ObjectiveTo identify outcomes reported in peer-reviewed literature for evaluating the care of adults with acute dental pain or infection.DesignSystematic narrative review.Setting/participantsPrimary research studies published in peer-reviewed literature and reporting care for adults with acute dental pain or infection across healthcare settings. Reports not in English language were excluded.Study selectionSeven databases (CINAHL Plus, Dentistry and Oral Sciences Source, EMBASE, MEDLINE, PsycINFO, Scopus, Web of Science) were searched from inception to December 2020. Risk of bias assessment used the Critical Appraisal Skills Programme checklist for randomised controlled trials and Quality Assessment Tool for Studies of Diverse Design for other study types.OutcomesNarrative synthesis included all outcomes of care for adults with acute dental pain or infection. Excluded were outcomes about pain management to facilitate treatment, prophylaxis of postsurgical pain/infection or traumatic injuries.ResultsSearches identified 19 438 records, and 27 studies (dating from 1993 to 2020) were selected for inclusion. Across dental, pharmacy, hospital emergency and rural clinic settings, the studies were undertaken in high-income (n=20) and low/middle-income (n=7) countries. Two clinical outcome categories were identified: signs and symptoms of pain/infection and complications following treatment (including adverse drug reactions and reattendance for the same problem). Patient-reported outcomes included satisfaction with the care. Data collection methods included patient diaries, interviews and in-person reviews.DiscussionA heterogeneous range of study types and qualities were included: one study, published in 1947, was excluded only due to lacking outcome details. Studies from dentistry reported just clinical outcomes; across wider healthcare more outcomes were included.ConclusionsA combination of clinical and patient-reported outcomes are recommended to evaluate care for adults with acute dental pain or infection. Further research is recommended to develop core outcomes aligned with the international consensus on oral health outcomes.PROSPERO registration numberCRD42020210183.
