🔍 How common is orofacial pain worldwide?
Orofacial pain encompasses several distinct clinical entities, yet its global prevalence has remained difficult to define because available studies differ substantially in diagnostic criteria, methodology and classification. This meta-analysis shows that dentoalveolar and related pain has the highest pooled prevalence at about 27%, followed by myofascial orofacial pain at about 21%, combined myofascial and TMJ pain at 12%, TMJ pain alone at 10%, and cranial nerve-related pain at 8%. These estimates provide a broad epidemiological framework for orofacial pain while emphasizing the importance of more uniform diagnostic and reporting standards in future research.
The findings have several practical implications:
🔸Orofacial pain should be viewed as a major public health issue, not only as an individual clinical complaint.
🔸Standardization matters: broader use of ICOP and DC/TMD could improve diagnostic consistency and cross-study comparability.
🔸Research priorities should include reducing heterogeneity, addressing regional evidence gaps, and improving population-based surveillance.
