Mineral trioxide aggregate (MTA) is a recent development of the 1990s [21] initially as a root canal sealer but has seen increased interest in its use as a direct pulp-capping material. [10] The material comprises a blend of tricalcium silicate , dicalcium silicate and tricalcium aluminate ; bismuth oxide is added to give the cement radiopaque ...
Composites and amalgam are used mainly for direct restoration. Composites can be made of color matching the tooth, and the surface can be polished after the filling procedure has been completed. Amalgam fillings expand with age, possibly cracking the tooth and requiring repair and filling replacement, but chance of leakage of filling is less.
In internal resorption, root canal therapy is performed, a putty mixture of MTA is inserted in the canal using pluggers to the level of the defect. Gutta percha and root canal sealer are placed above the defect to complete the root canal treatment. In direct cases, the canal may be completely obturated with MTA.
There are several treatments where dental dam can be applied; dental restorations, endodontic treatments including root canal therapy, fissure sealants, preparation of dental crown, dental implant and some veneer placements. There is an ongoing controversy with the use and efficacy of rubber dam among dental practitioners. [7]
They are usually reserved for larger cavities as tooth conservation is paramount in current practice and small cavities can be restored with direct composites instead. Onlays are indicated when there is a need to protect weakened tooth structure without additional removal of tooth tissue unlike a crown, e.g. restoring teeth after root canal ...
In fact, water flossers "do not remove plaque as successfully as traditional floss and should be used in conjunction with floss," says Khan. "Flossing breaks down the bacteria colonies from teeth ...
Canal Enlargement (CE) Although considerable bacterial reduction can be achieved by the mechanical action of instruments and irrigation solutions, microorganisms are rarely eliminated from the root canals regardless of the instrumentation technique and file sizes employed. Due to the anatomical localization of the endodontic infection, it only ...
Whiteheads form when oil or dead skin blocks a hair follicles or pores and creates closed bumps on the skin that can appear white or yellow. Here's how to get rid of them.
