Introduction:

temporomandibular disorders are a set of conditions of the temporomandibular joint, masticatory muscles and associated structures, of multifactorial origin. Likewise, psychological distress and pain are factors that influence the progression of this disorder, and it has been suggested that it affects the quality of sleep.

Objective:

to identify the relationship between temporomandibular disorders and sleep quality.

Methods:

a systematic review of the literature was carried out by searching and analyzing information in the PubMed, SciELO and Scopus databases. Ten scientific articles that met the inclusion criteria were considered.

Results:

temporomandibular disorders are closely related to pain, which results in a significant alteration of sleep quality. These were present to a greater extent in the female sex and disturbed the normal biopsychosocial performance of the individual at any age. Similarly, individuals with high levels of stress may contribute to the progression and exacerbation of painful symptomatology of temporomandibular disorders effecting poor sleep quality.

Conclusions:

we found a high prevalence of sleep disorders in patients with temporomandibular disorders. Sleep quality was affected by the presence of temporomandibular pain, which varied depending on pain intensity. There are divergent data on the direction of the relationship between temporomandibular disorders and sleep quality, and studies are needed to confirm which is the cause and which is the effect.
