Antibiotics at replantation of avulsed permanent teeth? A systematic review.

OBJECTIVES: At present there is no clear consensus whether systemic antibiotics should be administered at replantation of an avulsed permanent tooth. This systematic review and meta-analysis assessed the evidence on effectiveness and harms of the administration of systemic antibiotics at replantation of avulsed permanent teeth. METHODS: In August 2020 a systematic literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, for systematic reviews, randomized controlled trials (RCT) and observational controlled studies in MEDLINE, PreMedline, Embase, and the Cochrane databases. The population of interest were medically fit patients with a replanted avulsed tooth. Main outcomes were tooth survival, periodontal healing, pulpal revascularization as well as (severe) adverse events. These outcomes were compared in patients who did and who did not receive systemic antibiotics. The GRADE methodology was used to assess the quality of evidence. RESULTS: The search yielded no RCTs, and none of the 7 included observational studies had the prime intent to investigate the effectiveness or harms of antibiotics. According to GRADE, the overall level of evidence was very low. The meta-analyses showed non-significant associations between the administration of systemic antibiotics on the one hand and tooth survival (1 study, RR = 3.70, 95% CI: 0.63-21.69), periodontal healing (meta-analysis of 6 studies RR: 1.07; 95% CI: 0.80-1.45), and pulpal revascularization (meta-analysis of 2 studies, RR: 0.36; 95% CI: 0.05-2.41) on the other hand. CONCLUSION: Currently there is no high-quality evidence to support the use of systemic antibiotics at replantation of avulsed permanent teeth. Hence, their routine use cannot be recommended in medically fit patients. Well-designed RCTs should be a priority on the research agenda.

Are systemic antibiotics indicated in children presenting with an odontogenic abscess in the primary dentition? A systematic review of the literature.

OBJECTIVES: This systematic review aimed to assess (1) whether systemic antibiotics are beneficial or harmful in healthy children who present with an odontogenic abscess in the primary dentition with or without systemic involvement and (2) if antibiotics are beneficial, which type, dosage and duration are the most effective. MATERIALS AND METHODS: Electronic databases (Medline, Embase, and the Cochrane Library) were screened from 1948 up to August 2020. No filters with respect to study design were applied. Outcomes of interest included pain, swelling, pain relief, adverse effects, signs of infection, quality-of-life measurements and medication required for pain relief. RESULTS: Altogether, 352 titles and abstracts were screened for eligibility; of these, 19 were selected for full text assessment. All were excluded because none of them fulfilled the inclusion criteria and addressed the (adjunctive) use of antibiotics in children who present with an odontogenic abscess in the primary dentition. CONCLUSIONS: At present, there is no single randomised or non-randomised clinical study evaluating the effectiveness and harms of systemic antibiotics administered in children who present with an odontogenic abscess in the primary dentition. CLINICAL RELEVANCE: There is no clinical evidence to support nor to refute the use of antibiotics in children who present with an odontogenic abscess in the primary dentition without signs of local spread or systemic involvement. Given this lack of scientific evidence, the use of antibiotics cannot be recommended in these children. Well-designed clinical trials are indicated to fully understand the impact and necessity of antibiotics in these situations.
