A case of episodic, spontaneous odontalgia, aggravated by ingestion of cold food, with no apparent dental pathology is presented. Attempts at alleviating the pain by means of root canal treatment had failed in previous, similar episodes, and pain and pulpal hyperalgesia had shifted to other locations. ⋯ A prophylactic attempt with nifedipine, a calcium channel blocker, failed to alleviate the pain. This diagnostic entity and possible therapeutic approaches are discussed.

Comparative Study
TMD in patients with primary Sjögren syndrome: a comparison with temporomandibular clinic cases and controls.
The aim of this study was to investigate the prevalence of temporomandibular disorders (TMD) in patients with primary Sjögren syndrome (1 degree SS), analyze the impact of the disease on mandibular function, and assess psychosocial distress. ⋯ Both 1 degree SS and chronic TMD may be associated with appreciable physical discomfort and psychosocial dysfunction. However, the underlying mechanisms of the oral dysfunction of 1 degree SS and TMD are quite different and essentially unrelated.

Randomized Controlled Trial Clinical Trial
Chronic neurogenic facial pain: lack of response to intravenous phentolamine.
Chronic neurogenic facial pain is commonly resistant to treatment and is often the source of significant patient morbidity. Adrenergic mechanisms are postulated to play a role in producing this type of pain, and adrenergic blocking agents are frequently used in clinical practice for pain control therapy. The analgesic effectiveness of an adrenergic blocking agent, intravenous phentolamine, was compared to saline and intravenous lidocaine in the present study using a single-blind protocol in patients with chronic neurogenic facial pain. ⋯ The results do not support an adrenergic mechanism for chronic neurogenic facial pain. The response to lidocaine, a nonadrenergic, membrane-stabilizing agent, suggests that it may have clinical effectiveness in certain neurogenic facial pain patients.

Randomized Controlled Trial Clinical Trial
Trazodone in burning mouth pain: a placebo-controlled, double-blind study.
An 8-week parallel, placebo-controlled, double-blind trial evaluated the efficacy of the antidepressant trazodone in the treatment of chronic burning mouth pain. ⋯ In this controlled trial, trazodone failed to relieve burning mouth pain.

The aim of this study was to determine the prevalence of pain that is related to temporomandibular disorders (TMD), gender differences, and perceived treatment need in children and adolescents at a public dental clinic in Linköping, Sweden. ⋯ Overall, TMD-related pain was more common in girls than in boys. A majority of children and adolescents who experienced pain once a week or more perceived a need for treatment. Seven percent of the examined subjects were diagnosed with TMD pain.
