A temporary crown (white) on a tooth after endodontic therapy. A temporary crown (provisional crown, interim crown) is a temporary (short-term) crown used in dentistry.Like other interim restorations, it serves until a final (definitive) restoration can be inserted.
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]
Pericoronitis is inflammation of the soft tissues surrounding the crown of a partially erupted tooth, [1] including the gingiva (gums) and the dental follicle. [2] The soft tissue covering a partially erupted tooth is known as an operculum, an area which can be difficult to access with normal oral hygiene methods.
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.
The treatment plan may vary with the addition of a root canal treatment or a temporary crown for the reconstruction of a new crown. Fracture of a porcelain veneer or a porcelain-fused-to-metal crown; Immediate management includes a chair side repair of the fractured veneer with composite material.

This photo shows the application of luting cement onto a temporary dental crown. The use of lute in this case is therefore considered provisional because of the short duration of use of the crown (up to six weeks). The crown will eventually be replaced by a permanent crown.
Pulpitis is reversible when the pain is mild to moderate and lasts for a short time after a stimulus (for instance cold); or irreversible when the pain is severe, spontaneous, and lasts a long time after a stimulus. Left untreated, pulpitis may become irreversible, then progress to pulp necrosis (death of the pulp) and apical periodontitis ...
