Aim To evaluate an individually tailored oral health educational programme on patient-reported outcome compared with a standard oral health educational programme, assess change over time and determine minimal important differences ( MID) in change scores for two different oral health related quality of life ( OHRQoL) instrument after non-surgical periodontal treatment ( NSPT). Materials and Methods In a randomized controlled trial evaluating two educational programmes, patients ( n = 87) with chronic periodontitis completed a questionnaire at baseline and after 12 months. OHRQoL was assessed with the General Oral Health Assessment Index ( GOHAI) and the UK oral health-related quality-of-life measure ( OHQoL- UK). In addition, patients' global rating of oral health and socio-demographic variables were recorded. The MID was estimated with anchor-based and distributions-based methods. Results There were no differences between the two educational groups. The OHRQoL was significantly improved after treatment. The MID was approximately five for OHQoL- UK with a moderate ES, and three for GOHAI with a Small ES, and 46-50% of the patients showed improvements beyond the MID. Conclusion Both oral health educational groups reported higher scores in OHRQoL after NSPT resulting in more positive well-being (OHQoL-UK) and less frequent oral problems (GOHAI). OHQoL-UK gave a greater effect size and mean change scores but both instruments were associated with the participants' self-rated change in oral health. The changes were meaningful for the patients supported by the estimated MID. [ABSTRACT FROM AUTHOR]
