BACKGROUND Pain-related worry is distinct from, but related to, pain catastrophizing (PC) and anxiety. Worry and its relationship with other variables have been studied in people with chronic pain but not in people with chronic orofacial pain. The authors explored the prevalence of trait, general and pain-related worry and the association of worry with higher pain levels and other variables. ...

BACKGROUND Temporomandibular joint (TMJ) inflammation in patients with juvenile idiopathic arthritis (JIA) can lead to orofacial pain and malfunction of the TMJ. Intra-articular corticosteroid injections (IACI) have been suggested as a treatment modality against TMJ arthritis-related orofacial signs and symptoms. However, knowledge of the effect-durability of these injections remains unanswered...

AIMS To assess dental students' achieved competencies and perceived satisfaction with their temporomandibular disorders (TMD) and orofacial pain education and to compare these with the results of their final examination in TMD and orofacial pain. METHODS Dental students from two consecutive classes (2011/2012 and 2012/2013) at the Department of Orofacial Pain and Jaw Function at the dental sc...

OBJECTIVES The aim of the current study was to investigate whether there was a relationship between a history of third molar removal and the prevalence of orofacial pain in a sample of the general population. MATERIAL AND METHODS A survey was conducted in South East Cheshire, United Kingdom (81% participation rate). Information was collected using postal questionnaires (n = 1510) and dental r...

In this study, the effects of subcutaneous (SC) injection of pilocarpine (a cholinomimetic agent) and atropine (a muscarinic receptors antagonist) were investigated on a tonic model of orofacial pain in rats. The contribution of the endogenous analgesic opioid system was assessed using naloxone (an opioid receptors antagonist). Tonic orofacial pain was induced by SC injection of a diluted forma...

Orofacial pain is a common complaint and challenging diagnostic problem. Among numerous causes of orofacial pain, the most common are diseases of teeth and periodontium, followed by various diseases and lesions of the oral mucosa. Pain of the oral mucosa is an accompanying symptom of different mucosal lesions caused by local or systematic factors. This type of pain belongs to the category of su...

Orofacial pain, the main reason why many patients seek dental advice, usually has a local cause--primarily the sequelae of dental caries--but a wide range of diseases, particularly neurological, psychogenic and vascular disorders, can cause orofacial pain. This article will discuss disorders that can present with pain and the neurological, psychogenic and vascular causes of orofacial pain. The ...

The aims of the present study were to assess the influence of: a) trait anxiety on orofacial pain; and b) orofacial pain on state anxiety. Forty-four rats were initially exposed to the free-exploratory paradigm for the evaluation of their anxiety profiles. In accordance to the parameter "Percentage of time in the novel side", the animals were considered as presenting high or low levels of trait...

The management of chronic orofacial pain often follows a pattern of claims of efficacy based on clinical observations superseded by equivocal findings of effectiveness or belated recognition of toxicity. While therapeutic innovation spurred by genomics and proteomics is likely to result in new drugs for pain, inflammation, and neuropathic pain, the process of drug development and approval takes...
