[The influence of lifestyle factors on periodontal treatment outcomes].

A 51-year-old woman with periodontitis was being treated at the Department of Periodontology of an academic centre for dentistry. Since the patient s oral hygiene was insufficient, motivational interviewing was applied to encourage her to adopt behavioural changes. Unfortunately, the patient did not sufficiently improve her lifestyle. While she did smoke less, her eating patterns, stress levels and irregular sleeping patterns, all possibly also induced by financial problems, improved insufficiently. This case highlights the importance and challenge of addressing lifestyle factors contributing to the onset and progression of periodontitis.
