Sleep Studies

Sleep Accreditation LogoWe treat patients ages 7 and up for a wide array of sleep disorders. Our center physicians are board-certified sleep specialists trained to diagnose and treat sleep problems. Most patients enjoy greatly improved quality of life when normal sleep patterns are restored.

The DENT Sleep Center has a fully equipped diagnostic laboratory, including six private suites where patients sleep while being monitored by trained technicians. These procedures are used to diagnose an array of sleep disorders, including sleep apnea, insomnia, restless leg syndrome (RLS), excessive sleepiness, narcolepsy, and other abnormal sleep behaviors.

Testing at Our Center


Polysomnography normally requires an overnight stay in one of our private suites. During this stay, while you sleep, you will be monitored for Sleep Staging, Eye Movement, Nasal/Oral Airflow, Chest and Abdominal Respiratory Movement, Chin and Limb EMG, EKG and Pulse Oxymetry.

Preparing for your test

  • Bring your pajamas, toothbrush and other morning essentials.
  • For better sleep, bring your own pillow.
  • Discontinue any medicinal sleep aids.
  • On the day of the test, avoid caffeinated drinks such as coffee, tea and cola.


Your head is measured so that all electrodes fit comfortably and securely. Removable marks are made on your scalp where electrodes will be placed. Several others are placed on your chest and legs. Special jelly is applied to each electrode, which is then glued to your scalp and skin with an air blower. To measure your breathing, a plastic belt is placed around your chest. Wires are placed by your nose and mouth to monitor air flow during breathing, and a probe to measure the oxygen saturation of your blood is taped to your finger. Set-up may take 30 minutes or more.

Multiple Sleep Latency Testing

The multiple sleep latency test records your brain waves (EEG), heart rate (EKG), muscle activity and eye movements.

Preparing for your test

  • Your hair should be clean, free of oil or hairspray, and dry.
  • Meals and medication may be taken.
  • On the day of the test, avoid caffeinated drinks such as coffee, tea, and cola.


Small electrodes will be attached to the scalp, around the eyes, under the chin, and on the shoulders. Before the recording, the technician may ask you to complete simple tasks such as looking left and right with your eyes only. During the test, you will lie in a prone position in a relaxed and quiet atmosphere to induce sleep. You will be monitored for about 20 minutes every two hours. You will be awakened and asked to stay awake until the next sleep time. During this time you may read, listen to music, watch television, or have a visitor. The test takes about 7 hours and is often done following an overnight sleep study.


CPAP delivers air into your airway. The mask does not breathe for you, but creates enough pressure when you inhale to keep your airway open.
