Advantages of the analysis with micro-IDent® and micro-IDent®plus

In times of increasing resistance to antibiotics, the use of these important medicines must be rational and diagnostically confirmed. But there are also other reasons that support the use of a microbiological analysis.

Test result forms the basis for individual and effective treatment

Together with the clinical examination, the result of the microbiological analysis provides the dentist with a full picture of the periodontal status. On the basis of this, the dentist can then plan the treatment and tailor the individual steps very specifically to the patient’s needs. The periodontitis can thus be combated in a more targeted and effective manner.

Helps in making a decision for or against adjunctive antibiotic treatment

The result provides information on whether purely instrumental treatment  is sufficient for controlling the infection or whether adjunctive antibiotic therapy is necessary because of the types of bacteria present.

Permits selection of the ideal active substance

Only with a detailed knowledge of the pathogen spectrum is it possible to select an antibiotic that reliably eliminates the individual periodontopathogenic bacteria present, while leaving the beneficial flora undisturbed as far as possible.

Over- or undertreatment is avoided

In some practices, it is common for the Winkelhoff cocktail (combining metronidazole and amoxicillin) to be prescribed indiscriminately for periodontal therapy. Without knowledge of the microbial spectrum, this can mean overtreatment for many patients, however, because single-agent antibiotic therapy would often be sufficient. According to a statistical analysis of almost 170,000 patient specimens (micro-IDent®, Hain Lifescience, Nehren), combination treatment with the Winkelhoff cocktail is actually indicated only in 23.67% of the cases analyzed. Adjunctive treatment with metronidazole would be ideal for the vast majority of patients (68.59% in fact). In other cases, the dentist might decide against antibiotic therapy despite the fact that this would be strongly recommended. A microbiological analysis with micro-IDent® or micro-IDent®plus makes it possible to avoid such errors and thus provides an important decision-making tool for effective treatment planning.

Risk of resistance is minimized

Any unevaluated use of antibiotics considerably increases the risk of resistance because the antibiotic therapy is not tailored specifically to the pathogenic bacteria. One of the consequences of this is that important antibiotics may no longer be effective against a life-threatening infection. This is why antibiotics should always be prescribed only following microbiological diagnostic testing.

Control analyses document the treatment success

Control analyses are available for checking whether the antibacterial treatment was successful. They should not be performed any earlier than 8 weeks after the end of antibiotic therapy. Otherwise, dead bacteria that are still present in the sulcus might lead to a false-positive test result. In the ideal scenario, it should no longer be possible to identify any periodontopathogenic bacteria in the control analysis, but the bacterial load should have decreased significantly at the very least. If that is not the case, sources of error should be analyzed, additional treatment options considered if appropriate and the progress of the disease monitored closely.

For risk assessment prior to implantations

In implantology, analysis of the subgingival flora is particularly worthwhile prior to extensive, costly restorations. In case of a positive test result, targeted elimination of bacteria should always be carried out before implantation starts. Implant loss is thus avoided. If peri-implantitis is already established, then testing serves to select an adequate antibiotic for targeted therapy.

For early identification of recurrence at recall

During the recall phase, regular microbiological analyses help identify reinfection at an early stage. Patients with a positive test result should be investigated further and if necessary transferred back to active treatment.
