Dental fillings are often used to fill cavities or holes after root canal treatment. [6] They can also be used to restore worn teeth or fill gaps between teeth. [ 7 ] Fillings can be made of amalgam (a metal alloy) or materials such as composite resin and glass ionomer.
The cost of the restoration is typically cheaper than composite restorations. Disadvantages of amalgam include poor aesthetic qualities due to its colour. Amalgam does not bond to tooth easily, hence it relies on mechanical forms of retention. Examples of this are undercuts, slots/grooves or root canal posts.
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 treatment to give cuspal coverage. It can also be used if there is minimal contour of remaining coronal tooth tissue with little retention. [7]
The root canal filling material (3, 4, and 10) does not extend to the end of the tooth roots (5, 6 and 11). The dark circles at the bottom of the tooth roots (7 and 8) indicated infection in the surrounding bone. Recommended treatment is either to redo the root canal therapy or extract the tooth and place dental implants.
Dentists trained worldwide at different institutions in different times may have varied ways of treatment planning and case selection, resulting in varying treatment recommendations. Traditionally, crown and bridge work requires more than one visit, and the extra time necessary for the procedure can be a drawback; nevertheless, the improved ...
After endodontic therapy has been executed, or re-executed, successfully, and the canals can no longer provide a nutrient-rich habitat for microbes, [31] the issue of bone healing comes into focus. Ostensibly, then, for regeneration to occur, the root canal system must have been decontaminated and further access to microbial invasion must be ...
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]
However, there are also disadvantages, during the preparation for the post space there is a risk of perforation, a post can also make a tooth more likely to fracture, it makes future orthograde root canal treatment much more difficult and finally it is very destructive and requires excessive removal of tooth tissue.
