Responsible antibiotic therapy with microbiological diagnostics

Whether additional antibiotic administration is necessary as part of periodontal therapy depends crucially on the concentration and type of bacteria involved. In the presence of high concentrations of invasive bacteria in particular, adjunctive antibiotic therapy may be necessary.

A doctor gives the patient a recipe for antibiotics

Periodontitis and peri-implantitis are a consequence of alterations in the oral microbiome. Depending on the clinical findings, adjunctive antibiotic therapy is therefore necessary in certain cases. However, the composition of the subgingival microflora can vary greatly between individuals. The concentration of the individual marker bacteria also fluctuates considerably between patients. Adjunctive antibiotic therapy should always target the pathogens present specifically while sparing the beneficial flora. For targeted therapy, a microbiological analysis is therefore necessary before an antibiotic is prescribed.

Benefits of diagnostic testing

Microbiological diagnostic testing provides a basis for the informed and rational use of antibiotics and for selecting the most appropriate active substance. Only if the type and quantity of the pathogens present is known, it is possible to answer therapeutically important questions. Is an antibiotic necessary at all? If so, which active substance provides the best coverage of the microbial spectrum present? Over- and undertreatment are thus avoided and the risk of provoking resistances is minimized. Selecting an active substance that targets the periodontal marker bacteria as selectively as possible enables the beneficial flora to be spared and unnecessary side effects to be avoided.
