If a temporary crown becomes de-cemented, it is important that a dentist examine the patient as overeruption of the opposing teeth may prevent accurate fitting of the final crown. [8] If a dentist cannot be seen in a timely manner, the temporary crown may be re-cemented by applying temporary cement to the temporary crown.
Temporary filling-materials allow the creation of hermetic coronal-seals preventing from coronal microleakage (i.e. contamination of the root canal by bacteria); their presence over the entire time-period to fill the root canal and restore the tooth crown is mandatory, for increasing the probability of the endodontic-treatment success.
Temporary crowns can either be direct, if constructed by the dentist in the clinic, or indirect if they are made off-site, usually in a dental laboratory. Generally direct temporary crowns tend to be for short-term use. Where medium-term or long-term temporisation is required, the use of indirect temporary crowns should be considered. [10]
Asking the right question, according to the good doctor, can mean paying $200 or $300 for a root canal instead of $1,200. Here’s how to ensure you don’t get drilled by extra fees at the ...
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.
The clinical examination will detect the reasons behind the failure of the restoration. Upon treatment the dentist will provide options on the tooth's prognosis, these may include a new restoration, extraction, root canal or placement of a crown. The tooth prognosis includes the tooth's vitality and restorability. [7] Crack, fracture and mobility
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 ...
A temporary dressing is a dental filling which is not intended to last in the long term. They are interim materials which may have therapeutic properties. A common use of temporary dressing occurs if root canal therapy is carried out over more than one appointment.
