Corticosteroids for managing acute pain subsequent to surgical extraction of mandibular third molars: A systematic review and meta-analysis.

BACKGROUND: Corticosteroids are used to manage pain after surgical tooth extractions. The authors assessed the effect of corticosteroids on acute postoperative pain in patients undergoing surgical tooth extractions of mandibular third molars. TYPES OF STUDIES REVIEWED: The authors conducted a systematic review and meta-analysis. The authors searched the Epistemonikos database, including MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and the US clinical trials registry (ClinicalTrials.gov) from inception until April 2023. Pairs of reviewers independently screened titles and abstracts, then full texts of trials were identified as potentially eligible. After duplicate data abstraction, the authors conducted random-effects meta-analyses. Risk of bias was assessed using Version 2 of the Cochrane Risk of Bias tool and certainty of the evidence was determined using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: Forty randomized controlled trials proved eligible. The evidence suggested that corticosteroids compared with a placebo provided a trivial reduction in pain intensity measured 6 hours (mean difference, 8.79 points lower; 95% CI, 14.8 to 2.77 points lower; low certainty) and 24 hours after surgical tooth extraction (mean difference, 8.89 points lower; 95% CI, 10.71 to 7.06 points lower; very low certainty). The authors found no important difference between corticosteroids and a placebo with regard to incidence of postoperative infection (risk difference, 0%; 95% CI, -1% to 1%; low certainty) and alveolar osteitis (risk difference, 0%; 95% CI, -3% to 4%; very low certainty). PRACTICAL IMPLICATIONS: Low and very low certainty evidence suggests that there is a trivial difference regarding postoperative pain intensity and adverse effects of corticosteroids administered orally, submucosally, or intramuscularly compared with a placebo in patients undergoing third-molar extractions.

Analgesics for the management of acute dental pain in the pediatric population: A systematic review and meta-analysis.

BACKGROUND: The authors assessed the clinical effectiveness of analgesics to manage acute pain after dental extractions and pain associated with irreversible pulpitis in children. TYPES OF STUDIES REVIEWED: The authors searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and US Clinical Trials registry from inception through November 2020. They included randomized controlled trials comparing any pharmacologic interventions with each other and a placebo in pediatric participants undergoing dental extractions or experiencing irreversible pulpitis. After duplicate screening and data abstraction, the authors conducted random-effects meta-analyses. They assessed risk of bias using the Cochrane Risk of Bias 2.0 tool and certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: The authors included 6 randomized controlled trials reporting 8 comparisons. Ibuprofen may reduce pain intensity compared with acetaminophen (mean difference [MD], 0.27 points; 95% CI, -0.13 to 0.68; low certainty) and a placebo (MD, -0.19 points; 95% CI, -0.58 to 0.21; low certainty). Acetaminophen may reduce pain intensity compared with a placebo (MD, -0.13 points; 95% CI, -0.52 to 0.26; low certainty). Acetaminophen and ibuprofen combined probably reduce pain intensity compared with acetaminophen alone (MD, -0.75 points; 95% CI, -1.22 to -0.27; moderate certainty) and ibuprofen alone (MD, -0.01 points; 95% CI, -0.53 to 0.51; moderate certainty). There was very low certainty evidence regarding adverse effects. PRACTICAL IMPLICATIONS: Several pharmacologic interventions alone or in combination may provide a beneficial effect when managing acute dental pain in children. There is a paucity of evidence regarding the use of analgesics to manage irreversible pulpitis.

Injectable and topical local anesthetics for acute dental pain: 2 systematic reviews.

BACKGROUND: Local anesthesia is essential for pain control in dentistry. The authors assessed the comparative effect of local anesthetics on acute dental pain after tooth extraction and in patients with symptomatic irreversible pulpitis. TYPES OF STUDIES REVIEWED: The authors searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and the US Clinical Trials registry through November 21, 2020. The authors included randomized controlled trials (RCTs) comparing long- vs short-acting injectable anesthetics to reduce pain after tooth extraction (systematic review 1) and evaluated the effect of topical anesthetics in patients with symptomatic pulpitis (systematic review 2). Pairs of reviewers screened articles, abstracted data, and assessed risk of bias using a modified version of the Cochrane risk of bias 2.0 tool. The authors assessed the certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: Fourteen RCTs comparing long- vs short-acting local anesthetics suggest that bupivacaine may decrease the use of rescue analgesia and may not result in additional adverse effects (low certainty evidence). Bupivacaine probably reduces the amount of analgesic consumption compared with lidocaine with epinephrine (mean difference, -1.91 doses; 95% CI, -3.35 to -0.46; moderate certainty) and mepivacaine (mean difference, -1.58 doses; 95% CI, -2.21 to -0.95; moderate certainty). Five RCTs suggest that both benzocaine 10% and 20% may increase the number of people experiencing pain reduction compared with placebo when managing acute irreversible pulpitis (low certainty). PRACTICAL IMPLICATIONS: Bupivacaine may be superior to lidocaine with epinephrine and mepivacaine with regard to time to and amount of analgesic consumption. Benzocaine may be superior to placebo in reducing pain for 20 through 30 minutes after application.

Parathyroid Hormone Therapy for Managing Chronic Hypoparathyroidism: A Systematic Review and Meta-Analysis.

The efficacy and safety of parathyroid hormone (PTH) therapy for managing long-term hypoparathyroidism is being evaluated in ongoing clinical trials. We undertook a systematic review and meta-analysis of currently available randomized controlled trials to investigate the benefits and harms of PTH therapy and conventional therapy in the management of patients with chronic hypoparathyroidism. To identify eligible studies, published in English, we searched Embase, PubMed, and Cochrane CENTRAL from inception to May 2022. Two reviewers independently extracted data and assessed the risk of bias. We defined patients' important outcomes and used grading of recommendations, assessment, development, and evaluation (GRADE) to provide the structure for quantifying absolute effects and rating the quality of evidence. Seven randomized trials of 12 publications that enrolled a total of 386 patients proved eligible. The follow-up duration ranged from 1 to 36 months. Compared with conventional therapy, PTH therapy probably achieves a small improvement in physical health-related quality of life (mean difference [MD] 3.4, 95% confidence interval [CI] 1.5-5.3, minimally important difference 3.0, moderate certainty). PTH therapy results in more patients reaching 50% or greater reduction in the dose of active vitamin D and calcium (relative risk [RR] = 6.5, 95% CI 2.5-16.4, 385 more per 1000 patients, high certainty). PTH therapy may increase hypercalcemia (RR =2.4, 95% CI 1.2-5.04, low certainty). The findings may support the use of PTH therapy in patients with chronic hypoparathyroidism. Because of limitations of short duration and small sample size, evidence from randomized trials is limited regarding important benefits of PTH therapy compared with conventional therapy. Establishing such benefits will require further studies. © 2022 The Authors.
