During periodontal surgery, air polishers can prepare root surfaces detoxify them effectively and efficiently, and leave a uniformly smooth root surface that is clean and free of diseased tissues. Dentinal tubules are then occluded, which may result in decreased sensitivity. Superior growth and vitality of human gingival fibroblasts was evident when ultrasonic scaling was followed by air polishing, compared to ultrasonic scaling alone. Air polishing produced root surfaces that were comparable to manually rootplaned surfaces, and provided better access to furcations. Tissue healing following air polishing was comparable to that achieved by hand instrumentation in root preparation during periodontal flap surgery.
Research findings also support the use of air polishing with orthodontic patients. It is the most efficient and effective method for plaque and stain removal around orthodontic brackets, bands, and arch wires. It is not contraindicated on orthodontic bracket composite resin adhesive systems.
In restorative dentistry, air polishers have provided stronger composite repairs than traditional etching gels. They also are superior to rubbercup polishing in preparing occlusal surfaces for etching prior to sealant placement because the rubber cup forces debris into the fissures. Air polishing of occlusal surfaces also allows for deeper penetration of the sealant resin into the enamel surface than rubber cup and pumice cleaning of the fissures. Air polishers also have enhanced sealant bond strength compared to traditional polishing with a low-speed handpiece, bristle brush, pumice, and water.
