Efficacy and Retention of Sealants Placement Using Two Isolation Systems

"DryShield combines the tasks of high-suction evacuator, saliva ejector, bite block, tongue shield, and oral pathway protector in one easy-to-use device.~The DryShield solution® is a patented autoclavable isolation system (MA, USA)"

Cotton Roll Isolation requires placing cotton rolls along the buccal mucosa, especially over the parotid glands ducts for maxillary teeth. For the mandibular teeth, the cotton rolls are placed in the buccal vestibule and the floor of the mouth (between the lower buccal mucosa and underneath and/or between the tongue). With this technique, a high-speed evacuation of saliva and water is used.
