Objective:
To investigate the causes and the treatment of endodontic interappointment emergencies.
Methods:
An analysis were made for 55 teeth with endodontic interappointment emergencies. The root canals were sealed with dexamethasone and metronidazole,and filled with Vitapex add gutta-percha point after one week. An evaluation of curative effect was made after following up one year.
Results:
The total incidence of endodontic interappointment emergencies was 12.59%(55/437). There was significant difference between pulpitis and pulp necrosis or apicitis(P<0.01). There was significant difference between anterior teeth and posterior teeth (P<0.01). The success rate was 92.7% after following up one year.
Conclusion:
The cause of endodontic interappointment emergencies was related to pulp status and tooth location,etc. The treatment that sealed the root canals with dexamethasone and metronidazole and filled with Vitapex add gutta-percha point is of availability.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
