Oral Health Impact Profile (OHIP) as a Tool for the Assessment of the Oral Health-Related Quality of Life-A Scoping Review.

Background/Objectives: The Oral Health Impact Profile (OHIP) is the most widely used tool for OHRQoL assessment. The measure has several versions, but there is no comprehensive summary of available Oral Health Impact Profile variants. The purpose of this scoping review is to identify and summarize Oral Health Impact Profile versions for the adult population available in the literature. Methods: PubMed, Scopus, and Web of Science databases were searched on 25-28 May 2025 to find papers presenting the Oral Health Impact Profile versions' development process. Records written in English without any time restrictions were included. The Joanna Briggs Institute framework for scoping reviews was applied. The PRISMA-ScR approach was followed. Results: In total, 11 generic OHIP scales (the OHIP version that was not targeted at any specific condition) and 16 condition-specified OHIP scales were found. The analysis revealed a wide variety of number of items (from 49 to 5), recall period (from one year to one week), rating scale (4-0; 5-0; 5-1; 6-1; 1, 0, and -1), dimensionality of scale (7, 4, or 3 dimensions, 2-6 factors, or unidimensional), and validation process. Conclusions: Differences in OHIP features have to be taken into account during a comparison of results from different studies. Due to the availability of various tools, the idea of creating new versions of the OHIP should be considered with caution. Researchers should carefully select the appropriate OHIP version for their purposes, as the process of adapting the tool to a new language and culture is time-consuming and expensive.
