Temporomandibular disorder and other causes of orofacial pain: first international classification and new treatment perspectives

The diagnosis and treatment of orofacial pain is in many cases a complex task due to difficulties in history taking, multi‑faceted pathology, psychiatric comorbidities and psychosocial factors involved in such pain. Neurologists tend to overdiagnose trigeminal neuralgia. However, other types of neuropathiс orofacial pain are also common. Moreover, neurologists are often unfamiliar with the temporomandibular disorder and tend to neglect this extremely prevalent cause of orofacial pain. Correct understanding of the causes of orofacial pain is vital not only for treatment selection, but also to minimize the risk of adverse events associated with unnecessary madications. Moreover, untreated orofacial pain often becomes chronic and treatment resistant. Many patients in this case would require physical therapy, pharmacological treatments, cognitive behavioral therapy and other support options. The aim of this paper is to review the new International classification of orofacial pain as well as the prevalence, pathophysiology and treatment of the temporomandibular disorder, trigeminal neuralgia, persistent idiopathic facial pain, burning mouth syndrome and other forms of orofacial pain.

Perspectives on next steps in classification of oro-facial pain - part 2: role of psychosocial factors.

This study was initiated by a symposium, in which the present authors contributed, organised by the International RDC/TMD Consortium Network in March 2013. The purpose of the study was to review the status of biobehavioural research - both quantitative and qualitative - related to oro-facial pain (OFP) with respect to the aetiology, pathophysiology, diagnosis and management of OFP conditions, and how this information can optimally be used for developing a structured OFP classification system for research. In particular, we address representation of psychosocial entities in classification systems, use of qualitative research to identify and understand the full scope of psychosocial entities and their interaction, and the usage of classification system for guiding treatment. We then provide recommendations for addressing these problems, including how ontological principles can inform this process.

Perspectives on next steps in classification of oro-facial pain - part 1: role of ontology.

The purpose of this study was to review existing principles of oro-facial pain classifications and to specify design recommendations for a new system that would reflect recent insights in biomedical classification systems, terminologies and ontologies. The study was initiated by a symposium organised by the International RDC/TMD Consortium Network in March 2013, to which the present authors contributed. The following areas are addressed: problems with current classification approaches, status of the ontological basis of pain disorders, insufficient diagnostic aids and biomarkers for pain disorders, exploratory nature of current pain terminology and classification systems, and problems with prevailing classification methods from an ontological perspective. Four recommendations for addressing these problems are as follows: (i) develop a hypothesis-driven classification structure built on principles that ensure to our best understanding an accurate description of the relations among all entities involved in oro-facial pain disorders; (ii) take into account the physiology and phenomenology of oro-facial pain disorders to adequately represent both domains including psychosocial entities in a classification system; (iii) plan at the beginning for field-testing at strategic development stages; and (iv) consider how the classification system will be implemented. Implications in relation to the specific domains of psychosocial factors and biomarkers for inclusion into an oro-facial pain classification system are described in two separate papers.

Perspectives on next steps in classification of oro-facial pain - Part 3: biomarkers of chronic oro-facial pain - from research to clinic.

The purpose of this study was to review the current status of biomarkers used in oro-facial pain conditions. Specifically, we critically appraise their relative strengths and weaknesses for assessing mechanisms associated with the oro-facial pain conditions and interpret that information in the light of their current value for use in diagnosis. In the third section, we explore biomarkers through the perspective of ontological realism. We discuss ontological problems of biomarkers as currently widely conceptualised and implemented. This leads to recommendations for research practice aimed to a better understanding of the potential contribution that biomarkers might make to oro-facial pain diagnosis and thereby fulfil our goal for an expanded multidimensional framework for oro-facial pain conditions that would include a third axis.

Pain paper 2b: classification of orofacial pain and an update on assessment and diagnosis.

The classification of chronic orofacial pain remains a contentious area. However, more recently, with the clarification of pain mechanisms and improved understanding of the underlying neurophysiology and modulation factors, there is more clarity of the possible division of pain conditions. Interestingly, the pathophysiology provides a basis for classification that has more clinical relevance. The principles of assessing and managing patients with pain have modified significantly, in line with recent improved understanding of the affective and emotional components in pain behaviour and suffering. Clinical Relevance: This paper aims to provide the dental and medical teams with a review of the classification of trigeminal pain with an overview of how to assess and diagnose patients with trigeminal pain.

Overlap Between Orofacial Pain and Vulvar Vestibulitis Syndrome

To explore the prevalence of orofacial pain (OFP) among patients with vulvar vestibulitis syndrome (VVS) and to examine the relationship between signs and symptoms of OFP and clinical characteristics of women with VVS, we investigated differences in psychologic characteristics and severity of painful intercourse. In this cross-sectional exploratory study, 137 women with VVS completed questionnaires that assessed levels of pain, anxiety, somatization, and presence of signs and symptoms suggestive of clinical and subclinical OFP. Demographic data were gathered from medical records. OFP was found to be a highly prevalent (78%) condition among women with VVS. Compared with women who had no OFP symptoms (n=30), those with symptoms (n=64) reported higher levels of anxiety (45.0 vs. 37.8, Bonferroni adjusted P=0.017), somatization (125.2 vs. 96.0, Bonferroni adjusted P<0.001), and psychologic distress (62.8 vs. 56.0, Bonferroni adjusted P=0.002). Although we observed a similar trend among women with subclinical OFP (n=43), this trend only reached statistical significance with respect to somatization. Differences were not detected for demographics, duration of pain, and severity of pain during intercourse across the 3 groups. OFP is a common condition among women with VVS. Because severity and duration of painful intercourse did not differ by OFP classification but psychologic characteristics did, we must begin to question a unidimensional focus on vestibular mucosa as a reason for pain and persistent distress.

PHARMACOTHERAPY FOR OROFACIAL PAIN

The sensation of pain is the means by which the body is made urgently aware of the presence of tissue damage. Pain represents a protective reflex for self-preservation. It is often pain that brings the patient to the dental office but also can be the factor that keeps the patient from seeking treatment at the appropriate time. Pain control is of great importance in dental practice. The clinician has to know the financial neuroanatomy, peripheral and central nervous system pathways, pain modulating system and various categories of pain of the head, neck and and face. Psychological and psychosocial factors also contribute to pain, whether pain arises endogenously from pathologic processes or exogenously from trauma or even dental treatment. The dentist’s task is threefold: first, to establish the correct diagnosis, second to find the cause of the pain, and third to select the treatment plan that addresses the patient’s complaint. By knowing the classification of orofacial pain, the clinician will easily make a diagnosis and determine the cause of the pain. After establishing the physical diagnosis it is easy then to determine the therapy to be made. The treatment in managing dental pain from pharmacotherapy is still effective using analgesic and local anasthetic drug.
