You may have seen our tooth-related quality of life questionnaire, and even been asked to fill one in before your treatment and again some time after your treatment is complete. But what do we do with your answers? Quality of life is a really important part of our evaluation of patient satisfaction and, by identifying areas of concern at the consultation stage, also helps us understand what you hope your treatment will achieve. Our first study using this data is currently being written up for publication (anonymised data only), and shows great results in relation to full-arch treatment, where we saw statistically significant improvements in the overall tooth-related quality of life in all patients. The results from this study also suggest a direction of work for us which would incorporate patient expectations into the treatment planning process.
