The Treatment of Gingival Recession Associated with Deep Corono-Radicular Abrasions (CEJ step) - a Case Series
Pini-Prato, Giovanpaolo/Baldi, Carlo/Rotundo, Roberto/Franceschi, Debora/Muzzi, Leonardo
The present case series study illustrates two different mucogingival techniques for treating gingival recessions associated with deep dental abrasions. The therapeutic strategies depend on the depth of the abrasion measured at the mid most coronal point at the CEJ level (CEJ step). When the CEJ step was <1 mm, a connective tissue graft associated with an extremely positioned coronal flap was performed. In case of a CEJ step >=1 mm, a double connective tissue graft with an extremely positioned coronal flap was used. The dental abrasions and/or CEJ were not mechanically treated in either situation. One year later, the results showed a recession reduction of 97.5%, with complete root coverage obtained in 82% of sites, and dental hypersensitivity reduction obtained in 5 out of the initial 7 sites. There were no new cases of dental hypersensitivity at the end of follow-up period as a consequence of the treatment. This case series report shows that optimal clinical results in terms of complete root coverage of gingival recessions associated with deep cervical abrasions can be achieved by performing an appropriate surgical procedure without removing dental tissue.
