Diagnostics in periodontal therapy

In order to be able to respond appropriately to periodontitis, it is necessary to obtain a detailed general medical history. The information this yields determines the subsequent treatment path.

The basic examination covers the whole patient and takes into account all the factors that may have a bearing on the disease course and response to treatment. Among the aspects included are clinical parameters, the X-ray status of the periodontium and the oral hygiene status. Based on the information gathered, it is possible to create a treatment plan that is individually tailored to the patient.


How severe is the periodontitis based on a review of bleeding score, tooth loosening, probing depth and attachment loss?

X-ray status

What bone loss and furcation involvement are shown on the orthopantogram? The periodontal X-ray status can include individual images of all teeth as an option.

Oral hygiene

How well does the patient look after his/her teeth? Tools such as the approximal plaque index (API) and the sulcus bleeding index (SBI) can be used to determine the oral hygiene status.


What other conditions does the patient have (diabetes mellitus, osteoporosis, HIV, cardiovascular disease, joint replacement, etc.)? Is the patient taking any medicines that must be taken into account in treatment planning (blood-thinning medications, antidepressants, immunosuppressants, etc.)?


How high is the periodontopathogenic bacterial load? This question can be answered with a micro-IDent®/micro-IDent®plus marker bacteria analysis. An understanding of the composition of the subgingival flora provides a basis for infection biology-based treatment planning at an early stage. The analysis result can also help to show the patient what his/her individual situation is and to help him/her to understand the need for a careful oral hygiene routine.

Sampling with paper tips


Does the patient have a genetic predisposition to periodontal diseases? An interview with the patient and/or an analysis of his/her individual risk profile based on the human genetic test system GenoType IL-1 can help here.


Do additional risk factors exist? Such as smoking, stress, dry mouth, allergies? A questionnaire or detailed discussion with the patient can be used to clarify this.
