According to the recommendations of the professional societies, the adjunctive use of antibiotics in the context of periodontal therapy should be limited to the following indications:
- aggressive, rapidly progressive forms of periodontitis
- therapy-resistant periodontitis
- severe chronic periodontitis
- moderate-to-severe cases of periodontitis in patients with systemic diseases or conditions that interfere with immune function
- peri-implant infections
It should be noted that the occurrence of periodontopathogenic bacteria differs depending on the individual patient and the efficacy of antibiotics is limited to specific groups of bacteria. For this reason, according to the German Society of Dental and Oral Medicine (DGZMK), for the selection of a suitable antibiotic, the existing periodontal infection should be determined by microbiological analysis of the subgingival plaque.
