Gradual reduction in the STOP score in patients with obstructive sleep apnea undergoing oral appliance therapy

Purpose In the treatment of obstructive sleep apnea (OSA), there is not yet a convenient tool for deciding whether mandibular advancement oral appliance (OA) adequately adjusted or when to perform post-treatment sleep-testing. We hypothesized that gradual reduction in STOP (snoring, tiredness during daytime, observed apnea, high blood pressure) score, i.e., fewer Yes responses questionnaire, patients undergoing OA could be an indicator better adjustment and, thus, best timing follow-up polysomnography.
