title: Subcutaneous facial emphysema secondary to use of the Cavi-Jet.
abstract: A case of subcutaneous facial emphysema secondary to use of the Cavi-Jet air polishing system is reported. Air pressure of the Cavi-Jet may exceed that of other dental instruments such as the air/water syringe or air turbine handpiece. Inadvertent angulation of the nozzle tip into a severe periodontal pocket precipitated this condition, which resolved with no serious sequelae. No treatment other than prophylactic antibiotics was prescribed.
