Borreliosis (Lyme disease) is a chronic multisystem infectious disease transmitted by Ixodes ticks. The etiological agent of borreliosis is the spirochete Borrelia burgdorferi. The symptoms of borreliosis can vary depending on the attacked system and length of infection. Diagnosis is based mainly on clinical symptoms and immunoserological tests. The clinical symptoms of borreliosis also include dysfunction in the tissues and organs of the stomatognathic system. This paper describes a case of a female patient who had experienced a long-term dysfunction of the temporomandibular joint (TMJ). After careful analysis, the symptoms were found to be caused by a chronic form of neuroborreliosis with exacerbations. The findings in this case study show that borreliosis should be considered by doctors and dentists in the differential diagnosis of pain in the area of the TMJ.
