Biomarkers in orofacial pain conditions: A narrative review
Bibliographic record
Abstract
Orofacial pain conditions, including temporomandibular disorder, migraine, dental pain, and trigeminal neuralgia, are complex, multifactorial disorders with significant impacts on patients' quality of life. As understanding of the pathophysiology of these conditions has deepened, the role of molecular and genetic biomarkers in diagnosing, monitoring, and potentially treating orofacial pain has garnered increasing interest. This scoping review provides a comprehensive overview of the current state of research on biomarkers associated with orofacial pain conditions. By analyzing existing literature, we identify key biomarkers linked to inflammation, neural activity, and tissue degradation that are common across multiple conditions, as well as those specific to particular disorders. Our findings underscore the potential of these biomarkers to guide the development of personalized therapeutic strategies. However, the review also highlights the challenges faced by current biomarker research, including heterogeneity in study designs, small sample sizes, and a lack of longitudinal data. Addressing these challenges is critical for translating biomarker research into clinical practice and improving outcomes for patients with orofacial pain.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
