title: Effects of sleep bruxism related tinnitus on quality of life.
abstract: OBJECTIVE
  This study aims to analyze the subjective and objective characteristics of tinnitus in sleep bruxism patients.
  
  
  METHODS
  The study included 57 patients (12 males; 45 females; mean age 33.89±12.50 years; range 19 to 55 years) with sleep bruxism and tinnitus (sleep bruxism group) and 24 patients (6 males, 18 females; mean age 43.75±16.19 years; range 21 to 58 years) only with tinnitus (control group). Sleep bruxism was diagnosed by the diagnostic criteria of American Academy of Sleep Medicine. Patients were performed pure tone audiometry to detect hearing thresholds at standard and high frequencies. Tinnitus frequency and loudness were assessed. Subjective aspects of tinnitus were identified by tinnitus handicap inventory.
  
  
  RESULTS
  The statistical analysis revealed that the sleep bruxism group had significantly lower hearing thresholds except 1000 Hz and 2000 Hz. Tinnitus frequency was between 3000 Hz and 18000 Hz in sleep bruxism group while it was between 6000 and 16000 Hz in control group with no statistically significant difference (p=0.362). Sleep bruxism group had significantly lower tinnitus loudness and tinnitus handicap inventory scores in comparison to control group (p=0.024 and p=0.000, respectively).
  
  
  CONCLUSIONS
  Tinnitus caused by sleep bruxism and temporomandibular joint issues has higher frequency and lower loudness compared to patients with only tinnitus.
