untreated decay often drives patients to emergency rooms (ERs), where the lack of definitive dental treatment results in nearly 75% of these patients receiving analgesics, predominantly opioids. Addressing the need for non-opioid pain alternatives is crucial. Emerging evidence suggests that dental pain from pulpal and periodontal conditions (affecting the tooth's nerve and surrounding tissues) involves neuropathic mechanisms, such as mechanical allodynia (MA) and central sensitization (CS). These mechanisms can amplify pain perception, causing typically non-painful actions, like chewing, to become painful and resulting in hypersensitivity extending beyond the affected tooth. Reliably identifying these mechanisms with quantitative measures can support improved pain assessment and targeted non-opioid treatment. This minimally invasive prospective cohort study will use the FDA-approved Innobyte® device, a precise bite-force measurement tool, to evaluate periodontal health and to quantify mechanical pain thresholds in patients requiring endodontic treatment (root canal therapy).",[82,83,84],"Irreversible Pulpitis","Apical Periodontitis","Pulpal Necrosis","2025-07-22",{"date":87,"type":88},"2025-07-24","ACTUAL",{"date":90,"type":88},"2025-05-16",{"date":92,"type":78},"2026-11-01",{"name":5,"class":6},1]
