The aim is to explore the optimal drug dose and duration of adjunctive Amoxicillin-plus-Metronidazole (AMX/MET) to full-mouth scaling and planing (FMSRP) in periodontitis. An electronic search in four databases and manual search in four journals were conducted for randomised clinical trials comparing AMX/MET adjunct to FMSRP with FMSRP alone for at least 3 months. Eleven studies were eligible and included. The primary outcome was clinical attachment level (CAL) gain, the secondary outcomes were periodontal pocket depth (PPD) reduction and adverse events. Our results showed a beneficial effect of adjunctive AMX/MET with higher drug dose to FMSRP for CAL gain and PPD reduction at 3 months, and the benefit remained stable at 6 months. However, minimal difference among three-seven-and ten-day drug duration was observed. In addition, the risk difference of adverse events was minimal between two groups. FMSRP adjunct to a high drug dose of 500/500 mg of AMX/MET showed a significant and stable improvement on 6-month follow-up period. No decision for drug duration could be made due to limited evidence. On 6-month follow-up, higher dose of AMX/MET adjunct to FMSRP could provide a stable clinical effect. No recommendation for drug duration could be made. © 2021. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
