PATIENT PROFILE OF USER MANDIBULAR PROTUSION APPLIANCE

Abstract

The Obstructive Sleep Apnea and Hypopnea Syndrome (OSAHS) is one of the most prevalent subdiagnosticated disorders, with the highest morbidity and mortality among sleep disorders. Symptoms include snoring, breathing pauses, and restless sleep with multiple arousals. The aim of this study was to evaluate clinical records of patients that had the indication to use Mandibular Protrusion Device (MPD) that were referred to dental clinic of Recife, Brazil and that underwent polysomnography exam between 2000 and 2009. This is a retrospective cross-sectional study which analyzed 128 patients for age, sex, body mass index (BMI), apnea and hypopnea index (AHI), snoring, sleep efficiency and REM sleep. There was male predominance (64.8%), 32.8% were between 50 and 59 years old and 48.7% of respondents were in pre-obese (BMI between 25 and 29.9). Women had higher AHI mean (17.75) than men. However, the Mann Whitney U test, p = 0.693 (5% significance), statistically clarified that the AHI did not differ significantly between sexes. The majority (92.3%) of patients with poor sleep efficiency had OSA, though there were no statistical evidences that variables are related. We concluded that the patient referred to use MPD has a predominantly male profile, pre-obese, with symptoms of snoring, moderate AHI and unsatisfactory sleep efficiency.
