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. Participants 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.
