Oral Impacts on Daily Performances (OIDP)

The Oral Impacts on Daily Performances (OIDP) is an 8-item interview-administered instrument measuring the functional and social impact of oral conditions on everyday activities. Developed by Adulyanon and Sheiham in 1997, it captures how oral problems (pain, difficulty eating, appearance concerns) disrupt routine daily performances such as eating, speaking, cleaning teeth, sleeping, smiling, and work concentration. The OIDP is particularly valuable in developing countries and resource-limited settings where functional impairment is the primary concern.
