Filling

 

in dentistry, the restoration of the shape and physiological functioning of a tooth by means of an inlay. The filling of teeth prevents progress of dental caries and isolates affected tissues from the microorganisms present in the mouth.

Cavities formed in the hard tissues of the teeth are filled with a malleable material that eventually hardens. A tooth is prepared to receive a filling by the surgical excision of tooth tissues that have lost their firmness. A cavity of a definite outline is then formed. Temporary fillings are sometimes used to cover cavities in which medicinal substances have been applied.

Permanent fillings are made from materials with sufficiently high sturdiness, hardness, and resistance to the effects of saliva. They differ little in color from the crown of the tooth and are harmless to both the tooth and the entire body. Filling materials include phosphate cements, silicate cements, silicophosphate cements, acrylic plastics, preparations based on epoxy resins, and amalgams consisting of a hard solution of metals (silver) in mercury. When filling teeth with amalgams, plastics, or silicate cements, a packing of phosphate cement or artificial dentin (zinc-sulfate cement) is made, and then the filling material is injected into the tooth canal with a special probe needle or plugger.

45] There is no need to apply retrograde filling in root canal, if treatment fails or root end resection has to be performed when MTA is filled 5 mm apically, as it is difficulty to handle, obturation of curved root canals is difficult, longer setting time because of it should not be applied in 1 visit.
Sealing ability of amalgam, super EBA cement and MTA when used as retrograde filling materials.
To make this possible, especially in cases where it is difficult to extract the cast pin and the crown, it is necessary to resort to surgical techniques and to use retrograde filling materials with ideal characteristics to stimulate the healing of affected tissues.
The purpose of this study was to compare the success rate of two root end filling materials both clinically and radiographically using MTA and zinc free amalgam as retrograde filling in surgical endodontic.
One group was treated with MTA and the other group was treated with zinc free amalgam as a retrograde filling.
The cavity for retrograde filling was prepared with small carbide round bur.
The other group received amalgam as retrograde filling.
Since long different retrograde filling materials are in use to provide apical seal including amalgam, gutta-percha, ZnO cement, gold foil pellets, bio-bond glas-sionomer, Ketac-silver, EBA cement and MTA.
6% in pa-tients where amalgam retrograde filling was used after apicoectomy (Table 1).
3% in patients where amalgam retrograde filling was used after apico-ectomy (Table 2).
The retrograde filling materials should pro-vide a hermetic seal, should be non-toxic, non-carcino-genic, biocompatible and dimensionally stable.
