Evaluating the Reliability of Risk Factors for Obstructive Sleep Apnea in Subjects with Temporomandibular Joint Dysfunction.
Abstract: Introduction: The objective of this study was to investigate potential OSA in TMD subjects with two or more traditional risk factors (high risk) versus one of fewer (low risk). Our study found 57.7% of subjects positive for OSA in the high risk category and 5.3% positive for OSA in the low risk category, suggesting those with two or more risk factors are much more likely to have OSA than... read morethose with one or fewer risk factors. Materials and Methods: A group of 45 male and female subjects who met the criteria for a positive TMD diagnosis utilized an ambulatory home sleep study for two consecutive nights. The second night of data was analyzed for apnea - hypopnea index per hour of sleep (AHI) to screen for OSA. The population of subjects was typical of TMD patients seeking treatment and consisted of 82% women, average BMI of 27, and mean age of 39.5 years. Results:Of the subjects with two or more risk factors, 58% had OSA versus a 5% OSA rate in the low risk group of one or fewer risk factors, p = 0.0003. Of the snoring females, 44% were found to have OSA. Overall, OSA was present in 35.56% of the TMD subjects. Conclusions: In this study, 58% of TMD subjects with two or more traditional risk factors (snoring males, overweight males, snoring overweight males, and snoring overweight females) tested positive for OSA and would be easily recognized by a dentist or physician for referral and treatment of the OSA. The results of this study suggest that individual risk factors must also be considered in female TMD subjects, such as snoring and overweight BMI (>25). Awareness by the dentist and physician of non-traditional risk factors in patients with TMD, along with ambulatory home sleep study screening, could improve treatment outcomes for this group of pain sufferers and should be considered as the minimum standard of care.
