Research summary
Loosing teeth can affect our lives. Dental implants are one method to replace missing teeth. Dental implant treatment improves our quality of life, but peoples’ meaning of quality of life might change over time so that it is difficult to measure the benefits of treatment. These changes in peoples’ meaning of quality of life are called “Response Shift”.
Response Shift may allow people to adapt to any benefits of treatment, so they may no longer realize their health has improved. Thus, understanding the influence of Response Shift in quality of life is crucial in evaluation of treatments.
People being treated with dental implants are good patients for studying Response Shift because implants make big changes to quality of life. Thus, this research will investigate how patients’ judgements of dental implant treatments change over time.
We will give questionnaires to patients during and after their courses of treatment to replace missing teeth with dental implants. We will use special questions and complex statistics (Recursive Partitioning Regression Trees) to see if patients’ meaning of quality of life changes.REC name
