Treating obstructive sleep apnea: can an intraoral prosthesis help?

Article Abstract:

A modified intraoral prosthesis appears to be effective in treating patients with obstructive sleep apnea syndrome (OSAS). OSAS occurs when tissues obstruct the upper airway during sleep, causing breathing to stop for brief periods. Researchers used sleep studies and head measurements to study five men with OSAS before and after the men were fitted with dental prostheses. In the four patients who completed all sleep studies, the prostheses reduced the number of apnea episodes by approximately 50% per night and decreased the severity of OSAS. The prostheses increased the average airway space behind the base of the tongue and helped normalize the position of the hyoid bone. These simple, modifiable, clear acrylic devices can be made in the dentist's office. They act to hold the upper jaw in a forward position to keep the airway open.

Aerosol and splatter contamination from the operative site during ultrasonic scaling

Article Abstract:

Ultrasonic dental scalers produce substantial aerosol and splatter, which may contain blood and other potential hazards to dental personnel. Ultrasonic scalers use high-frequency vibration to remove tartar from teeth. Dentists compared several ultrasonic scalers with conventional hand scaling on tooth models. Hand scaling produced virtually no fine aerosols or liquid splatter, but ultrasonic scaling produced aerosol clouds and splatter as far as 26 cm from the instrument tip. High-volume suction evacuators may reduce the risk to dental staff from aerosolized blood and saliva.

The role of oral appliances in treating obstructive sleep apnea

Article Abstract:

A device worn in the mouth that fits over the teeth and pushes the lower jaw forward may be effective for some patients with obstructive sleep apnea. The device creates a larger space inside the mouth, allowing air to flow freely. People with obstructive sleep apnea have a smaller than normal space that blocks the flow of air. This makes them stop breathing temporarily throughout the night.
