Periodontal treatment, psychological factors and oral health-related quality of life.
AIMS
To determine changes in OHRQoL and clinical status after periodontal treatment and the factors predicting these changes.


METHODS
Cohort of 140 patients with chronic periodontitis receiving non-surgical treatment. Participant self-completed questionnaires: Sense of Coherence, Locus of Control, Self-esteem and Task-specific Self-efficacy before treatment, and Oral Health Impact Profile at treatment, oral hygiene review and end of study. Relationships between OHRQoL, clinical data, individual and environmental characteristics were analysed with structural equation modelling guided by the Wilson and Cleary model.


RESULTS
OHRQoL and the periodontal status improved after treatment. Greater sense of coherence and age, better periodontal status, lower DMFT and being male predicted better OHRQoL after treatment. Better task-specific self-efficacy and self-esteem, but worse plaque score predicted better end periodontal status.


CONCLUSIONS
OHRQoL and periodontal status improved after periodontal treatment, and this was predicted by individual demographic and psychological factors. These factors may assist with case selection and as possible points for intervention to improve clinical and subjective outcomes of periodontal treatment.
