Orofacial pain conditions including temporomandibular joint disorder and migraine are characterized by peripheral and central sensitization of trigeminal nociceptive neurons. Although calcitonin gene-related peptide (CGRP) is implicated in the development of central sensitization, the pathway by which elevated spinal cord CGRP levels promote peripheral sensitization of primary trigeminal nociceptive neurons is not well understood. The goal of this study was to investigate the role of CGRP in promoting bidirectional signaling within the trigeminal system to mediate sensitization of primary trigeminal ganglion nociceptive neurons...

A dentist is expected to be able to recognise and treat pain originating from the teeth. When dealing with short-term, acute pain, the cause can sometimes be found quickly, while this can be much harder in the case of chronic pain. Especially in this latter category, one should be even more careful in diagnostics and choose reversible treatments when possible. A focused anamnesis, a pain journal and trial local anaesthesia can help to identify the suspected cause of the pain. Careful extra- and intraoral examination is needed to reach a proper diagnosis...

Pain is a complex neuro-physiological phenomenon affecting mind and behaviour, and is in turn also affected by psyche and behaviour. Differences among individuals in modulation, interpretation and expression complicate the comparison of pain between patients. Pain is a subjective experience and can be expressed by the patient in many different ways. In addition, influential factors from a bio-psycho-social perspective have to be taken into consideration: the interaction among somatic, psychological and social factors determines the ultimate pain experience and pain behaviour...

Pain is a multidimensional, subjective phenomenon that can only be understood within the context of an individual operating in a specific environment. As a consequence, it is difficult from an objective standpoint to satisfy the established criteria for classification. In general, it is the case that available classification systems can only partially capture pain in all of its complexity. There are various general and specific classification systems. In 2017, the International Classification of Diseases will be complemented with classification possibilities related to chronic pain...

INTRODUCTION: The temporomandibular joint is highly adaptive and masticatory apparatus disorders (MAD) can occur when its ability to adapt is overwhelmed. Occlusal etiologies were long pinpointed as the sole culprits. However, a consensus now exists which minimizes their involvement. It is recognized that the etiology of MAD is multifactorial, combining occlusal problems, parafunctions, postural anomalies, orofacial dyspraxia and stress. MATERIALS AND METHODS: In this article, the authors review the role of physiotherapy in managing these pathologies...

ATP induces pain via activation of purinergic receptors in nociceptive sensory nerves. ATP signaling is terminated by ATP hydrolysis mediated by cell surface-localized ecto-nucleotidases. Using enzymatic histochemical staining, we show that ecto-ATPase activity is present in mouse trigeminal nerves. Using immunofluorescence staining, we found that ecto-NTPDase3 is expressed in trigeminal nociceptive neurons and their projections to the brainstem. In addition, ecto-ATPase activity and ecto-NTPDase3 are also detected in the nociceptive outermost layer of the trigeminal subnucleus caudalis...

Temporomandibular disorders (TMDs) are among the most common maxillofacial complaints and a major cause of orofacial pain. Although current treatments provide short- and long-term relief, alternative tissue engineering solutions are in great demand. Particularly, the development of strategies, providing long-term resolution of TMD to help patients regain normal function, is a high priority. An absolute prerequisite of tissue engineering is to understand normal structure and function. The current knowledge of anatomical, mechanical, and biochemical characteristics of the temporomandibular joint (TMJ) and associated tissues will be discussed, followed by a brief description of current TMD treatments...

Histamine receptors are involved in supraspinal modulation of pain. In the present study, we investigated the effects of microinjection of histamine H1, H2 and H3 receptor antagonists and agonists into the ventral posteromedial (VPM) nucleus of the thalamus on two models of trigeminal pain. Right and left sides of VPM were implanted with two guide cannulas. Corneal pain was induced by local corneal surface application of hypertonic saline and the number of eye wipes was recorded. The duration of face rubbing, as an orofacial pain measure, was recorded after subcutaneous (s...

Orofacial pain research has during the last decades provided important novel insights into the basic underlying mechanisms, the need for standardized diagnostic procedures and classification systems, and multiple treatment options for successful rehabilitation of the patient in pain. Notwithstanding the significant progress in our knowledge spanning from molecules to chair, there may also be limitations in our ability to integrate and interpret the tremendous amount of new data and information, in particular in terms of the clinical implications and overriding conceptual models for orofacial pain...

INTRODUCTION: Chronic myofascial temporomandibular disorders (TMD) may have multiple etiological and maintenance factors. One potential factor, central pain sensitization, was quantified here as the response to the temporal summation (TS) paradigm, and that response was compared between case and control groups. OBJECTIVES: As previous research has shown that fibromyalgia (FM) is diagnosed iñ20% of TMD patients, Aim 1 determined whether central sensitization is found preferentially in myofascial TMD cases that have orofacial pain as a regional manifestation of FM...

Dental education is at the intersection of affordable health care, opioid-abuse crisis, and collaborative practice benefits. Students must engage in interprofessional education (IPE) for pain management. Graduates must recognize appropriate management of acute dental pain and understand the dentist's role in interprofessional treatment of chronic disease, including management of temporomandibular disorders and orofacial neuropathic pain, chronic pain in general, and the consideration of opioids. This article reviews accreditation standards, compares these standards with recommendations from the International Association for the Study of Pain and regulatory boards, and presents examples of enhanced pain education...
