Why it matters for dental

Prosthodontists and TMD-focused practices should note that computer-guided occlusal adjustment is linked to measurable reductions in salivary cortisol in muscular TMD patients, suggesting a potential physiologic benefit beyond symptom relief.

Key points

  • Prospective single-arm study published in JPD Sept 2026 (Vol 136, Issue 3) by Goud et al. measured salivary cortisol before and after computer-guided occlusal therapy.
  • Salivary cortisol is a validated stress biomarker; its reduction may correlate with decreased muscular tension and improved patient-reported outcomes.
  • Findings provide early evidence that occlusal adjustment guided by digital force/time analysis can produce objective physiologic change, not just subjective symptom change.
  • No control group reported; clinicians should view results as preliminary and weigh them against placebo or natural history effects when discussing treatment options with TMD patients.
