Systematic review and recommendations for nonodontogenic toothache.

Nonodontogenic toothache is a painful condition that occurs in the absence of a clinically evident cause in the teeth or periodontal tissues. The purpose of this review is to improve the accuracy of diagnosis and the quality of dental treatment regarding nonodontogenic toothache. Electronic databases were searched to gather scientific evidence regarding related primary disorders and the management of nonodontogenic toothache. We evaluated the level of available evidence in scientific literature. There are a number of possible causes of nonodontogenic toothache and they should be treated. Nonodontogenic toothache can be categorised into eight groups according to primary disorders as follows: 1) myofascial pain referred to tooth/teeth, 2) neuropathic toothache, 3) idiopathic toothache, 4) neurovascular toothache, 5) sinus pain referred to tooth/teeth, 6) cardiac pain referred to tooth/teeth, 7) psychogenic toothache or toothache of psychosocial origin and 8) toothache caused by various other disorders. We concluded that unnecessary dental treatment should be avoided.

Persistent orofacial muscle pain.

The pathophysiology of persistent orofacial myalgia has been the centre of much controversy. In this article we suggest a novel descriptive term; 'persistent orofacial muscle pain' (POMP) and review current evidence that supports the hypothesis that the induction of POMP involves the interplay between a peripheral nociceptive source in muscle, a faulty central nervous system component and decreased coping ability. In this context it is widely accepted that a complex interaction of variable intrinsic and extrinsic factors act to induce POMP and dysfunction.

Lyme disease: considerations for dentistry.

Although Lyme disease has spread rapidly and it is difficult to diagnose, a review of the dental literature does not reveal many references to this illness. Dental practitioners must be aware of the systemic effects of this often multiorgan disorder. Its clinical manifestations may include facial and dental pain, facial nerve palsy, headache, temporomandibular joint pain, and masticatory muscle pain. The effects precipitated when performing dental procedures on a patient with Lyme disease must also be considered. This study discusses the epidemiology and diagnosis of Lyme disease, its prevention, and factors to consider when making a differential diagnosis. Dental care of the patient with Lyme disease and currently available treatments also are considered. Three case reports are presented.

Differentiation of orofacial pain related to Lyme disease from other dental and facial pain disorders.

The diagnostic process for the orofacial pain patient is often perplexing. Compounding the process of solving a diagnostic mystery is the multiplicity of etiologic factors. The propensity for Lyme disease to present with symptoms mimicking dental and temporomandibular disorders makes the task even more complex. It is hoped that the reader is cognizant of the fact that a pathologic process of dental structures--the teeth and their attachments to the mandible and maxilla, the temporomandibular joints, masticatory musculature, and vascular supply and sensory innervation of the oromandibular anatomy--may also be the source of facial pain. Although unique, similar complaints may also be manifestations of other causes, including pain associated with Lyme disease. The informed and fastidious clinician does not overlook these possibilities when evaluating the headache and facial pain patient. The clinician should be equipped with the knowledge and minimal armamentarium to evaluate the patient appropriately. To paraphrase from Sherlock Holmes, we must first eliminate the impossible, whatever is left is the truth, no matter how unlikely. A differential diagnosis must be achieved based on clinical experience, unbiased observations, and probability.

Chronic orofacial pain. A practical approach to differential diagnosis.

Successful diagnosis of chronic orofacial pain is a difficult task. This article attempted to simplify diagnosis by first classifying the orofacial pain on the basis of clinical characteristics into three basic pain categories: somatic, neurogenous, and psychogenic, and then according to the tissue system affected. An accurate and thorough history is essential, along with a detailed physical examination. In addition, an awareness of the local, systemic, and psychological causes of orofacial pain is necessary. The adage "what you don't know, you don't diagnose" is especially apt in regard to orofacial pain.

Comparison of two patients with similar facial pain complaints of dental and non-dental etiologies.

The medical and lay communities have become more aware of the role of dentistry in the diagnosis and management of facial pain disorders. In some cases, the patient or physician may presume that a facial pain complaint is of odontogenic origin and seek the opinion of a dental practitioner. While the majority of facial pain complaints may be due to dental pathologies, some may also be due to non-dental causes. The diagnostic acumen of the dentist must include a basic understanding of non-dental causes for facial pain as well as those related to dentistry. The following case reports may serve to underscore this observation.

Lyme disease awareness for the New Jersey dentist. A survey of orofacial and headache complaints associated with Lyme disease.

The incidence of Lyme disease is increasing in New Jersey. In 1996, 2,190 cases were reported, representing an increase of 487 cases from the 1,703 reported in 1995 [Table 1]. Symptoms associated with Lyme disease include headache and facial pain that often mimics dental pathology and temporomandibular disorders. Patients with complaints of vague, non-specific dental, facial or head pain, who present with a multisystemic, multi-treatment history, are suspect. This article discusses Lyme disease in New Jersey and the clinical presentation of Lyme disease that the dental practitioner may encounter. A summary of data is provided which was collected from 120 patients diagnosed with laboratory confirmed Lyme disease. The most common orofacial, head and dental complaints seen in the Lyme disease patient are reviewed. This information will hopefully aid in establishing a diagnosis and appropriate referral where indicated.
