Temporomandibular disorders: a review of current concepts in aetiology, diagnosis and management

“…The International Classification of Orofacial Pain (ICOP), the first classification system for all orofacial pain disorders, including TMD, has been recently published. 91 Despite being a new classification, when it comes to TMD most of the criteria and the examination suggested in the ICOP are the same as for the validated DC/TMD. Furthermore, as there has been some improvement in the understanding of the pathophysiology behind TMD and other pain disorders, future taxonomy will most likely begin to include a more mechanistic classification.…”

Psychophysical characterisation of burning mouth syndrome—A systematic review and meta‐analysis

“…Primary burning mouth syndrome (BMS) is a disease defined in the International Classification of Headache Disorders (ICHD-3) 1 and the International Classification of Orofacial Pain (ICOP), 2 as an "Intraoral burning or dysaesthetic sensation, recurring daily for more than 2 hours per day over more than 3 months, without clinically evident causative lesions." Epidemiological studies have estimated a prevalence between 0.01% and 40% with the highest prevalence in post-menopausal women and in older age ranges.…”

“…In this context, the ICOP sub-classifies BMS based on the presence of sensory abnormalities found by QST. 2 Correct classification of pain patients based on underlying pain mechanisms is important as it may influence the management. 18 QST is a standardised method that quantifies sensory alterations to detect changes in fibre and receptor function implicated in neuropathic pain.…”

“…1,2 Furthermore, age and sex matching should be done to reduce selection bias. Regarding performance, a standardised and validated QST protocol, such as the one recommended by the DFNS,19 should be utilised considering the available modifications for the oral cavity 20.…”

The painful tooth: mechanisms, presentation and differential diagnosis of odontogenic pain

“…Pulpal pain attributed to hypersensitivity can be defined as pain occurring in association with a clinically normal pulp, and is a diagnosis included in the recently published International Classification of Orofacial Pain (ICOP) 45 . Hypersensitivity occurs due to stimulation of pulpal nociceptors as a result of exposed dentine, for example due to gingival recession, tooth wear (Fig.…”
