Third molar surgical procedure and antibiotic use
[ad_1]
The extraction of decrease third molars is a quite common process with an estimated incidence of surgical web site an infection of between 1-13% and between 0.5 – 5% for dry socket (alveolar osteitis). Whereas antibiotic prophylaxis has been proven to scale back dry socket and site-specific an infection the routine use of antibiotic prophylaxis for third molar surgical procedure in wholesome sufferers is questionable within the gentle of accelerating antibiotic resistance.
The intention of this evaluate was to evaluate the position of various antibiotic prophylactic remedies in relation to the danger of growing dry socket (DS) and site-specific an infection (SSI) after decrease third molar extraction.
Strategies
A protocol was registered with the PROSPERO database. Searches had been performed within the Cochrane Library, Medline/PubMed and Scopus databases. Randomised managed trials in sufferers present process decrease third molar extractions receiving prophylactic antibiotics or placebo/no therapy revealed between 1999 and 2021 had been thought of. Three reviewers independently searched and chosen research with information being extracted by two reviewers independently. Two reviewers assessed danger of bias utilizing the Cochrane RoB2 instrument. A pair-wise meta-analysis was performed with outcomes reported as odds ratio (ORs) with the 95% confidence interval (95% CI) adopted by a community meta-analysis (NMA) The efficacy (DS and SSI) and security of the totally different remedies was calculated utilizing the floor beneath the cumulative rating (SUCRA) curve with values starting from 0% to 100%, with greater values suggesting higher efficiency. The knowledge of proof was assessed utilizing the GRADE method.
Outcomes
- 16 RCTs (15 parallel, 1 cross-over) involving 2158 sufferers (2428 third molars) had been included.
- 7 RCTs in contrast amoxicillin+ clavulanic acid, 6 research amoxicillin, two metronidazole and single research azithromycin, and clindamycin in opposition to no therapy /placebo.
Dry Socket (DS)
- 12 RCTs (1755 sufferers, 1995 third molars) assessed DS.
- Meta-analyses favoured antibiotics over placebo/no therapy, OR = 0.54 (95percentCI: 0.33 to 0.90). Quantity wanted to deal with (NNT) = 25.
- The NMA mannequin didn’t reveal any vital variations between the totally different antibiotics.
- The SUCRA rankings are proven within the desk 1 beneath.
- The knowledge of proof was assessed as low.
Table1. – SUCRA rankings for dry socket.
| Antibiotic | SUCRA worth |
| clindamycin preoperative | 73.7% |
| azithromycin preoperative | 71.3% |
| amoxicillin preoperative | 66.3% |
| amoxicillin–clavulanic acid pre- and postoperative | 55.1% |
| clindamycin pre- and postoperative | 50.2% |
| amoxicillin postoperative | 49.1% |
| amoxicillin–clavulanic acid postoperative | 43.7% |
| clindamycin postoperative | 38.8% |
| metronidazole preoperative | 34.0% |
| placebo/no therapy | 17.8% |
Surgical web site an infection (SSI)
- 12 parallel and one cross-over RCT (1746 sufferers, 1986 third molars) assessed SSI.
- Meta-analyses favoured antibiotics over placebo/no therapy, OR = 0.36 (95percentCI: 0.22 to 0.57) Quantity wanted to deal with (NNT) = 18.
- The NMA confirmed a statistically vital distinction when evaluating amoxicillin plus clavulanic acid given pre- and postoperatively with placebo/no therapy.
- The SUCRA rankings are proven within the desk 2 beneath.
- The knowledge of proof was assessed as low.

| Antibiotic | SUCRA worth |
| amoxicillin postoperative | 77.7% |
| metronidazole pre-operative | 74.2% |
| amoxicillin–clavulanic acid pre- and postoperative | 72.7% |
| azithromycin preoperative | 67.5% |
| amoxicillin–clavulanic acid pre-operative | 50.9% |
| amoxicillin–clavulanic acid postoperative | 49.7% |
| amoxicillin preoperative | 43.6% |
| clindamycin post- operative | 25.1% |
| amoxicillin pre- operative and postoperative | 23.7% |
| placebo/no therapy | 15.0% |
Opposed Results
- The most typical antagonistic occasions had been diarrhoea, nausea, vomiting, gastric ache, headache, and mycosis.
- Evaluation of seven RCTs (1484 sufferers, 1724 third molars) discovered no statistically vital distinction in antagonistic occasions between antibiotic and management teams, OR = 0.73 (95percentCI: 0.51 to 1.03).
- The knowledge of proof was assessed as very low.
Conclusions
The authors concluded: –
Though antibiotic prophylaxis was noticed to considerably scale back the danger of dry socket and surgical web site infections in wholesome sufferers present process decrease third molar extraction within the current evaluate, the variety of sufferers wanted to deal with was excessive. The preoperative administration of clindamycin was discovered to be the best therapy to stop dry socket, whereas the postoperative administration of amoxicillin was discovered to be the best therapy to stop surgical web site infections. Since antimicrobial resistance is taken into account an necessary risk to international well being, dentists ought to consider the necessity to prescribe antibiotics for every particular person affected person, bearing in mind the presence of systemic situations and the case-specific danger of growing postoperative infections and/or dry socket after decrease third molar removing.
Feedback
The authors registered their evaluate with the PROSPERO database and adopted a typical systematic evaluate and NMA method with examine inclusion restricted to publications between 1999 and 2021. Beforehand we had thought of one other NMA by Falci et al., (Dental Elf – 24th Jun 2022) with no date restrictions which included 34 RCTs and a Cochrane evaluate by Lodi et al., (Dental Elf – 3rd Mar 2021). Whereas the Cochrane evaluate associated to prevention of issues following tooth extraction 21 out of the 23 research associated to 3rd molar extraction.
These evaluations proven that the usage of antibiotics does scale back the post-operative an infection and dry socket. Nevertheless, the numbers of sufferers wanted to deal with to stop one an infection are excessive and issues associated to antibiotic resistance are growing. Consequently, the routine use of prophylactic antibiotics for third molar surgical procedure ought to be prevented with use being thought of solely after a cautious evaluation of a person affected person’s danger.
