Is there any association between sleep bruxism and temporomandibular joint dysfunction?
There is a positive association that exists between sleep bruxism and temporomandibular joint dysfunction (TMD) suggests a new study published in the Journal of Craniomandibular & Sleep Practice
A study was conducted to answer the question, “Is there any association between sleep disorder and temporomandibular joint dysfunction (TMD) in adults?”
In the literature search, 3425 articles were found. After the exclusion of duplicates, 2752 were selected for reading the title and abstract, of which 26 were read in full, and 18 met eligibility criteria.
Based on a systematic review of 18 clinical studies (with mostly low risk of bias), the authors reported that the association between sleep bruxism and the development of temporomandibular joint dysfunction (TMD) in adults is unclear owing to conflicting results. However, positive associations exist between TMD and the following conditions: obstructive sleep apnea, insomnia, snoring, and gastroesophageal reflux.
