title: Coping with stress: its influence on periodontal therapy.
abstract: BACKGROUND
  Individual stress coping strategies appear to influence periodontal disease: individuals with inadequate stress behavior may be at greater risk of developing disease. The purpose of this 24-month prospective study was to examine the influence of different coping behaviors on a non-surgical periodontal therapy and on the course of periodontal disease.
  
  
  METHODS
  In 80 patients with chronic periodontitis, a non-surgical periodontal treatment was conducted after their individual stress coping strategies had been recorded. After 2 years of regular maintenance, their periodontal condition was evaluated. The stress coping questionnaire was used to obtain psychodiagnostic data. Clinical attachment loss (CAL) served as the clinical parameter.
  
  
  RESULTS
  Patients with a defensive coping style had statistically significant poorer attachment values (P= 0.000) after 2 years compared to patients with other coping behaviors. The percentage of sites with slight to moderate CAL (<5 mm) was significantly less in patients with a defensive coping style than in patients with other coping strategies (P = 0.000). The number of sites with severe advanced CAL (>5 mm) was significantly correlated with a suppressive coping style (P= 0.0001). None of the individual stress coping styles revealed significant overall changes over time. The subtest of drug use (alcohol, nicotine, tranquilizers) as well as changes in this subtest over time were significantly correlated with the CAL (P = 0.003); an increase in the t value of the subtest of drug use was accompanied by a significant increase in CAL.
  
  
  CONCLUSIONS
  The results of this study show that passive coping strategies were more pronounced in advanced disease as well as in cases of poor response to a non-surgical periodontal treatment, whereas patients with active coping modes had milder disease and a more favorable course of treatment. Thus, maladaptive behavior, especially in association with behavior-related risk factors such as smoking, are of great importance in the medical history, treatment, and maintenance of patients with periodontal disease.
