Validation, measurement properties, and minimal clinically important difference of short-version oral health impact profile (OHIP-5) by type of prosthodontic treatment: a prospective cohort study

The OHIP-5 Thai is a practical and efficient instrument for assessing OHRQoL problems and for evaluating patient outcomes following conventional prosthodontic treatments. Its performance is correlated with longer OHRQoL instruments, making it suitable for both clinical practice and research settings, supporting patient-centered, evidence-based prosthodontic care. The established MID scores offer valuable benchmarks for interpreting clinically meaningful changes. However, its use may be limited in patients with sufficient functional teeth receiving FDP, as it may be unable to capture meaningful changes.
