Bruxism in awake dogs as a clinical sign of forebrain disease: 4 cases
Abstract Background Bruxism is a repetitive masticatory muscle activity characterized by clenching or grinding of the teeth, or by bracing or thrusting of the mandible, or both. Objectives To investigate whether bruxism in awake dogs could be associated with brain lesions. Animals Four dogs with epi...

| description | Abstract Background Bruxism is a repetitive masticatory muscle activity characterized by clenching or grinding of the teeth, or by bracing or thrusting of the mandible, or both. Objectives To investigate whether bruxism in awake dogs could be associated with brain lesions. Animals Four dogs with episodic bruxism in the awake state. Methods Observational retrospective single‐center case series. Inclusion criteria were dogs examined between 2010 and 2021 with episodic bruxism as a presenting complaint or observed during the examination or hospitalization, complete medical records and magnetic resonance imaging or computed tomography of the brain. Bruxism during epileptic seizures as oroalimentary automatism was an exclusion criterion. Results Four dogs met the inclusion criteria. Two dogs had bruxism while awake as a presenting complaint, whereas in the remaining 2 it was a clinical finding. All dogs had neuroanatomical localization consistent with a forebrain lesion, with diencephalic involvement in 3/4. The diagnostic evaluation was consistent with neoplasia (n = 2) and meningoencephalitis of unknown origin (n = 2), in 1 case accompanied by corpus callosum abnormality affecting the forebrain, in 3 dogs advanced imaging findings were suggestive of increased intracranial pressure. All dogs were euthanized. Conclusions and Clinical Importance Our results suggest that the presence of bruxism in the awake state associated with other neurological deficits might indicate a forebrain lesion. |
