Effects of citric acid treatment on pedicle flap coverage of localized recession.

Abstract

Citric acid conditioning of denuded roots prior to laterally positioned pedicle flap (LPPF) coverage may increase the likelihood of reattachment, but no controlled studies to determine the efficacy of the procedure in managing naturally occurring defects in humans have been reported. This investigation compared the effects of LPPF root coverage with and without citric acid (pH1) pretreatment in a group of patients with gingival recession and associated denuded roots. Thirty-six patients participated in the study. Eighteen received LPPFs without citric acid pretreatment and 18 received LPPFs with citric acid pretreatment. Gingival recession and sulcus depth were measured preoperatively and 30, 60 and 90 days after the surgical procedure. LPPFs both with and without citric acid pretreatment reduced significantly the amount of exposed root, but no differences between groups were found. For sulcus depth, the 90-day value for the citric acid group was significantly increased over the preoperative level, but no other changes were noted. There appears to be no clinical justification for using citric acid conditioning as an adjunct to LPPF coverage of denuded roots.
