Evaluation of 0.12% chlorhexidine rinse on the prevention of alveolar osteitis

A double-blind study evaluated the ability of 0.12% chlorhexidine rinse to decrease the incidence of localized alveolar osteitis after the removal of mandibular third molar teeth. One hundred sixty extraction sites in 80 patients were evaluated. A statistically significant decrease in the incidence of dry socket was seen in patients using the chlorhexidine rinse with no significant adverse reactions. Thus a 0.12% chlorhexidine rinse is shown to be an effective means of decreasing alveolar osteitis that may follow removal of third molar teeth.
