Bruxismo nocturno y síndrome de dolor miofascial

Bruxism is an initiating and coadjuvant factor of temporomandibular disorders, including myofascial pain syndrome. However, in the various studies conducted in the scientific literature, there is a lack of consistency in diagnostic methods, the classification of bruxism, or temporomandibular disorders, which has prevented to ensure that there are a cause and effect relationship between bruxism and the different temporomandibular disorders. To try to clarify the relationship between bruxism and myofascial pain syndrome, a systematic review of the literature was carried out on studies that have sought an association about these two conditions. Studies that have found a causal relationship between nocturnal bruxism and myofascial pain have used variable diagnostic methods, relying mainly on surveys, which has limited the possibility of reaching firm conclusions; while those who used objective methods, such as polysomnography, have not found a conclusive causal relationship (AU)
