A randomized, controlled study of a mandibular advancement splint for obstructive sleep apnea. Efficacy of positive airway pressure and oral appliance in mild to moderate obstructive sleep apnea. advancement devices in 630 men and women with obstructive sleep apnea and snoring: tolerability and predictors of treatment success. Assessment of upper airway dynamics in awake sleep apnea patients wi...

We postulated that three extremely obese Yucatan miniature pigs would have more sleep apnea than three nonobese Yucatan miniature pigs. Pigs were studied with the use of electroencephalograms, inductance plethysmography, oximetry, expired nasal CO2, or thermistors. All of the obese pigs, but none of the nonobese pigs, had both sleep apnea (8.5, 10.3, and 97.0 in obese pigs vs. O apnea + hypopne...

Clinical observation suggested that speech disorder seemed to be associated with sleep apnea. We recorded a standard speech sample from 39 matched subjects in three groups, 13 sleep apnea individuals, 13 subjects with COPD, and 13 subjects without sleep apnea or COPD. Three speech pathologists in a single blind listening task of the recorded samples judged whether or not speech disorder was pre...

OBJECTIVE Obstructive sleep apnea is characterized by increased upper airway collapsibility during sleep. The present study investigated the use of the negative expiratory pressure test as a method to rule out obstructive sleep apnea. METHODS Flow limitation was evaluated in 155 subjects. All subjects underwent a diurnal negative expiratory pressure test and a nocturnal sleep study. The sever...

OBJECTIVES The purpose of this study was to investigate the effect of a mandibular advancement device on different grades of obstructive sleep apnea using a relatively simple test for the apnea-hypopnea index to determine if a mandibular device will be effective. MATERIAL AND METHODS A total of 68 patients with obstructive sleep apnea syndrome (OSAS) including, 31 with mild, 23 with moderate ...

OBJECTIVE To test a prediction model for sleep apnea based on clinical and sociodemographic variables in a population suspected of having sleep disorders and submitted to polysomnography. METHODS We included 323 consecutive patients submitted to polysomnography because of the clinical suspicion of having sleep disorders. We used a questionnaire with sociodemographic questions and the Epworth ...

Sleep apnea is defined as repetitive episodes of decreased or total cessation of respiratory airflow during sleep, leading to a fall in oxygen saturation of 4% and sleep fragmentation. Sleep apnea can be central or obstructive. Central sleep apnea (CSA) is characterized by apneas secondary to diminution or cessation of thoraco-abdominal respiratory movements (due to dysfunction of central respi...

Over the past 20 years, increasing data have accumulated underscoring the public health importance of sleep apnea with growing evidence of its high prevalence and myriad clinical manifestations. This condition, rarely diagnosed in the past, had been considered to occur predominantly as a manifestation of morbid obesity and considered to affect almost exclusively middle-aged men. Sleepiness and ...

Obstructive sleep apnea is a sleep disorder of airflow at the nose and mouth during sleep. Patients with undiagnosed sleep apnea represent a major public health problem. Dental professionals have a unique doctor patient relationship that can help them in recognizing the sleep disorder and managing the patients along with a physician or a sleep specialist. Oral appliance therapy is an important ...
