Summary

This study aims to see if an Arabic translation of a short 8-question survey about jaw function is accurate and reliable for people with jaw joint disorders. Researchers will ask 100 Arabic-speaking adults with jaw pain or limited movement to complete the survey. The goal is to provide a trusted tool for doctors to measure how jaw problems affect daily life.
