title: [Relationship between the chronic periodontitis and the depression anxiety psychological factor].
abstract: OBJECTIVE
  To explore the relationship between the chronic periodontitis (CP) and the depression-anxiety psychological factors.
  
  
  METHODS
  Thirty-one patients and 29 age, gender-matched volunteers were enrolled for this study. In order to assess the depression-anxiety psychological index, the subjects filled the questionnaire regarding the demographic and socioeconomic information, the oral hygiene habit, the Center for Epidemiologic Studies Depression Scale (CES-D) and the Self Rating Anxiety Scale(ASA). Calculus index (CI), bleeding on probing (BOP), probing depth (PD), clinical attachment loss (CAL), furcation involvement (FI) and tooth mobility were assessed at 6 sites per tooth of all erupted teeth by a manual periodontal probe. The data were analyzed by the analysis of variance, χ(2) test, and multivariable logistic step wise analysis via the software of SPSS 15.0.
  
  
  RESULTS
  The mean CAL of the control group was 0.46 ± 0.16,the mean CAL of the moderate, high, and severe CP group was 2.84 ± 0.12, 3.51 ± 0.34, and 4.71 ± 0.51, respectively, which is significant difference between each other (P<0.01). The depression index of the volunteers, the moderate CP, the high CP, and the severe CP was 30.52 ± 3.73, 35.83 ± 7.76, 37.25 ± 6.16, 37.82 ± 5.94, respectively. The anxiety index among the 4 groups was 26.69 ± 3.55, 37.67 ± 6.31, 32.87 ± 5.54, and 35.94 ± 6.30, respectively. The depression and anxiety indexes of the periodontitis groups were higher than those of the control (P<0.01) while there was no significant difference among the 3 CP groups (P>0.05). The multivariate logistic analysis of the relationship between CP and the depression-anxiety psychological factors showed that the depression psychological factor was B=2.301,OR=9.988 while the optimistic coping style was B=-5.174,OR=0.006 in the equation of the regression.
  
  
  CONCLUSIONS
  The depression psychological factor was related to the progression of CP. In addition, the optimistic coping style could prevent the progression of the CP.
