Understanding brain responses in patients with sensitive teeth

Identification and Quantification of Neurological Responses in Patients with Dentine Hypersensitivity

Observational Sheffield Teaching Hospitals NHS Foundation Trust · NCT06633627

This study is testing how the brains of people with sensitive teeth react to things like cold air or temperature changes to better understand their pain.

What this trial studies

This observational study aims to investigate the neurological responses in patients suffering from dentine hypersensitivity using electroencephalography (EEG). By measuring brain activity in response to stimuli such as cold temperatures and air bursts applied to sensitive teeth, the study seeks to identify how these responses differ in individuals with dentine sensitivity. The non-invasive EEG procedure involves placing electrodes on the scalp to record brain signals during the stimulation. This research could provide valuable insights into the mechanisms of pain associated with dentine hypersensitivity.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with self-reported dentine sensitivity confirmed by a response to air puff.

Not a fit: Patients with untreated dental caries, periodontal issues, or those using orthodontic appliances may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of dentine hypersensitivity, enhancing patient quality of life.

How similar studies have performed: While there have been studies on pain mechanisms in dentistry, this specific approach using EEG for dentine hypersensitivity is relatively novel.
