Abstract:
Endodontics is a branch of dentistry based on the health of the root canal system, promoting
cleaning of these, often associated with postoperative pain events. Several factors have been
suggested as propitiators of the symptom. This paper aims to gather data from the literature
that can explain the occurrence and intensity of postoperative pain symptomatology in
endodontics and which variables may be involved in this process. We used 45 scientific
articles from the databases: SciELO, MEDLINE, Lilacs, PubMed, BBO and BVS, found in
Portuguese, English and Spanish, using the descriptors: Post Operative Pain, Endodontics,
Dental Pulp; with period restriction from 2009 to 2019. Post-operative endodontic pain is
reported in approximately half of the cases, with preoperative pain being a strongly associated
factor. The number of clinical sessions did not exert differences in pain, as well as the use of
different instrumentation techniques evaluated. Vital pulps exert a higher incidence of this
symptom. Enlargement of foramen was shown to be more associated with pain, while the
execution of foraminal patency showed the capacity of not producing it. Calcium hydroxide,
chlorhexidine and antibiotic paste showed important intracanal medications, as well as
sodium hypochlorite, chlorhexidine and ethylenediaminetetraacetin acid werw satisfactory
irrigating solutions. All variables showed some relationship with postoperative pain in
endodontics, however they did not express themselves expressively, suggesting that more
studies are needed on this topic.
