“…PBS is an uncommon manifestation; however, dentists are concerned mainly with the mechanical aspects of occlusion, adding further complications to PBS. In a previous study, we had reported that PBS patients with a dental trigger had significantly less psychiatric history than those without a dental trigger . Hence, the symptoms of PBS cannot be explained by a mental disorder alone.…”

“…All participants in this study had been diagnosed with PBS by a specialist in psychosomatic dentistry, based on the criteria suggested by Melis, as follows: (a) complaints of an uncomfortable sensation while biting; (b) significantly associated emotional distress; (c) symptoms lasting more than 6 months; (d) history of failures of various bite‐altering dental procedures; (e) absence of dental occlusion discrepancies or those disproportional to the complaint; and (f) not attributed to another disorder (dental, pathology, muscle, temporomandibular joint or neurological disorder). Our data included patients who had been analysed in one of our former studies . Exclusion criteria were the presence of a history of organic brain disorder, obvious neurological disorders in the trigeminal nerves and patients with communication difficulties.…”

BackgroundPhantom bite syndrome (PBS) is characterised by occlusal discomfort without corresponding dental abnormalities. Despite repeated, failed dental treatments, patients with PBS persist in seeking bite correction. PBS has been regarded as a mental disorder. However, we have reported that PBS patients with a dental trigger tend to have less psychiatric history than those without. Hence, the symptoms of PBS cannot be explained by a mental disorder alone, and it is unclear if mental disorders affect occlusal sensation.ObjectiveTo elucidate the pathophysiology of PBS, we analysed the dental history, PBS symptom laterality and psychiatric history of patients.MethodsIn this retrospective study, we reviewed outpatients with PBS who presented at our clinic between April 2012 and March 2017. Their medical records were reviewed for demographic data, medical history and laterality of occlusal discomfort.ResultsApproximately half of the 199 enrolled patients had bilateral occlusal discomfort. In the others, the side with occlusal discomfort generally tended to be the one that had received dental treatment. There was no significant relationship between the side chiefly affected by occlusal discomfort and whether dental treatment had been received; however, the affected side differed depending on whether the patient had comorbid psychiatric disorders (P = .041).ConclusionsThe distributions of the side with symptoms of PBS were different between those with and without comorbid psychiatric disorders, suggesting that psychiatric disorders might affect occlusal sensation due to a subtle dysfunction in brain areas central to sensory integration. Central dysfunction might play an important role in PBS.

“…As routine practice, oral medication [3,4] and cognitive behavioral therapy [5] are recommended for treatment of OD patients. Recently, neuromodulation therapy has been clinically recommended for treating cognitive deficits in psychiatric disorders [64][65][66][67][68].…”

“…Persistent occlusal discomfort is a common complaint among occlusal dysesthesia (OD) patients [1][2][3][4] who, in the presence of depression, schizophrenia, panic, or somatoform disorders [5][6][7][8], present with numerous neuropsychological associations. From a clinical standpoint, Tsukiyama et al [2] recommended a psychosomatic evaluation for diagnosis, and Reeves JL and Merrill RL [5], and Toyofuku et al [7] also recommended cognitive behavioral therapy and antidepressants for the treatment of OD patients.…”

Prefrontal modulation during chewing performance in occlusal dysesthesia patients: a functional near-infrared spectroscopy study

et al. 2018

Objectives Neuropsychological associations can be considerable in occlusal dysesthesia (OD) patients who routinely complain of persistent occlusal discomfort, and somatization effects in the superior medial prefrontal cortex and the temporal and parietal regions are also present. However, the relationship between physical activity, i.e., chewing, prefrontal cognitive demand, and psychiatric states in OD patients remains unclear. We investigated this relationship in this study. Materials and methods OD patients (n = 15) and healthy control (n = 15; HC) subjects were enrolled in this study. Occlusal contact, chewing activities of the masticatory muscles, prefrontal activities, and psychiatric states such as depression and somatization, of the participants were evaluated. Functional near-infrared spectroscopy was used to determine prefrontal hemodynamics and the Symptom Checklist-90-R was used to score the psychiatric states. Results We observed a significant association between prefrontal deactivation during chewing and somatization subscales in OD patients. Further, there were no significant differences with regard to the occlusal state and chewing physical activities between the OD patients and HC subjects. Conclusions Chewing-related prefrontal deactivation may be associated with somatization severity in OD patients. Clinical relevance fNIRS is a functional imaging method that uses the principal of neuro-vascular couplings. It is applicable for evaluation of psychiatric state based on prefrontal cortex blood flow in patients with psychiatric disorders.

“…However, in a survey of patients with temporomandibular disorders (TMD), over 30% reported some bite discomfort, and about 10% reported uncomfortable bite almost all of the time . It seems to be differently distributed between the genders with higher female prevalence , similarly to the higher female prevalence of TMD that sometimes are comorbid with the disease . However, such female preponderance is not reported in all the studies .…”

Occlusal dysesthesia (OD) is a disorder characterised by the sensation of uncomfortable bite with no obvious occlusal discrepancy. It is usually associated with emotional distress and is elicited by dental occlusal procedures. Multiple dental treatments are often provided to try to resolve the symptoms, but the outcome is usually dissatisfying for the dentist and disappointing for the patient. To summarise the specific features of OD, a PubMed search was carried out looking for all papers related to the topic. The references from the studies selected and from review articles were also examined for further relevant papers. A total of 138 articles were first identified, of which 18 of them were considered relevant to the topic. This article reviews the epidemiology, taxonomy and etio-pathophysiology, symptomatology, diagnosis and treatment of OD, with special relevance to issues of clinical importance and dental therapy. Any dental treatment must be avoided in patients with OD, because the results could be inadequate and it usually worsens the symptoms.

Psychiatric comorbidities and psychopharmacological outcomes of phantom bite syndrome

Abstract: PBS is generally not associated with severe psychiatric disorders. Absence of a dental trigger predicts a psychiatric comorbidity, which affects the psychopharmacological outcome. Antidepressant or antipsychotic therapy may be effective for symptom management in PBS.
