTA has excellent sealing capacities
Benefits
1. Benefits of irrigation during endodontic work Making a wet environment during preparation the dentin shaving floating to the chamber files and reamers are less likely to break when the canal is wet The irrigant that are typically used have the function of necrotic tissue solvent The irrigants loosen depris, pulp tissue, from irregular dentin walls Most irrigants are germicidal also have ableaching action to lightens teeth discolored by traumapost operative darkness.
2. Useful irrigantsSodium hypochlorite(naocl) most widely used the pH of sodium hypochlorite is near 12. During the treatment of a root canal,the increase in pH likely createsa microenvironment that is notparticularly hospitable to bacteria in the root canal system.
Advantages
1. The EndoVac system lowers the risks associated with irrigationclose to the apical foramen.
2. Another advantage of the reversed flow of irrigants may be good apical cleaning at the 1-mm level and a strong antibacterial effect when hypochlorite is used.
