Screening for obstructive sleep apnea in the dental office setting.

Obstructive sleep apnea (OSA) is a widespread disease with a prevalence of 4 to 9 percent in the world's population. It occurs in all age groups from neonates to senior citizens, but weight, age, race and gender all influence its expression. OSA is as common as asthma and in its severe form can cause fatal cardiovascular damage. Since a dental practice often treats entire families on a routine basis, the setting is a natural place to aid in identifying patients at risk for having OSA.
